Released on September 14, 2016.
This is the first RC build for the Bento project, containing the extended avatar skeleton and corresponding slider support. Related models for testing can be found at http://wiki.secondlife.com/wiki/Project_Bento_Testing.
The build contains minimal changes since the last Project Viewer build, chiefly a few small slider fixes to enforce right-left symmetry.
