This -is, of course, a sure sign of its continuing popularity but it has had -one unfortunate result: incompatible \LaTeX{} formats came into use at -different sites. Thus, to process documents from various places, a -site maintainer was forced to keep \LaTeX{} (with and without \NFSS), -\SLiTeX, \AmSLaTeX, and so on. In addition, when looking at a source -file it was not always clear for which format the document was written. - -To put an end to this unsatisfactory -situation a new release of \LaTeX{} was produced. -It brings all such extensions back under a single format and thus -prevents the proliferation of mutually incompatible dialects of -\LaTeX~2.09. The new release was available for several months as a -test version, and the final release of 1~June officially -replaces the old version. - -\section{Processing documents with \LaTeXe} - -Documents written for \LaTeX~2.09 will -still be read by \LaTeXe. Any such document is run in -\emph{\LaTeX~2.09 compatibility mode}. - -Unfortunately, compatibility mode comes with a price: it can run -up to 50\% slower than \LaTeX~2.09 did. If you want to run your document -in the faster \emph{native mode}, you should try replacing the line: -\begin{verbatim} - \documentstyle[<options>,<packages>]{<class>} -\end{verbatim} -with: -\begin{verbatim} - \documentclass[<options>]{<class>} - \usepackage{latexsym,<packages>} -\end{verbatim} -Unfortunately, this will not always work, because some \LaTeX~2.09 -packages will only work in \LaTeXe{} compatibility mode. You should find -out if there is a \LaTeXe{} version of the package available. - -\LaTeXe{} native mode also gives access to the new features of \LaTeXe, -described in \emph{\LaTeXe{} for authors}. - -\section{New packages} - -\LaTeXe{} has much better support for graphics, colour, fonts, and -multi-lingual typesetting.

Reading documents containing text like -\verb|na\"\i ve| is frustrating, especially if your keyboard allows -you to type \texttt{na\"\i ve}. - -In the past, \LaTeX{} has not supported input containing accented -characters such as \texttt{\"\i}, because Windows, Macintosh and Unix -all have different ways of dealing with accented input, called -\emph{input encodings}. - -However, the \verb|inputenc| package allows you to specify which input -encoding your document is written with, for example to use the ISO -Latin-1 encoding, you type: -\begin{verbatim} - \usepackage[latin1]{inputenc} -\end{verbatim} -At the moment, \verb|inputenc| supports the \verb|ascii| and -\verb|latin1| input encodings, but more will be added with future -releases. - -The \verb|inputenc| package is -currently a test release. The user interface for the full release will -be upwardly compatible with the test version. - -\section{AMS-\LaTeX{}} - - AMS-\LaTeX{} is a set of miscellaneous extensions for \LaTeX{} - distributed by the American Mathematical Society. They provide superior - information structure and superior printed output for mathematical - documents. - - There are far too many features of AMS-\LaTeX{} to list here. - AMS-\LaTeX{} is described in the accompanying documentation, - and in \emph{The \LaTeX{} Companion}. - - Version 1.2beta of AMS-\LaTeX{} was released for testing by intrepid - users in October 1994. The full release of AMS-\LaTeX{}~1.2 is expected - in early January 1995. - - It will be divided into two bundles: - \begin{itemize} - - \item the \verb|amsfonts| packages, which give access to - hundreds of new mathematical symbols, and new math fonts - such as blackboard bold and fraktur. - - \item the \verb|amsmath| packages, which provide finer control over - mathematical typesetting, such as multi-line subscripts, - enhanced theorem and proof environments, - and improved displayed equations, - - \end{itemize} - For compatibility with older documents, an \verb|amstex| package will be - provided. - -\section{\LaTeX{} on the internet} - -\LaTeX{} has its own home page on the World Wide Web, with the URL: -\begin{verbatim} - http://www.tex.ac.uk/CTAN/latex/ -\end{verbatim} -This page describes \LaTeX{} and the \LaTeX3 project, and contains -pointers to other \LaTeX{} resources, such as the user guides, the -\TeX{} Frequently Asked Questions, and the \LaTeX{} bugs database. - -The electronic home of anything \TeX-related is the Comprehensive -\TeX{} Archive Network (CTAN).

We are on schedule -to deliver a release of \LaTeX{} every six months, in December and -June. - -In the last \emph{\LaTeXNews}, we said ``we don't expect so much -activity in the next six months,'' which has turned out not to be -true! - -\section{Additional input encodings} - -In the last release of \LaTeX{} we distributed a test version of the -\texttt{inputenc} package which allows the use of input characters -other than just a--z and A--Z. The package has proved to be robust, -so we are now distributing an expanded version. -The new release comes with a number of input encodings: - -\begin{itemize} -\item \texttt{ascii} the standard encoding, -\item \texttt{latin1} the ISO Western European alphabet, -\item \texttt{latin2} the ISO Eastern European alphabet, -\item \texttt{cp437} the IBM codepage 437, -\item \texttt{cp850} the IBM codepage 850, and -\item \texttt{applemac} the Apple Macintosh encoding. -\end{itemize} -These can be used by specifying an option to the \texttt{inputenc} -package, for example: -\begin{verbatim} - \usepackage[latin1]{inputenc} -\end{verbatim} -The new input encodings are currently being tested, but we don't -expect any major changes. - -\section{\LaTeX\ getting smaller} - -In the past releases of \LaTeXe, the amount of memory \LaTeX{} -requires has increased, but we are pleased to say that this trend has -been reversed. We hope that future releases of \LaTeX{} will continue -to get smaller. - -For example, on this document, the December 1994 release used 52,622 -words of memory, and the June 1995 release uses 51,216 words of -memory, which is a 2.7\% reduction. - -We are currently experimenting with other ways of reducing the size of -\LaTeX. For example, we are experimenting with an option to remove -the \texttt{picture} and \texttt{tabbing} environments from the -\LaTeX{} kernel, and to load them from a file the first time they are -used. This should help \LaTeX{} to run on machines with limited -memory. See \texttt{autoload.txt} for details. - -\section{Distribution and modification} - -One topic of discussion that has kept us busy is the distribution and -modification conditions of \LaTeX. We are committed to keeping -\LaTeX{} as free reliable software, and ensuring that (as far as -possible) \LaTeX{} documents will produce the same results on all -systems. - -The modification conditions are currently under discussion, and we -would like to hear from anyone interested. Please read -\texttt{modguide.tex} for more information. - -\section{AMS-\LaTeX\ full release} - -The AMS-\LaTeX\ packages were still in beta test in the December 1994 -release of \LaTeX, and the full release came out in January 1995. - -AMS-\LaTeX\ is described in the \emph{User's Guide} -(\texttt{amsldoc.tex}) and in \emph{The \LaTeX{} Companion}. - -\section{PostScript fonts} - -There is a new test release of the PSNFSS packages for accessing -PostScript fonts in \LaTeXe. This includes an update to all of the -fonts, to remove many of the underfull and overfull \verb|\hbox| -warnings, and improve the setting of non-English languages. - -The new release of \LaTeX{} removes all of the `hidden' uses of -Computer Modern mathematics. For example, the footnote markers used -to use math mode, so always used Computer Modern digits rather than -ones from the current text font. This has now been fixed. - -\section{Further information} - -For more information on \TeX{} and \LaTeX, get in touch with your local -\TeX{} Users Group, or the international \TeX{} Users Group, -P.~O.~Box~869, Santa~Barbara, CA~93102-0869, USA, Fax:~+1~805~963~8358, -EMail:~tug@tug.org. - -The \LaTeX{} home page is \verb|http://www.tex.ac.uk/ctan/latex/| -and contains links to other WWW resources for \LaTeX. - -\end{document} diff --git a/Master/texmf-dist/source/latex/base/ltnews04.tex b/Master/texmf-dist/source/latex/base/ltnews04.tex deleted file mode 100644 index 15e95999521..00000000000 --- a/Master/texmf-dist/source/latex/base/ltnews04.tex +++ /dev/null @@ -1,143 +0,0 @@ -% \iffalse meta-comment -% -% Copyright 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 -% The LaTeX3 Project and any individual authors listed elsewhere -% in this file. -% -% This file is part of the LaTeX base system. -% ------------------------------------------- -% -% It may be distributed and/or modified under the -% conditions of the LaTeX Project Public License, either version 1.3c -% of this license or (at your option) any later version. -% The latest version of this license is in -% http://www.latex-project.org/lppl.txt -% and version 1.3c or later is part of all distributions of LaTeX -% version 2005/12/01 or later. -% -% This file has the LPPL maintenance status "maintained". -% -% The list of all files belonging to the LaTeX base distribution is -% given in the file `manifest.txt'.

This is due to an improved version of the -docstrip program that has been contributed by Marcin Woli\'nski. -This can write up to 16 files at once. The -previous version could only write one file at a time which meant that -it was very slow when producing many small files from the same source -file as the source needed to be re-read for each file written. - -\section{New T1 encoded fonts} - -This year J\"org Knappen has completed a new release of the `Cork' -(T1) encoded Computer Modern fonts: the dc fonts release 1.2. - -This release of the dc fonts fixes many bugs (including the missing -\verb|?`| (?`) and \verb|!`| (!`) ligatures) and improves the fonts in -many other ways. It is strongly recommended that you upgrade as soon as -possible if currently you are using the old dc fonts, release 1.1 or -earlier. The new fonts are available from the CTAN archives, in -\texttt{tex-archive/fonts/dc}. - -The names of the font files are \emph{different}. This does not affect -\LaTeX\ documents but \emph{does} affect the installation procedure as -it assumes that you have the \emph{new} fonts, and will write suitable -`fd' files for those fonts. If you have not yet upgraded your dc fonts -then, after unpacking the distribution, you \emph{must} -\verb|latex olddc.ins| to produce `fd' files for the old dc fonts. -This must be done \emph{before} the format is made. Running the test -document at \texttt{ltxcheck.tex} the end of the installation will -inform you if the wrong set of `fd' files has been installed. - -Note that this change does not affect the standard `OT1' Computer -Modern fonts that \LaTeX\ uses by default. - -\section{More robust commands} - -The commands \verb|\cite| and \verb|\sqrt| are now robust. - -Although most commands with optional arguments are fragile, as -documented, such commands defined using the second optional argument -of \verb|\newcommand| and its derivatives are now \emph{robust}. - -\section{New Interface to building `extension' classes} - -The mechanism provided by \verb|\DeclareOption|, \verb|\ProcessOptions| -and \verb|\LoadClass| has proved to be a powerful and expressive means -of defining one class in terms of another `base' class. However there -have been some requests to simplify the declaration of the common case -where you want the `base' class to be called with \emph{all} the -options that were specified to the extension class.

A similar -command \verb|\RequirePackageWithOptions| is provided for package use. -More details of this feature are provided in \texttt{clsguide.tex} and -\texttt{ltclass.dtx}. - -\section{More Input Encodings} - -The experimental \texttt{inputenc} package allows a more natural style -of input of accented and other characters. - -Three new input encodings are now supported. -\begin{itemize} -\item \texttt{ansinew} the Windows ansi encoding, - as used in Microsoft Windows 3.x. -\item \texttt{cp437de} a variant of \texttt{cp437}, which uses \ss\ - rather than $\beta$ in the appropriate slot. -\item \texttt{next} the encoding used on Next computers. -\end{itemize} - -\section{Further information} - -For more information on \TeX{} and \LaTeX, get in touch with your local -\TeX{} Users Group, or the international \TeX{} Users Group, -1850 Union Street, \#1637, San Francisco, CA~94123, USA, -Fax:~+1~415~982~8559, -EMail:~tug@tug.org. -The \LaTeX{} home page is \verb|http://www.tex.ac.uk/ctan/latex/| -and contains links to other WWW resources for \LaTeX. - -\end{document} diff --git a/Master/texmf-dist/source/latex/base/ltnews05.tex b/Master/texmf-dist/source/latex/base/ltnews05.tex deleted file mode 100644 index 9416f0e4ed3..00000000000 --- a/Master/texmf-dist/source/latex/base/ltnews05.tex +++ /dev/null @@ -1,158 +0,0 @@ -% \iffalse meta-comment -% -% Copyright 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 -% The LaTeX3 Project and any individual authors listed elsewhere -% in this file. -% -% This file is part of the LaTeX base system. -% ------------------------------------------- -% -% It may be distributed and/or modified under the -% conditions of the LaTeX Project Public License, either version 1.3c -% of this license or (at your option) any later version. -% The latest version of this license is in -% http://www.latex-project.org/lppl.txt -% and version 1.3c or later is part of all distributions of LaTeX -% version 2005/12/01 or later. -% -% This file has the LPPL maintenance status "maintained". -% -% The list of all files belonging to the LaTeX base distribution is -% given in the file `manifest.txt'.

