+Effective in 2016, maintenance of `amsmath was transferred from AMS to
+the LaTeX Project; as `amsmath` is considered a "required" package, this
 centralizes control over the core LaTeX components.
 
+Installation
+------------
 
-### INSTALLATION AND GETTING STARTED
+We no longer distribute installation instructions for the various TeX
+implementations. All modern TeX systems include `amsmath` as-standard, and end
+users should in general use the release versions supplied in this way.
 
-In order to use amsmath you need to have TeX installed first.
-For information on getting TeX see one of the following:
+Release distribution is carried out only through the CTAN archives.
 
- - [LaTeX Project Website](https://www.latex-project.org/)
- - [TeX User Group](https://www.tug.org/)
- - [TeX resources (AMS infos for authors)](https://www.ams.org/tex/tex-resources)
+Documentation
+-------------
 
-It is recommended to install a comprehensive distribution, such as
-TeX Live, MiKTeX for Windows, or MacTeX for Macintosh.
-As part of the "required" LaTeX package subset, amsmath
-will already be available if one of these distributions is chosen.
-
-If you are installing amsmath manually, the most recent version
-will be available from the CTAN archives
-https://www.ctan.org/pkg/amsmath
-
-
-The primary documentation for amsmath is in
-
- - amsldoc.pdf
+The primary documentation for `amsmath` is in provided as `amsldoc.pdf`.
 
 Additional documentation files include:
 
- - diffs-m.txt
- - subeqn.pdf
- - technote.pdf
- - testmath.pdf
+ - `diffs-m.txt`
+ - `subeqn.pdf`
+ - `technote.pdf`
+ - `testmath.pdf`
 
 which are included in the collection.  All of these can be accessed
 easily with most distributions by entering `texdoc` *filename* at the
 command line, or via [TeXdoc Online](http://texdoc.net).

+The LaTeX kernel
+================
+
+Release 2019-10-01
+
+Overview
+--------
+
+This bundle provides the core LaTeX kernel. In addition to this bundle,
+a minimal LaTeX system also needs the files contained in the
+
+- LaTeX team documentation (`doc`)
+- Packages which must be available (`required`). These are
+  - Essential tools (`tools`)
+  - Core graphics and color support (`graphics`)
+  - Key mathematics support (`amsmath`)
+
+This file contains a small set of pointers to other more complete
+documentation on installing and using a LaTeX system.
+
+Documentation
+-------------
+
+Full documentation of the LaTeX system is provided by
+
+- _LaTeX: A Document Preparation System_; Lamport, Addison-Wesley
+- _The LaTeX Companion_, 2ed; Mittelbach and Goossens with Braams, Carlisle
+  and Rowley, Addison-Wesley
+- _Guide to LaTeX_, 4ed; Kopka and Daly, Addison-Wesley
+
+The distribution is described in files ending `.txt` or `.md`; briefly,
+the most significant of these files are
+
+- `README.md` is this file
+- `manifest.txt` lists all the files in this LaTeX distribution,
+   with one line of information about the contents
+- `unpacked.txt` lists all the files in the unpacked LaTeX distribution
+- `legal.txt` and `lppl.txt` (LaTeX Project Public License) describe the 
+   LaTeX copyright, warranty and copying restrictions.
+- `patches.txt` describes the how important changes will be distributed
+   between releases
+- `texpert.txt` contains information about the system that may still be
+   useful for TeX experts
+- `tex2.txt` contains important information for users of extremely
+   old versions of TeX (pre 1990)
+- `autoload.txt` describes a variant of LaTeX that is no longer supported
+- `bugs.txt` describes how to submit a bug report for LaTeX
+
+Other documentation files include files with names of the form:
+
+   <xxx>guide.tex
+
+You will probably need to update your system before you can typeset
+these files.  Each file needs three LaTeX runs.  Some of these are
+also available as PDF files on [CTAN](https://www.ctan.org).
+
+The following files contain further information:
+
+- `ltx3info.tex` gives you some historical information about the LaTeX3
+   project
+- `manual.err` lists errata in _LaTeX: A Document Preparation System_ (Lamport)
+- `tlc2.err` lists errata in _The LaTeX Companion_ (Mittelbach et al.)
+
+The files `ltnews*.tex` (part of the `doc` bundle) contain the LaTeX
+newsletters, the highest number being the most recent. 
+
+For historical reasons, the base distribution and the core documentation
+are bundled separately. Documentation is found in the `doc` bundle. In an
+installed TeX system, `base` and `doc` should be placed within the same
+location; the distinction is therefore primarily of importance when looking
+at the development code.
+
+Installation
+------------
+
+We no longer distribute installation instructions for the various TeX
+implementations. All modern TeX systems include LaTeX as-standard, and end
+users should in general use the release versions supplied in this way.
+
+Release distribution is carried out only through the CTAN archives.
+
+Requirements
+------------
+
+The LaTeX kernel requires the e-TeX extensions to TeX, which were finalised
+in the late 1990s and are available in modern TeX-derived engines. Some new
+features require `\ifincsname`, which is currently available in release
+versions of pdfTeX, XeTeX and LuaTeX, and is being introduced shortly in
+e-pTeX and e-upTeX.
+
+License
+-------
+
+The contents of this bundle are distributed under the [LaTeX Project
+Public License](https://www.latex-project.org/lppl/lppl-1-3c/),
+version 1.3c or later.

+\LaTeX\ format since the 2014/05/01 \LaTeX\ release.
+
 
 As announced in \ltnewsissue{22}, the 2015 \LaTeX{} release adopts a new
 policy. Improvements and bug fixes will be made to the format sources,
 with the \Lpack{latexrelease} package being available to revert
 changes to use definitions from an earlier format.
 
-\section{Changes  introduced in 2018-12-01}

+\section{Changes introduced in 2019-10-01}
+
+Introduced \LaTeX\texttt{-dev} formats for pre testing future \LaTeX{}
+releases. Now there's a \texttt{latex-base-dev} package on CTAN which
+contains a pre-release of the \LaTeXe{} kernel and both \TeX Live and
+MiK\TeX{} include the standard \LaTeX{} executables (\texttt{pdflatex},
+\texttt{lualatex}, etc.) with \texttt{-dev} appended, which use the
+pre-release format.
+
+The handling of Unicode characters was improved by making them safe
+inside \verb|\ref|s and \verb|\label|s, by using \verb|\ifincsname|
+to make these characters safe in these contexts (\ghissue{95}).
+
+In line with the better handling of Unicode characters, file names
+can now contain any Unicode character plus spaces, as these cases
+are now correctly handled by the kernel.
+
+An optional argument was added to the \texttt{filecontents} environment,
+to which a comma-separated list of options can be given. The options
+include \texttt{overwrite} (or \texttt{force}), \texttt{nosearch}, and
+\texttt{noheader} (which has the same effect as the starred form of the
+environment). The environment is now allowed anywhere in the document.
+
+A plethora of \LaTeX{} commands was made robust so that fewer
+\verb|\protect| are needed when using some commands in moving arguments.
+There are a few border cases where it's tricker to make the command
+robust or where it's not worth it to do so, but most reasonable use
+cases are covered. The most notable change was \verb|\begin| and
+\verb|\end|, which are now robust and won't break when used in moving
+arguments.
+
+An extra \verb|\hskip 1sp| was added to \verb|c|-column table cells to
+protect against the presence of an \verb|\unskip| in the table cell
+(\ghissue{102}).
+
+\texttt{U+012F} which is ``i with ogonek'' should produce an
+``i'' and not a ``dotless i''. This has been corrected
+(\ghissue{122}).
+
+The Unicode slots \texttt{27E8} and \texttt{27E9} have been mapped to
+\verb|textlangle| and \verb|textrangle| which is the recommended mapping
+(\ghissue{110}).
+
+Basic ligatures (ff, fi, fl, ffi, ffl, ft, st) can now be input as a
+single unicode character in pdf\TeX, which is useful when copy-pasting
+(\ghissue{154}).
+
+\verb|\InputIfFileExists{foo}{\input{bar}}{}|
+did not load the files \texttt{foo.tex} and \texttt{bar.tex} but
+would load \texttt{bar.tex} twice. This has been corrected (\ghissue{109}).
+
+The \textsf{fncylab} and \textsf{varioref} packages changed \LaTeX's internal
+counter prefix commands \verb|p@...| so that they would take the counter
+value as an argument instead of just acting as a prefix to them. These
+packages also provided the \verb|\labelformat| macro to change the prefix
+macro and \verb|\Ref| so that using counters defined that way in the
+beginning of sentences would have the proper capitalisation. These features
+were added to the \LaTeXe{} kernel.
+
+The kernel now says ``Trying to load\ldots''
+instead of ``Try loading \ldots'' in one of its informal
+messages to match style of similar messages (\ghissue{107}).
+
+\verb|\DeclareErrorFont| would change the font size to 10\,pt which, when
+used in the wrong place, would make incorrect font settings in the document.
+This has now been fixed (\gnatsissue{4399}).
+
+The default action of the file \texttt{nfssfont.tex} was set to produce a
+font table, so that one can simply hit enter instead of having to write
+\verb=\table\bye=.
+
+The \LaTeX{} kernel now provides dummy (empty) definitions for the
+commands \verb|\conditionally@traceoff| and
+\verb|\conditionally@traceon| from the \texttt{trace} package so they
+can be used by package developers without worrying about them being
+defined or not (\ghissue{164}).
+
+
+
+
+
+\section{Changes introduced in 2018-12-01}
 
 Further additions to the characters supported by default in UTF-8.
-\verb|\guillemetleft| and \verb|\guillemetright| provided as alias for
-the names based on the Adobe font names (\ghissue{65}).
+The commands \verb|\guillemetleft| and \verb|\guillemetright| are

+New commands \verb|\Hwithstroke| and \verb|\hwithstroke| added to T1 encoding support.
 
