Minor changes with a lot of bug fixes and no changes in search and evaluation, parameters mostly unchanged. Does that contribute to any changes in elo?

and oh I think we have seen similar updates to many engines. It does contribute to some changes in elo, perhaps its few.

I've had it chomping on a position for a few minutes under CB and it hasn't stalled yet. That's a promising first sign.

Does beta-testing always lead to a quick release ?

You stole my line.
