I updated to the svn trunk version this morning and I can verify that any file modified by the new version, indeed, cannot be reverted be read by v1.6 or earlier. When I was playing with the svn version back in August, this would have been an enormous problem since it seemed extremely unstable.
It appears that the developers have since fixed a number of those problems, though. I've been using it all morning to work on the text for my book without a single hiccup. (After I figured out that I needed to specify a different -sysdir and -userdir or it would completely crap over my previous installation). I also fumbled around looking for the xetex settings, but once I got it figured out (it's under Document->Settings->Output for anyone else who might find themselves confused), I've been a very happy camper. The one feature that I would like to try out and can't seem to enable is the new spell checker. Squiggly red underlines is something that I've wanted to see in LyX for a very long time.
