CHANGE HISTORY
--------------
- v0.8i (2017/11/18)
* Many internal changes to support future work.
* Improved documentation describing the `\mathXX` and `\symXX` commands.
* Documentation is now split into `unicode-math.pdf` (for the user)
and `unicode-math-code.pdf` (for the typeset source code).
- 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
