The second release candidate for v0.30.0 is out. This should be real close to the final release. You can get it from <
https://github.com/LeelaChessZero/lc0/releases/tag/v0.30.0-rc2>. In this release:
* WDL conversion for more realistic WDL score and contempt. Adds an Elo based
WDL transformation of the NN value head output. Helps with more accurate play
at high level (WDL sharpening), more aggressive play against weaker opponents
and draw avoiding openings (contempt), piece odds play. There will be a blog
post soon explaining in detail how it works.
* A new score type `WDL_mu` which follows the new eval convention, where +1.00
means 50% white win chance.
* Simplified to a single `--draw-score` parameter, adjusting the draw score from
white's perspective: 0 gives standard scoring, -1 gives Armageddon scoring.
* Updated describenet for new net architectures.
* Added a `first-move-bonus` option to the legacy time manager, to accompany
`book-ply-bonus` for shallow openings.
* Changed mlh threshold effect to create a smooth transition.
* Revised 'simple' time manager.
* A new spinlock implementation (selected with `--search-spin-backoff`) to help
with many cpu threads (e.g. 128 threads), obviously for cpu backends only.
* Some assorted fixes and code cleanups.