Previously this option only affected -\verb|\chapter| and \verb|\backmatter|. It now also affects -\verb|\part|, \verb|\frontmatter| and \verb|\mainmatter|. - -\section{More font (output) encodings} -The font encoding name \texttt{T3} has been allocated to the encoding -used in the new 256-character \textsc{IPA} fonts (for the phonetic -alphabet) produced by Rei Fukui. His package, \textsf{tipa}, -gives access to these fonts and should soon be available. (The -encoding named \texttt{OT3} is the 128-character encoding used in the -\textsc{IPA} fonts produced by Washington State University.) - - - -\section{More input encodings supported} -The \textsf{inputenc} package now supports the IBM codepage~852 used -in Eastern Europe, with the option~\texttt{[cp852]} contributed by -Petr~Sojka. - -Also, the \textsf{inputenc} package now activates most `control codes' -with \textsc{ascii} values below 32. -Currently none of the encodings in the standard distribution makes use -of these positions. - -\section{Fixes and improvements} -The \LaTeX\ kernel has only had minor changes, apart from -\verb|\@startsection| mentioned above. -However, some small fixes have been incorporated removing the -following problems: - -\begin{itemize} -\item - In tabular and array, previous versions of \LaTeX\ `lost' the - inter-column space from an `\texttt{l}'-column, when that column - was completely empty. - -\item - Previously, the use of the \verb|\nofiles| command could change - the \emph{vertical spacing} in a document.\\ A side effect of fixing - this is that when \verb|\nofiles| is used, \verb|\label| puts a - blank line in the log file. - -\item - \LaTeX~often loads fonts `on demand'. Previously, this could - happen inside the argument of an accent command and this would - cause the accent to appear in the wrong place. - -\end{itemize} - -\section{Changes to the `tools' packages} - -\begin{itemize} -\item - The \textsf{longtable} package now uses a modified algorithm, - contributed by David Kastrup, to align the `chunks' of a table. - It is now unnecessary to edit the document to add - \verb|\setlongtables| before the final run of \LaTeX. - In certain cases of overlapping \verb|\multicolumn| entries, the new - algorithm will produce better column widths than the old (at the - price of extra passes through \LaTeX). - -\item - The \textsf{dcolumn} package now has the extra possibility of - specifying the number of digits both \emph{before} and after the - `decimal point'. This makes it easy to centre the column of numbers - under a wide heading. -\end{itemize} - -\section{New copy of the \LaTeX\ bug database} -\verb|http://www.tex.ac.uk/ctan/latex/bugs.html| will soon have links -to a copy of the searchable \LaTeX\ bugs database at Mainz (Germany) -as well as the original copy at Sussex (England). - -\end{document} diff --git a/Master/texmf-dist/source/latex/base/ltnews06.tex b/Master/texmf-dist/source/latex/base/ltnews06.tex deleted file mode 100644 index b5c7a28a245..00000000000 --- a/Master/texmf-dist/source/latex/base/ltnews06.tex +++ /dev/null @@ -1,149 +0,0 @@ -% \iffalse meta-comment -% -% Copyright 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 -% The LaTeX3 Project and any individual authors listed elsewhere -% in this file. -% -% This file is part of the LaTeX base system. -% ------------------------------------------- -% -% It may be distributed and/or modified under the -% conditions of the LaTeX Project Public License, either version 1.3c -% of this license or (at your option) any later version. -% The latest version of this license is in -% http://www.latex-project.org/lppl.txt -% and version 1.3c or later is part of all distributions of LaTeX -% version 2005/12/01 or later. -% -% This file has the LPPL maintenance status "maintained". -% -% The list of all files belonging to the LaTeX base distribution is -% given in the file `manifest.txt'.

The \LaTeX\ support -was developed by Mariusz Olko. -\item [TS1] This is the `Text Companion Encoding'; it contains symbols -designed to be used in text, as opposed to mathematical formulas, and -some accents designed for uppercase letters. It is currently -supported by the `tc' fonts, which match the T1 encoded `ec' text -fonts. A subset of the glyphs in this encoding is supported by -virtual fonts distributed with the PostScript font metrics on the -\textsc{ctan} archives. (This is the `8c' encoding in Karl Berry's -fontname scheme.) The \textsf{textcomp} package provides access to -this encoding but here is a warning to current users of that package: -some of the internal names for the characters have changed. -\end{description} - - -\section{New input encodings} - -These additions to the \textsf{inputenc} package are -\texttt{decmulti} (the DEC Multinational -Character Set, contributed by M.~Y.~Chartoire) -and \texttt{cp1250} (an MS-Windows encoding for Central and Eastern -Europe, contributed by Marcin Woli\'nski). There is also a -\texttt{cp1252} encoding that is identical to \texttt{ansinew}. - - -\section{Tools} - -The \textsf{calc} package (used in many examples in \emph{The \LaTeX\ -Companion}) has been contributed to this distribution by Kresten Krab -Thorup and Frank Jensen. This is essentially the same as the version -that has been available from the \textsc{ctan} archives for some time, -with one minor change: to use \LaTeX-style error messages. It enables -the use of arithmetic expressions within arguments to standard -\LaTeX{} commands where a length or a counter value is required. For -example: -\begin{verbatim} - \setcounter {page} { \value{page} * 2 + 1 } - \parbox { 3in - ( 2mm + \textwidth / 9 ) } -\end{verbatim} - -There have also been some improvements to several other packages in -this collection. In particular, \textsf{bm} now works correctly with -constructions such as \verb|\bm{f'}| involving \texttt{'} or other -characters which use \TeX's special ``\verb|\mathcode"8000|'' -feature. Also, \textsf{multicol} sets the length \verb|\columnwidth| -to an appropriate value; this enables it to work with classes that -support two-column setting, e.g.,~the AMS classes. - - -\section{Graphics} - -The special \verb|oztex.def| driver file has been removed, and Oz\TeX\ -support has been merged with dvips, following advice from -Andrew Trevorrow about Oz\TeX~3.x. - -The \textsf{keyval} package has had some internal improvements: to -use \LaTeX\ format error messages; and to avoid `\verb|#| doubling'. -This latter change means that the \verb|command| key for the -\textsf{graphicx} version of \verb|\includegraphics| should now be used -with one \verb|#| rather than two. For example, \verb|command = `gunzip #1|. -Fortunately this key is almost never used in practice, so few if any -documents should be affected by this change. - - -\section{\LaTeX3 experimental programming conventions} - -As announced at the \TeX\ Users Group meeting (Summer 1997), a group of -highly experimental packages will soon be released to allow experienced\\ -\TeX\ programmers to experiment with, and comment on, a proposed set -of syntax conventions and basic data-types that might form -the basis for programming large scale projects in \TeX. -They will be located in\\ -this CTAN directory: -\begin{verbatim} - CTAN:macros/latex/packages/expl3 -\end{verbatim} -The documentation of this material is as follows: individual package -files provide outline, draft documentation; there is an article that -gives an overview of the syntax and related concepts; there is a -\texttt{readme.txt} file containing a brief description of the -collection. - -All aspects of these packages are liable, indeed likely, to change. -They should not be used at this stage for anything -that requires a stable system.

We hope that it proved worth waiting for. It -required a major integration of the code from several people and, -independently, the introduction of the LPPL (see \LaTeX{} News~10) plus -several related changes to our internal systems.

These days the system is sufficiently stable -that the original update policy is costing everybody more time than is -now warranted. - -\section{LPPL update} - -Thanks to extensive and valuable input from Matt Swift -(\email{swift@alum.mit.edu}) we now have a clearer and more detailed -form of the \LaTeX{} Project Public Licence. This release contains -both the original version (in \file{lppl-1-0.txt}) and the updated -version, LPPL~1.1. - -\section{The future of Sli\TeX{}} - -We still get a very small trickle of reports about this part of the -system (if you are no longer able to recall \LaTeX~2.09 then you will -know it as the \class{slides} class). We have not classified them (in -our minds at least) as bugs since we have always known that there are -many problems with this class. It is clear to us that the only -sensible action would be to redesign the system completely; in -particular, to remove much of its complexity whose purpose is to -support 10-year-old overlay technology. However, this would take a -lot too much time and would be completely out of proportion to its -current usage. - -We are therefore planning to make the \class{slides} class -unsupported in the sense that any problem related to the use of -invisible fonts is considered to be a feature (The \LaTeXe{} manual by -Leslie Lamport doesn't even describe this part of the class any more). -Of course, if it still has its enthusiasts then we are happy to cede -it to their loving care (somewhat like a preserved steam locomotive, -in some parts of the world). - -\section{Fontenc package peculiarities} - -The \verb=\usepackage= interface normally ensures that a package is -loaded only once. The \pkg{fontenc} package has become an -exception to this rule: it can be loaded several times using different -options, e.g., allowing the user to add a font encoding in the -preamble. This comes at a price for package writers: the low-level -commands (see \file{ltclass.dtx}) used to check if a package was -loaded, and with which options, do not work for the \pkg{fontenc} -package. - -\section{New math font encodings} - -As we announced in \LaTeX{} News~9, a joint working group of the -\TeX{} Users Group and the \LaTeX3 Project has developed a new -\mbox{8-bit} math font encoding for \TeX{}. -The reason why this work is not yet released is because of other -exciting developments in the world of math fonts and math characters. -It is obviously wise to ensure that the encoding work is fully -integrated with the available fonts. - -Those interested are reminded that further information about the Math -Font Group may be found on the World Wide Web at:\\ -\url{http://www.tug.org/twg/mfg/}. - -\section{Tools distribution} - -The \pkg{multicol} package has now got a small but useful extension -which allows you to force a column break where this is really -necessary. This is done with the command \verb=\columnbreak=, which -can be used like \verb=\pagebreak= (e.g.,~within paragraphs) except -that it cannot have an optional argument and thus it always forces a -new column. - -\section{Coming soon} - -Major work on a new class file structure to support flexible -designs is well under way; some of this work will be presented at the -TUG'99 conference in Vancouver, Canada. With a bit of luck much of -this work could be ready for integration into the next release---so -watch this space! - -\end{document} diff --git a/Master/texmf-dist/source/latex/base/ltnews12.tex b/Master/texmf-dist/source/latex/base/ltnews12.tex deleted file mode 100644 index 47609689cea..00000000000 --- a/Master/texmf-dist/source/latex/base/ltnews12.tex +++ /dev/null @@ -1,154 +0,0 @@ -% \iffalse meta-comment -% -% Copyright 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 -% The LaTeX3 Project and any individual authors listed elsewhere -% in this file. -% -% This file is part of the LaTeX base system. -% ------------------------------------------- -% -% It may be distributed and/or modified under the -% conditions of the LaTeX Project Public License, either version 1.3c -% of this license or (at your option) any later version. -% The latest version of this license is in -% http://www.latex-project.org/lppl.txt -% and version 1.3c or later is part of all distributions of LaTeX -% version 2005/12/01 or later. -% -% This file has the LPPL maintenance status "maintained". -% -% The list of all files belonging to the LaTeX base distribution is -% given in the file `manifest.txt'.

It prevents the line -break that is normally allowed\newline -after the following sequence of dashes. - - -\section{Fixing font sizes} - -The new \package{fix-cm} package, by Walter Schmidt, changes the CM font -definition (\texttt{.fd}) files so that similar design sizes are used -in both the \texttt{OT1} and \texttt{T1} encodings. - - -\section{Font encodings} - -A number of options have been added to the \package{textcomp} package, -enabling only available glyphs to be used. -Also, the `NFSS font families' are now divided into five different groups -according to the subset of glyphs each provides from the full -collection of symbols in the TS1 encoding. -Given sufficient information about a font family -\package{textcomp} will use this in order to limit the\newline -typesetting to those glyphs that are available. - -Use of this mechanism has also enhanced \verb|\oldstylenums| -to use the current font if possible. - - -\section{Displaying font tables} - -With the \package{nfssfont} package you can now -specify the font to display by giving its `NFSS classification', -rather than needing to know its external font file's name. -It is also now possible to generate large collections of font -tables in batch mode by providing a suitable input file. - - -\section{New input encodings} - -The \package{inputenc} package has been extended as follows: -\package{macce} input encoding -(Apple Central European), -thanks to Radek Tryc and Marcin Wolinski; \package{cp1257}\newline -for Baltic languages; \package{latin10}, -thanks to Ionel Ciob\^{i}c\u{a}.\newline -The euro symbol has by -now been added to several encodings: -\package{ansinew}, \package{cp1250} -and \package{cp1252} (which also\newline -has another addition), whilst \package{cp858} -adds it to \package{cp850}. - - -\section{Unicode input} - -Partial, experimental support for text files that use the Unicode -encoding form UTF-8 is now provided by the option \package{utf8} for -the \package{inputenc} package. - -The only Unicode text file characters supported by the current version -are those based on the most common inputs for glyphs from the small -collection\newline -of standard \LaTeX{} Latin encodings. - - -\section{And finally \ldots\ pict2e} - -The old, non-functional version of this package has been removed - as there is now a fully working version from Hubert G\"a{\ss}lein - and Rolf Niepraschk. It is described - in \textit{The \LaTeX{} Manual}. - -\end{document} diff --git a/Master/texmf-dist/source/latex/base/ltnews16.tex b/Master/texmf-dist/source/latex/base/ltnews16.tex deleted file mode 100644 index 69e05973a8e..00000000000 --- a/Master/texmf-dist/source/latex/base/ltnews16.tex +++ /dev/null @@ -1,161 +0,0 @@ -% \iffalse meta-comment -% -% Copyright 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 -% The LaTeX3 Project and any individual authors listed elsewhere -% in this file. -% -% This file is part of the LaTeX base system. -% ------------------------------------------- -% -% It may be distributed and/or modified under the -% conditions of the LaTeX Project Public License, either version 1.3c -% of this license or (at your option) any later version. -% The latest version of this license is in -% http://www.latex-project.org/lppl.txt -% and version 1.3c or later is part of all distributions of LaTeX -% version 2005/12/01 or later. -% -% This file has the LPPL maintenance status "maintained". -% -% The list of all files belonging to the LaTeX base distribution is -% given in the file `manifest.txt'.

