CHANGE HISTORY

  • v0.8h (2017/10/09)

    • Some bugs crept in in the last update due to some code rearrangement:
      • package version wasn't set;
      • some code was being executed at the wrong time;
      • \sqrt[]{} in LuaLaTeX gave incorrect output.
    • The layout of the code is now structured far more sensibly.
    • Remove (long deprecated) \resetmathfont; for years it has been a synonym for \setmathfont.

  • v0.8g (2017/10/02)

    • Better use of scriptstyle sizes in LuaTeX (I think a regression).
    • Fix regression (\mathbf etc. not being set automatically) caused by the renaming of a fontspec internal command.
    • Minor documentation improvements.
    • (Only relevant for me: I've also disabled the test suite almost entirely to begin a re-write for ‘continuous integration’.)

  • v0.8f (2017/08/02)

    • Emergency fix (thanks Bruno) for another bug revealed by expl3 update.

  • v0.8e (2017/07/30)

    • Add \surd to access the sqrt symbol.
    • Fix bug exposed by expl3 update to booleans.
    • Add Deja Vu Math TeX Gyre in list of symbols.
    • Add \sime alias for \simeq and \nsimeq for \nsime. (For negations it's helpful when they have consistent naming.)

  • v0.8d (2017/01/25)

    • vargreek-shape=TeX and vargreek-shape=unicode package options dropped; for consistency and compatibility, \phi and \epsilon should and will now behave the same as in TeX.
    • On that note, when using control sequences such as \mbfitsansvarphi (and so on), there were a few faulty definitions. The new behaviour is to consistenyl define the varphi and varepsilon ones as those with the "curly" designs.
    • Add \wideoverbar, \widebreve, \widecheck.
    • Add \mathsection, \mathparagraph.
    • Remove \mupvarbeta, upold(Kk)oppa, \up(Ss)tigma, \up(Kk)oppa, \up(Ss)ampi — none of these are maths symbols.
    • ! (\mathexclam) changed from \mathpunct to \mathclose for backwards compatibility with TeX.

  • v0.8c (2015/09/24)

    • Add \over(left/right)harpoon as "wide" accents.
    • Add RTL mathematics operators \arabicmaj and \arabichad, which correspond to U+1EEF0 and U+1EEF1, resp.
    • Remove catchfile package dependency.
    • Update some internal names to match expl3 standards.

  • v0.8b (2015/09/09)

    • Bug fix: Use the "ucharcat" package to simplify some code that caused some headaches with \tl_rescan:nn.

  • v0.8a (2015/08/06)

    • Fix bug with \vert, |, (l/r)vert, etc., displaying with the wrong characters.

    • Improve documentation to properly reflect changes in v0.8 and fix some broken examples.

    • No longer reset catcodes of : and @ during \setmathfont .

    • Fix remapping of alphabets (needed for Minion Math) in cases such as:

      \setmathfont[range=bfit->it]{MinionMath-Bold.otf}

  • v0.8 (2015/07/29) Breaking changes in this update!

    • \mathrm (\mathup), \mathit, \mathbf, \mathsf, and \mathtt revert to their traditional LaTeX meanings; they are set up to match their equivalent text fonts unless specifically set using \setmathrm and friends from fontspec or the new \setmathfontface in unicode-math. These commands should be used for multi-letter identifiers.

    • New "symbol" commands have been added, \symrm (\symup), symit, ..., to replace the behaviour of the old commands. These should be used for single-letter identifiers. See the package documentation for more detail on these and related commands.

    • Package options mathit=sym, mathbf=sym, etc., reverse the changes above to revert to pre-v0.8 behaviour for \mathXYZ. Regardless of package option, \symXYZ always maps to symbols and \mathtextXYZ is provided for the traditional \mathXYZ font switch.

    • New command \setoperatorfont to set the font used for commands such as \sin and \cos. Usage: \setoperatorfont\mathbf or any command defined with \setmathfontface.

    • Traditional LaTeX \DeclareMathAlphabet now works again for legacy font-loading packages.

    • Commands defined to "force" Greek letters with \upbeta and \itbeta, etc.

    • Assorted bug fixes and minor changes.

  • v0.7e (2014/06/30)

    • No longer assume fixltx2e has been loaded.
    • Some ascii math symbols have been renamed with a \math... prefix, such as \mathquestion.
    • Assume latest luaotfload is being used; no need for a separate unicode-math.lua script.
    • Assorted typos and minor bugs.

  • v0.7e (2013/05/04)

    • Track luaotfload updates.

  • v0.7d (2013/03/16)

    • More expl3 changes missed first time around. (Sorry again.)

  • v0.7c (2013/02/25)

    • The Latin Modern math font name changed TWICE. Only caught the first one. Sorry for any inconvenience caused.

