• Implemented batching for GPUs, increasing speed.
• Added support for Tensor Cores on NVIDIA cards.
• Optimized Winograd code for CPU and GPU.
• Improved UCT formula.
• Improved root move selection by using Lower Confidence Bounds.
• Improved passing heuristics (disabled in self-play).
• Improved autotuner behavior in edge cases.
• The training code now supports mixed precision fp32/fp16 t...

• Added support for lz-analyze and lz-genmove_analyze GTP extensions. They provide real time information about the search and can be used by GUIs.
• Added support for lz-setoption to change options without restarting. Support setting max memory usage, visits, etc.
• Implemented Winograd F(4x4, 3x3) for CPU and GPU, speeding up large networks.
• Symmetrical positions in the opening are no...

This is a bugfix release for training game generation.

• Bugfix to Dirichlet noise being more uniform than intended (bug was introduced in v0.13).
• Tweaks to randomized move selection in training games to reduce needless blunders. Added extra options.

• Support for converted ELF Open Go networks.
• Network files no longer need to be ungzipped.
• Improved time usage.
  • Slowed down play, more consistent time usage from opening to middle game.
  • By default no longer exits early in fixed playouts or in Japanese byo yomi.
  • The engine will respond faster on large searches, tree cleanup happens in the background.
• Memory usage for...

• Added --benchmark option.
• Improved strength on long/deep searches, reduced memory usage.
• Improved time management logic.
• AutoGTP now cleans up old networks.
• Optimizations for CPU-only version, about 10% speedup.
• Bugfix: self-play games are now more diverse because "noise" moves are no longer pruned.
• Bugfix: pondering now respects playout/visit limits.
