It contains support for 6-piece SYZYGY tablebases and introduces extensive changes to evaluation function. In TCEC Season 9 Fizbo will participate with a version that will receive a few last minute improvements to gain more ELO points.

Latest development was been focused on searching for additional features of evaluation function using automated coefficient tuning methods.