 The internal box structure for floats is adjusted to preserve box
 levels of split hyperlinks, avoiding a fatal pdftex error. \ghissue{94}.

 Improved support for non ASCII filenames on the commandline on
 filesystems using legacy encodings.

-will be made between all those with the largest number of findings).
-A person can receive at most one prize, ever; errors found by any of

-Each prize is a free choice of any single computing book found on the
-AW Professional web site \texttt{http://www.awprofessional.com} (that

-
-As usual, the authors and publisher reserve the right to make various

-  \label{LPPL:Preamble}
-  
-  The \LaTeX\ Project Public License (\LPPL) is the primary license
-  under which the \LaTeX\ kernel and the base \LaTeX\ packages are
-  distributed.
-
-  You may use this license for any work of which you hold the
-  copyright and which you wish to distribute.  This license may be
-  particularly suitable if your work is \TeX-related (such as a
-  \LaTeX\ package), but it is written in such a way that you can use 
-  it even if your work is unrelated to \TeX.
-
-  The section `WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS
-  LICENSE', below, gives instructions, examples, and recommendations
-  for authors who are considering distributing their works under this
-  license.
-
-  This license gives conditions under which a work may be distributed
-  and modified, as well as conditions under which modified versions of
-  that work may be distributed.
-
-  We, the \LaTeX3 Project, believe that the conditions below give you
-  the freedom to make and distribute modified versions of your work
-  that conform with whatever technical specifications you wish while
-  maintaining the availability, integrity, and reliability of that
-  work.  If you do not see how to achieve your goal while meeting
-  these conditions, then read the document \LPPLdocfile{cfgguide} and
-  \LPPLdocfile{modguide} in the base \LaTeX\ distribution for suggestions.
-
-
-  \LPPLsubsection{Definitions}
-  \label{LPPL:Definitions}
-
-  In this license document the following terms are used:
-
-  \begin{description}
-  \item[Work] Any work being distributed under this License.
-
-  \item[Derived Work] Any work that under any applicable law is
-    derived from the Work.
-
-  \item[Modification] Any procedure that produces a Derived Work under
-    any applicable law -- for example, the production of a file
-    containing an original file associated with the Work or a
-    significant portion of such a file, either verbatim or with
-    modifications and/or translated into another language.
-
-  \item[Modify] To apply any procedure that produces a Derived Work
-    under any applicable law.
-    
-  \item[Distribution] Making copies of the Work available from one
-    person to another, in whole or in part.  Distribution includes
-    (but is not limited to) making any electronic components of the
-    Work accessible by file transfer protocols such as \textsc{ftp} or
-    \textsc{http} or by shared file systems such as Sun's Network File
-    System (\textsc{nfs}).
-
-  \item[Compiled Work] A version of the Work that has been processed
-    into a form where it is directly usable on a computer system.
-    This processing may include using installation facilities provided
-    by the Work, transformations of the Work, copying of components of
-    the Work, or other activities.  Note that modification of any
-    installation facilities provided by the Work constitutes
-    modification of the Work.
-
-  \item[Current Maintainer] A person or persons nominated as such
-    within the Work.  If there is no such explicit nomination then it
-    is the `Copyright Holder' under any applicable law.
-
-  \item[Base Interpreter] A program or process that is normally needed
-    for running or interpreting a part or the whole of the Work.
-    
-    A Base Interpreter may depend on external components but these are
-    not considered part of the Base Interpreter provided that each
-    external component clearly identifies itself whenever it is used
-    interactively.  Unless explicitly specified when applying the
-    license to the Work, the only applicable Base Interpreter is a
-    `\LaTeX-Format' or in the case of files belonging to the
-    `\LaTeX-format' a program implementing the `\TeX{} language'.
-  \end{description}
-
-  \LPPLsubsection{Conditions on Distribution and Modification}
-  \label{LPPL:Conditions}
-
-  \begin{enumerate}
-  \item Activities other than distribution and/or modification of the
-    Work are not covered by this license; they are outside its scope.
-    In particular, the act of running the Work is not restricted and
-    no requirements are made concerning any offers of support for the
-    Work.
-
-  \item\label{LPPL:item:distribute} You may distribute a complete, unmodified
-    copy of the Work as you received it.  Distribution of only part of
-    the Work is considered modification of the Work, and no right to
-    distribute such a Derived Work may be assumed under the terms of
-    this clause.
-
-  \item You may distribute a Compiled Work that has been generated
-    from a complete, unmodified copy of the Work as distributed under
-    Clause~\ref{LPPL:item:distribute} above, as long as that Compiled Work is
-    distributed in such a way that the recipients may install the
-    Compiled Work on their system exactly as it would have been
-    installed if they generated a Compiled Work directly from the
-    Work.
-
-  \item\label{LPPL:item:currmaint} If you are the Current Maintainer of the
-    Work, you may, without restriction, modify the Work, thus creating
-    a Derived Work.  You may also distribute the Derived Work without
-    restriction, including Compiled Works generated from the Derived
-    Work.  Derived Works distributed in this manner by the Current
-    Maintainer are considered to be updated versions of the Work.
-
-  \item If you are not the Current Maintainer of the Work, you may
-    modify your copy of the Work, thus creating a Derived Work based
-    on the Work, and compile this Derived Work, thus creating a
-    Compiled Work based on the Derived Work.
-
-  \item\label{LPPL:item:conditions} If you are not the Current Maintainer 
-    of the
-    Work, you may distribute a Derived Work provided the following
-    conditions are met for every component of the Work unless that
-    component clearly states in the copyright notice that it is exempt
-    from that condition.  Only the Current Maintainer is allowed to
-    add such statements of exemption to a component of the Work.
-    \begin{enumerate}
-    \item If a component of this Derived Work can be a direct
-      replacement for a component of the Work when that component is
-      used with the Base Interpreter, then, wherever this component of
-      the Work identifies itself to the user when used interactively
-      with that Base Interpreter, the replacement component of this
-      Derived Work clearly and unambiguously identifies itself as a
-      modified version of this component to the user when used
-      interactively with that Base Interpreter.
-     
-    \item\label{LPPL:item:changelog} Every component of the Derived Work
-      contains prominent
-      notices detailing the nature of the changes to that component,
-      or a prominent reference to another file that is distributed as
-      part of the Derived Work and that contains a complete and
-      accurate log of the changes.
-  
-    \item No information in the Derived Work implies that any persons,
-      including (but not limited to) the authors of the original
-      version of the Work, provide any support, including (but not
-      limited to) the reporting and handling of errors, to recipients
-      of the Derived Work unless those persons have stated explicitly
-      that they do provide such support for the Derived Work.
-
-    \item\label{LPPL:item:unmodifiedcopy} You distribute at least one of
-      the following with the Derived Work:
-      \begin{enumerate}
-      \item A complete, unmodified copy of the Work; if your
-        distribution of a modified component is made by offering
-        access to copy the modified component from a designated place,
-        then offering equivalent access to copy the Work from the same
-        or some similar place meets this condition, even though third
-        parties are not compelled to copy the Work along with the
-        modified component;
-
-      \item Information that is sufficient to obtain a complete,
-        unmodified copy of the Work.
-      \end{enumerate}
-    \end{enumerate}
-  \item If you are not the Current Maintainer of the Work, you may
-    distribute a Compiled Work generated from a Derived Work, as long
-    as the Derived Work is distributed to all recipients of the
-    Compiled Work, and as long as the conditions of
-    Clause~\ref{LPPL:item:conditions}, above, are met with regard to the 
-    Derived Work.
-
-  \item The conditions above are not intended to prohibit, and hence
-    do not apply to, the modification, by any method, of any component
-    so that it becomes identical to an updated version of that
-    component of the Work as it is distributed by the Current
-    Maintainer under Clause~\ref{LPPL:item:currmaint}, above.
-
-  \item Distribution of the Work or any Derived Work in an alternative
-    format, where the Work or that Derived Work (in whole or in part)
-    is then produced by applying some process to that format, does not
-    relax or nullify any sections of this license as they pertain to
-    the results of applying that process.
-     
-  \item 
-    \begin{enumerate}
-    \item A Derived Work may be distributed under a different license
-      provided that license itself honors the conditions listed in
-      Clause~\ref{LPPL:item:conditions} above, in regard to the Work, though it
-      does not have to honor the rest of the conditions in this
-      license.
-      
-    \item If a Derived Work is distributed under a different license,
-      that Derived Work must provide sufficient documentation as part
-      of itself to allow each recipient of that Derived Work to honor
-      the restrictions in Clause~\ref{LPPL:item:conditions} above, concerning
-      changes from the Work.
-    \end{enumerate}
-  \item This license places no restrictions on works that are
-    unrelated to the Work, nor does this license place any
-    restrictions on aggregating such works with the Work by any means.
-
-  \item Nothing in this license is intended to, or may be used to,
-    prevent complete compliance by all parties with all applicable
-    laws.
-  \end{enumerate}
-
-  \LPPLsubsection{No Warranty}
-  \label{LPPL:Warranty}
-
