+~~~~~~~
+* 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.
