- the installer now re-synchronize MiKTeX's package database before installing or updating LaTeX-packages. This assures that new packages and renamed packages can automatically be installed when they are missing (fixes bug #9370)
- update the list of LaTeX packages that have to be installed when LyX is installed via the bundle installer for the first time on a PC
- add support for Turkish spell-checking
- the installer does nw the job of replacing the magyar.ldf with the fixed version [http://wiki.lyx.org/Windows/Hungarian]
- install the Mongolian hyphenation pattern to MiKTeX
- update eLyXer
- update to new MiKTeX installer that fixes a bug with updating Packages
- don't ship cbgreek because it is so huge that its download would last 10 minutes or more
LyX 2.0.x supports currently 147 LaTeX-packages. When LyX is first installed on a PC it took therefore about 10 minutes to install all supported and required packages. With the new installation method the installation speed only depends on the Internet speed and lasts with an average bandwidth now only 3.5 minutes.
(chkconfig.ltx asks LaTeX for each package separately and after each package installation the file name database of LaTeX was rebuild. And that cost a lot of time/CPU power)