Although we remain firmly\newline -resolved not to make changes in the base distribution (the kernel) of -Standard \LaTeX{}, there is still much that needs doing to maintain -its reliability and utility and to keep up the necessary level of -communication with users and supporters. Also, as with all advanced -software systems, bugs are still turning up occasionally so %\newline -some fixes are still essential. - -One major impediment to providing adequate service levels in this area -is, of course, the difficulties inherent in obtaining the time and -commitment of skilled minds---hence the appeal above to anyone -interested %\newline -in getting involved. - - -\section{LPPL certification} - -There are still some outstanding diplomatic tasks around the -\LaTeX{} Project Public Licence: these include -e.g.,~getting it `OSF certified' and ensuring that it gains -more support and wider use, even in the FSF world\newline -where it has long been tolerated. - - -\section{Use of \eTeX/pdf\TeX} - -We expect that within the next two years, releases of \LaTeX{} will -change modestly in order to run best under an extended \TeX{} engine -that contains the \eTeX{} primitives, e.g., \eTeX{} or pdf\TeX{}. -The details of this possible upgrade need further work so we are not -making a definite announcement yet. - -Although the current release does not \emph{require} \eTeX{} features, -we certainly recommend using an extended \TeX{}, especially if you -need to debug macros. - - -\section{End of `autoload' support} - -As computer systems generally grow in capacity, requirements change -and so we believe that the \package{autoload} variant of \LaTeX{} is -no longer required. Thus, although the code remains it is no longer -supported. We hope this does not cause any problems. - - -\section{New models, new code} - -In the period 1999--2001 we published many results of our work over -the previous decade on the development of new concepts and models -for automated typesetting based on \TeX{} as the underlying platform. -These can be found at \url{http://www.latex-project.org/papers/} -and -\mbox{\url{http://www.latex-project.org/code/experimental/}}. - -Since then a very large proportion of the The Team's efforts have been -diverted to provide the core author team for TLC2, which provides -over 1000 pages of carefully researched and tested documentation of -many aspects of the vast world of \LaTeX{} related software that -was developed over that same time period and that continues -to grow and improve prodigiously. - -Completion of that task \ldots\ until TLC3!! \ldots\ presents the -possibility of getting back to this more exciting development work, -or even to more radical work on non-\TeX{}-based models and -implementations. - -Of course, any such ideas are predicated on our ability to organise -(with you, we hope) an efficient\newline -but responsive maintenance and support system\newline -for Standard \LaTeX{}. - -\end{document} diff --git a/Master/texmf-dist/source/latex/base/ltnews17.tex b/Master/texmf-dist/source/latex/base/ltnews17.tex deleted file mode 100644 index 99267429bc4..00000000000 --- a/Master/texmf-dist/source/latex/base/ltnews17.tex +++ /dev/null @@ -1,230 +0,0 @@ -% \iffalse meta-comment -% -% Copyright 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 -% The LaTeX3 Project and any individual authors listed elsewhere -% in this file. -% -% This file is part of the LaTeX base system. -% ------------------------------------------- -% -% It may be distributed and/or modified under the -% conditions of the LaTeX Project Public License, either version 1.3c -% of this license or (at your option) any later version. -% The latest version of this license is in -% http://www.latex-project.org/lppl.txt -% and version 1.3c or later is part of all distributions of LaTeX -% version 2005/12/01 or later. -% -% This file has the LPPL maintenance status "maintained". -% -% The list of all files belonging to the LaTeX base distribution is -% given in the file `manifest.txt'.

In the warranty section the -phrase ``unless required by applicable law'' has been reinstated, -having got lost at some point. Also, -it now contains three clarifications: of the difference between -``maintained'' and ``author-maintained''; of the -term ``Base Interpreter''; and when clause 6b and 6d shall not apply. - -Following requests, we now also provide the text of the licence as a -\LaTeX{} document (in the file \texttt{lppl.tex}). This file can be -processed either as a stand-alone document or it can be included -(without any modification) into another \LaTeX{} document, e.g., as an -appendix, using \verb|\input| or \verb|\include|. - - -\section{New guide on font encodings} - -Way back in 1995 work was started on a guide to document the -officially allocated \LaTeX{} font encoding names. However, for one -reason or another this guide (named \textit{\LaTeX{} font encodings}) -was, until now, not added to the distribution. It describes the major -7-bit and 8-bit font encodings used in the \LaTeX{} world and explains -the restrictions required of conforming text font encodings. It also -lists all the `encoding specific commands' (the LICR or \LaTeX{} -Internal Character Representation) for characters supported by the -encodings \texttt{OT1} and \texttt{T1}. - -When the file \texttt{encguide.tex} is processed by \LaTeX{}, it will -attempt to typeset an encoding table for each encoding it describes. -For this to be possible, \LaTeX{} must be able to find \texttt{.tfm} -files for a representative example font for each encoding. If -\LaTeX{} cannot find such a file then a warning is issued and the -corresponding table is omitted. - - -\section{Robust commands in math} - -The font changing commands in text-mode have been robust commands for years, -but the same has not been true for the math versions such as -\verb|\mathbf|. While the math-mode commands worked correctly in -section heads, they could cause problems in other places such as index -entries. With this release, these math-mode commands are now robust in -the same way as their text-mode counterparts. - -%% -\pagebreak -%% - - -\section{Updates of required packages} - -Several of the packages in the \package{tools} bundle have been updated -for this release. - -The \package{xspace} package has some new features. One is an -interface for adding and removing the exceptions it knows about and -another is that it works with active characters. These remove problems -of incompatibility with the \package{babel} system. - -In \textit{\LaTeX\ News~16} we announced that some packages might -begin to take advantage of \eTeX{} extensions on systems where these -are available: and the latest version of \package{xspace} does just -that. Note also that \package{fixltx2e} will make use of the -facilities in \eTeX{} whenever these are present (see below). - -The \package{calc} package has also been given an update with a few -extra commands. -The commands \verb|\maxof| and \verb|\minof|, each with two -brace-delimited arguments, provide the usual numeric $\max$ and $\min$ -operations. The commands \verb|\settototalheight| and -\verb|\totalheightof| work like \verb|\settoheight| and -\verb|\heightof|. There are also some internal improvements to make -\package{calc} work with some more primitive \TeX\ constructs, such as -\verb|\ifcase|. - -The \package{varioref} package has acquired a few more default -strings but there are still a number of languages for -which good strings are still missing. - -The \package{showkeys} package has also been updated slightly to work -with more recent developments in \package{varioref}. Also, it now -provides an easy way to define the look of the printed labels with -the command \verb|\showkeyslabelformat|. - -\section{Work on \LaTeX{} fixes} - -The package known as \package{fixltx2e} has three new additions. A new -command \verb|\textsubscript| has been added as a complement to the -command \verb|\textsuperscript| in the kernel. Secondly, a new form of -\verb|\DeclareMathSizes| that allows all of its arguments to have a -dimension suffix. This means you can now use expressions such as -\verb|\DeclareMathSizes{9.5dd}{9.5dd}{7.4dd}{6.6dd}|. - -The third new -addition is the robust command \verb|\TextOrMath| which takes two -arguments and executes one of them when typesetting in text or math -mode respectively. This command also takes advantage of \eTeX{} -extensions if available; more specifically, -%% -%%\pagebreak -%% -when the \eTeX{} extensions are available, it does not -destroy kerning between previous letters and the text to be typeset. -The command is also used -internally in \package{fixltx2e} to resolve a problem with -\verb|\fnsymbol|. - -Also, further work has been done on reimplementing -the command \verb|\addpenalty|, which is used internally in several -places: we hope it is an improvement! - -\section{The graphics bundle} - -The \package{graphics} bundle now supports the -\package{dvipdfmx} post-processor and Jonathan Kew's XE\TeX\ -program. By support we mean that the graphics packages recognize the -new options \texttt{xetex} and \texttt{dvipdfmx} but we do not -distribute the respective driver files. - -This leads elegantly to a description of the -new policy concerning such driver files in the \package{graphics} bundle. -Most driver files for our graphics packages are maintained by the -developers of the associated post-processor or \TeX\ programs. -The teams developing these packages are working very hard: their rapid -development offers a stark contrast to the current schedule of \LaTeX\ -releases. It is therefore no longer practical -for the \LaTeX\ Team to be responsible for distributing the -latest versions of these driver files. - -Therefore the installation files for \package{graphics} have been -split: there is now \file{graphics.ins} to install the package files and -\file{graphics-drivers.ins} for the driver files (located in -\file{drivers.dtx}). -There is no need -to install all those provided in the file \file{drivers.dtx}. - -Please also note that, as requested by the maintainers of -\package{PStricks}, we have removed the package \package{pstcol} as -current versions of \package{PSTricks} make it obsolete. - -%% -\newpage -%% - - -\section{Future development} - -The title of this section is a little misleading as it actually -describes \emph{current} development. In 1998 the \package{expl3} -bundle of packages was put on \ctan\ to demonstrate a possible \LaTeX3 -programming environment. These packages have been lying dormant for some -time while the \LaTeX\ Project Team were preoccupied by other things -such as developing the experimental packages \package{xor}, -\package{template}, etc., (and also writing that indispensable -and encyclopaedic volume,\\ -The \LaTeX{} Companion -- 2nd edition). - -In October 2004 work on this code base was resumed with the goal of -some day turning it into a kernel for \LaTeX3. This work can now -also make full use of the widely accepted \eTeX\ extensions. Currently -two areas are central to this work. - -\begin{itemize} -\item Extending the - kernel code of \LaTeX3. -\item Converting the experimental packages - such as \package{xor}, \package{template} to use the new - syntax internally. -\end{itemize} - -Beware! Development of -\package{expl3} is happening so fast that the descriptions above might -be out of date when you read this!

A number of small changes have -been made to correct minor bugs in the kernel, slightly extend the Unicode -support, and improve various -aspects of some of the \texttt{tools} packages. - -\section{New code repository} - -Since the last \LaTeX\ release, the entire code base has been moved -to a public \textsc{svn} repository% -\footnote{\url{http://www.latex-project.org/svnroot/latex2e-public/}} -and the entire build architecture re-written. In fact, it has only -been possible for us to consider a new \LaTeX\ release since earlier -this year when the test suite was finally set up with the new system. -In the process, a bug in the \LaTeX\ picture fonts distributed with -\TeX\ Live was discovered, proving that the -tests are working and are still very valuable. - -Now that we can easily generate new packaged versions of the \LaTeXe\ -distribution, we expect to be able to roll out bug fixes in a much -more timely manner than over the last few years.

This issue is now at least detected and generates an error but the algorithm used by the package is -unable to gracefully handle it in an automated fashion (some alternatives for resolving the problem if it happens are given in the package documentation). - -\paragraph{Improvement in \texttt{xspace} and font-switching} - -The \texttt{xspace} package provides the command \verb|\xspace| -which attempts to be clever about inserting spaces automatically -after user-defined control sequences. -An important bug fix has been made to this command to correct its -behaviour when used in conjunction with font-switching commands -such as \verb|\emph| and \verb|\textbf|. -Previously, writing -\begin{verbatim} - \newcommand\foo{foo\xspace} - ... \emph{\foo} bar baz - ... \emph{\foo}, bar baz -\end{verbatim} -would result in an extraneous space being inserted after `foo' in -both cases; this has now been corrected. - - -\paragraph{RTL in \texttt{multicol}} - - The 1.7 release of \texttt{multicol} adds support for languages that are typeset - right-to-left. For those languages the order of the columns on the page - also needs to be reversed---something that wasn't possible in earlier releases. - -The new feature is supported through the -commands \verb|\RLmulticolcolumns| (switching to right-to-left typesetting) -and \verb|\LRmulticolcolumns| (switching to left-to-right typesetting) the -latter being the default. - -\paragraph{Improve French \texttt{babel} interaction with \texttt{varioref}} - - Extracting and saving the page number turned out to be a source of subtle - bugs. Initially it was done through an \verb"\edef" with a bunch of -\verb"\expandafter" commands inside. This posed a problem if the page number - itself contained code which needed protection (e.g., pr/4080) so this got - changed in the last release to use \verb"\protected@edef". However, that in turn failed with Babel -(bug report/4093) if the label contained active characters, e.g., a ``:'' in French. So now -we use (after one failed attempt pr/4159) even more \verb"\expandafter" commands and \verb"\romannumeral" trickery to avoid any expansion other - than what is absolutely required---making the code in that space absolutely unreadable. -\begin{verbatim} - \expandafter\def\expandafter#1\expandafter{% - \romannumeral - \expandafter\expandafter\expandafter - \z@ - \expandafter \@cdr - \romannumeral - \expandafter\expandafter\expandafter - \z@ - \csname r@#2\endcsname\@nil}% -\end{verbatim} -Code like this nicely demonstrates the limitations in the programming layer of \LaTeXe{} and the advantages that \textsf{expl3} will offer on this level. - -\end{document} diff --git a/Master/texmf-dist/source/latex/base/ltnews21.tex b/Master/texmf-dist/source/latex/base/ltnews21.tex deleted file mode 100644 index b7c87d6f324..00000000000 --- a/Master/texmf-dist/source/latex/base/ltnews21.tex +++ /dev/null @@ -1,255 +0,0 @@ -% \iffalse meta-comment -% -% Copyright 2014 -% The LaTeX3 Project and any individual authors listed elsewhere -% in this file. -% -% This file is part of the LaTeX base system. -% ------------------------------------------- -% -% It may be distributed and/or modified under the -% conditions of the LaTeX Project Public License, either version 1.3c -% of this license or (at your option) any later version. -% The latest version of this license is in -% http://www.latex-project.org/lppl.txt -% and version 1.3c or later is part of all distributions of LaTeX -% version 2005/12/01 or later. -% -% This file has the LPPL maintenance status "maintained". -% -% The list of all files belonging to the LaTeX base distribution is -% given in the file `manifest.txt'.

