Announcement:

GemRB 0.9.1 released! (Life is strength edition)

The GemRB team is proud to announce a new release.

It features loads of improvements in core game systems, making Icewind Dale
II almost completable, but also in the rest of the engine. Among other things
this means further improved speed, better unicode support and deprecation of
Python 2 support. As usual the release also comes with many smaller features,
bug fixes, polishing and code cleanups.
