Changelog for python-chess

This project is pretty young and maturing only slowly. At the current stage it is more important to get things right, than to be consistent with previous versions. Use this changelog to see what changed in a new release, because this might include API breaking changes.

New in v0.3.0

  • Rename property half_moves of Bitboard to halfmove_clock.

  • Rename property ply of Bitboard to fullmove_number.

  • Let PGN parser handle symbols like !, ?, !? and so on by converting them to NAGs.

  • Add a human readable string representation for Bitboards.

    >>> print(chess.Bitboard())
    r n b q k b n r
    p p p p p p p p

New in v0.2.0

  • Implement PGN parsing and writing.
  • Hugely improve test coverage and use Travis CI for continuous integration and testing.
  • Create an API documentation.
  • Improve Polyglot opening-book handling.

New in v0.1.0

Apply the lessons learned from the previous releases, redesign the API and implement it in pure Python.

New in v0.0.4

Implement the basics in C++ and provide bindings for Python. Obviously performance was a lot better - but at the expense of having to compile code for the target platform.

Pre v0.0.4

First experiments with a way too slow pure Python API, creating way too many objects for basic operations.