-  There is no warranty for the Work.  Except when otherwise stated in
-  writing, the Copyright Holder provides the Work `as is', without
-  warranty of any kind, either expressed or implied, including, but
-  not limited to, the implied warranties of merchantability and
-  fitness for a particular purpose.  The entire risk as to the quality
-  and performance of the Work is with you.  Should the Work prove
-  defective, you assume the cost of all necessary servicing, repair,
-  or correction.
-
-  In no event unless required by applicable law or agreed to in
-  writing will The Copyright Holder, or any author named in the
-  components of the Work, or any other party who may distribute and/or
-  modify the Work as permitted above, be liable to you for damages,
-  including any general, special, incidental or consequential damages
-  arising out of any use of the Work or out of inability to use the
-  Work (including, but not limited to, loss of data, data being
-  rendered inaccurate, or losses sustained by anyone as a result of
-  any failure of the Work to operate with any other programs), even if
-  the Copyright Holder or said author or said other party has been
-  advised of the possibility of such damages.
-
-  \LPPLsubsection{Maintenance of The Work}
-  \label{LPPL:Maintenance}
-
-  The Work has the status `author-maintained' if the Copyright Holder
-  explicitly and prominently states near the primary copyright notice
-  in the Work that the Work can only be maintained by the Copyright
-  Holder or simply that it is `author-maintained'.
-
-  The Work has the status `maintained' if there is a Current
-  Maintainer who has indicated in the Work that they are willing to
-  receive error reports for the Work (for example, by supplying a
-  valid e-mail address). It is not required for the Current Maintainer
-  to acknowledge or act upon these error reports.
-
-  The Work changes from status `maintained' to `unmaintained' if there
-  is no Current Maintainer, or the person stated to be Current
-  Maintainer of the work cannot be reached through the indicated means
-  of communication for a period of six months, and there are no other
-  significant signs of active maintenance.
-
-  You can become the Current Maintainer of the Work by agreement with
-  any existing Current Maintainer to take over this role.
-
-  If the Work is unmaintained, you can become the Current Maintainer
-  of the Work through the following steps:
-  \begin{enumerate}
-  \item Make a reasonable attempt to trace the Current Maintainer (and
-    the Copyright Holder, if the two differ) through the means of an
-    Internet or similar search.
-  \item If this search is successful, then enquire whether the Work is
-    still maintained.
-    \begin{enumerate}
-    \item If it is being maintained, then ask the Current Maintainer
-      to update their communication data within one month.
-     
-    \item\label{LPPL:item:intention} If the search is unsuccessful or
-      no action to resume active maintenance is taken by the Current
-      Maintainer, then announce within the pertinent community your
-      intention to take over maintenance.  (If the Work is a \LaTeX{}
-      work, this could be done, for example, by posting to
-      \texttt{comp.text.tex}.)
-    \end{enumerate}
-  \item {}
-    \begin{enumerate}
-    \item If the Current Maintainer is reachable and agrees to pass
-      maintenance of the Work to you, then this takes effect
-      immediately upon announcement.
-     
-    \item\label{LPPL:item:announce} If the Current Maintainer is not
-      reachable and the Copyright Holder agrees that maintenance of
-      the Work be passed to you, then this takes effect immediately
-      upon announcement.
-    \end{enumerate}
-  \item\label{LPPL:item:change} If you make an `intention
-    announcement' as described in~\ref{LPPL:item:intention} above and
-    after three months your intention is challenged neither by the
-    Current Maintainer nor by the Copyright Holder nor by other
-    people, then you may arrange for the Work to be changed so as to
-    name you as the (new) Current Maintainer.
-     
-  \item If the previously unreachable Current Maintainer becomes
-    reachable once more within three months of a change completed
-    under the terms of~\ref{LPPL:item:announce}
-    or~\ref{LPPL:item:change}, then that Current Maintainer must
-    become or remain the Current Maintainer upon request provided they
-    then update their communication data within one month.
-  \end{enumerate}
-  A change in the Current Maintainer does not, of itself, alter the
-  fact that the Work is distributed under the \LPPL\ license.
-
-  If you become the Current Maintainer of the Work, you should
-  immediately provide, within the Work, a prominent and unambiguous
-  statement of your status as Current Maintainer.  You should also
-  announce your new status to the same pertinent community as
-  in~\ref{LPPL:item:intention} above.
-
-  \LPPLsubsection{Whether and How to Distribute Works under This License}
-  \label{LPPL:Distribute}
-
-  This section contains important instructions, examples, and
-  recommendations for authors who are considering distributing their
-  works under this license.  These authors are addressed as `you' in
-  this section.
-
-  \LPPLsubsubsection{Choosing This License or Another License}
-  \label{LPPL:Choosing}
-
-  If for any part of your work you want or need to use
-  \emph{distribution} conditions that differ significantly from those
-  in this license, then do not refer to this license anywhere in your
-  work but, instead, distribute your work under a different license.
-  You may use the text of this license as a model for your own
-  license, but your license should not refer to the \LPPL\ or
-  otherwise give the impression that your work is distributed under
-  the \LPPL.
-
-  The document \LPPLdocfile{modguide} in the base \LaTeX\ distribution
-  explains the motivation behind the conditions of this license.  It
-  explains, for example, why distributing \LaTeX\ under the
-  \textsc{gnu} General Public License (\textsc{gpl}) was considered
-  inappropriate.  Even if your work is unrelated to \LaTeX, the
-  discussion in \LPPLdocfile{modguide} may still be relevant, and authors
-  intending to distribute their works under any license are encouraged
-  to read it.
-
-  \LPPLsubsubsection{A Recommendation on Modification Without Distribution}
-  \label{LPPL:WithoutDistribution}
-
-  It is wise never to modify a component of the Work, even for your
-  own personal use, without also meeting the above conditions for
-  distributing the modified component.  While you might intend that
-  such modifications will never be distributed, often this will happen
-  by accident -- you may forget that you have modified that component;
-  or it may not occur to you when allowing others to access the
-  modified version that you are thus distributing it and violating the
-  conditions of this license in ways that could have legal
-  implications and, worse, cause problems for the community.  It is
-  therefore usually in your best interest to keep your copy of the
-  Work identical with the public one.  Many works provide ways to
-  control the behavior of that work without altering any of its
-  licensed components.
-
-  \LPPLsubsubsection{How to Use This License}
-  \label{LPPL:HowTo}
-
-  To use this license, place in each of the components of your work
-  both an explicit copyright notice including your name and the year
-  the work was authored and/or last substantially modified.  Include
-  also a statement that the distribution and/or modification of that
-  component is constrained by the conditions in this license.
-
-  Here is an example of such a notice and statement:
-\begin{verbatim}
-  %% pig.dtx
-  %% Copyright 2005 M. Y. Name
-  %
-  % This work may be distributed and/or modified under the
-  % conditions of the LaTeX Project Public License, either version 1.3
-  % of this license or (at your option) any later version.
-  % The latest version of this license is in
-  %   https://www.latex-project.org/lppl.txt
-  % and version 1.3 or later is part of all distributions of LaTeX
-  % version 2005/12/01 or later.
-  %
-  % This work has the LPPL maintenance status `maintained'.
-  % 
-  % The Current Maintainer of this work is M. Y. Name.
-  %
-  % This work consists of the files pig.dtx and pig.ins
-  % and the derived file pig.sty.
-\end{verbatim}
-  
-  Given such a notice and statement in a file, the conditions given in
-  this license document would apply, with the `Work' referring to the
-  three files `\LPPLfile{pig.dtx}', `\LPPLfile{pig.ins}', and
-  `\LPPLfile{pig.sty}' (the last being generated from
-  `\LPPLfile{pig.dtx}' using `\LPPLfile{pig.ins}'), the `Base
-  Interpreter' referring to any `\LaTeX-Format', and both `Copyright
-  Holder' and `Current Maintainer' referring to the person `M. Y.
-  Name'.
-
-  If you do not want the Maintenance section of \LPPL\ to apply to
-  your Work, change `maintained' above into `author-maintained'.
-  However, we recommend that you use `maintained' as the Maintenance
-  section was added in order to ensure that your Work remains useful
-  to the community even when you can no longer maintain and support it
-  yourself.
-
-  \LPPLsubsubsection{Derived Works That Are Not Replacements}
-  \label{LPPL:NotReplacements}
-
-  Several clauses of the \LPPL\ specify means to provide reliability
-  and stability for the user community. They therefore concern
-  themselves with the case that a Derived Work is intended to be used
-  as a (compatible or incompatible) replacement of the original
-  Work. If this is not the case (e.g., if a few lines of code are
-  reused for a completely different task), then clauses
-  \ref{LPPL:item:changelog} and \ref{LPPL:item:unmodifiedcopy}
-  shall not apply.
-
-  \LPPLsubsubsection{Important Recommendations}
-  \label{LPPL:Recommendations}
-
-  \LPPLparagraph{Defining What Constitutes the Work}
-
-  The \LPPL\ requires that distributions of the Work contain all the
-  files of the Work.  It is therefore important that you provide a way
-  for the licensee to determine which files constitute the Work.  This
-  could, for example, be achieved by explicitly listing all the files
-  of the Work near the copyright notice of each file or by using a
-  line such as:
-\begin{verbatim}
-    % This work consists of all files listed in manifest.txt.
-\end{verbatim}
-  in that place.  In the absence of an unequivocal list it might be
-  impossible for the licensee to determine what is considered by you
-  to comprise the Work and, in such a case, the licensee would be
-  entitled to make reasonable conjectures as to which files comprise
-  the Work.
-
-\end{LPPLicense}

