[XeTeX] XeTeX 0.993 for Mac OS X

[Jonathan Kew]

There is a new release of XeTeX available for Mac OS X. Version 0.993  
comes with both PowerPC and Intel binaries, and includes several new  
features including the much-requested "glyph metrics" mode (enabled  
by default in the standard xetex.fmt and xelatex.fmt formats).

A few notes of caution for the early adopters out there:

(a) This was built on Mac OS X 10.4 (Tiger), and has not been tested  
on earlier systems. I'm guessing it won't run on Jaguar; don't know  
about Panther. I have left version 0.99b available on the Download  
page as a fallback option for people with older systems.

(b) The Intel build, in particular, has had relatively little testing  
(well, to be honest, no XeTeX version gets much testing before you  
guys get hold of it), as my normal working machine is still an old  
Power Mac. As far as I know, it should work identically (except  
faster), but beware of lingering bugs!

(c) Because of the new glyph-metrics support, many existing documents  
will format differently with the new version (depending on how fonts  
and line spacing were used). You can revert to the old behavior with  
\XeTeXuseglyphmetrics=0 in your document, if required.

(d) I won't be around much over the weekend, to look into any  
problems that show up.

Having said that, as far as I'm aware it should work fine, and be an  
improvement on previous versions. YMMV! :)

As always, it's at <http://scripts.sil.org/xetex>, and also available  
through i-Installer.
