Animation upload differences 1.18 -> 1.19

I've discovered that there's a difference in the quality of uploaded animations between client version 1.18 and 1.19 (the current official release). See my later posts in this thread:

I just confirmed that it's an upload problem, not a playback problem. That is, animations I uploaded with 1.19 are crap in 1.18 and 1.19, and animations I uploaded with 1.18 are okay (by SL standards) in both versions.

Has anyone else noticed a recent (as of 1.19) problem?

Crap. Sorry for the alarm, but this is yet another error on my part. I did not, in fact, un-do all the optimization changes I made to 1.18. When I did, it created crap anims, too.
