Since the last release (2015) the following issues have been addressed: * Changed amsmath requirement to 2016/11/05 (in order to use the aligned 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 (intertexts), bug inherited from amsmath