In addition several packages in the \textsf{base} and -\textsf{required} areas have been updated as detailed below. - - -This has been done in accordance with the philosophy of minimising -problems in both forwards and backwards compatibility, so most of -these changes should not be noticed by the regular \LaTeX\ user. - -References in the text below of the form ``graphics/3873'' are to -bug reports listed -at:\\ \url{http://latex-project.org/cgi-bin/ltxbugs2html} - - -\let\paragraph\subsubsection - -\paragraph{\textsf{fixltx2e} updates} - - - -There are a number of bugs and faulty design decisions in \LaTeXe{} -that should have been corrected long ago in the kernel code. However, -such corrections cannot be done as this would break backwards -compatibility in the following sense. A large number of documents -exist by now that have worked around the bug or have even made use of -a particular misfeature. Thus changing the kernel code would break -too many existing documents. - -The corrections for these types of bug have therefore been collected together -in a package that can be loaded only when needed; its name is \textsf{fixltx2e}. -For this release we made the following changes to this package: -\begin{itemize} -\item - Misspelled float placement specifiers such as - \verb=\begin{figure}[tv]= instead of \texttt{tb} are silently - ignored by the kernel code. Now we test for such letters and issue - an error message. -\item - \LaTeX's float handling algorithm can get out of sync if you mix - single and double-column floats (as they are placed independently - of each other). This was corrected in \textsf{fixltx2e} a few years ago - but the fix was not perfect as one situation using - \verb=\enlargethispage= generated a low-level \TeX{} error. - This behaviour of the package is now improved. -\end{itemize} - - - - -\paragraph{New \textsf{fltrace} package} - -For years the file \texttt{ltoutput.dtx} contained some hidden code to -trace the detailed behaviour of the float placement algorithm of -\LaTeX. Prompted by questions on StackExchange we now extract this -code into a new \textsf{fltrace} package. To see the float algorithm -in action (or to understand why it decides to place all your floats at -the very end of the document) use -\begin{verbatim} - \usepackage{fltrace} \tracefloats -\end{verbatim} -To stop tracing somewhere in the document use -\verb=\tracefloatsoff= and to see the current value of various float -parameters use \verb=\tracefloatvals=. As the package is identical to -the kernel code with tracing added, it may or may not work if you load any -other package that manipulates that part of the kernel code. In such a -case your best bet is to load \textsf{fltrace} first. - -\paragraph{\textsf{inputenc} package updates} - -The \textsf{inputenc} package allows different input encodings for -\LaTeX\ documents to be specified including the important -\texttt{utf8} option used to specify the Unicode UTF-8 encoding. A -common mistake in documents has been to also include this option when -using the Unicode-based \TeX\ engines \hologo{LuaTeX} and \hologo{XeTeX} -producing strange errors as these engines natively deal with UTF-8 -characters. - -If a document stored in an 8bit encoding is processed by -\hologo{pdfTeX}, it needs the \textsf{inputenc} package to work -correctly. However, if such a document is processed unchanged by -\hologo{LuaTeX} or \hologo{XeTeX}, then accented characters may -silently get dropped from the output. - -The package has been modified so that if used with \hologo{LuaTeX} or -\hologo{XeTeX}, then it just issues a warning if \texttt{utf8} or -\texttt{ascii} is specified, and stops with an error for any other -encoding requested. - - - -One further improvement has been made to the encoding definition files -(\texttt{.def}) used by \textsf{inputenc}: the catcode of \texttt{@} -is now saved and restored when reading them instead of always using -\verb=\makeatother= inside the files (latex/4192). - - - -\paragraph{The tools directory} - -In the past each of the sub-directories in the ``required'' section of -the \LaTeX{} distribution contained a single \texttt{.ins} file to -generate the code files from the source files. We have now -started to provide individual \texttt{.ins} files for each of those -packages that are likely to require updates outside a major -\LaTeX{} release. - -\paragraph{\textsf{multicol} updates} - -Version 1.8 of \textsf{multicol} implements some improvements/fixes -and one extension. In the past the balancing algorithm enlarged the -column height until it found a solution that satisfied all -constraints. If there were insufficient break points then the final -column height could have been much larger than expected and if that -happened near the end of the page it resulted in the text overflowing -into the bottom margin. This situation is now detected and in that -case a normal page is cut and balancing is resumed on the next -page. Some overflow is still allowed and controlled via the parameter -\verb=\maxbalancingoverflow=. - -The use of \verb=\enlargethispage= is now properly supported within -the environment. Finally a new command \verb=\docolaction= was added -to allow the execution of code depending on the column in which the -command is executed. See the documentation for details. - -Bug fixes: the new version fixes both a color leak that could happen -in certain situations and the problem that \texttt{multicols} could -mess up the positioning of \verb=\marginpar=s that followed the -environment. - - -\paragraph{\textsf{tabularx} updates} - -The restrictions on embedding \verb|\tabularx| \verb|\endtabularx| -into the definition of a new environment have been relaxed -slightly. See the package documentation for details. - -\paragraph{\textsf{showkeys} updates} - -The \textsf{showkeys} package has been updated to fix problems if used -at the start of list items, and to work if brace groups (\verb|{| and -\verb|}|) are used in the optional argument of -\verb|\cite|. (tools/4162, tools/4173) - - -\paragraph{\textsf{color} updates} - -The \verb|\nopagecolor| command suggested by Heiko Oberdiek, -available for some years in the \textsf{pdftex} option, has been -added to the core package as suggested in graphics/3873. Currently -this is supported in the driver files for \textsf{dvips} and -\textsf{pdftex}. Patches to support other drivers are welcome. - - \paragraph{\textsf{graphicx} updates} - -The \textsf{graphicx} version of \verb|\rotatebox| now allows -\verb|\par| (and blank lines) in values, to match the change made -to the \textsf{graphics} version some years ago. See graphics/4296. - - -\paragraph{\textsf{keyval} updates} - -All parsing used in the \textsf{keyval} package has been changed -to allow \verb|\par| (and blank lines) in values. -(A second change, to parsing of brace groups -in a construct such as \texttt{key=\{\{\{value\}\}\}}, was reverted in v1.15.) -See graphics/3446. - - - - -\vfill - -\section{Standard \LaTeX\ (\LaTeXe) and \textsf{expl3}} - -The substantial collection of innovative code in \textsf{expl3} -implements a new programming language that has for a while now been -used by some writers of \LaTeXe\ packages. This code has recently -also been made available for use on top of plain \TeX\ or {\ConTeXt}, -largely to support generic packages that are supposed to work with -different flavours of \TeX. These uses in no way affect authors of -\LaTeX\ documents and such \LaTeXe\ packages will continue to work as -advertised by their authors with standard \LaTeX. - -This code base will also become an important foundation for the kernel -of \LaTeX3 and so the new programming language can be described as -`The \LaTeX3 Programming Language'.

This -kept the kernel stable, but at the expense of meaning that most users did not -benefit from bug fixes, and that some compromises -which were made to save space in the -machines of the time are still affecting most users today. - -In this release we have started a new update policy. All the fixes previously -available via \textsf{fixltx2e} are now enabled \emph{by default} in the -format, as are some further extensions for extended \TeX\ engines, \eTeX, -\hologo{XeTeX} and \hologo{LuaTeX}. Compatibility and stability are still -important considerations, and while most users will not notice these -improvements, or will want to benefit from them, a new \textsf{latexrelease} -package is provided that will revert all the changes and re-instate the -definitions from earlier releases. The package can also be used with older -releases to effectively \emph{update} the kernel to be equivalent to this 2015 -release. - -A new document, \textsf{latexchanges}, is distributed with the release -that documents all the changes to documented commands since the 2014 -\LaTeX\ release, and will be updated in future releases if further -changes have been made. - -\subsection{The \textsf{latexrelease} package} - -As noted above a new package is available to manage differences between \LaTeX\ -releases. If you wish to revert all changes back to the definitions as they -were in previous releases you may start your document requesting the \LaTeX{} release from May~2014: -\begin{verbatim} -\RequirePackage[2014/05/01]{latexrelease} -\documentclass{article} -\end{verbatim} -Conversely if you start a large project now and want to protect yourself -against possible future changes, you may start your document -\begin{verbatim} -\RequirePackage[2015/01/01]{latexrelease} -\documentclass{article} -\end{verbatim} -Then the version of \textsf{latexrelease} distributed with any future \LaTeX\ -release will revert any changes made in that format, and revert to the -definitions as they where at the beginning of 2015. - -If you wish to share a document using the latest features with a -user restricted to using an older -format, you may use the form above and make the \textsf{latexrelease} package -available on the older installation. The package will then update the format -definitions as needed to enable the older format to work as if dated on the date -specified in the package option. - -\subsection{The \cs{IncludeInRelease} command} - -The mechanism used in the \textsf{latexrelease} package is available for use in -package code. If in your \textsf{zzz} package you have -\begin{verbatim} -\RequirePackage{latexrelease} -\IncludeInRelease{2015/06/01} - {\zzz}{\zzz definition} - \def\zzz......new code -\EndIncludeInRelease -\IncludeInRelease{0000/00/00} - {\zzz}{\zzz definition} - \def\zzz....original -\EndIncludeInRelease -\end{verbatim} -then in a document using a format dated 2015/06/01 or later, the ``new code'' -will be used, and for documents being processed with an older format, the -``original'' code will be used. Note the format date here may be the original -format date as shown at the start of every \LaTeX\ run, or a format date -specified as a package option to the \textsf{latexrelease} package. - -So if the document has -\begin{verbatim} -\RequirePackage[2014/05/01]{latexrelease} -\documentclass{article} -\usepackage{zzz} -\end{verbatim} -then it will use the \emph{original} definition of \verb|\zzz| even if -processed with the current format, as the format acts as if dated 2014/05/01. - - -\subsection{Limitations of the approach} - -The new concept provides full backward and forward compatibility for -the \LaTeX{} format, i.e., with the help of a current -\textsf{latexrelease} package the kernel can emulate all released -formats (starting with 2014/06/01\footnote{Patching an older format - most likely works too, given that the changes in the past have been - minimal, though this isn't guaranteed and hasn't been tested.}). - - -However, this is not necessarily true for all packages. - Only if a package makes use of the \cs{IncludeInRelease} -functionality will it adjust to the -requested \LaTeX{} release date. Initially this will only be true for -a few selected packages and in general it may not even be advisable for packages -that have their own well-established release cycles and methods. - -Thus, to regenerate a document with 100\,\% compatible behavior -it will still be necessary -to archive it together with all its inputs, for example, by archiving -the base distribution trees (and any modifications made). However, the -fact that a document requests a specific \LaTeX{} release date should -help identifying what release tree to use to achieve perfect accuracy. - - -\section{Updates to the kernel} - -\subsection{Updates incorporated from \textsf{fixltx2e}} - -The detailed list of changes incorporated from \textsf{fixltx2e} is -available in the new \textsf{latexchanges} document that is -distributed with this release. The main changes are that $2$-column -floats are kept in sequence with one column floats, corrections are -made to the \verb|\mark| system to ensure correct page headings in -$2$-column documents, several additional commands are made robust. - -\subsection{\eTeX\ register allocation} - -\LaTeX\ has traditionally used allocation routines inherited from plain \TeX\ -that allocated registers in the range $0$--$255$. Almost all distributions have -for some years used \eTeX\ based formats (or \hologo{XeTeX} or \hologo{LuaTeX}) -which have $2^{15}$ registers of each type ($2^{16}$ in the case of -\hologo{LuaTeX}). The \textsf{etex} package has been available to provided an -allocation mechanism for these extended registers but now the format will by -default allocate in a range suitable for the engine being used. The new -allocation mechanism is different than the \textsf{etex} package mechanism, and -supports \hologo{LuaTeX}'s full range and an allocation mechanism for \LaTeX\ -floats as described below. - -On \eTeX\ based engines, an additional command, \verb|\newmarks| is available -(as with the \textsf{etex} package) that allocates extended \eTeX\ marks, and -similarly if \hologo{XeTeX} is detected a new command -\verb|\newXeTeXintercharclass| is available, this is similar to the command -previously defined in the \texttt{xelatex.ini} file used to build the -\texttt{xelatex} format. - -\subsection{Additional \LaTeX{} float storage} - -\LaTeX's float placement algorithm needs to store floats (figures and tables) -until it finds a suitable page to output them. It allocates $18$ registers for -this storage, but this can often be insufficient. - The contributed \textsf{morefloats} package has -been available to extend this list; however, it also only allocates from the -standard range $0$--$255$ so cannot take advantage of the extended registers. -The new allocation mechanism in this release incorporates a new command -\verb|\extrafloats|. If you get the error: -\mbox{\texttt{Too many unprocessed floats.}} -then you can add (say) \verb|\extrafloats{500}| to the document preamble to -make many more boxes available to hold floats. - - -\subsection{Built-in support for Unicode engines} - -The kernel sources now detect the engine being used and adjust definitions -accordingly, this reduces the need for the ``\texttt{.ini}'' files used to make -the formats to patch definitions defined in \texttt{latex.ltx}. - -As noted above the format now includes extended allocation routines. - -The distribution includes a file \textsf{unicode-letters.def} derived from the -Unicode Consortium's Unicode Character Data files that details the upper and -lower case transformation data for the full Unicode range. This is used to set -the \verb|lccode| and \verb|uccode| values if a Unicode engine is being used, -rather than the values derived from the T1 font encoding which are used with -8-bit engines. - -Finally \verb|\typein| is modified if \hologo{LuaTeX} is detected -such that it works with this engine. - -\section{l3build} - -This release has been tested and built using a new build system implemented in -\textsf{Lua}, intended to be run on the \textsf{texlua} interpreter distributed -with modern \TeX\ distributions. It is already separately available -from CTAN. This replaces earlier build systems (based at various times on -\textsf{make}, \textsf{cons}, and Windows \textsf{bat} files). It allows the -sources to be tested and packaged on a range of platforms (within the team, -OS X, Windows, Linux and Cygwin platforms are used). It also allows the -format to be tested on \hologo{XeTeX} and \hologo{LuaTeX} as well as the -standard \hologo{pdfTeX}/\eTeX\ engines. - -\section{Hyperlinked documentation and TDS zip files} - -As well as updating the build system, the team have looked again at exactly -what gets released to \textsc{ctan}. Taking inspiration from Heiko Oberdiek's -\textsf{latex-tds} bundle, the PDF documentation provided now includes -hyperlinks where appropriate. This has been done without modifying the sources -such that users without \textsf{hyperref} available can still typeset the -documentation using only the core distribution. At the same time, the release -now includes ready-to-install TDS-style zip files. This will be of principal -interest to \TeX\ system maintainers, but end users with older machines who -wish to manually update \LaTeX\ will also benefit. - -\end{document} diff --git a/Master/texmf-dist/source/latex/base/ltnews23.tex b/Master/texmf-dist/source/latex/base/ltnews23.tex deleted file mode 100644 index 149bd1a74bb..00000000000 --- a/Master/texmf-dist/source/latex/base/ltnews23.tex +++ /dev/null @@ -1,257 +0,0 @@ -% \iffalse meta-comment -% -% Copyright 2015 -% The LaTeX3 Project and any individual authors listed elsewhere -% in this file. -% -% This file is part of the LaTeX base system. -% ------------------------------------------- -% -% It may be distributed and/or modified under the -% conditions of the LaTeX Project Public License, either version 1.3c -% of this license or (at your option) any later version. -% The latest version of this license is in -% http://www.latex-project.org/lppl.txt -% and version 1.3c or later is part of all distributions of LaTeX -% version 2005/12/01 or later. -% -% This file has the LPPL maintenance status "maintained". -% -% The list of all files belonging to the LaTeX base distribution is -% given in the file `manifest.txt'.