+

+
+
+\section{\LaTeX\texttt{-dev} formats now available}
+
+
+We know that many of you, especially developers and maintainers of
+important packages, have a strong interest in a stable \LaTeX{}
+environment.
+
+In order to keep \LaTeX{} very stable for users whilst allowing for
+further development to continue, we now have a development branch of
+\LaTeX{} on GitHub containing development code for the upcoming
+release. When this code is ready for wider consumption and testing, we
+generate a pre-release of \LaTeX{} from this development branch and make
+it available on \CTAN.
+
+For users of the \TL{} and \MiKTeX{} distributions it is therefore now
+straightforward to test their documents and code against the upcoming
+\LaTeX{} release with ease, simply by selecting a different program name
+(when using the command line) or by selecting a menu entry (after
+setting it up; see below).
+
+If you do this then the latest version of the \LaTeX{} development format
+will be used to process your document, allowing you to test the
+upcoming release with your own documents and packages. For example, if
+you run
+\begin{verbatim}
+  pdflatex-dev myfile
+\end{verbatim}
+then you will be greeted on the screen with something like \texttt{LaTeX2e
+  <2019-10-01> pre-release-2} (identifying the pre-release format)
+instead of the normal \texttt{LaTeX2e <2018-12-01>}. In this
+pre-release you will find the latest new features that we have
+developed. 
+
+\subsection{Our hopes}
+
+We don’t expect everybody to start using the development formats to
+participate in testing, but we hope that people with a strong interest
+in a stable \LaTeX{} environment (especially developers and maintainers
+of important packages) will use the new facilities and help us to
+ensure that future public releases of \LaTeX{} do not (as has happened in
+the past) require some immediate patches because of issues that were
+not identified by our internal regression test suite or by other
+testing
+we do.
+
+Any issue identified when using the development format should
+preferably be logged as an issue on GitHub, following the procedure
+outlined on our website at \url{https://www.latex-project.org/bugs/}
+including the use of the \pkg{latexbug} package as described.
+
+Our bug reporting process normally states that issues involving
+third-party software are out of scope as we can’t correct external
+packages; see~\cite{30:Mittelbach:TB39-1}. However, in the particular
+case of the development format showing an incompatibility with a
+third-party package, it is fine to open an issue with us (in addition,
+please, to informing the maintainer of that package) so that we know
+about the problem and can jointly work on resolving it.
+
+\subsection{Details please \ldots}
+
+More details and some background information about the concepts and
+the process are available in an upcoming \textsl{TUGboat} article: \enquote{The
+  \LaTeX{} release workflow and the \LaTeX{} dev
+  formats}~\cite{devformat}.
+
+\subsection{Setting up menu items}
+
+While the command line call works out of the box if you have a recent  
+\TL{} or \MiKTeX{} installation, its use within an integrated
+editing environment doesn’t at this point in time (maybe the
+developers of these editors will include it in the future). However,
+it is normally fairly simple to enable it as most (or even all?)\ of
+them provide simple ways to call your own setup. How this works in
+detail depends very much on the environment you use, so we can’t give
+much help here.
+
+But as an example: to provide an additional menu entry for
+\texttt{XeLaTeX-dev} on a MacBook all that is necessary is to copy
+the file \texttt{XeLaTeX.engine} to \texttt{XeLaTeX-dev.engine} and change the
+call from \texttt{xelatex} to \texttt{xelatex-dev} inside.
+
+
+
+
+\section{Improving Unicode handling in \pdfTeX{}}
+
+Perhaps the most important improvement in this release is
+even
+better support for \acro{utf}-8 characters when using \pdfTeX{}.\footnote{The
+  Japanese engines e-p\TeX{} and e-up\TeX{} can't use these features
+  yet as they don't support the primitive \cs{ifincsname}. Work is
+  under way to resolve this in the engines.}
+
+When using a \enquote{Unicode engine},  
+any Unicode character (that is not acting as a command, 
+i.e., is not \enquote{active}) 
+can be used as part of the
+\cs{label}/\cs{ref} mechanism or can be displayed in a message or
+written to a file. In 8-bit engines, however, this was severely
+restricted: 
+essentially you had to limit yourself to using
+\acro{ascii} letters, digits and a few punctuation symbols.  With the
+new release, most of these restrictions have been removed and you now
+can write labels such as
+\begin{verbatim}
+  \label{eq:größer}
+\end{verbatim}
+or use accented characters, etc., as part of a \cs{typeout} message.
+The only requirement remaining is that only those \acro{utf}-8 characters
+that are also available for typesetting can be used, i.e., only those
+characters for  
+which adequate font support is loaded. Otherwise you will get an
+error message stating that 
+the 
+particular Unicode character is not set
+up for use with \LaTeX{}.
+
+Note, however, that the restrictions on what characters can be 
+used in the names of commands have not changed. 
+
+What is not possible when using 
+an 8-bit engine such as \pdfTeX{} is to use
+characters other than \acro{ascii} letters as part of a command
+name. This is due to the fact that all other characters in such
+engines are not single character tokens, but in fact consist of a
+sequence of bytes and this is not supported in command names.
+
+\section{Improving file name handling in \pdfTeX{}}
+
+A related change is that file names used as part of \cs{input},
+\cs{includegraphics}, etc., commands 
+can now contain any 
+Unicode characters allowed by the file system in use,  
+including spaces. 
+In this case, 
+ even characters that can't be typeset 
+(due to lack of font support) can be used.
+
+
+\section{Improving the \env{filecontents} environment}
+
+The \env{filecontents} environment now supports an optional argument
+in which you can specify that it is allowed to \option{overwrite} an
+already existing file;  
+ by default nothing is written if a file with the given name 
+exists anywhere in the search tree. An alternative name for this
+option is \texttt{force}.  
+Even then the environment will refuse to write
+to \cs{jobname}\texttt{.tex} to avoid clobbering its own input
+file. However, if you use a different extension on your input file you
+could still overwrite it (there is no way to test for that).
+
+There is also an
+option 
+\option{nosearch}, 
+which specifies that only the current directory is
+examined for an existing file, not the whole \TeX{} inputs tree. 
+This is useful if you want to write a
+local copy of a standard system file.
+Finally, \option{noheader} prevents writing a preamble to the file 
+(this  
+is the same as using the star form of the environment).
+
+Another change is that this 
+environment is 
+now allowed anywhere in the document, 
+which means
+it provides everything (and more) of what the now obsolete 
+\pkg{filecontents} package provided.
+
+
+
+\section{Making more user commands robust}
+
+In the early days of \LaTeX{} many commands were fragile, i.e., they
+needed \cs{protect} in front of them when used in places such as
+section headings and other \enquote{moving arguments}, etc. 
+In \LaTeXe{} many of these commands were made robust,  
+but still a fairly large number remained unnecessarily fragile.
+
+In this release of \LaTeX{} we have now 
+made a lot more commands robust.
+There is a very small collection of commands that must stay fragile  
+because their expansion (maybe partially) at just the right time is critical.
+Yet others are unlikely to ever be needed in a \enquote{moving argument}.
+
+Doing this for \cs{begin} and \cs{end} was rather tricky as the
+standard mechanism with \cs{DeclareRobustCommand} doesn't work here,
+at least not for \cs{end} as that needs to expand during typesetting
+without generating a \cs{relax} (from the \cs{protect}). Such a token
+would start a new row in table environments, such as \texttt{tabular},
+etc. Furthermore, some packages try to look into the definition of
+\cs{end} by expanding it several times. Thus expansion with
+\cs{expandafter} had to produce exactly the same result as before. But
+in the end we overcame that hurdle too, so now environments are
+automatically robust if used in places like headings or
+\verb=\typeout= and so forth.
+
+%%CCC do we need to say something about possible problems if other packages 
+%%   or documents have redefined commands whose robustness has changed?
+
+What hasn't been tackled yet is the redefinitions in \pkg{amsmath}: 
+this package
+redefines a number of basic math constructs
+that are now robust, so that  
+they become fragile again
+once the package is loaded. 
+This area will be addressed in a followup release.

