Thanks for the heads-up on this. Yes, the latest version does indeed break
some of my code...
Would the best strategy be to stick with an earlier rev (6365 seems to be ok
for most of my code) and wait for things to settle down?
It depends: Do you want to get your work done, or you want to
help me track down the problems? :-)
If you have a helpful test-case that would be helpful,
but otherwise, if 6365 works for you, waiting makes sense.
By the way, I already noticed some performance problems as a result of
recent changes (something between 6330 and 6365),
That's a lot of changes. It might be helpful if you can track it down
to a specific change. OTOH, I've got a big set of changes (mostly
division-related) almost ready that may help, though I suspect
these changes would be orthogonal to whatever slowdown you've seen.