However, just as -noted with the \package{etex} package in the previous release, it is -better if allocation is handled by the format to avoid problems with -conflicts between different allocation schemes, or definitions made -before a package-defined allocation scheme is enabled. - -The facilities incorporated into the format with this release, and -described below, are closely modelled on the \package{luatexbase} -package and we thank the authors, and especially \'{E}lie Roux, for -help in arranging this transition. - -The implementation of these \hologo{LuaTeX} features has been -redesigned to match the allocation system introduced in the 2015/01/01 -\LaTeX\ release, and there are some other differences from the previous -\package{luatexbase} package. However, as noted below, -\package{luatexbase} is being updated in line with this \LaTeX\ release -to provide the previous interface as a wrapper around the new -implementation, so we expect the majority of documents using -\package{luatexbase} to work without change. - -\subsection{Names of \hologo{LuaTeX} primitive commands} - -The 2015/01/01 \LaTeX\ release for the first time initialised -\hologo{LuaTeX} in \textsf{latex.ltx} if \hologo{LuaTeX} is being -used. Following the convention used in the contributed -\textsf{lualatex.ini} file used to set up the format for earlier -releases, most \hologo{LuaTeX}-specific primitives were defined with -names prefixed by \texttt{luatex}. This was designed to minimize name -clashes but had the disadvantage that names did not match the -\hologo{LuaTeX} manual, or the names used in other formats, and -produced some awkward command names such as \verb|\luatexluafunction|. -From this release the names are enabled without the \texttt{luatex} -prefix. - -In practice this change should not affect many documents; relatively -few packages access the primitive commands, and many of those are -already set up to work with prefixed or unprefixed names, so that they -work with multiple formats. - -For package writers, if you want to ensure that your code works with -this and earlier releases, use unprefixed names in the package and -ensure that they are defined by using code such as: -\begin{verbatim} -\directlua{tex.enableprimitives("", - tex.extraprimitives( - "omega", "aleph", "luatex"))} -\end{verbatim} -Conversely if your document uses a package relying on prefixed names -then you can add: -\begin{verbatim} -\directlua{tex.enableprimitives("luatex", - tex.extraprimitives( - "omega", "aleph", "luatex"))} -\end{verbatim} -to your document. - -Note the compatibility layer offered by the \package{luatexbase} package -described below makes several commands available under both names. - -As always, this change can be reverted using:\\ -\verb|\RequirePackage[2015/01/01]{latexrelease}|\\ -at the start of the document. - - - -\subsection{\TeX\ commands for allocation in \hologo{LuaTeX}} -For detailed descriptions of the new allocation commands see the -documented sources in \textsf{ltluatex.dtx} or chapter N of -\textsf{source2e}; however, the following new allocation commands are -defined by default in \hologo{LuaTeX}: -\verb|\newattribute|, -\verb|\newcatcodetable|, -\verb|\newluafunction| and -\verb|\newwhatsit|. -In addition, the commands \verb|\setattribute| and -\verb|\unsetattribute| are defined to set and unset Lua attributes -(integer values similar to counters, but attached to nodes). Finally -several catcode tables are predefined: -\verb|\catcodetable@initex|, -\verb|\catcodetable@string|, -\verb|\catcodetable@latex|, -\verb|\catcodetable@atletter|. - -\subsection{Predefined Lua functions} -If used with \hologo{LuaTeX}, \LaTeX\ will initialise a Lua table, -\textsf{luatexbase}, with functions supporting allocation and also -the registering of Lua callback functions. - -\subsection{Support for older releases and plain \TeX} -The \hologo{LuaTeX} allocation functionality made available in this -release is also available in plain \TeX\ and older \LaTeX\ releases -in the files \textsf{ltluatex.tex} and \textsf{ltluatex.lua} which may be -used simply by including the \TeX\ file: \verb|\input{ltluatex}|. -An alternative for old \LaTeX\ releases is to use:\\ -\verb|\RequirePackage[2015/10/01]{latexrelease}|\\ -which will update the kernel to the current release, including -\hologo{LuaTeX} support. - -\subsection{Additional \hologo{LuaTeX} support packages} -In addition to the base \LaTeX\ release two packages have been -contributed to the \textsf{contrib} area on CTAN. The -\package{ctablestack} package offers some commands to help package -writers control the \hologo{LuaTeX} \textsf{catcodetable} -functionality, and the \package{luatexbase} package replaces the -previously available package of the same name, providing a compatible -interface but implemented over the \package{ltluatex} code. - -\section{More Floats and Inserts} -If \hologo{eTeX} is available, the number of registers allocated in -the format to hold floats such as figures is increased from 18 to 52. - -The extended allocation system introduced in 2015/01/01 means that in -most cases it is no longer necessary to load the \package{etex} -package. Many classes and packages that previously loaded this package -no longer do so. Unfortunately in some circumstances where a package -or class previously used the \package{etex} \verb|\reserveinserts| -command, it is possible for a document that previously worked to -generate an error ``no room for a new insert''. In practice this error -can always be avoided by declaring inserts earlier, before the -registers below 256 are all allocated. However, it is better not -to require packages to be re-ordered and in some cases the re-ordering -is complicated due to delayed allocations in \verb|\AtBeginDocument|. - -In this release, a new implementation of -\verb|\newinsert| is used which allocates inserts from the previously -allocated float lists once the classical register allocation has run -out. This allows an extra 52 (or in \hologo{LuaTeX}, 64~thousand) -insert allocations which is more than enough for practical documents -(by default, \LaTeX\ only uses two insert allocations). - -\section{Updated Unicode data} - - -The file \textsf{unicode-letters.def} recording catcodes, upper and -lower case mappings and other properties for Unicode characters has -been regenerated using the data files from Unicode~8.0.0. - -\section{Support for Comma Accent} -The command \verb|\textcommabelow| has been added to the format. -This is mainly used for the Romanian letters -\textcommabelow{S}\textcommabelow{s}\textcommabelow{T}\textcommabelow{t}. -This was requested in latex/4414 in the \LaTeX\ bug tracker. - -\section{Extended \package{inputenc}} -The \texttt{utf8} option for \package{inputenc} has been extended to support -the letters s and t with comma accent, -U+0218\,--\,U+021b. Similarly circumflex w and y U+0174\,--\,U+0177 are defined. -Also U+00a0 and U+00ad are declared by default, and defined to be -\verb|\nobreakspace| and \verb|\-| respectively. - -The error message given on undefined UTF-8 input characters -now displays the Unicode number -in U+\textit{hex} format in addition -to showing the character. - -\section{Pre-release Releases} -The patch level mechanism has been used previously to identify \LaTeX\ -releases that have small patches applied to the main release, without -changing the main format date. - -The mechanism has now been extended to allow identification of -pre-release versions of the software (which may or may not be released -via CTAN) but can be identified with a banner such as\\ -{\catcode`\<=13 \def<{\string<} \catcode`\>=13 \def>{\string>}% -\verb|LaTeX2e <2015/10/01> pre-release-1|}\\ -Internally this is identified as a patch release with a negative patch -level. - -\section{Updates in tools} - -The \package{multicol} package has been updated to fix the interaction -with ``here'' floats that land on the same page as the start or end of -a \textsf{multicols} environment. - -\end{document} diff --git a/Master/texmf-dist/source/latex/base/ltnews24.tex b/Master/texmf-dist/source/latex/base/ltnews24.tex deleted file mode 100644 index 573f1e87c87..00000000000 --- a/Master/texmf-dist/source/latex/base/ltnews24.tex +++ /dev/null @@ -1,263 +0,0 @@ -% \iffalse meta-comment -% -% Copyright 2015,2016 -% The LaTeX3 Project and any individual authors listed elsewhere -% in this file. -% -% This file is part of the LaTeX base system. -% ------------------------------------------- -% -% It may be distributed and/or modified under the -% conditions of the LaTeX Project Public License, either version 1.3c -% of this license or (at your option) any later version. -% The latest version of this license is in -% http://www.latex-project.org/lppl.txt -% and version 1.3c or later is part of all distributions of LaTeX -% version 2005/12/01 or later. -% -% This file has the LPPL maintenance status "maintained". -% -% The list of all files belonging to the LaTeX base distribution is -% given in the file `manifest.txt'.

