Gyatso v1.6.0 Released

Post by GyatsoYT »

I’ve just released **Gyatso v1.6.0**, the latest version of my open-source chess engine written in Nim.

The current estimated ratings are:

* **~3553 CCRL 40/15**
* **~3623 CCRL Blitz (2'+1")**
* **~3725 CCRL FRC**
* **~3585 COPE Bullet**
* **~3659 COPE Rapid**
* **~3680 COPE DFRC**

This release also introduces native Chess960 and Double Fischer Random support.

The project is still actively developed, and independent testing, feedback, and bug reports are always appreciated.

Hello,
thanks; v1.6.0 for Windows appears to fail hash memory allocation, if I don't mess up.
All the best,
Tibono

⚠️ Anyone who Downloaded or compiled the Binary before this message
its a humble request to Re-download or re-compile it as there was a bug in Uci Parsing which means The engine always played with the default 16mb hash and 1 thread regardless of whatever you set
this makes any tournament played by Gyatso Invalid and unfair
i would Suggest everyone to download the updated Binary or recompile from scratch Again.
