New engine releases & news H2 2022

[Modern Times]

Indeed, it does not work with Cutechess GUI here either. 3.4b can now be selected to enter a tournament, but doesn't play properly. Maybe the author can look at Karballo 1.8, which is a java engine that does work.

FoxSEE 7.36.0 (src only so far)
https://github.com/redsalmon91/FoxSEE

Velvet 4.0.1
https://github.com/mhonert/velvet-chess

I compiled 7.36.0 for myself and noticed it has since ever it seems a bug in displaying nps,
because it mixes a time management variable with total time for nps calculation display.
(will be reported)

Hi,

Even though it may appear so at times, Rustic isn't dead. I've released three new versions as a preliminary cleanup so I can pick up development of Rustic 4 again. I have a few free days coming up at the end of the week and I hope to find some time to (almost) finish XBoard support and start work on the tuner.

For now, I've updated the Alpha 1, Alpha 2 and Alpha 3 branches so they compile cleanly with Rust Edition 2021 compilers and the currently latest versions of the libraries it depends on. These are maintenance releases. There is no functional difference to the previous versions. For normal playing and testing, the existing binaries can be used.

- Upgrade to Rust Edition 2021
- Upgrade 'rand' to 0.8.5
- Upgrade 'rand_core' to 0.6.3 (security fix)
- Upgrade 'rand_chacha' to 0.3.1
- Upgrade 'if_chain' to 1.0.2
- Upgrade 'clap' to 3.2.8
- Upgrade 'crossbeam-channel' to 0.5.5
- Upgrade 'crossbeam-utils' to 0.8.10 (security fix)

Caissa 0.7
https://github.com/Witek902/Caissa/releases/tag/0.7

I've implemented and trained custom neural network and completely dropped the one I "borrowed" from SF. This means that Cassia is now a legit and independent engine that can compete in CCRL.

There were two threads with testing for 2.0.0.5 in the appropriate section.

If I really had to speculate (not much games done and my own test was more for stability and visible bugs),
I would say 1850-1950 @CCRL Blitz scale for 2.0.0.5 so you need to make your own guess for 3.0.0.0.