A number of patches have been added to improve the -behavior of \package{ltluatex} (thanks largely to code review by Philipp Gesang). -The kernel code has been adjusted to -allow for changes in \hologo{LuaTeX} v0.85--v0.88. Most notably, newer -\hologo{LuaTeX} releases allow more than $16$ write streams and these are now -enabled for use by \verb|\newwrite|, but also the experimental -\texttt{newtoken} Lua library has been renamed back to \texttt{token} -which required small adjustments in the \hologo{LuaTeX} setup. - -The biggest change in \hologo{LuaTeX} v0.85--v0.87 compared to previous -versions is that all the primitives (originally defined in -\hologo{pdfTeX}) dealing with the PDF ``back end'' -are no longer defined, being replaced by a much smaller set of new primitives. -This does not directly affect the core \LaTeX{} -files in this release but has required major changes to the -\texttt{.ini} files used by \TeX{} Live and similar distributions to -set up the format files. These changes in the \hologo{LuaTeX} engine -will affect any packages using these back end commands (packages such -as \package{graphics}, \package{color}, \package{hyperref}, etc.). -Until all contributed packages are updated to the new syntax users may -need to add aliases for the old \hologo{pdfTeX} commands. A new -\package{luapdftexalias} package has been contributed to CTAN (not part of the -core \LaTeX\ release) that may be used for this purpose. - -See also the sections below for related changes in the -\textsf{tools} and \textsf{graphics} bundles. - - -\section{Unicode data} - -As noted in \LaTeX{} News~22, the 2015/01/01 release of \LaTeX{} introduced -built-in support for extended \TeX{} systems. In particular, the kernel now -loads appropriate data from the Unicode Consortium to set \verb|\lccode|, -\verb|\uccode|, \verb|\catcode| and \verb|\sfcode| values in an automated -fashion for the entire Unicode range. - -The initial approach taken by the team was to incorporate the existing model -used by (plain) \hologo{XeTeX} and to pre-process the ``raw'' Unicode data into -a ready-to-use form as \verb|unicode-letters.def|. However, the relationship -between the Unicode Consortium files and \TeX{} data structures is non-trivial and still -being explored. As such, it is preferable to directly parse the original -(\verb|.txt|) files at point of use. The team has therefore ``spun-out'' both -the data and the loading to a new generic package, \package{unicode-data}. This -package makes the original Unicode Consortium data files available in the -\verb|texmf| tree (in \verb|tex/generic/unicode-data|) and provides generic -loaders suitable for reading this data into the plain, \LaTeXe{}, and other, -formats. - -At present, the following data files are included in this new package: -\begin{itemize}\parskip=0pt - \item \verb|CaseFolding.txt| - \item \verb|EastAsianWidth.txt| - \item \verb|LineBreak.txt| - \item \verb|MathClass.txt| - \item \verb|SpecialCasing.txt| - \item \verb|UnicodeData.txt| -\end{itemize} -These files are used either by \LaTeXe{} or by \package{expl3} -(i.e.~they represent the set currently required by the team). The -Unicode Consortium provides various other data files and we would be happy to add -these to the generic package, as it is intended to provide a single place -to collect this material in the \verb|texmf| tree. Such requests can be -mailed to the team as~usual or logged at the package home page: -\url{https://github.com/latex3/unicode-data}. - -The new approach extends use of Unicode data in setting \TeX{} information in -two ways. First, the \verb|\sfcode| of all end-of-quotation/closing punctuation -is now set to $0$ (transparent to \TeX{}). Second, \verb|\Umathcode| values are -now set using \verb|MathClass.txt| rather than setting up only letters (which -was done using an arbitrary plane~$0$/plane~$1$ separation). There are also -minor refinements to the existing code setting, particularly splitting the -concepts of case and letter/non-letter category codes. - -For \hologo{XeTeX}, users should note that \verb|\xtxHanGlue| and -\verb|\xtxHanSpace| are \emph{no longer defined}, that no assignments are made -to \verb|\XeTeXinterchartoks| and that no \verb|\XeTeXintercharclass| data is -loaded into the format. The values which were previously inherited from -the plain \hologo{XeTeX} setup files are \emph{not} suitable for properly -typesetting East Asian text. There are third-party packages addressing this -area well, notably those in the \package{CTeX} bundle. Third-party packages -may need adjustment to load the data themselves; see the \textsf{unicode-data} -package for one possible loader. - -\section{More support for east European accents} - -As noted in \LaTeX{} News~23, comma accent support was added for \texttt{s} and -\texttt{t} in the 2015/10/01 release. In this release a matching -\verb|\textcommaabove| accent has been added for U+0123 (\verb|\c{g}|, -\textcommaabove{g}) which is the lower case of U+0122 (\verb|\c{G}|, -\textcommabelow{G}). In the OT1 and T1 encodings the combinations are -declared as composites with the \verb|\c| command, which matches the -Unicode names ``\textsf{latin (capital|small) letter g with cedilla}'' and -also allows \verb|\MakeUppercase{\c{g}}| to produce \verb|\c{G}|, as -required. In T1 encoding, the composite of \verb|\c| with \texttt{k}, \texttt{l}, -\texttt{n} and \texttt{r} are also -declared to use the comma below accent rather than cedilla to match the -conventional use of these letters. - -The UTF-8 \texttt{inputenc} option \texttt{utf8} has been extended to -support all latin combinations that can be reasonably constructed with a -(single) accent command an a base character for the T1 encoding so -\textcommaabove{g}, \k{u} and similar characters may be directly input -using UTF-8 encoding. - -\section{Changes in Graphics} - -The changes in \hologo{LuaTeX}~v0.87 mean that the \package{color} and -\package{graphics} packages no longer share the \texttt{pdftex.def} file -between \hologo{LuaTeX} and \hologo{pdfTeX}. A separate file -\texttt{luatex.def} (distributed separately) has been produced, and -distributions are encouraged to modify \texttt{graphics.cfg} and -\texttt{color.cfg} configuration files to default to the \texttt{luatex} -option if \hologo{LuaTeX}~v0.87 or later is being used. The team has -contributed suitable \texttt{.cfg} files to CTAN to be used -as models. - -Normally it is best to let the local \texttt{graphics.cfg} -automatically supply the right option depending on the \TeX\ engine -being used; however the \package{color} and \package{graphics} (and so -\package{graphicx}) packages have been extended to have an explicit -\texttt{luatex} option comparable to the existing \texttt{pdftex} and -\texttt{xetex} options. - -The \package{trig} package has been updated so that pre-computed values -such as $\sin(90)$ now expand to digits (\texttt{1} rather than the -internal token \verb|\@one| in this case). This allows them to be used -directly in PDF literal strings. - -\section{Changes in Tools} - -\hologo{LuaTeX} from version v0.87 no longer supports the -\verb|\write18| syntax to access system commands. A new package -\package{shellesc} has been added to \textsf{tools} that defines a new -command \verb|\ShellEscape| that may be used in all \TeX\ variants to -provide a consistent access to system commands. The package also -defines \verb|\write18| in \hologo{LuaTeX} so that it continues to access -system commands as before; see the package documentation for details. - -\section{Improving support for Unicode engines} - -\looseness=-1 -Stability concerns are always paramount when considering any change to -the \LaTeXe{} kernel. At the same time, it is important that the format -remains usable and gives reliable results for users. For the Unicode -\TeX{} engines \hologo{XeTeX} and \hologo{LuaTeX} there are important -differences in behavior from classical ($8$-bit) \TeX{} engines which -mean that identical default behaviors are not appropriate. Over the -past 18 months the team has addressed the most pressing of these -considerations (as detailed above and in \LaTeX{} News~22 and 23), -primarily by integrating existing patches into the kernel. There are, -though, important areas which still need consideration, and which -\emph{may} result in refinements to kernel support in this area in -future releases. - -The default font setup in \LaTeXe{} at present is to use the \texttt{OT1} -encoding. This assumes that hyphenation patterns have been read using -appropriate codes: the \texttt{T1} encoding is assumed. The commonly-used -hyphenation patterns today, \package{hyph-utf8}, are set up in this -way for $8$-bit engines (\hologo{pdfTeX}) but for Unicode engines use -Unicode code points. This means that hyphenation will be incorrect -with Unicode engines unless a Unicode font is loaded. This requires -a concept of a Unicode font encoding, which is currently provided by -the \package{fontspec} package in two versions, \texttt{EU1} and -\texttt{EU2}. The team is working to fully understand what is meant -by a ``Unicode font encoding'', as unlike a classical \TeX{} encoding -it is essentially impossible to know what glyphs will be provided -(though each slot is always defined with the same meaning). There -is also an overlap between this area and ideas of language and writing -system, most obviously in documents featuring mixed scripts (for example -Latin and Cyrillic). - -As well as these font considerations, the team is also exploring -to what extent it is possible to allow existing ($8$-bit) -documents to compile directly with Unicode engines without requiring -changes in the sources. Whether this is truly possible remains an open -question. - -It is important to stress that changes will only be made in this area where -they do \emph{not} affect documents processed with -\hologo{eTeX}/\hologo{pdfTeX} (i.e.~documents which are written for -``classical'' $8$-bit \TeX{} engines). Changes will also be made only where -they clearly address deficiencies in the current setup for Unicode engines -(i.e.~where current behaviors are wrong). - -\end{document} diff --git a/Master/texmf-dist/source/latex/base/ltnews25.tex b/Master/texmf-dist/source/latex/base/ltnews25.tex deleted file mode 100644 index e32187e702f..00000000000 --- a/Master/texmf-dist/source/latex/base/ltnews25.tex +++ /dev/null @@ -1,137 +0,0 @@ -% \iffalse meta-comment -% -% Copyright 2016 -% The LaTeX3 Project and any individual authors listed elsewhere -% in this file. -% -% This file is part of the LaTeX base system. -% ------------------------------------------- -% -% It may be distributed and/or modified under the -% conditions of the LaTeX Project Public License, either version 1.3c -% of this license or (at your option) any later version. -% The latest version of this license is in -% http://www.latex-project.org/lppl.txt -% and version 1.3c or later is part of all distributions of LaTeX -% version 2005/12/01 or later. -% -% This file has the LPPL maintenance status "maintained". -% -% The list of all files belonging to the LaTeX base distribution is -% given in the file `manifest.txt'.

