Some great stuff in this release. I contributed some rendering code, most notably reducing the renderer to O(number of changed entities) on the CPU, that went unmentioned in the release notes.

I do have to say, however, that BSN syntax isn't good and is getting worse. There are too many sigils, and -- to separate list elements (!) is an indication that it's been designed into a corner. The fact that it's not LR(1) should have been an indication that it was misdesigned. The scene format should be redesigned to be editor-first, with ease of VCS merging as a paramount consideration.
