Summary description: Unicode mathematics support for XeLaTeX and LuaLaTeX
License type: lppl
Announcement text:

After an interminable wait, this release fixes a terribly embarrassing incompatibility with recent versions of expl3. I'm very sorry for any inconvenience. Other changes are listed below: * 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

This package is located at http://mirror.ctan.org/macros/latex/contrib/unicode-math . More information is at http://www.ctan.org/pkg/unicode-math (if the package is new it may take a day for that information to appear). We are supported by the TeX Users Group http://www.tug.org . Please join a users group; see http://www.tug.org/usergroups.html . Thanks for the upload. For the CTAN Team Rainer Schöpf

## unicode-math – Unicode mathematics support for XeTeX and LuaTeX

This package will provide a complete implementation of unicode maths for XeLaTeX and LuaLaTeX.

Unicode maths is currently supported by the following freely available fonts:

- Latin Modern Math (Bogusław Jackowski, Janusz M. Nowacki),
- TeX Gyre Bonum Math (Bogusław Jackowski, , P. Strzelczyk, Janusz M. Nowacki),
- TeX Gyre Pagella Math (Bogusław Jackowski, , P. Strzelczyk, Janusz M. Nowacki),
- TeX Gyre Schola Math (Bogusław Jackowski, P. Strzelczyk, Janusz M. Nowacki),
- TeX Gyre Termes Math (Bogusław Jackowski, P. Strzelczyk, Janusz M. Nowacki),
- DejaVu Math TeX Gyre (Bogusław Jackowski, P. Strzelczyk, Janusz M. Nowacki),
- Asana-Math fonts (Apostolos Syropolous),
- STIX (STI Pub),
- XITS Math (Khaled Hosny),
- Libertinus Math (Philipp H. Poll and Khaled Hosny), and
- Fira Math (Xiangdong Zeng).

The following fonts are proprietary with OpenType maths support:

- Lucida Bright Math (Charles Bigelow and Kris Holmes),
- Cambria Math (Microsoft),
- Minion Math (Johannes Küster, typoma GmbH).

As well as running XeTeX or LuaTeX, this package requires
recent versions of the
fontspec,
expl3,
`xpackages`,
ucharcat and
lualatex-math packages.