For Unicode based \TeX\ engines, this -is not really suitable, and is especially problematic with -\hologo{XeLaTeX} as in the major distributions this is built with -Unicode based hyphenation patterns in the format. In practice this has -not been a major problem as documents use the contributed -\textsf{fontspec} package in order to switch to a -Unicode encoded font. - -In this release we are adding \texttt{TU} as a new supported -encoding in addition to the previously supported encodings such as \texttt{OT1} -and \texttt{T1}. This denotes a Unicode based font encoding. It is essentially -the same as the \texttt{TU} encoding that has been on trial with the -experimental \texttt{tuenc} option to \textsf{fontspec} for the past -year. - -The \hologo{XeLaTeX} and \hologo{LuaLaTeX} formats will now default -to \texttt{TU} encoding and \texttt{lmr} (Latin Modern) family. In the -case of \hologo{LuaLaTeX} the contributed \textsf{luaotfload} Lua -module will be loaded at the start of each run to enable the loading -of OpenType fonts. - -The \textsf{fontspec} package is being adjusted in a companion release -to recognise the new encoding default arrangements. - -Note that in practice no font supports the full Unicode range, and so -\texttt{TU} encoded fonts, unlike fonts specified for \texttt{T1}, may be -expected to be incomplete in various ways. In the current release the file -\texttt{tuenc.def} that implements the \texttt{TU} encoding-specific commands -has made some basic assumptions for (for example) default handling of -accent commands, and the set of command names is derived from the -command names used for the UTF-8 support in the \textsf{inputenc} package, -restricted roughly to the character ranges classically provided by -the \texttt{T1} and \texttt{TS1} encodings, but is part of a longer term plan -seen over recent releases to increase support for Unicode based \TeX\ engines -into the core \LaTeX\ support. - - - -If for any reason you need to process a document with the previous -default \texttt{OT1} encoding, you may switch encoding in the usual ways, for -example -\begin{verbatim} -\usepackage[OT1]{fontenc} -\end{verbatim} -or you may roll back all the changes for this release by starting the -document with -\begin{verbatim} -\RequirePackage[2016/12/31]{latexrelease} -\end{verbatim} - -\section{\cs{showhyphens} in \hologo{XeLaTeX}} -Due to the way \hologo{XeLaTeX} interfaces to font libraries, the -standard definition of \cs{showhyphens} does not work. A variant -definition has been available in the contributed \textsf{xltxtra} -package, however a (slightly different) definition for \cs{showhyphens} -is now included in \hologo{XeLaTeX} by default. As usual -this change will be undone if an earlier -release is specified using the \textsf{latexrelease} package. - -\section{The \textsf{fixltx2e} package} -As described in \LaTeX{} News~22, the \textsf{fixltx2e} package has become -obsolete with the new update policy. Since 2015 it has just made a -warning and exited. In this release we have re-introduced all -the code from the original fixes in the 2014 \LaTeX\ but guarded by -\verb|\IncludeInRelease{2015/01/01}|. -So for current releases \textsf{fixltx2e} still just displays a warning -but for old releases, whether that is an old format, or a format with -the version date reset via the \textsf{latexrelease} package, the -fixes in the original \textsf{fixltx2e} will be applied. - -This improves the ability to run old documents in a way that is compatible -with contemporary formats. If you have a 2014 document that used -\verb|\usepackage{fixltx2e}| and you add -\verb|\RequirePackage[2014/01/01]{latexrelease}| and process it with the -current format then \textsf{latexrelease} will undo most changes made -since 2014, but now when the document includes \textsf{fixltx2e} it -will act like a 2014 version of the package and apply the code fixes, -not just give a warning that the package is obsolete. - -\section{The \textsf{latexbug} package} - -As explained in more detail -at the \LaTeX\ Project - website\footnote{\url{https://www.latex-project.org/bugs/}} -a new package, \textsf{latexbug}, has been produced to help produce -test files to accompany bug reports on the core \LaTeX\ distribution. -This is being published separately to CTAN at the same time as this -release. By using the \textsf{latexbug} package you can easily check -that the packages involved in the test are all part of the core -release. The \LaTeX\ project cannot handle bug reports on contributed -packages, which should be directed to the package maintainer as given -in the package documentation. - -\section{Updates to \textsf{amsmath}} -The \textsf{amsmath} package has two updates at this release. -\begin{itemize} -\item The spacing to the left of the \texttt{aligned} and - \texttt{gathered} environments has been fixed: the spurious thin - space is no longer added by default. Package options control this - to revert to the original behaviour where required; see the - \textsf{amsldoc} guide for further details. -\item The large delimiters around generalised fractions (for example - in the \cs{binom} construct) did not work in previous releases if - using \hologo{LuaTeX} or \hologo{XeTeX} with OpenType math fonts. This is - related to the lack of specific metrics for this use in the OpenType Math - table. In principle \hologo{LuaTeX} has two additional named metrics - to control the delimiters but these are not initialised by default, - and in \hologo{XeTeX} it does not seem possible to make them work at all. - So for Unicode \TeX\ systems, a new implementation of - \cs{genfrac} is used at this release that uses \verb|\left\right| - internally but parameterised to give spacing as close to the - original as possible. The implementation in (pdf)\TeX\ is - unaffected. -\end{itemize} - -\section{Updates to \textsf{tools}} -The \textsf{array} package has been updated to fix a longstanding but -previously unreported issue with unwanted interactions between tables -in the page head or foot and the body of the page, as reported in -\href{http://www.latex-project.org/cgi-bin/ltxbugs2html?pr=tools/4488}{PR - tools/4488}. -There is also an update to the \hologo{LuaTeX} support in \textsf{bm}. - -\section{An addendum to the release changes in 2015: page breaks and vertical spacing} - -In 2015 we announced the introduction of the roll-back\slash -roll-forward concept to manage bug fixes and additions to core -\LaTeX{} in a manageable way. We also announced at that time -that we now incorporate all fixes from \textsf{fixltx2e} into the -kernel (as the old mechanism produced problems instead of improving -the situation). Refer to -\href{https://www.latex-project.org/news/latex2e-news/ltnews22.pdf}{\texttt{ltnews22.pdf}} -for details. - -One of the fixes from \textsf{fixltx2e} was for a glaring bug in -\cs{addvspace} that was originally detected in the mid-nineties and -back then added to the \textsf{fixltx2e} support package. In certain -situations \cs{addvspace} would result in a page/column break below -the baseline of the last line. As a result documents using -\cs{flushbottom} would show a clear misalignment (even more prominent -when typesetting in two-column mode). - -Starting with release 2015/01/01 this is now finally corrected already -in the kernel and not only in \textsf{fixltx2e}. In nearly all -circumstances this will either make no difference to existing -documents, or it will locally improve the visual appearance of that -document without changing anything on other pages. However, by the -nature of the change it is also possible that there are further -non-local changes to the page breaks due to the different break -positions introduced by the fix. - -Thus, for documents that have been written before 2015 and that should -be preserved unchanged at all costs you may have to add -\begin{verbatim} -\RequirePackage[2014/01/01]{latexrelease} -\end{verbatim} -at the top of the document, to roll back the format to a date before -the policy change. - -\end{document} diff --git a/Master/texmf-dist/source/latex/base/ltnews27.tex b/Master/texmf-dist/source/latex/base/ltnews27.tex deleted file mode 100644 index 93281c19126..00000000000 --- a/Master/texmf-dist/source/latex/base/ltnews27.tex +++ /dev/null @@ -1,135 +0,0 @@ -% \iffalse meta-comment -% -% Copyright 2017 -% The LaTeX3 Project and any individual authors listed elsewhere -% in this file. -% -% This file is part of the LaTeX base system. -% ------------------------------------------- -% -% It may be distributed and/or modified under the -% conditions of the LaTeX Project Public License, either version 1.3c -% of this license or (at your option) any later version. -% The latest version of this license is in -% http://www.latex-project.org/lppl.txt -% and version 1.3c or later is part of all distributions of LaTeX -% version 2005/12/01 or later. -% -% This file has the LPPL maintenance status "maintained". -% -% The list of all files belonging to the LaTeX base distribution is -% given in the file `manifest.txt'.

This has many advantages over more -conventional formats, as it is easy to sort and avoids the unfortunate -ambiguity between different communities as to whether 01/02/2017 is the -1st of February or 2nd of January. - -However there is another date format, formalised by the -International Standard ISO~8601. The basic format defined by this -standard is functionally equivalent to the \LaTeX\ format, but using -\texttt{-} rather than \texttt{/}. This date format is now supported -in many Operating Systems and applications -(for example the \verb|date --iso-8601| command in Linux and similar systems). - -From this release, \LaTeX\ will accept ISO format date strings in the -date argument of \verb|\ProvidesPackage|, \verb|\usepackage|, etc. -Currently we recommend that you do not use this format in any packages -that need to work with older \LaTeX\ releases; -the \textsf{latexrelease} package may be used with older releases to - add this functionality. This change is handled in a special way by - \textsf{latexrelease}: The package always adds support for ISO dates -whatever format date is requested; this is required so that the -necessary date comparisons may be made. - -The new functionality can be seen in the startup banner which -advertises \texttt{LaTeX2e <2017-04-15>}. - -\section{Further TU encoding improvements} -The 2017/01/01 release saw the introduction of the new TU encoding for -specifying Unicode fonts with \hologo{LuaTeX} and -\hologo{XeTeX}. There were a number of small corrections and additions -in the patch releases updating 2017/01/01, and a further addition in -this release, notably extended support for the dot-under accent, -\verb|\d|. - - -\section{Disabling hyphenation} -The existing \LaTeX\ code for \verb|\verb| and \verb|verbatim| had some -issues when used with fonts that were not loaded with hyphenation -disabled via setting \verb|\hyphenchar| to $-1$. In this release these -verbatim environments use a \verb|\language| setting, -\verb|\l@nohyphenation|, that has no hyphenation patterns associated. - -The format ensures that a language has been allocated with this name. -For most users this will in fact be no change as the standard -\textsf{babel} language has for a long time allocated a language with -this name. - -In order that page breaks in \texttt{verbatim} do not influence the -language used in the page head and foot, the format now normalises the -language used in the output routine to a default language as described -below. - -\section{Discretionary hyphenation} -The \LaTeX\ definition of \verb|\-| has been adjusted so that it will -insert the current font's \verb|\hyphenchar|, as would the -\TeX\ primitive. A comment in \textsf{source2e} has given -this new definition since the first releases of \LaTeXe, and in this -release we finally acted upon this comment. Previously \verb|\-| -always inserted a \texttt{-} at a break point even if a different -character would be used for automatic hyphenation with the current font. - -\section{Default document language} - -A new integer parameter \verb|\document@default@language| is -introduced; this is initialised to $-1$ but is set at -\verb|\begin{document}| to the language in force at that time if it - has not been set by preamble code. This is very similar to the - handling of the default color, and is used in a similar way to - normalise the settings for page head and foot as described above. -Users should not normally need to set this explicitly but it is expected that -language packages such as \textsf{babel} may set this if the default -behaviour is not suitable. - -\section{Line spacing in parboxes} -Inside a \verb|\parbox| -\LaTeX\ normalises the baseline spacing. However it has not -previously reset \verb|\lineskiplimit|. This meant that -lines of a paragraph that have ascenders or descenders could be set -with \emph{closer} line spacing than lines without.

More details are given in~\cite{Mittelbach:TB39-1}. - -\section{Bug reports for core \LaTeXe{}} - -For more than two decades we used GNATS, an open source bug tracking -system developed by the FSF. While that has served us well in the past -it started to show its age more and more. So as part of this move we -also decided to finally retire the old \LaTeX{} bug database and replace -it with the standard ``Issue Tracker'' available at Github. - -The requirements and the workflow for reporting a bug in the core -\LaTeX{} software is documented at -\begin{quote} -\url{https://www.latex-project.org/bugs/} -\end{quote} -and with further details also discussed in~\cite{Mittelbach:TB39-1}. - - -\section{UTF-8: the new default input encoding} - -The first \TeX{} implementations only supported reading 7-bit -\acro{ascii} files---any accented or otherwise ``special'' character -had to be entered using commands, if it could be represented at -all. For example to obtain an ``\"a'' one would enter \verb=\"a=, and to -typeset a ``\ss'' the command \verb=\ss=. Furthermore fonts at that -time had 128 glyphs inside, holding the \acro{ascii} characters, some -accents to build composite glyphs from a letter and an accent, and a -few special symbols such as parentheses, etc. - -With 8-bit \TeX{} engines such as \hologo{pdfTeX} this situation changed -somewhat: it was now possible to process 8-bit files, i.e., files that -could encode 256 different characters. However, 256 is still a fairly -small number and with this limitation it is only possible to encode a -few languages and for other languages one would need to change the -encoding (i.e., interpret the character positions 0--255 in a -different way). The first code points 0--127 were essentially normed -(corresponding to \acro{ascii}) while the second half 128--255 would -vary by holding different accented characters to support a certain set -of languages. - -Each computer used one of these encodings when storing or interpreting -files and as long as two computers used the same encoding it was -(easily) possible to exchange files between them and have them -interpreted and processed correctly. - -But different computers may have used different encodings and given -that a computer file is simply a sequence of bytes with no indication for -which encoding is intended, chaos could easily happen and has -happened. For example, the German word ``Gr\"o\ss e'' (height) entered on a -German keyboard could show up as ``Gr\v T\`ae'' on a different -computer using a different encoding by default. - -So in summmary the situation wasn't at all good and it was clear in -the early nineties that \LaTeXe{} (that was being developed to provide -a \LaTeX{} version usable across the world) had to provide a solution -to this issue. - -The \LaTeXe{} answer was the introduction of the \package{inputenc} -package~\cite{Mittelbach:Brno95} through which it is possible to -provide support for multiple encodings. It also allows to correctly -process a file written in one encoding on a computer using a different -encoding and even supports documents where the encoding changes -midway. - -Since the first release of \LaTeXe{} in 1994, \LaTeX{} documents that -used any characters outside \acro{ascii} in the source (i.e. any -characters in the range of 128--255) were supposed to load -\package{inputenc} and specify in which file encoding they were -written and stored. -% -If the \package{inputenc} package was not loaded then \LaTeX{} used a -``raw'' encoding which essentially took each byte from the input file -and typeset the glyph that happened to be in that position in the -current font---something that sometimes produces the right result but -often enough will not. - -In 1992 Ken Thompson and Rob Pike developed the UTF-8 encoding scheme -which enables the encoding of all Unicode characters within 8-bit sequences. -Over time this encoding has gradually taken over the world, -replacing the legacy 8-bit encodings used before. These days all major -computer operating systems use UTF-8 to store their files and it -requires some effort to explicitly store files in one of the legacy -encodings. - -As a result, whenever \LaTeX{} users want to use any accented -characters from their keyboard (instead of resorting to \verb=\"a= and -the like) they always have to use -\begin{verbatim} - \usepackage[utf8]{inputenc} -\end{verbatim} -in the preamble of their documents as otherwise \LaTeX{} will produce -gibberish. - -\subsection{The new default} - -With this release, the default encoding for \LaTeX\ files has been -changed from the ``fall through raw'' encoding to UTF-8 if used with -classic \TeX\ or \hologo{pdfTeX}. The implementation is essentially -the same as the existing UTF-8 support from -\verb|\usepackage[utf8]{inputenc}|. - -The \hologo{LuaTeX} and \hologo{XeTeX} engines always supported the -UTF-8 encoding as their native (and only) input encoding, so with -these engines \package{inputenc} was always a no-op. - -This means that with new documents one can assume UTF-8 input and it -is no longer required to always specify -\verb|\usepackage[utf8]{inputenc}|. But if this line is present it -will not hurt either. - - -\subsection{Compatibility} - -For most existing documents this change will be transparent: -\begin{itemize} -\item documents using only \acro{ascii} in the input file and - accessing accented characters via commands; -\item documents that specified the encoding of their file via an - option to the \package{inputenc} package and then used 8-bit - characters in that encoding; -\item documents that already had been stored in UTF-8 (whether or not - specifying this via \package{inputenc}). -\end{itemize} -Only documents that have been stored in a legacy encoding and used -accented letters from the keyboard \emph{without} loading -\package{inputenc} (relying on the similarities between the input used -and the T1 font encoding) are affected. - -These documents will now generate an error that they contain invalid -UTF-8 sequences. However, such documents may be easily processed by -adding the new command \verb|\UseRawInputEncoding| as the first line -of the file. This will re-instate the previous ``raw'' encoding -default. - -\verb|\UseRawInputEncoding| may also be used on the command line to -process existing files without requiring the file to be edited -\begin{verbatim} - pdflatex '\UseRawInputEncoding \input' file -\end{verbatim} -will process the file using the previous default encoding. - -Possible alternatives are reencoding the file to UTF-8 using a tool -(such as recode or iconv or an editor) or adding the line -\begin{flushleft} -\verb= \usepackage[=\meta{encoding}\verb=]{inputenc}= -\end{flushleft} -to the preamble specifying the \meta{encoding} that fits the file -encoding. In many cases this will be \texttt{latin1} or -\texttt{cp1252}. For other encoding names and their meaning see the -\package{inputenc} documentation. - -As usual, this change may also be reverted via the more general -\package{latexrelease} package mechanism, by speciying a release date -earlier than this release. - - -\subsection{BOM: byte order mark handling} - -When using Unicode the first bytes of a file may be a, so called, BOM -character (byte order mark) to indicate the byte oder used in the -file. While this is not required with UTF-8 encoded files (where the -byte order is known) it is nevertheless allowed by the standard and -some editors add that byte sequence to the beginning of a file. In the -past such files would have generated a ``Missing begin document'' -error or displayed strange characters when loaded at a later stage. - -With the addition of UTF-8 support to the kernel it is now possible to -identify and ignore such BOMs characters even before -\verb=\documentclass= so that these issues will no longer be showing -up. - - - -\section[A general rollback concept] - {A general rollback concept for packages and classes} - - In 2015 a rollback concept for the \LaTeX{} kernel was introduced. - Providing this feature allowed us to make corrections to the - software (which more or less didn't happen for nearly two decades) - while continuing to maintain backward compatibility to the highest - degree. - - In this release we have now extended this concept to - the world of packages and classes which was not covered - initially. As the classes and the extension packages have different - requirements compared to the kernel, the approach is different (and - simplified). This should make it easy for package developers to - apply it to their packages and authors to use when necessary. - - The documentation of this new feature is given in an article - submitted to TUGboat and also available from our - website~\cite{Mittelbach:TB39-2}. - - -\section[Integration of \pkg{remreset} and \pkg{chngcntr} packages] - {Integration of \pkg{remreset} and \pkg{chngcntr} packages - into the kernel} - -With the optional argument to \cs{newcounter} \LaTeX{} offers to -automatically reset counters when some counter is stepped, e.g., -stepping a \texttt{chapter} counter resets the \texttt{section} -counter (and recursively all other heading counters). However, what -was until now missing was a way to undo such a link between counters -or to link two counters after they have been defined. - -This can be now be done with \cs{counterwithin} and \cs{counterwithout}, -respectively. In the past one had to load the \pkg{chngcntr} package -for this. For the programming level we also added -\cs{@removefromreset} as the counterpart of the already existing -\cs{@addtoreset} command. Up to now this was offered by the -\pkg{remreset} package. - -\section{Testing for undefined commands} -\LaTeX\ packages often use a test \verb|\@ifundefined| to test if a command -is defined. Unfortunately this had the side effect of \emph{defining} -the command to \verb|\relax| in the case that it had no definition. - The new release uses a modified definition -(using extra testing possibilities available in \hologo{eTeX}. The new definition -is more natural, however code that was relying on the side effect of the -command being tested being defined if it was previously undefined may have to add -\verb|\let\|\meta{command}\verb|\relax|. - - -\section{Changes to packages in the tools category} - -\subsection{\LaTeX{} table columns with fixed widths} - -Frank published a short paper in -TUGboat~\cite{Mittelbach:TB38-2-213} on producing tables that have -columns with fixed widths.

