Update: For the OBJ Exporter fixes, all files from https://svn.blender.org/svnroot/bf-blender/trunk/blender/release/scripts/op/io_scene_obj should be copied.

Blender 2.54 Beta has been released! This is the second beta release for the Blender 2.5x series. Here a quick summary of the main work that's been done since Blender 2.53 beta:
- Almost 200 (!) bugfixes. During this period close to 700 issues were reported to our tracker, about 675 closed. For some graphs and stats visit Blender Foundation: Status Update Week 36
- RNA Renaming. A lot of names were changed in the RNA level. For those who have used drivers a lot in Blender 2.53, there is a helper script in the help menu to fix the paths.
- RNA Properties API changed, see [Bf-committers] PyRNA type definition changes (postpone beta until end of week) for proposal and implementation details
- Audaspace/Game Engine API GSoC merged (audio py api, game.logic and GE in general, port Yo Frankie! to work with)
As you can see, mostly the effort concentrated on bug fixing, and some major changes in API, but not much new things. After this beta we'll continue with squashing all those bugs (still over 380 open!).
A crucial bug with the OBJ exporter was identified just as the binaries were being built and uploaded. If you need this you can get the correct version of the OBJ exporter from:
In the tarballs and .zip releases, look for the directory 2.54/scripts/ops/io_scene_obj and copy the file from the link on top of the existing export_obj.py
In the app bundle, go into blender.app and also look for the directory 2.54/scripts/ops/io_scene_obj. Copy the export_obj.py from the repository over the existing one.
For windows installer, if you installed with datafiles into installation directory, find the installation directory, and from there 2.54/scripts/ops/io_scene_obj, if you used user settings directory (application settings), look for %APPDATA%\Blender Foundation\Blender\2.54\scripts\ops\io_scene_obj. Copy the export_obj.py file from repository over the existing one.
