Contribute to KataGo's distributed training run!
- A new option in the main menu will assist you in setting up contributing to distributed training
- Included binaries for Windows, Linux and MacOS should all support this mode.
  - Keep in mind that the newer M1 macs needs you to compile katago yourself for this, as the current brew version does not support distributed training.
- You can watch games being played, exploring policy, potential moves and variations.
- Hit [spacebar] to switch between automatically playing and manually browsing through the current game.
- Most other options are disabled in this mode.
- See here for more details.
Setup position in new game
- The new game now has tabs for new game/edit rules/setup position
- Setup position will generate a position where one player is ahead.
- The intended use for this is to play against KataGo from an advantage, and try to win the game.
  - For an extra challenge use KataHandicap, but remember to manually set the playout doubling advantage.

The 'show dots' toggle is back to having only two options, all off and 'some on'.
- This was mainly due to the 'next mistake' navigation making the view with all evaluations somewhat redundant, and not warranting the confusing 3-state checkbox.
- The option to determine how many moves to show then on is back in analysis options configuration.
The window size/position is now saved on exit and restored on startup.
The fast analysis and rewind to start options in 'load game' are now remembered.
A new analysis option 'Reset analysis' was added which resets analysis to a single engine query, removing alternate moves and child move derived info.
A new shortcut [escape] stops all analysis.
- This can break some features which expect analysis to be present, such as AI moves. Resetting with h or toggling continuous analysis will typically fix such edge cases.
Nodes with clear location commands in the sgf (AE) are now correctly shown.
- However, they are not analyzed.
- Nodes with only edit position commands (AB/AW/AE) are now indicated in grey with a + in the move tree
Scoring by ownership square counting in japanese rules no longer confuses the last dame with a point.

Windows users can simply download and run the KaTrain.exe file attached, or download the KaTrainWindows.zip file and run the .exe in that (which is slightly faster to start up)
macOS users can use the attached KaTrainOSX.zip (unzip, mount .dmg, drag .app to applications)
- Note that on the newer Macs with M1 architecture, you still need to brew install katago, or compile katago yourself.
Linux and macOS users can install using pip3 install -U katrain or follow instructions here.
