Hi all,<br>
<br>
I have just uploaded a beta release of 0.9999.x series.<br>
<br>
The archive can be downloaded from SourceForge page:<br>
<br>
<a href="https://sourceforge.net/projects/xetex/files/source/" target="_blank">https://sourceforge.net/projects/xetex/files/source/</a><br>
<br>
There have been quite some changes in this release, and testing is<br>
highly appreciated, the more testing the better, but please note that<br>
this is a beta release and should not be used in production<br>
environments. There are no pre-built binaries right now, but they should<br>
be available from TLContrib shortly.<br>
<br>
<br>
Main changes in this release:<br>
<br>
* Port OpenType layout from ICU LayoutEngine to HarfBuzz.<br>
HarfBuzz is actively maintained and generally have much wider support for<br>
OpenType spec, the switch fixes a number of OpenType bugs:<br>
- Support version 2 OpenType Indic specs.<br>
- Many other Indic OpenType bugs, and support for the latest additions to<br>
OpenType spec.<br>
- Incorrect application of contextual features.<br>
- Incorrect kerning in fonts that has both old “kern” table and new GPOS<br>
“kern” feature.<br>
- Allow suppressing Latin ligatures with ZWNJ.<br>
- Support for variation selectors.<br>
- Support for user-specified features with complex scripts.<br>
<br>
* Port Graphite layout to from SilGraphite to HarfBuzz and Graphite2. Which<br>
provides a more robust Graphite support and also fixes a number of Graphite<br>
bugs.<br>
<br>
* Port AAT font layout and font searching on Mac from the deprecated ATS/ATSUI<br>
to Core Text, and image support on Mac from QuickTime to ImageIO framework.<br>
XeTeX can be finally built on 64-bit Mac! Work contributed by Jiang Jiang.<br>
<br>
* Add “/OT” font variant, similar to “/ICU” which is now deprecated.<br>
<br>
* Add a “shaper” font option to specify HarfBuzz shapers (for testing).<br>
<br>
* Guessed script from input string if no one is given in the font definition,<br>
instead of defaulting to Latin.<br>
<br>
* Support 4-letter tags for Graphite features.<br>
<br>
* Use \U prefix for extended math primitives, allowing XeTeX and LuaTeX to use<br>
the same names for Unicode math primitives supported by both engines. The old<br>
\XeTeX* primitives have been deprecated and will be removed in the future.<br>
<br>
* Support OpenType math cut ins.<br>
<br>
* Fix “\show” and “\meaning” of “\Umathchar” to a print a form that is legal<br>
input.<br>
<br>
* Fix italic correction to not depend on space factor being zero for OpenType<br>
fonts.<br>
<br>
* Fix sporadic shifting of extensible accents.<br>
<br>
* Fix typesetting XeTeX’s WEB code, in addition to various slight improvements.<br>
<br>
* Prefer TrueType/OpenType over Type1 fonts with the same font name.<br>
<br>
* Support input pipes, in line with other engines.<br>
<br>
* Drop support for using “()” as font names quotes since it was causing file<br>
names with parenthesis not to be found.<br>
<br>
* Fix “\show” with characters outside BMP.<br>
<br>
* Print the actual character instead of hex code for characters outside BMP<br>
with “\show”, “\meaning”, “\showlists” and missing char log messages.<br>
<br>
* Fix letterspacing if zero width glyphs.<br>
<br>
* Try to get cap and x height from OS/2 table first.<br>
<br>
* Reject bitmap only fonts.<br>
<br>
* Include build date in “--version” output.<br>
<br>
