Today, TeX Live 2012 has been released. TeX Live is a comprehensive TeX and LaTeX system for Windows, Mac OS X, Linux and other Unix systems. A special version called MacTeX 2012 is available for Mac OS X.
Changes to TeX Live 2011:
tlmgr supports updates from multiple network repositories.
The parameter \XeTeXdashbreakstate is set to 1 by default. This allows line breaks after em-dashes and en-dashes, which has always been the behavior of other engines and formats such as plain TeX, LaTeX, and LuaTeX. Explicitly set \XeTeXdashbreakstate to 0 for perfect line-break compatibility for existing XeTeX documents.
The output files generated by pdftex and dvips, among others, can now exceed 2gb.
The 35 standard PostScript fonts are included in the output of dvips by default.
In the restricted \write18 execution mode, set by default, mpost is now an allowed program.
A texmf.cnf file is also found in ../texmf-local, e.g., /usr/local/texlive/texmf-local/web2c/texmf.cnf, if it exists.
The updmap script reads a per-tree updmap.cfg instead of one global config.
Platforms: armel-linux and mipsel-linux added; sparc-linux and i386-netbsd are no longer in the main distribution, but are available for installation as custom binaries, along with a variety of other platforms.