+\section{Other changes to the \LaTeX{} kernel}
+
+\subsection{Guard against \cs{unskip} in tabular cells}
+
+If a \env{tabular} or \env{array} cell started with a 
+command that started with an 
+\cs{unskip} 
+then centering the column broke 
+ because the stretching glue   
+ on the left got removed. The fix for this was to add 
+ a minuscule, and hence unnoticeable, additional space after the stretching space: 
+removing this extra space causes no problems.
+
+This change was also applied in the \pkg{array} package.
+
+\githubissue{102}
+
+
+\subsection{Fix Unicode table data}  
+
+\texttt{U+012F} which is \enquote{i with ogonek} produced a
+\enquote{dotless i with ogonek} by mistake. This has been corrected.
+
+\githubissue{122}
+
+The Unicode slots \texttt{27E8} and \texttt{27E9} have been mapped to
+\cs{textlangle} and \cs{textrangle} which is the recommended mapping.
+In the past they raised a
+\\
+\LaTeX{} error.
+%
+\githubissue{110}
+
+When doing cut-and-paste from other documents or websites, f-ligatures and others ligatures
+might end up as 
+single Unicode characters in your file. In the past those got rejected by \LaTeX{}.
+ We 
+ now define those Unicode slots and map them back to the sequence of
+ individual characters constituting the ligature.
+If supported by the current font
+(which is normally the case) they
+are then reconstructed as ligatures and thus get typeset 
+as desired. 
+Otherwise they will come out as individual characters which
+is still better than an error message.
+
+\githubissue{154}
+
+
+\subsection{Improve \cs{InputIfFileExists}'s handling of file names}
+
+In rare circumstances it was possible that \cs{InputIfFileExists}
+would work incorrectly, e.g., a construction such as
+\begin{verbatim}
+\InputIfFileExists{foo}{\input{bar}}{}
+\end{verbatim}
+would not load the files \texttt{foo.tex} and \texttt{bar.tex} but
+would load \texttt{bar.tex} twice. This has been corrected.
+
+\githubissue{109}
+
+
+\subsection{Improve interface for cross-references}
+
+%%CCC  should be 'provide' as they still exist. FMi - no they no longer do that
+The packages \pkg{fncylab} and \pkg{varioref} provided
+a slightly
+improved definition of \cs{refstepcounter} which allowed
+the internal
+\cs{p@..} commands to receive the counter value as an argument, 
+instead of 
+acting as a simple prefix. This supports 
+more complex 
+formatting of the value in the reference. 
+
+
+These packages also provided
+the command \cs{labelformat} to help in the specification of
+such formatting in an easy way.  For
+example, \verb=\labelformat{equation}{eq.~(#1)}= specifies that 
+references to equations
+automatically come out as
+\enquote{eq.~(5)} or similar. As such a \cs{labelformat} declaration
+means a \cs{ref} command can no
+longer be successfully used at the start of a sentence, the packages also
+provided \cs{Ref} for such scenarios.
+
+Both of these commands, \cs{labelformat} and \cs{Ref},
+are now removed from the packages and instead made available in 
+the kernel so there is no 
+need to load additional packages.
+
+
+
+
+\subsection{Improve wording of a warning message}
+
+The kernel now says \enquote{Trying to load \ldots}
+instead of \enquote{Try loading \ldots} in one of its informal
+messages to match style of similar messages.
+%
+\githubissue{107}
+
+
+\subsection{Avoid bad side-effects of \cs{DeclareErrorFont}} 
+
+As a side effect of setting up the error font for \acro{nfss}, this
+declaration also changed the current font size back to 10pt.
+In most
+circumstances that doesn't matter, because that declaration was meant
+to be used only during the format generation and not during 
+a \LaTeX{} run. 
+However, it has turned out to  be
+used by some developers in other places
+(incorrectly in fact:
+e.g., inside some \texttt{.fd} files) where 
+resetting the size causes 
+havoc
+seemingly at random.
+The command has now changed to not produce such side effects.
+
+\gnatsissue{latex}{4399}
+
+
+
+\subsection{\pkg{nfssfont}: Make font table generation the default action}
+
+With the small file \texttt{nfssfont.tex} it is possible to produce
+font tables and other font tests 
+in the style set up by Don Knuth. 
+In nearly all cases 
+a font table is wanted, 
+so this action has been made the default. 
+Now one can simply hit enter
+instead of having to write \verb=\table\bye=.
+
+
+\subsection{\pkg{trace}: Add package support in the kernel}
+
+The \pkg{trace} package implements the commands \cs{traceon}
+and \cs{traceoff} that work like 
+\cs{tracingall} but skip
+certain code blocks that produce a lot of tracing output.
+%%CCC   being of no interest to anyone!! -- FMi I love your encouragement
+This is useful when debugging, to suppress uninteresting tracing 
+from, for example, loading a font. 
+Code blocks that should not be traced
+need to be surrounded by the commands
+\cs{conditionally@traceoff} and \cs{conditionally@traceon}.
+
+The \LaTeX{} kernel now provides dummy definitions for these two
+commands so that package writers can use them in their packages
+regardless of \pkg{trace} being loaded or not.
+
+
+
+        
+\section{Changes to packages in the \pkg{tools} category}
+
+\subsection{\pkg{array}: Warn if primitive column specifiers are overwritten}
+
+With \cs{newcolumntype} it is possible to define your own column
+specifiers for a \texttt{tabular} preamble; it is also possible to
+change existing ones. However, doing that for a primitive column
+specifier, such as \texttt{c}, is seldom a good idea, since then its
+functionality becomes unavailable. 
+The package was therefore supposed
+to warn the user in this case, but due to a missing \cs{expandafter}
+in the code it never did---now it does.
+%
+\githubissue{148}
+
+
+\subsection{\pkg{multicol}: Introduce \texttt{minrows} counter for balancing}
+
+When there are only a few lines of text on a page at the end of a
+\env{multicols} environment, 
+balancing the columns often looks rather odd: such as 
+three columns each containing a single line. The balancing behavior
+can now be controlled through the counter \texttt{minrows} 
+(default is~1) which specifies that,  
+after balancing, there must be at least that many lines in the first column. 
+Thus, if you set \texttt{minrows}
+to \texttt{2} then you 
+would get a
+distribution of \texttt{2+1+0} lines and if set 
+to three, the result
+would be 
+\texttt{3+0+0} instead of the default \texttt{1+1+1}. 
+
+What is most appropriate really depends on the circumstances, but this
+now gives you the tools to make local or global adjustments.
+
+
+\subsection{\pkg{varioref}: Better support for \pkg{cleveref}}
+
+The \pkg{varioref} package has been internally updated to provide
+better interfaces for packages such as \pkg{hyperref} and
+\pkg{cleveref}.
+
+It also  
+has a new package option \option{nospace} that stops
+\pkg{varioref} from meddling with space in front of
+its commands. The
+original behavior was always somewhat problematical and it is
+suggested that 
+all new documents 
+use this option (which
+should really have been the default).
+
+Support was also added for the Arabic language through the option
+\option{arabic}.
+
+
+
+        
+\subsection[\pkg{xr}: Support citations to bibliographies in\\ external documents]
+{\pkg{xr}: Support citations to bibliographies in external documents}
+
+The \pkg{xr} package can be used to cross-reference an external \LaTeX{} 
+document. 
+This means that even when a work is split over different documents (that
+need to be processed separately), \cs{ref} or \cs{pageref} can use labels from 
+any document, creating links between them. This facility has now been extended 
+so that \cs{cite} commands and
+their cousins can now also reference bibliographies in external
+documents; this feature was first provided in the package
+\pkg{xcite} by Enrico Gregorio.
+
+Note that for technical reasons \pkg{xr} doesn't work with
+\pkg{hyperref}. Use \pkg{xr-hyper} instead if you need the latter
+package.
+
+
+\section{Changes to packages in the \pkg{amsmath} category}
+
+\subsection{\pkg{amsmath}: Introduce \cs{overunderset} command}
+
+The \pkg{amsmath} package has always offered 
+the commands \cs{overset} and
+\cs{underset} to produce binary operators with something set above or
+below. But sometimes one needs to put something above and something below: 
+The newly added \cs{overunderset} makes this
+easily possible.
+
+
+
+\section{Documentation updates}
+
+There are a number of
+%small
+documentation updates in files 
+on the documentation page of the project website~\cite{30:site-doc}.
+
+\subsection{Highlighting the standard \texorpdfstring{\acro{nfss}}{NFSS} codes for series} 
+
+The \emph{Font Selection Guide}~\cite{fntguide} has been
+updated to strongly recommend that the standard codes should be used
+when providing font support.  The reason for this recommendation is explained here.
+
+
+The font selection scheme uses a number of standard codes for
+\cs{fontseries} and \cs{fontshape} to ensure that different fonts are
+comparable, e.g., that you get a \enquote{light} weight if you specify
+\texttt{l} and \enquote{extra bold} when you write \texttt{eb},
+etc. Over the years people came up with a number of other creative
+short codes like \texttt{k}, \texttt{j}, \texttt{t} and others with
+the result that changing a font family required different codes and
+thus prevented users from easily mixing and matching different
+families. 
+Some work has been undertaken to get back to a coherent scheme and
+all the font families supported through the program \texttt{autoinst}
+are now producing the standard codes again. 
+
+
+\subsection{\LaTeX{} \texttt{base} and \texttt{doc} distribution reunited}
+      
+For a long time the \LaTeX{} distribution available from \CTAN{} was
+split into several parts to allow them to be uploaded or downloaded
+separately. As this is these days more confusing than helpful we have
+recombined the base part with the documentation part (as both are
+anyway always updated together). Thus the package \texttt{latex-doc}
+is no longer separately available from \CTAN{} but contained in the
+\texttt{latex-base} distribution.

