- Engines can now use custom data files. This is useful for using a custom neural network with engines such as Arasan, Stockfish or Lc0.
- A node limit can now be specified in the engine settings dialog. This uses the UCI "go nodes" command and is useful for making Maia deterministic.
- The Play dialog now features a recent games list. Moreover, the logic which determines and remembers default values has been improved.
- Arasan has been updated to 23.3.
- Miscellaneous fixes and improvements.
