Based on the discussion here
Is it already possible to use the STIX fonts?
it appears that the STIX project (release 1.1) supports LaTeX; I'm eager to get started with them!
TL2013 does have a current stix
package, which is based on release 1.0 and does not provide LaTeX support.
Question. Is there a reason that TL hasn't upgraded to version 1.1, or is this just a matter of time (and patience)? If there is a significant obstacle, could someone explain?
(I am aware that one could–in principle–install STIX v1.1 (or, of course, 1.2) by hand, but I am not exactly sure how to do that.)
Best Answer
as of now (november 2013), testing of the beta of the latex support for the stix fonts is well along. some work is needed on the fonts themselves, and i'm not sure when it will be ready for final release. however, i'm optimistic that it can happen before tex live 2014 is frozen.
the fonts and supporting package will certainly be uploaded to ctan as soon as they are ready, and the tex live crew takes in updates as they appear on ctan.