-\title{Errata to the Second Edition of the \LaTeX\ Manual}
-\author{Leslie Lamport}
-\date{\moddate}
-
-\begin{document}
-\maketitle
-
-\noindent These are all the errors and omissions to the manual,
-\LaTeX: {\em A Document Preparation System}, second edition, published
-by Addison-Wesley, reported as of \moddate.  Positions in the book are
-indicated by page and line number, where the top line of a page is
-number 1 and the bottom line is number $-1$.  A running head and a
-page number are not considered to be lines, but all other lines are.
-Please report any additional errors to The \LaTeX\ Project at
-\texttt{www.latex-project.org/bugs/}\,.

- \reportedby{Ellen Gilkerson}{9 Aug 1994}
-
-\erratum{page 108, lines 7 and 10}

-\reportedby{Jerome Breitenbach}{14 Dec 1995}
-
-\erratum{page 182} 
-The dimensions
-\verb|\pageheight| and \verb|\pagewidth|

-
-Insert the following text right after ``\texttt{l}, and \texttt{r}.''
-\begin{quote}
-If the part of the environment's \emph{cols} argument being replaced
-immediately follows an \texttt{@} expression, then the \emph{item}
-will be preceded by a normal intercolumn space unless the
-\verb|\multicolumn| command's \emph{col} argument begins with an
-\texttt{@} expression.  In particular, beginning the \emph{col}
-argument with \verb|@{}| will suppress that space.

-will be made between all those with the largest number of findings).
-A person can receive at most one prize, ever; errors found by any of
-the authors do not count.

-Each prize is a free choice of any single computing book found on the
-AW Professional web site \texttt{http://www.awprofessional.com} (that
-is, no boxed sets or multiple volume offers).
-
-
-As usual, the authors and publisher reserve the right to make various
-decisions such as whether a reported feature is an error for
-competitive purposes or whether similar features count as a single or
-multiple errors.  --- 
-Good luck!

-   Due to the printing process there may be small alignment problems

-Poor Maxwell's equations! No doubt there are mathematical
- physicists or physical mathematicians that write Maxwell's equations that way.
- This is a good example for showing some capabilities of the
- \textsf{amsmath} package and its possible extensions by means of the
- \comando{\newenvironment} command, but it is an example where all possible ISO
- rules are violated! Physical equations deal with quantities, not with
- mathematical variables; and quantities have dimensions; as such they have to
- comply with the rules established by the Sisth\`{e}me International (SI) and the
- various obsolete ``cgm'' systems are officially deprecated; the partial
- derivative sign $\partial$ has exactly that meaning and it cannot substitute
- the ``nabla'' $\nabla$ sign;  finally the $j$ symbol probably indicates the
- current density, but in an equation that does not comply with the ISO rules it
- might indicate the imaginary unit (which, on the opposite, is prescribed to be
- typeset in roman or upright shape as well as $\pi$); treating with vectorial
- quantities these should be well marked either with a vector math accent or
- must be set in bold italic; with variables depending from four quantities the
- apex for indicating the derivative is not univocal for specifying the quantity
- with respect to which the derivative is taken. I repeat: the example is good
- for describing the math extension capabilities but it could induce the casual
- reader to believe that this is the correct form for writing down the Maxwell's
- equations; unfortunately it is not.

-A remark on {\sf devnag} package:-- Originally developed by Frans
-Velthuis in 1991, it was upgraded for use with \LaTeXe{} (made
-NFSS-complaint), and maintained by a team consisting of Dominik
-Wujastyk, John Smith, Anshuman Pandey, Fran\c{c}ois Patte, and
-Zden\v{e}k Wagner. Very recently, the project has
-been handed over to TUGIndia, for further development,

-   With parenthesized arguments, commas are part of the syntax;

-   Since xindy ignores all macros, it has no problems at all with

-   Substituted this paragraph with:
-
-   ``\texttt{texindy} ignores unknown
-   \TeX{} commands by default under the assumption that they do not
-   produce text. It also knows about typical text-producing commands
-   like \verb=\LaTeX= and \verb=\BibTeX= and handles them correctly.
-   If you have your own command definition that produces text, or if you
-   use one supplied by a package, then the entry is sorted
-   incorrectly. You will either need to specify an explicit sort key
-   in your index entry, as in \verb=\index{prog@\Prog}=, or write a
-   \texttt{xindy} style file with a merge rule, as explained in
-   Section~11.3.4.
-
-   Be aware that producing index entries in arguments of commands has
-   its own pitfalls, e.g., in 
-   \verb=\command{Properties of \Prog\index{\Prog}}=.  
-   Then \LaTeX{} commands might be expanded
-   before they are written to the \texttt{idx} file and the placement

-## README for the  Standard LaTeX `Graphics` bundle
+The LaTeX `graphics` bundle
+===========================
 
-This bundle consists of LaTeX2e packages written and supported by
-members of the LaTeX3 Project Team.
+Release 2019-10-01
 
-It is a collection of LaTeX packages for:
-- producing colour
-- including graphics (eg PostScript) files 
-- rotation and scaling of text
-in LaTeX documents.
+Overview
+--------
 
+This bundle consists of packages supporting basic color, graphics and text
+manipulation operations in LaTeX. The packages provided here are
 
+- `color`: Core color support
+- `graphics`: The original LaTeX graphics inclusion interface
+- `graphicx`: Extended interface for graphics inclusion
+- `lscape`: Production of landscape pages
+- `keyval`: Core key-value support for LaTeX
+- `rotating`: Support for rotating material
+- `trig`: Support for fast trigonometric calculations in TeX
 
-### THIS DIRECTORY CONTAINS 
+plus the legacy stub `epsfig` (now subsumed into `graphics`).
 
