OVERVIEW The amsmath package is an extension package for LaTeX that provides additional features to facilitate mathematical typesetting. It has been developed by the American Mathematical Society and released for general use as a service to the mathematical community. A number of smaller auxiliary packages are also distributed with the amsmath package. Effective in 2016, maintenance of amsmath was transferred from AMS to the LaTeX3 Project; as amsmath is considered a "required" package, this centralizes control over the core LaTeX components. ======================================================================== II. INSTALLATION AND GETTING STARTED In order to use amsmath you need to have TeX installed first. For information on getting TeX see one of the following: http://www.tug.org/ http://www.ams.org/tex/tex-resources 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 Additional documentation files include: 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" at http://texdoc.net . ======================================================================== III. SUBMITTING BUG REPORTS Bug reports should be submitted using the standard LaTeX bug reporting system: See the form at http://www.latex-project.org/bugs/ and follow the resulting instructions. Select "amslatex" when asked for a category. Questions regarding usage can be posted at http://tex.stackexchange.com . Check first to see whether your question has already been answered. ======================================================================== IV. REMARKS ON THIS RELEASE Version 2.16 adds some control over spacing around aligned/gathered and adjustments to the generalized fraction code so that it works in xetex. ======================================================================== V. CHANGE LOG (REVERSE CHRONOLOGICAL ORDER) 2016-11-05 amsmath.dtx 2.16a alignedleftspace[yes|no|yesifneg] package options New genfrac implementation for XeTeX and LuaTeX Delete obsolete install.txt file. 2016-06-28 amsmath.dtx 2.15d avoid error on \dots \left .... 2016-05-26 amsmath.dtx 2.15c ignore spaces at start of \intertext 2016-03-10 amsmath.dtx 2.15b Preserve box0 in \resetMathstrut@ In xetex, and luatex, add version of \newmcodes@ that works even if - has a \Umathcode definition. 2016-03-03 amsmath.dtx 2.15a One missing % added to mathstrut handling. 2016-02-20 amsmath.dtx 2.15 Updates for new \mathchardef handling in luatex Fix for \long macros after \dots (such as \iff as redefined by this package) 2013-01-14 amsmath.dtx 2.14 * amsmath.sty 2.14 -- Minimal changes to make amsmath compatible with stix.sty. 2000-07-18 amsmath.dtx 2.13 -- After the numbering patches in 2.11, \notag failed in certain circumstances: introduce some more auxiliary functions to sort things out, and redefine \nonumber. 2000-06-29 amstext.dtx 2.01 -- Use \f@size instead of \tf@size because they are not necessarily the same and the former is better for putting a few words into a display. 2000-06-06 amsmath.dtx 2.12 -- Fix transposed lines in 2.11 patch. 2000-06-02 amsmath.dtx 2.11 * amsmath.sty 2.11 -- Prevent "Arithmetic overflow" error by guarding against divide-by-zero in \x@calc@shift@lc (align environment). * amsdtx.dtx -- Moved to the amscls distribution. 2000-05-25 amsmath.dtx 2.10 -- Clear up error message for \allowdisplaybreaks[0]. -- Make mathdisplay re-entrant by introducing mathdisplay@stack, to clear up numbering problems in unusual circumstances such as \[ \] nested inside minipage inside equation. 2000-04-21 amsmath.dtx 2.09 -- Ensure good catcodes for " etc. 2000-03-16 amsmath.dtx 2.08 -- Fixed erroneous tag placement on split with fleqn/tbtags options. 2000-03-15 amsmath.dtx 2.07 -- Add \reset@strutbox@ to deal with the following bug: After $...\mbox{\Huge $...$}...$, line spacing is wrong in a following "gather" or other environment that uses \strut@. -- Patch to fix bug with intlimits option: too much space in the middle of \iint. -- Overhaul math accents again to fix a couple of bugs reported by Thimm. 2000-03-10 amsmath.dtx 2.06 -- Change \MathAccent to \mathaccentV so \DeclareMathAccent won't give an error when redefining an accent. 2000-01-06 amsmath.dtx 2.05 -- Fixed incorrect placement of fleqn/reqno equation numbers inside indented lists (displaywidth < columnwidth). Changed the multline/fleqn/leqno indent to match mathmargin when possible instead of always just using multlinetaggap. The file diffs-m.txt contains information on development and changes prior to 2000. [end]
