Output tags which are not in the Seven Tag Roster like [ECO "A10"] rather than [ECO"A10"] in export format PGN. The Seven Tag Roster tags were, and are, done correctly.

Fix the validation of moves where a pawn captures something so the move is spotted as illegal if the pawn's specified start file does not match the square the pawn moves from. For example the sequence '1. e4 d5 2. cxd5' is now illegal where before it was treated as '1. e4 d5 2. exd5'. Sequences such as '1. e4 c6 2. c4 d5 3. cxd5' and '1. e4 c6 2. c4 d5 3. fxd5' were, and are, treated correctly.

Change project name to pgn-read and top-level package directory to pgn_read prior to upload to PyPI, but continue the version number sequence.

PGN is the name of a specification but pgn-read hints at the ability to read games from PGN files.

Fit unit tests to constant definition changes made in pgn-0.10.1.


30 October 2017


Improve correction, by editing, of errors detected in PGN text. Errors are put in a '{Error: ...}' comment and it is assumed such comments do not appear naturally. Any '}' put in the error comment are replaced by '::{{::' which is assumed to not appear naturally. The first move in the error comment will be incorrect.
