In this version, there have been general bug fixes and enhancements. However, the most notable thing is that the program now runs 2-3x faster as we are using a different program to read the PGN files. We are now using the pgnparser program, and not python-chess.
Other than that, custom branching has been implemented in a way that now when you look at the custom branching depth, it is the same as the default depth.
