This presentation will review the current state of the XeTeX engine and associated packages, with an emphasis on features that have been added or updated over the past year, and will be included in the TeX Live 2008 release. These include updated OpenType support, synthetic font styles, the polyglossia macro package, updated math font support, built–in source/PDF synchronization support, and more.
We will also look at how XeTeX fits in with other TeX engines and with the wider software world. XeTeX is not the only extension of TeX providing Unicode and modern font support, but it is based on a quite different approach from others, both old (Omega) and new (LuaTeX). Each has both strengths and weaknesses, which users should consider when choosing the appropriate tool for their particular needs.