-#### Support files

-
-
-### TO UNPACK THE PACKAGES
-
-     latex graphics.ins
-
-This will produce the `.sty` package files.
-
-Similarly you can run
-
-     latex graphics-drivers.ins
-
-to produce the `.def` driver files.
-
-Not all supported drivers are included in this file as they are
-maintained elsewhere.
-
-
-### USING THE PACKAGES
-
-Move files ending in `.sty` or  `.def`  to a standard TeX input directory.
-
-Make a default option for your site by creating two files `color.cfg` and `graphics.cfg`
-containing (if dvips is your default driver)
-     \ExecuteOptions{dvips}
-
-You may then LaTeX the user guide by running:
-
-     latex grfguide.tex
-

-## README for the `tools` bundle
+The LaTeX `tools` bundle
+========================
 
+Release 2019-10-01
 
-This bundle consists of LaTeX2e packages written and supported by
-members of the LaTeX3 Project Team.
+Overview
+--------
 
-The documented source code of each package is in a file with extension
-`.dtx`.  Running LaTeX on the file `tools.ins` will produce all the
-package files, and some associated files.
+This bundle consists of packages providing a range of basic tools for
+LaTeX users. It is a required part of a LaTeX installation.
 
-So you should first process `tools.ins`:
+Installation
+------------
 
-    latex tools.ins
+We no longer distribute installation instructions for the various TeX
+implementations. All modern TeX systems include `tools` as-standard, and end
+users should in general use the release versions supplied in this way.
 
-The files with extensions `.sty` and `.tex` (including a file whose
-name is just `.tex`) should then be moved to a directory on LaTeX's
-standard input path.
+Release distribution is carried out only through the CTAN archives.
 
-Documentation for the individual packages may then be obtained by
-running LaTeX on the `.dtx` files.
-
-For example:
-
-    latex array.dtx
-
-will produce the file `array.pdf`, documenting the array package.
-
-
-The file `manifest.txt` contains a list of the main files in the
-distribution together with a one-or-two line summary of each package.
-
-
-### Copyright
-
-Copyright is maintained on each of these packages by the author(s)
-of the package.

-and version 1.3c or later is part of all distributions of LaTeX 
-version 2005/12/01 or later.
-
-The list of all files belonging to the Tools Bundle is
-given in the file `manifest.txt`.
-
-Commercial users of the `multicol` package are asked to read the
-notice at the head of the file multicol.dtx.
-
-The use of these files is otherwise unrestricted.

-README for the `tools' bundle
-=============================
-
-This `bundle' consists of LaTeX2e packages written and supported by
-members of the LaTeX3 Project Team.
-
-The documented source code of each package is in a file with extension
-`.dtx'.  Running LaTeX on the file tools.ins will produce all the
-package files, and some associated files.
-
-So you should first process tools.ins:
-
-  latex tools.ins
-
-The files with extensions `.sty' and `.tex' (including a file whose
-name is just `.tex') should then be moved to a directory on LaTeX's
-standard input path.
-
-See the Note at the end of this file if you have problems processing
-the tools.ins file.
-
-Documentation for the individual packages may then be obtained by
-running LaTeX on the `.dtx' files.
-
-For example:
-
-  latex array.dtx
-
-will produce the file array.dvi, documenting the array package.
-
-
-The file manifest.txt contains a list of the main files in the
-distribution together with a one-or-two line summary of each package.
-
-
-Copyright
-=========
-Copyright is maintained on each of these packages by the author(s)
-of the package. 
-
-
-Distribution Conditions
-=======================
-
-All the files in this bundle may be distributed under the conditions
-of the LaTeX Project Public License, either version 1.1 of this
-license or (at your option) any later version.  The latest version of
-this license is in
-   https://www.latex-project.org/lppl.txt
-and version 1.1 or later is part of all distributions of LaTeX 
-version 1999/06/01 or later.
-
-The list of all files belonging to the `Tools Bundle' is
-given in the file `manifest.txt'.
-
-Commercial users of the multicol package are asked to read the
-notice at the head of the file multicol.dtx.
-
-The use of these files is otherwise unrestricted.
-
-
-Reporting Bugs
-==============
-
-If you wish to report a problem or bug in any of these packages, use
-the latexbug.tex program that comes with the standard LaTeX
-distribution.  Please ensure that you enter `tools' category when
-prompted with a menu of categories, so that the message will be
-automatically forwarded to the appropriate part of our database.
-
-When reporting bugs, please produce a small test file that shows the
-problem, and ensure that you are using the current version of the
-package, and of the base LaTeX software.

+% (this is actually the same as using the star form of the environment).
+%
+% The environment is now allowed anywhere in the document, but to ensure

+%
+%    The \texttt{trace} package implements the commands \cs{traceon}
+%    and \cs{traceoff} that work similar to \cs{tracingall} but skip
+%    certain code blocks that produce a lot of tracing output being of no
+%    interest during debugging (for example loading a font).
+%    Code blocks that should be hidden during tracing need
+%    to be surrounded by the macros \cs{conditionally@traceoff}
+%    and \cs{contionally@traceon}.
+%
+%    For the kernel code the \texttt{trace} package then redefines a
+%    number of macros to  include this tracing support.
+%
+%    However, in order to allow any macro package to react to
+%    \cs{traceon} we also provide dummy definitions for the two
+%    commands in the kernel so that they can be used by external
+%    packages without the
+%    need to distinguish between \texttt{trace} being loaded or not.

+%   File name handling is done by generating a csname from the
+%   provided file name (which means that UTF-8 octets gets turned into
+%   strings as this is what happens if they appear in a csname due to
+%   the code in \texttt{utf8.def}). By setting \cs{escapchar} to
+%   \texttt{-1} we ensure that we don't get a backslash in front. As a
+%   result we end up with all characters as catcode 12 (plus
+%   spaces). We then sometimes add quotes around the contruct
+%   (removing any existing inner quotes. Somes we only remove the
+%   quotes if they have been supplied by the user. There is clearly
+%   some room for improvement.
+%
+%   A side effect of the new code is that we will see quotes around
+%   file name displays where there haven't been any before.

 %  \begin{macro}{\end}
+%    While \cs{begin} was made robust simply by using
+%    \cs{DeclareRobustCommand} we need to be a bit more subtle with
+%    \cs{end} as there are packages out there that try to look into
+%    the top-level contents of \verb=\end{foo}= (that is at the expansion
+%    of \verb=\endfoo=) to see if it contains certain macros. This is
+%    done by hitting \verb=\end{foo}=  with three \cs{expandafter}s,
+%    the first to get
+%\begin{verbatim}
+%  \csname endfoo\endcsname       \@checkend{foo}% etc.
+%\end{verbatim}
+%    the second to expand the \cs{csname}, i.e., to get to
+%\begin{verbatim}
+%  \endfoo                        \@checkend{foo}% etc.
+%\end{verbatim}
+%    and the third to finally get to the top-level content of
+%    \verb=\endfoo=, i.e.
+%\begin{verbatim}
+%  <top-level content of \endfoo> \@checkend{foo}% etc.
+%\end{verbatim}
+%    Therefore a robust replacement should produce the same results
+%    after three expansions (there first is obviously different).
+%
+%    Basically the definition of \cs{end} should either produce
+%    \verb*=\protect\end = (when not doing typesetting) or it should
+%    produce \verb*=\end = (without the \cs{protect}) when doing typesetting.
+%    Furthermore, it should (when in typesetting mode) show exactly the
+%    same result as
+%    \verb*=\end = (which is the original fragile definition
+%    of \cs{end}) when you expand either of them twice, i.e.,
+%\begin{verbatim}
+%  \endfoo                        \@checkend{foo}% etc.
+%\end{verbatim}
+%    That is achieved with the code below (which is worth studying
+%    carefully).
+%
+%    There is some trickery involved here: in particular we use
+%    \cs{romannumeral} to change a single expansion into three
+%    successive expansions in one go. That primitive expands until it
+%    has scanned a number (0 in this case, so it doesn't produce any
+%    output) and so it allows us to place arbitrary many
+%    \cs{expandafter}s inside that are all going to be executed when
+%    \cs{romannumeral} is hit by a single \cs{expandafter}.

+% \DescribeMacro\labelformat
+% A reference via |\ref| produces by default the data associated with
+% the corresponding |\label| command (typically a number); any
+% additional formatting has to be provided by the user. If, for
+% example, references to equations are always to be typeset as
+% ``equation (\textit{number})'', one has to code
+% ``\verb=equation (\ref{=\textit{key}\verb=})=''.  With |\labelformat|
+% there is a possibility to generate such
+% frills automatically without resorting to low-level coding.
+% The command takes two arguments: the first is
+% the name of a counter and the second is its representation when
+% referenced. This means that for a successful usage, one has to know
+% the counter name being used for generating the label, though in
+% practice this should not pose a problem. The current counter number
+% is picked up as an argument.
+% Here are two examples:
+%\begin{verbatim}
+%  \labelformat{section}{section~#1}
+%  \labelformat{equation}{equation~(#1)}}
+%\end{verbatim}
+%
+% \DescribeMacro\Ref
+% A side effect of using |\labelformat| is that, depending on the
+% defined formatting, it becomes impossible to use |\ref| at the
+% beginning of a sentence (if its replacement text starts with a
+% lowercase letter). To overcome this problem we
+% introduce the command |\Ref| that behave like
+% |\ref| except that it uppercases the first token
+% of the generated string.
+%
+
+% To make |\Ref| work properly the very first token in the second
+% argument of |\labelformat| has to be a simple \textsc{ascii} or
+% UTF-8 letter, otherwise the capitalization will fail or worse, you
+% will end up with some error messages. If you actually need something
+% more complicated in this place (e.g., an accented letter not written
+% as a UTF-8 character) you have to explicitly surround it with
+% braces, to identify the part that needs to be capitalized. For
+% example, for figure references in the Hungarian language you might
+% want to write |\labelformat{figure}{{\'a}bra~\thefigure}| or use
+% |\labelformat{figure}{ábra~\thefigure}| which avoids the brace
+% problem.

