Full Changelog: 3.22.0...3.22.1

3.22.0

What's Changed

• Prevented potential errors with the SF process, and misc. by @johndoknjas in #80

  • If the user calls the __del__ method themselves, this could potentially result in an error, since the OS may call __del__ later. So in each call to __del__, ensure that self._stockfish is still running (i.e., = None).
  • A check is also implemented in the _put function, such that if self._stockfish isn't running, or if the "quit" command has already been sent to Stockfish, then the stdin.write() and stdin.flush() lines won't be executed.
  • Renamed the self.stockfish instance variable to self._stockfish, in order to indicate that it should be treated as private.
  • Changed the default search depth from 2 to 15, in case the user doesn't set it themselves. 15 is a good depth value since it's nearly instantaneous while still being fairly strong.
  • Added to the example in the readme for creating a Stockfish instance, in order to show how to send all the optional arguments together.

• Fixed README.md by @zhelyabuzhsky in #82
