-----------
Cloth: Old RC1 and RC2 files with cloth should open again and not crash (after the DNA rearrangement to fix a bug yesterday). But be carefull your settings get lost. Best thing to do: 1. write settings down, 2. open blend in new (>=17 subversion) blender and just save the file (and ignore warnings on the command line.) Take this as a good example why not to use svn blender versions for production purposes ;)
