Princhess 0.5.1
https://github.com/princesslana/prinche ... /tag/0.5.1

No ELO gains, just a bug fix.

I had a typo in a uci option. Hash listed a default of 1 when it's really 16. If anything using Princhess actually sent that default, then she would just crash (so also updated the minimum to 8)

Arasan 23.0 100 Elo worse than 22.3? On our list it is almost 200 better. Are you sure you are using the nets?

Did the tests of 23.0 use the AVX2 executable? 23.0 had only AVX2 SIMD support. Any of the other executables (arasanx-64-popcnt for example) would not use SIMD instructions and would be significantly slower. 23.1 does not have this issue anymore.

This solves the issue, I haven't AVX2.

Belofte 2.1.4 has been released. It is more a replacement of 2.1.3 with a lot of enhancements towards GUI programs and addition of a lot of UI features while no real difference on playing strength. Addition of more EPD support. A number of bug-fixes is included.

What is changed: Not a big change in strength, but increase of speed in BruteForce search (300%), QS NPS (20%), windows builds by 40%.
Self play indicates an increase if 50 elo in strength.
