Editing XeTeX (section)

==History==

XeTeX was initially released for [[Mac OS X]] only in April 2004{{citation needed|date=December 2021}} with built-in [[Apple Advanced Typography|AAT]] and [[Unicode]] support. In 2005 support for OpenType layout features was first introduced. During BachoTeX 2006 a version for [[Linux]] was announced, which was ported to [[Microsoft Windows]] by Akira Kakuto a few months later, and finally included into [[TeX Live]] 2007 for all major platforms. XeTeX is also supported by [[LyX]] since version 2.0<ref>{{Cite web|url=http://wiki.lyx.org/LyX/NewInLyX20#backends|title=LyX wiki {{!}} LyX / New in LyX 2.0|website=wiki.lyx.org|access-date=2017-08-25}}</ref> and shipped with [[MiKTeX]] since version 2.7.
As of the inclusion in [[TeX Live]], XeTeX supports most macro packages written for [[LaTeX]], [[OpenType]], [[TrueType]] and [[PostScript]] fonts without any specific setup procedure.
Version 0.998 announced at [[BachoTeX]] 2008 supports [[Unicode normalization]] via the <code>\XeTeXinputnormalization</code> command.
Version 0.9999, released in May 2013, switched from [[International Components for Unicode|ICU]] Layout&nbsp;Engine to [[HarfBuzz]] for [[OpenType]] layout, and Graphite2 engine for [[Graphite (SIL)|Graphite]] layout, as well [[Core Text]] framework instead of [[ATSUI]] on Mac OS X.
