Also the lists of Lua callbacks handled by the callback -allocation mechanism has been updated to match the callbacks defined -in Lua\TeX\ version 0.90. - -These changes have also required updates in \textsf{tools} -and \textsf{amsmath} as described below. - -This is the first release of \LaTeX\ for which the test suite reports -no failures when used with Lua\TeX. - -\section{Documentation checksums} -The \package{doc} package has always provided two mechanisms that were -mainly intended to guard against file truncation or corruption when -files were commonly distributed by email through unreliable mail -gateways: a Character Table of the ASCII character set could be -inserted (and checked) and a ``checksum'' (count of the number of -backslashes in the code sections) could be checked. These features -are not really needed with modern distribution mechanisms and can be a -distraction when reading the source code and so have been removed. The -\package{doc} package has been updated so that if you use a -\verb|\CheckSum| command then, as before, the number is checked; -however, if you omit the command then no error or warning is given. - - -\section{Updates to \package{inputenc}} - -The UTF-8 support in \package{inputenc} has been further extended with -support for non-breaking hyphens and more dashes. - -\section{Updates in Tools} - -The \package{varioref} package has been updated with improved -documentation of multi\-lingual support, and avoiding unnecessary warnings in -some cases with \verb|\reftextfaraway|. - -The \package{tabularx} package's handling of \verb|\endtabularx| in -environment definitions has been fixed to again match its documentation. - -The \package{bm} package has been updated as required by the changes -to \verb|\mathchardef| in Lua\TeX. - - -\section{amsmath} - -Since the launch of \LaTeXe\ in 1993, the \textsf{amsmath} bundle has -been part of the \emph{required} packages in the core \LaTeX\ -distribution, with bug reports handled by the \LaTeX\ bug database at -\url{https://latex-project.org/bugs-upload.html}. - -The \textsf{amsmath} packages and the \textsf{amscls} classes have -been maintained by the American Mathematical Society. - -With this release a new arrangement has been agreed between the -American Mathematical Society and the \LaTeX3 project. The \LaTeX3 -project will take over maintenance of the \textsf{amsmath} bundle, -with the American Mathematical Society retaining maintenance of -\textsf{amscls}. - -The recommended installation of these files in the \TeX\ directory -structure remains unchanged as \path|tex/latex/amsmath| and -\path|tex/latex/amscls| respectively. - -This release of \package{amsmath} includes several updates so that -\package{amsmath} does not generate errors when math is used with -Lua\TeX\ v0.87+, which has changes to \verb|\mathchardef| that are -incompatible with the previous version of \package{amsmath}. It also -improves \verb|\dots| handling so that \verb|\long| macros are -correctly handled (for example, \verb|\dots \Rightarrow| now -uses centered dots), as well as commands expanding to character tokens -(for example, \verb|\times \dots \times| will use centered dots with -\verb|\times| defined as in the \package{unicode-math} package). - -\section{Related updates} -In addition to the updates in the core \LaTeX\ release, some files in -the CTAN ``contrib'' area have also been updated. Notably there have -been further updates to the \textsf{unicode-data} files; also, the -files required to build plain and \LaTeX\ formats have now been -submitted to CTAN as \textsf{tex-ini-files}. The -addition of a new \texttt{luatex} option for \textsf{graphics}-related -packages (\textsf{luatex-def} on CTAN) has required updates to the -configuration files to select a -default option and these have similarly been uploaded to CTAN as -\textsf{graphics-cfg}. (Previously these files were maintained -directly in the \TeX\ Live repository, and were not available on CTAN.) -\end{document}
