24 IV. REMARKS ON THIS RELEASE
27 ========================================================================
30 The amsmath package is an extension package for LaTeX that provides
31 additional features to facilitate mathematical typesetting. It has been
32 developed by the American Mathematical Society and released for general
33 use as a service to the mathematical community. A number of smaller
34 auxiliary packages are also distributed with the amsmath package.
36 Effective in 2016, maintenance of amsmath was transferred from AMS to
37 the LaTeX3 Project; as amsmath is considered a "required" package, this
38 centralizes control over the core LaTeX components.
40 ========================================================================
41 II. INSTALLATION AND GETTING STARTED
43 In order to use amsmath you need to have TeX installed first.
44 For information on getting TeX see one of the following:
47 http://www.ams.org/tex/tex-resources
49 It is recommended to install a comprehensive distribution, such as
50 TeX Live, MiKTeX for Windows, or MacTeX for Macintosh.
51 As part of the "required" LaTeX package subset, amsmath
52 will already be available if one of these distributions is chosen,
54 If you are installing amsmath manually, the most recent version
55 will be available from the CTAN archives
56 https://www.ctan.org/pkg/amsmath
59 The primary documentation for amsmath is in
63 Additional documentation files include:
70 which are included in the collection. All of these can be accessed
71 easily with most distributions by entering "texdoc filename" at the
72 command line, or via "TeXdoc Online" at http://texdoc.net .
74 ========================================================================
75 III. SUBMITTING BUG REPORTS
77 Bug reports should be submitted using the standard LaTeX bug reporting
82 http://www.latex-project.org/bugs/
84 and follow the resulting instructions. Select "amslatex" when asked
87 Questions regarding usage can be posted at http://tex.stackexchange.com .
88 Check first to see whether your question has already been answered.

91 IV. REMARKS ON THIS RELEASE
93 Version 2.16 adds some control over spacing around aligned/gathered and
94 adjustments to the generalized fraction code so that it works in xetex.

97 V. CHANGE LOG (REVERSE CHRONOLOGICAL ORDER)
100 2016-11-05 amsmath.dtx 2.16a
101 alignedleftspace[yes|no|yesifneg] package options
102 New genfrac implementation for XeTeX and LuaTeX
103 Delete obsolete install.txt file.
106 2016-06-28 amsmath.dtx 2.15d
107 avoid error on \dots \left ....
109 2016-05-26 amsmath.dtx 2.15c
110 ignore spaces at start of \intertext
112 2016-03-10 amsmath.dtx 2.15b
113 Preserve box0 in \resetMathstrut@
114 In xetex, and luatex, add version of \newmcodes@
115 that works even if - has a \Umathcode definition.
117 2016-03-03 amsmath.dtx 2.15a
118 One missing % added to mathstrut handling.
121 2016-02-20 amsmath.dtx 2.15
122 Updates for new \mathchardef handling in luatex
123 Fix for \long macros after \dots
124 (such as \iff as redefined by this package)
126 2013-01-14 amsmath.dtx 2.14
129 -- Minimal changes to make amsmath compatible with stix.sty.
131 2000-07-18 amsmath.dtx 2.13
132 -- After the numbering patches in 2.11, \notag failed in certain
133 circumstances: introduce some more auxiliary functions to sort
134 things out, and redefine \nonumber.
136 2000-06-29 amstext.dtx 2.01
137 -- Use \f@size instead of \tf@size because they are not
138 necessarily the same and the former is better for putting a few
139 words into a display.
141 2000-06-06 amsmath.dtx 2.12
142 -- Fix transposed lines in 2.11 patch.
144 2000-06-02 amsmath.dtx 2.11
147 -- Prevent "Arithmetic overflow" error by guarding against
148 divide-by-zero in \x@calc@shift@lc (align environment).
151 -- Moved to the amscls distribution.
153 2000-05-25 amsmath.dtx 2.10
154 -- Clear up error message for \allowdisplaybreaks[0].
155 -- Make mathdisplay re-entrant by introducing mathdisplay@stack,
156 to clear up numbering problems in unusual circumstances such as
157 \[ \] nested inside minipage inside equation.
159 2000-04-21 amsmath.dtx 2.09
160 -- Ensure good catcodes for " etc.
162 2000-03-16 amsmath.dtx 2.08
163 -- Fixed erroneous tag placement on split with fleqn/tbtags options.
165 2000-03-15 amsmath.dtx 2.07
166 -- Add \reset@strutbox@ to deal with the following bug: After
167 $...\mbox{\Huge $...$}...$, line spacing is wrong in a
168 following "gather" or other environment that uses \strut@.
169 -- Patch to fix bug with intlimits option: too much space in the
171 -- Overhaul math accents again to fix a couple of bugs reported by
174 2000-03-10 amsmath.dtx 2.06
175 -- Change \MathAccent to \mathaccentV so \DeclareMathAccent won't
176 give an error when redefining an accent.
178 2000-01-06 amsmath.dtx 2.05
179 -- Fixed incorrect placement of fleqn/reqno equation numbers
180 inside indented lists (displaywidth < columnwidth). Changed the
181 multline/fleqn/leqno indent to match mathmargin when possible
182 instead of always just using multlinetaggap.
