I saw people talking about AvaStar 2RC8 (2.0-46) in group chat. I can’t find any announcement of it being released. There is update information in the release notes: Fixed in Avastar 2.0-46 (Avastar-2-RC8).
There are about a dozen and half fixes.
There is also information about: Limited Bind Pose Support for Blender 2.79.
For those that do not know, the AvaStar people do provide code to update Blender. The Bind Pose stuff has value for non-AvaStar users.