These correct - names are in addition to the old (but wrong) Adobe names: Adobe - mistakenly called them Guillemot, which is a sea bird. -% - \githubissue{65} -% -\item - Added \cs{Hwithstroke} and \cs{hwithstroke} necessary for - typesetting Maltese. -% - \sxissue{https://tex.stackexchange.com/q/460110} -\end{itemize} - - - -\subsection{Fixed \cs{verb*} and friends in \XeTeX{} and \LuaTeX{}} - - -The original \cs{verb*} and \texttt{verbatim*} in \LaTeX{} were coded -under the assumption that the position of the space character (i.e., -ASCII 32) in a Typewriter Font contains a visible space glyph -``\verb*= =''. This is correct for \pdfTeX{} with the most used font -encodings \texttt{OT1} and \texttt{T1}. However, this unfortunately -does not work for Unicode engines using the \texttt{TU} encoding since -the space character slot (ASCII 32) then usually contains a real -(normal) space, which has the effect that \cs{verb*} produces the same -results as \cs{verb}. - -The \cs{verb*} code now always uses the newly introduced command -\cs{verbvisiblespace} to produce the visible space character and this -command will get appropriate definitions for use with the different -engines. With \pdfTeX{} it will simply use \cs{asciispace}, which is -a posh name for ``select character 32 in the current font'', but with -Unicode engines the default definition is -\begin{verbatim} - \DeclareRobustCommand\verbvisiblespace - {\leavevmode - {\usefont{OT1}{cmtt}{m}{n}\asciispace}} -\end{verbatim} -which uses the visible space from the font Computer Modern Typewriter, -regardless of the currently chosen typewriter font. Internally the -code ensures that the character used has exactly the same width as the -other characters in the current (monospaced) font; thus, for example, -code displays line up properly. - -It is possible to redefine this command to select your own character, -for example -\begin{verbatim} - \DeclareRobustCommand\verbvisiblespace - {\textvisiblespace} -\end{verbatim} -will select the the ``official'' visible space character of the -current font. This may look like the natural default, but it wasn't -chosen as our default because many fonts just don't have that unicode -character, or they have one with a strange shape. -% -\githubissue[s]{69 and 70} - - -\subsection{Error message corrected} -Trying to redefine an undefined command could in a few cases generate -an error message with a missing space, e.g., -\verb=\renewcommand\1{...}= gave -\begin{verbatim} - LaTeX Error: \1undefined. -\end{verbatim} -This is now fixed. -% -\githubissue{41} - - -\subsection{Fixed fatal link error with \pkg{hyperref}} - -If a \cs{href} link text gets broken across pages \pdfTeX{} and -\LuaTeX{} will generate a fatal error unless both parts of the link -are internally at the same boxing level. In two-column mode that was -not the case if one of the pages had spanning top floats. This has now -been changed so that the error is avoided. -% -\githubissue{94} - - -\subsection{Avoid page breaks caused by invisible commands} - -Commands like \cs{label} or \cs{index} could generate a potential page -break in places where a page break was otherwise prohibited, e.g., -when used between two consecutive headings. This has now been -corrected. If for some reason you really want a break and you relied -on this faulty behavior, you can always add one using \cs{pagebreak}, -with or without an optional argument. -% -\githubissue{81} - - - -\subsection{Prevent spurious spaces when reading table of contents data} - -When table of contents data is read in from a \texttt{.toc} file, the -new-line character at the end of each line is converted by \TeX{} to a -space. In normal processing this is harmless (as \TeX{} is doing this -input reading whilst in vertical mode and each line in the file -represents a single line (paragraph) in the table of contents. If, -however, this is done in horizontal mode, which is sometimes the case, -then these spaces will appear in the output. If you then omit some of -the input lines (e.g., because you do not display TOC data below a -certain level), then these spaces accumulate in the typeset output and -you get surprising, and unwanted, gaps inside the text. - -The new code now adds a \texttt{\%} sign at the end of problematic -lines in the \texttt{.toc} file so that \TeX{} will not generate such -spaces that may survive to spoil the printed result. As some third -party packages have augmented or changed the core \LaTeX{} -functionality in that area (for example, by adding additional -arguments to the commands in TOC files) the code uses a conservative -approach and the \texttt{\%} signs are added only when certain -conditions are met. Therefore some packages might require updates if -they want to benefit from this correction, especially if they -unconditionally overwrite \LaTeX{}'s \cs{addcontentsline} definition. -% -\githubissue{73} - - -\subsection{Prevent protrusion in table of contents lines} - -In \TeX{}'s internal processing model, -paragraph data is one of the -major data structures. As a result, -many things are internally modeled -as paragraphs even if they are not conceptually -``text paragraphs'' in -the traditional sense. -In a few cases this has some surprising effects -that are not always -for the better. One example is -standard TOC entries, -where you have -heading data followed by some dot leaders and a page -number at the right, produced, for example, from this: -\begin{quote} - \contentsline {subsection}{Error message corrected}{2}{section*.7} -\end{quote} -The space reserved for the page number is of a fixed width, so that -the dots always end in the same place. Well, they did end in the same -place until the event of protrusion support in the \TeX{} engines. -Now, with the \pkg{microtype} package loaded, it is possible that the -page number will protrude slightly into the margin (even though it’s -typeset inside a box) and as a result this page number box gets -shifted. With enough bad luck this can get you another dot in the -line, sticking out like the proverbial sore thumb, as exhibited in the -question on StackExchange that triggered the correction. - -\LaTeX{} now takes care that there will be no protrusion happening on -such lines, even if it is generally enabled for the whole document. -% -\sxissue{https://tex.stackexchange.com/q/172785} - - - -\subsection{Start L-R mode for \cs{thinspace} and friends} - -In \LaTeX{}, commands that are intended only for paragraph (L-R) mode -are generally careful to start paragraph mode if necessary; thus they -can be used at the start of a paragraph without surprising and -unwanted consequences. This important requirement had been overlooked -for a few horizontal spacing commands, such as \cs{thinspace} -(a.k.a.\ ``\cs{,}''), and for some other support commands such as -\cs{smash} or \cs{phantom}. Thus they ended up adding vertical space -when used at the beginning of a paragraph or, in the case of -\cs{smash}, creating a paragraph of their own. This has now been -corrected, and a corresponding update has been made to the -\pkg{amsmath} package, in which these commands are also defined. -% -\githubissue[s]{49 and 50} - - - -\subsection{Guarding \cs{pfill} in \pkg{doc}} - -For presenting index entries pointing to -code fragments and the like, -the \pkg{doc} package has a \cs{pfill} command that -generates within the index a line of dots leading from -the command name to the page or code line numbers. -If necessary it would automatically split the entry -over two lines. That worked well enough for a quarter century, but we -discovered recently that it is broken inside -the \cls{ltugboat} class, -where it sometimes produces -bad spacing within continuation lines. - -The reason turned out to be a redefinition of the \LaTeX{} command -\cs{nobreakspace} (\verb=~=) inside the class \cls{ltugboat}, which -removed any preceding space (and thus unfortunately also removed the -dots on the continuation line). While one can argue that this is a -questionable redefinition, it has been in the class so long that -changing it would certainly break older documents. So instead we now -guard against that removal of space. -% -\githubissue[s]{25 and 75} - - - - - -\section{Changes to packages in the \pkg{tools} category} - -\subsection{Sometimes the \pkg{trace} package turned off too much} - -The \pkg{trace} package is a useful little tool for tracing macro -execution: it hides certain lengthy and typically uninteresting -expansions resulting from font changes and similar activities. -However, it had the problem that it also reset other tracing settings -such as \cs{showoutput} in such situations, so that you couldn't use -\cs{showoutput} in the preamble to get symbolic output of all the -pages in the document. This has now been corrected. - - - - -\subsection{Update to \pkg{xr}} - -The \pkg{xr} package has been updated so that the code that reads the -\texttt{.aux} file has been made more robust. It now correctly -ignores conditionals (added by \pkg{hyperref} and other packages) -rather than generating low level parsing errors. -\sxissue{https://tex.stackexchange.com/a/452321} - - -\subsection{Column data for \env{multicols*} sometimes vanished} - -In certain situations involving \env{multicols*}, when there are more -explicit \cs{columnbreak} requests than there are columns on the -current page, data could vanish due to the removal of an internal -penalty marking the end of the environment. This has been corrected by -explicitly reinserting that penalty if necessary. -% -\githubissue{53} - -\subsection{Extension to \cs{docolaction} in \pkg{multicol}} - -The \cs{docolaction} command can be used used to carry out actions -depending on the column you are currently in, i.e., first, any inner -one (if more than two) or last. However, if the action generates text -then there is the question: is this text part of the current column or -the one after? That is, on the next run, do we test before or after it, -to determine in which column we are? - -This is now resolved as follows: if you use \cs{docolaction*} any -generated text by the chosen action is considered to be after the test -point. But if you use the command without the star then all the material -it generates will be placed before the test point to determine the -current column, i.e., the text will become part of the current column -and may affect the test result on the next run. - - - -\subsection{Prevent color leak in \pkg{array}} - -In some cases the color used inside a \env{tabular} cell could ``leak -out'' into the surrounding text. This has been corrected. -% -\githubissue{72} - -\subsection{Support fragile commands in \texttt{array} or \texttt{tabular} column templates} - -The preamble specifiers \texttt{p}, \texttt{m} and \texttt{b} each receives -a user supplied argument: the width of the paragraph column. Normally -that is something harmless, like a length or a simple length -expression. But in more complicated settings involving the \pkg{calc} -package it could break with a low-level error message. This has now -been corrected. -% -\sxissue{https://tex.stackexchange.com/q/459285} - - - -\section{Changes to packages in the amsmath category} - -The changes in the kernel made for \cs{thinspace}, \cs{smash}, -etc.\ (see above) have been reflected in the \pkg{amsmath} package -code, so that loading this package doesn't revert them. -% -\githubissue[s]{49 and 50} - - - - - -\section{Website updates} - -\subsection{Publications area reorganized and extended} - -To help readers to find relevant information in more convenient and -easy ways, the area of the website covering publications by the -\LaTeX{} Project Team was reorganized and extended (many more -abstracts added).
