[unreleased]

Improvements

Update to Stockfish 16.1.
- ⚠️ Stockfish now requires EvalFile and EvalFileSmall options to be set after launch, with a path to the *.nnue files provided.
- Currently chesskit-engine assumes nn-baff1ede1f90.nnue, nn-b1a57edbea57.nnue are available in your app's Bundle.main.
- Click the file names in the previous line to access the download pages.
- Any other files can be added via .setoption(id:value:) engine commands.
Engine.start() now takes a completion handler.
- This is called once the engine has finished initializing.
- Engine commands (i.e. setting options or requesting evaluations) should not be sent until this completion handler is called.

ChessKitEngine 0.3.0

Released Wednesday, March 27, 2024.

Improvements

Add background engine processing for better performance.
Remove neural network resource files for greatly reduced package size.
- These can be added manually by bundling the desired files and setting the appropriate engine to use them (see Resources directory).
- For Stockfish 15.1 (nn-1337b1adec5b.nnue):
```
engine.send(command: .setoption(id: "EvalFile", value: evalFileURL))
engine.send(command: .setoption(id: "Use NNUE", value: "true"))
```
- For LeelaChessZero 0.29 (192x15_network):
```
engine.send(command: .setoption(id: "WeightsFile", value: weightsFileURL))
```
