-\section{Scheduled \LaTeX\ bug-fix release}
-
-This issue of \LaTeX~News marks the second bug-fix release of
-\LaTeXe\ (standard \LaTeX) since shifting to a new build system in 2009.
-Provided sufficient changes are made, we expect to
-make such releases yearly or every two years, in sync with \TeX\ Live.
-
-
-
-\subsection{Release notes}
-
-This release makes no changes to the core code in the \LaTeXe\ format
-but there are a small number of documentation fixes (not listed
-here). 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}

-\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.

-\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'. However, if you see or hear that a
-package `uses \LaTeX3' then it remains very unlikely (as yet) to mean
-that the package is part of some `new version of \LaTeX'.
-
-News about the development and use of \textsf{expl3} and about other
-developments in the \LaTeX3 code base is reported regularly in the
-\LaTeX3~News series (\url{http://latex-project.org/l3news/}), the most
-recent issue of which was published in March 2014.