+%    The trick is to ensure that |\csname the#1\endcsname| is turned
+%    into a single token before |\p@...| is expanded further. This
+%    way, if the |\p@...| command is a macro with one argument it will
+%    receive |\the...|. With the original kernel code (i.e., without the
+%    |\expandafter|) it will instead pick up |\csname| which would be
+%    disastrous.
+%    
+%    Using |\expandafter| instead of braces delimiting the argument is
+%    better because, assuming that the |\p@...| command is not defined
+%    as a macro with one argument, the braces will stay and prohibit
+%    kerning that might otherwise happen between the glyphs generated
+%    by |\the...| and surrounding glyphs.
+%
+%  \changes{v1.1l}{2019/08/22}{Allow \cs{p@...} to have an
+%          argument}
+%    \begin{macrocode}

+%  \begin{macro}{\labelformat}
+%    A shortcut to set the |\p@...| macro for a counter. It will pick
+%    up the counter representation as an argument so that it can be
+%    specially formatted.
+%  \changes{v1.1l}{2019/08/22}{Commanded moved from \texttt{varioref.sty}}

+\def\labelformat#1{\expandafter\def\csname p@#1\endcsname##1}
 %    \end{macrocode}
 %  \end{macro}
 %
+%  \begin{macro}{\Ref}
+%    This macro expands the result of |\ref| and then uppercases the
+%    first token. Only useful if the label was generated via
+%    |\labelformat| and contains some lower case letter at its start. If
+%    the label starts with a complicated construct (e.g., an accented
+%    letter that is provided via a command, e.g., \verb=\"a= instead
+%     of a UTF-8 character like ä) one has to surround everything that
+%    needs uppercasing in
+%    a brace group in the definition of |\labelformat|.\footnote{There
+%    is one problem with this approach: the braces are kept in a
+%    normal \texttt{\textbackslash ref} which might spoil kerning.
+%    Perhaps one day this needs redoing.}

-% \subsection{An extension of counter referencing}
 %
 %
-% At the moment a reference to a counter |foo| will generate the
-% equivalent of |\p@foo\thefoo| although not quite in this form.  For
-% some applications it would be nice of one could have |\thefoo| being
-% an argument to |\p@foo| to be able to put material before and after
-% the number generated by |\thefoo|. This can be easily achieved with
-% a small change to one of the kernel commands as follows:

-% We have refrained from making this change in the kernel code

-%
-% Instead we suggest that people who are interested in using this

 %    A UTF-8 char (that is not actually a 7-bit char, i.e.~a single
 %    octet) is parsed as follows: each starting octet is an active
 %    \TeX{} character token; each of these is defined below to be a
 %    macro with one to three arguments nominally (depending on the
 %    starting octet). It calls one of |\UTFviii@two@octets|,
 %    |\UTFviii@three@octets|, or |\UTFviii@four@octets| which then
-%    actually picks up the argument(s).
+%    actually picks up the remaining octets as the argument(s).
+%
+%    \begin{itemize}
+%  \item When typesetting we pick up the necessary number of additional
+%    octets, check if they form a command that \LaTeX{} knows about
+%    (via \cs{csname} \texttt{u8:}\cs{string}
+%     \verb=#1=\cs{string} \verb=#2...=\cs{endcsname}) and if so use that
+%    for typesetting.  \cs{string} is needed as the octets may (all?) be
+%    active and we want the literal values in the name.
+%
+%  \item If the UTF-8 character is going to be part of a label, then it is
+%    essentially becoming part of some csname and with the
+%    test \cs{ifincsname} we can find this out. If so, we render the whole
+%    sequence off octets harmless by using \cs{string} too when the
+%    starting octet executes (\cs{UTF@...@octets@string}).
+%
+%  \item Another possible case is that \cs{protect} has \emph{not} the meaning
+%    of \cs{typeset@protect}. In that case we may do a \cs{write} or we may do
+%    a \cs{protected@edef} or \ldots{}  In all such cases we want to keep the
+%    sequence of octets unchanged, but we can't use \cs{string} this time, since at
+%    least in the case of \cs{protect@edef} the result may later be
+%    typeset after all (in fact that is quite likely) and so at that
+%    point the starting octet needs to be an active character again
+%    (the others could be stringified). So for this case we use \cs{noexpand}
+%    ((\cs{UTF@...s@octets@noexpand}).
+%  \end{itemize}
 %
+% \begin{macro}{\UTFviii@two@octets}
+% \changes{v1.2a}{2018/03/24}{Macros made `\cs{long} for improved error messages}%
+%    Putting that all together the code for a start octet of a two
+%    byte sequence would then look like this:
+%    \begin{macrocode}
+\long\def\UTFviii@two@octets{%
+  \ifincsname
+    \expandafter \UTF@two@octets@string
+  \else
+    \ifx \protect\@typeset@protect \else
+      \expandafter\expandafter\expandafter \UTF@two@octets@noexpand
+    \fi
+  \fi
+  \UTFviii@two@octets@combine
+}
+%    \end{macrocode}
+
+%    \cs{ifcsname} is tested first because that can be true even if we
+%    are otherwise doing typesetting. If this is the case we use
+%    \cs{string} on the whole octet
+%    sequence. \cs{UTF@two@octets@string} not only does this but also
+%    gets rid of the command \cs{UTFviii@two@octets@combine} in the input
+%    stream by picking it up as a first argument and dropping it.
+%
+%     If this is not the case and we are doing typesetting (i.e.,
+%    \cs{protect} is \cs{typeset@protect}), then we execute
+%    \cs{UTFviii@two@octets@combine} which picks up all octets and typesets
+%    the character (or generates an error if it doesn't know how to
+%    typeset it).
+%
+%    However, if we are not doing typesetting, then we execute the
+%    command \cs{UTFviii@two@octets@noexpand} which works like
+%    \cs{UTF@two@octets@string} but uses \cs{noexpand} instead of
+%    \cs{string}. This way the sequence is temporay rendered harmless,
+%    e.g., would display as is or stays put inside a
+%    \cs{protected@edef}. But if the result is later reused the
+%    starting octet is still active and so will be able to construct
+%    the UTF-8 character again.

+%    When doing cut-and-paste from other documents f-ligatures might show
+%    up as Unicode characters. We translate them back to individual
+%    characters so that they get accepted. If supported by the font
+%    (which is normally the case) they are then reconstructed as
+%    ligatures so they come out as desired. Otherwise they will come
+%    out as individual characters which is fine too.

+%    True if the two pages have arabic page numbers are at most off by
+%    one so that |\vpageref| would produce a special string.
+%
+%    This is n some sense a general version of |\vpagerefnearby| for
+%    use in more complex situations. I.e., if you try to determine if
+%    a larger set of references would be close to the current page and
+%    you use each time |\vpagerefnearby| then you generate a lot of
+%    internal labels for the current point. Thus by setting the label
+%    yourself you can save processing time and space. On the other
+%    hand you have to be careful to place the label into the right
+%    place which can be a bit complicated if you look at the
+%    definition of |\vpagerefnearby| that does all this automatically
+%    for you. This is why the current macro is not discussed in the
+%    user interface section as it is really just for package
+%    developers.

+%
+%  \begin{macro}{\labelformat}
+%  \begin{macro}{\Ref}
+%  \begin{macro}{\refstepcounter}
+%    We don't need to define \cs{labelformat} and \cs{Ref} or change the
+%    definition of \cs{refstepcounter} any longer because this is now
+%    done in the \LaTeX{} kernel. However, if this package is used
+%    together with an older kernel, this is not true, so for this
+%    special case we keep the definitions.
+%    \begin{macrocode}
+\ifx\labelformat\@undefined  % assume we are in an older kernel
+  \def\labelformat#1{\expandafter\def\csname p@#1\endcsname##1}
+  \DeclareRobustCommand\Ref[1]{\protected@edef\@tempa{\ref{#1}}%
