# CTAN Update: unicode-math

Date: July 31, 2011 3:50:44 PM CEST
On Sun, 31 Jul 2011 Will Robertson submitted an update to the unicode-math package. 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
