As promised, the OpenType MATH enriched version of STIX fonts, XITS, is now available. This early version provides: * OpenType math constants values, necessary for proper layout of various math elements. * proper math accent positioning. * proper sub/superscript positioning (not fine tuned yet). * extensible radicals, delimiters and math accents. * oldstyle figures. * some pre-composed fraction. Tarball can be downloaded from: http://github.com/khaledhosny/xits-math/downloads Feature requests, bug reports and fixes, should be directed to the issue tracker: http://github.com/khaledhosny/xits-math/issues Against the practice of STIX project, this version have not been extensively tested, only few basic tests through ConTeXt MkIV were done. Instead, in the spirit of open development model, I'm releasing early and often and trusting that thee are many people with more knowledge of math aesthetics and sharp eyes to spot error better than what I can ever do. Others are highly welcomed to test against other OpenType MATH implementations, namely unicode-math (with both XeTeX and LuaTeX) and MS Office 2007 and higher.
