+
+1/12/2010 Version 4.8Q, implementing a reverse setup command for sending
+ pieceToCharTable and initial position to the GUI, sub-specification
+ of variant fairy through an engine-defined option, allowing Seirawan-
+ type gating moves in search. Seirawan Chess is added as new variant,
+ plus several new combinations of Chess with different armies
+
+7/10/2011 Version 4.8R, keeping better track of which pieces are virgin in a
+ setup position, and have a better distinction between use of the '4'
+ move-rights code between an initial double-step jump without e.p.
+ rights (as could so far only be used for Pawns, as the Spartan
+ Hoplite), and castlings. As a result even royal pieces can now get
+ an initial double-step other than castling, which has been used to
+ implement Cambodian Chess as a sub-variant of Makruk (selected
+ through a new option). Falcon Chess was added as a new variant.
+
+12/2/2013 Version 4.8S. Fixes a lot of bugs:
+ * Setting up Seirawan positions with ungated pieces
+ * Making Seirawan gating with already gated pieces illegal
+ * Fix undo in Seirawan (by remembering gatings)
+ * Recognizing drop moves as illegal moves
+ * Hash-table was only half used
+ * Spurious result claims after under-promotion
+ * False mate claims in Spartan when promotion to K was possible
+ * Fix bug in Berolina e.p. capture that is actually non-capture
+ * Fix conditions for check extension on capture of checker
+ * Fix Clear Hash option, which did not work at all
+ * Fix addition of 6th & 7th-rank Pawn bonus when setting up position
+ * Adapt score by true piece value in case of (under-)promotion
+ In addition it prints msec-accurate timing info,
+ and can implement limited range sliders of range up to 5.
+ Some game definitions using the Remarkable Rookies army (which
+ uses a range-4 Rook) have been added as sub-variants of fairy.