  • v0.7b (2013/02/22)

    • Keep in sync with Latin Modern Math font name change.
    • Keep in sync with expl3 changes.

  • v0.7a (2012/07/28)

    • Keep in sync with expl3 changes.

  • v0.7 (2012/05/30): The TeX Live 2012 release.

    • Most changes (and all significant ones) in this release thanks to Khaled Hosny, who is now credited as an author of the package.
    • Many improvements for XeTeX support to take advantage of the new engine (v0.9998) in TL2012.
      • As a result, \resetmathfont is no longer required.
    • Improve \not to use pre-combined glyphs where possible.
    • LM Math is loaded by default.
    • Support bottom accents.
      • And add \wideutilde.
    • The ‘symbols’ document is somewhat better organised and contains information on whether a symbol is defined in plain TeX or amssymb.
    • Various other minor fixes and additions:
      • \underleftrightarrow added for fonts that support it.
      • Don’t overwrite mathtool’s \overbracket and \underbracket.
      • Bug in [range=...] parsing fixed.
      • Add \longdivision.
      • Add \lgroup and \rgroup.
      • Fix ‘moustache’ delimiters.
      • \openbox renamed to \mathvisiblespace, since it is already defined in amsthm as an empty box.

  • v0.6a (2011/09/19)

    • Always a bug that slips through the cracks! Fixes \left. and \right.
    • Add experimental package option warnings-off=... which allows warnings to be suppressed on an individual basis.

  • v0.6 (2011/09/18)

    • Keep in sync with fontspec internals (sorry for the small delay where things were broken)
    • Keep in sync with expl3 deprecated functions
    • Math versions (finally) implemented; can now change maths fonts mid-document without reinitialising everything (thanks to Ulrike Fischer and Ulrik Vieth)
    • Symbols file unimath-symbols.pdf now uses maths versions to compare all of the OpenType maths fonts I currently have access to
    • Over- and under- braces, brackets, and parentheses now work in XeTeX (thanks to Claudio Beccari)
    • Many internal changes, including a re-write of the range feature; it should now be faster and more robust
    • Tentative programmer's interface for querying the current math style: \l_um_mathstyle_tl.
    • Remove (outdated) interaction with beamer; you must specify professionalfonts manually for now
    • Quieten the console output when loading maths fonts with incomplete maths style coverage
    • Synonym added: \lnot -> \neg
    • Two added Unicode symbols (names tentative): \blanksymbol and \openbox (thanks to Apostolos Syropoulos)
    • Fixed literal sub-/super-script input.

  • v0.5e (2011/07/31)

    • Fix forward compatibility clash with deprecated expl3 functions (sorry)
    • Command names are now \protected; this makes them safe to use in moving arguments and so on
    • Similarly to the change in v0.5c, the main math font is now loaded in math family zero (equiv. to LaTeX's operators math font)
    • \mathring added
    • Ensure that a math font has been selected in order to prevent problems in minimal documents (this will be unnecessary when the OpenType LM math font is released)
    • Documentation for which was which of epsilon/varepsilon was backwards! (thank to Rasmus Villemoes for pointing this out)
    • Spurious \upUpsilon removed (the one at U+03A5 is now the correct one)
    • Typo when defining \dprime fixed (thanks to Ulrik Vieth for these last two)
    • Fix the math class of \modtwosum; it is now a large operator (thanks to Michael Ummels)
    • Move several LuaTeX-related patches to the lualatex-math package
    • Fixed mathtool's \cramped in XeLaTeX usage

  • v0.5d (2011/01/30)

    • Assorted improvements to LuaLaTeX support, including non-growing accents available in LuaTeX v0.65 and later
    • Improved behaviour with reading and using maths font dimensions
    • Better compatibility with legacy maths packages and environments (always more worked needed, though)
    • Fix the default setting for "vargreek-shape"

  • v0.5c (2010/09/27)

    • Fix a long-standing bug in XeLaTeX in which the "master" math families 2 and 3 weren't being set; hence fraction rules and many other parameters were not being set correctly
    • Stay in sync with internal fontspec changes

  • v0.5b (2010/09/19): Tune-up

    • Added missing symbols/synonyms: \diamond \smallint \emptyset \hbar \backepsilon \eth
    • \overline works for LuaLaTeX
    • Fix \slash; previously, it overwrote the text definition
    • \vartriangle now has the correct math class

  • v0.5a (2010/07/14): TeX Live 2010 release

    • Numerous documentation improvements
    • Bug fix against stray catcode changes
    • Add \mathcal and \mathbfcal as distinct from the Script style; these are only supported by the XITS fonts at present
    • Small changes to the range of symbols offered (especially note that \ac is now \invlazys to avoid acronym package clash)
    • Superscripts are allowed after primes (as they should be)
    • Numerous LuaLaTeX improvements, including roots and over/under braces.

  • v0.5 (2010/06/03): Initial CTAN release
