Hey, Lynx author here.
It's supposed to be slowly improving, but I understand the changes between 0.5.x and 0.6.0 are subtle enough not to have a visible impact in apparent strength, specially in fast control times

Thanks a lot for testing all the versions Alex, I'll keep working on it!

No problem, I continue to test the new versions, keep up the good work!

Velvet 3.0.0: https://github.com/mhonert/velvet-chess ... tag/v3.0.0

The major feature of this new release is the support for multi-threaded search using the Lazy SMP approach.

Interesting... another Rust engine. In some spots (such as the FEN reader and UCI handling, but not limited to those), Velvet uses a very similar architecture, structure, conventions, and sometimes even naming as Rustic. The engine was started a year later than Rustic, and seems to have progressed at rocket speed.

I don't mind if that's the case, but if so, some credits would have been nice. It _could_ of course be that the use of the Rust language makes people naturally use some architectures over others. Still, I get the feeling that Rustic may have been an inspiration to early versions of this engine, in the same way as VICE was an inspiration to the earliest versions of Rustic (but code all except the castling permission table has disappeared before Alpha 1).
