Here are release notes:
1. minor bug fixes: fixed a bug that occasionally crashed the engine, mostly running on multiple CPU cores. That is the bug that crashed Fizbo twice in TCEC10 .
2. minor changes to search and evaluation.
3. changes to parallel search, improving performance mostly on >4 CPU cores.
Expected playing strength is approximately 20-30 ELO higher than Fizbo 1.9
Many thanks for this version 2.0
My testing machine uses only 32 bit OS, would be nice if there's a 32bit version.

It seems item [2] was my mistake. Somehow the Threads setting in ArenaEng.cfg had been set back to 1 from 8. Not sure how, but never mind.

I am sure many people will appreciate this blitz game played by Fizbo 2 against Texel 1.07a35 in a true gambit style:

Thank you Youri! Always fun to see Fizbo go for positions other engines seem to avoid
. Here is some feedback based on reviewing many test games. First, the good news: it has been stable, with no crashes. Second, it does lose some games on time (based on 3+2 4CPU blitz games).
This includes games where F is clearly better but runs out of time despite the increment. Seems like a move overhead parameter could be helpful.
Thank you again,
Peter
