Announcement release 2024/10/07
For mathtools.dtx v1.31
* Fix bug in the mathic option, initially reported in private email by
Lorents Landgren (#62).
A scratch counter was not properly initialised causing penalties to
be inserted where they should not.
Note that this fix is likely to change line breaks in existing
documents that uses the mathic option.
For empheq.dtx v2.17
* Fixed typo in manual reported by campa
Announcement release 2024/03/11
For mathtools.dtx v1.30
* Added a caveat about \xmapsto when ever unicode-math is loaded. The
macro does not work as the symbol marking the bar at the start is
not available under unicode-math. (#45)
* Added a default \MT_active_colon_false: for when centercolon=true has
never been executed (#49)
* Gave \DeclarePairedDelimiter... support for the empty scaler (dot) (#41)
* Added \xLongrightarrow and \xLongleftarrow (requested in #51)
* Added a bracing group inside \newtagform such that the inner format only applies to the number (fixes #54)
Announcement release 2022/06/29
For mathtools.dtx v1.29
* In section `Special mathtools options` clearified when `gathered` of pure amsmath might give a warning. (#38)
* Added 3.6 note 3: about \section{foo $\norm[\big]{bar}$}.
* Renamed a few colon combo symbols and added a few extra for completeness. (#44)
A package option is available to revert the change.
* Added a warning if mathtools is loaded *after* `unicode-math` (#43)
For mathtools.dtx v1.28a:
* fixed year typo in \ProvidesPackage
Announcement release 2022/02/02
For mathtools.dtx v1.28:
* added note about \eqref and showonlyrefs (#33)
* fixed typo in note about strange 3-arg \bracket command (#34)
* fixed typo in section 3.4.4 (strange \hphantom{g}) (#32)
* removed robustifying \(\)\[\], it is now in the LaTeX kernel (#30)
* added \xlongrightarrow and \xlongleftarrow (#12)
* added \MakeAboxedCommand to generate \Aboxed like macros (#32)
Announcement release 2021/04/12
For mathtools.dtx v1.27:
* fixed issue #25: Two typos in \MultlinedHook.
Announcement release 2021/03/28
For mathtools.dtx v1.26:
* LuaLaTeX has cramped primitives build in. We ought to use those when LuaLaTeX is used.
LuaLaTeX brances added, fixing issue #24.
Special thanks to Marcel Krüger, Ulrike Fischer and Philipp Stephani.
Announcement release 2021/03/18
For mathtools.dtx v1.25:
* fixed issue #18, thanks to Ruixi Zhang
* fixed issue #20 (via https://tex.stackexchange.com/a/252412/3929)
* fixed issue #22
* fixed issue #21, suggestions for documentation by Rimole.
* fixed issue #19
* fixed issue #17, thanks to Ruixi Zhang and David Carlisle
For mhsetup.dtx v1.4:
* fixed issue #15 by adding \MH_group_align_safe_begin/end: to
\MH_nospace_ifnextchar:Nnn. That way it should also work in tested
alignments. Solution provided by Phelype Oleinik
Announcement release 2020/03/24
* mathtools and empheq is now hosted at https://github.com/latex3/mathtools
* Additional ideas for math will now be added to mathtools as amsmath might not
be the right home for them at the moment.
* cleared up some documentation (reported by Frank Mittelbach,, issue #1)
* Explained a bit about nested \splitfrac and their need to be added
\mathstrut (reported by Frank Mittelbach, issue #2)
* added spaces to the arguments of \xLeftarrow, \xRightarrow and
\xLeftrightarrow moving the arguments away from the large arrow
head(s) (suggested by Frank Mittelbach, issue #3)
* added \xmathstrut an adjustable extention to the normal \mathstrut (issue #4)
* empheq: fixed several issues related to amsart/-book plus a few others
(issues #5, #6 and #8)
Announcement release 2020/01/17
* a few typos in the manual (from Mike Dworski)
* added \kern1sp in a few places related to showonlyrefs preventing
equation to add extra blank lines. This fixes both
https://tex.stackexchange.com/q/524598/3929 and
https://tex.stackexchange.com/q/257928/3929
Announcement release 2019/07/31
* fixed typo in manual (\Prop vs \Prob, reported by Shapour Madadpour)
* added \crampedsubstack and cramedsubarray (suggested by Henri Menke).
* added multlined hook fixes for smallmatrix and the smallmatrix variants we provide.
Announcement release 2018/01/08
* Fixed typo in \intertext, the interface for specifying the space
above and below now works as advertised.
Announcement release 2017/10/30
* fixed \null\, bug in (l|r|)gathered versions, bringing it in line with amsmath
Reported in https://tex.stackexchange.com/a/397718/3929
Announcement release 2017
* changed amsmath requirelemnt to 2016/11/05 (in order to use the aligend fix)
* Applied the amsmath aligned fix to multlined, now the left part aligned correctly
Reported by campa in a note to <https://tex.stackexchange.com/a/369212/3929>
* Reimplemented `\DeclarePairedDelimiter` and friends to fix the following problem:
\mathclose{\rvert}^2 vs \mathclose\rvert^2
They might not give the same result (depending on the font
setup). Thus the internal wrappers need to be changed into three
branches: star, nostarnonscaled, nostarscaled, where the
difference between the last two is whether or not braces are
applied to the fences.
This problem was reported in <https://tex.stackexchange.com/q/364308/3929>
* Since we were cleaning up `\DeclarePairedDelimiter` and friends,
`\DeclarePairedDelimiterX` is now implemented as a call to `\DeclarePairedDelimiterXPP`
with empty pre- and postcode.
* The \DeclarePairedDelimiter(X,XPP) reimplementation removes a grouping issue reported in
<https://tex.stackexchange.com/q/366665/3929>
* since there is no longer any `nostar` wrapper branch, redeclaring the `nostar` wrapper
will now give an error.
* Removed `-\jot` from the multlined implementation (invisible line). Issue reported in at
least <http://tex.stackexchange.com/a/258162/3929> and
<https://tex.stackexchange.com/q/369156/3929>. It is not 100% correct, but better than
with `-\jot`.
* fixed bug in empheq in relation to AMS clases
* renamed macros in mhsetup, mathtools and empheq such that any xxx_yyy: macro should now
contain EQ, MH or HT as a prefix or infix. Thus making everyting truely separate from
expl3 defined syntax.
* changed \shortintertext such that as long as 'original-intertext=false' (the default),
\shortintertext now only work in the same context as \intertext
* \shortintertext is now also an error inside the empheq construction
* sporadic space fixed in \noeqref, reported by Christian Vetter (private email)
* Added \ignorespaces after \noindent, bug inherited from amsmath
