Update on updates

Since I'd previously described my planned timeline for 8.1, 8.2, etc, I wanted to add that that timeline's kind of out the window since the engine-shift turned out to have a more fundamental impact (performance, and in some cases simple stability) on more users than we'd realized.  I will get back to AIW refinement but for now there's a mess to be cleaned up

On the plus side, that means I have more time to finish up my UI improvement document .
