Author(s): Mattia Giambirtone
Release Date: 2024-12-13
Language: Nim
Protocol: UCI
Repo Owner: nocturn9x
Repo URL: https://git.nocturn9x.space/nocturn9x/heimdall

This release addresses a bug that I had inadvertently introduced while refactoring Heimdall’s SMP functionality. For simplicity (and my own sanity), I have reverted the change and switched back to the old way of spawning threads, which means they are re-created at every go command (inefficient, but at least it works!)

Please refer to 1.2’s release notes for an accurate changelog and strength improvements

It now returns to the version 10.00 neural network architecture but with the incremental evaluation update, and other search improvements.

In this release you will find the network file “tucano_nn03.bin” that has to be saved to the same folder as the executable file, or can be indicated in the parameters. Please review the readme.md file for more information.

Also includes executables for windows and linux (centos).
This version is stronger than previous 11.00 version.
