- Duo now uses the colors purple/orange.
- Junior now uses the colors green/orange.
- File format: accept whitespaces before and after property identifiers.
- Fixed a potential race condition during move generation.
- Dot indicating color to play in orientation selector was not always updated correctly after loading a file of a different game variant.
