New is also that the source tree is now brought back in the original WinBoard 4.2.7 format, including

it to play Xiangqi. But no crazyhouse holdings yet.

After the given number of full moves without capture or Pawn move, the
game is adjudicated draw. Even without legality testing. The engines
retain the legal right to claim after 50 moves.
-/testClaims=FALSE
+/testClaims=FALSE
When enabled, this option verifies all result claims made by the
engines, and overrules the claim if it is false (forfeiting the game
for the claimer). An engine can still safely claim a win for its
as the GUI adjudicates checkmates (and stalemates) before any engine
can claim them.

-/boardWidth=8
+/boardWidth=8
Sets the number of files on the board. The additional files are named
i, j, k, l... in PGN, and should be indicated this way in
communicating moves to and from the engine. Currently works upto
12. No guarantees on how the rest of the display (clocks, etc.) looks
if you make this number < 8.
-/boardHeight=8
+/boardHeight=8
Sets the number of ranks. Extra ranks are numbered 9, 10, 11... in
PGN. This is so far largely untested, and unlikely to work for
double-digit ranks. Displaying boards with upto 12 ranks seems to
more than 9 ranks the counting of ranks will start at zero rather than
one!
-/fontPieceToCharTable="......."
+/fontPieceToCharTable="......."
This paramater, controlling the mapping of font symbols to piece
types, was already present in Winboard_x. The default is dependent on
the font selected with the /renderPiecesWithFont option. It can now
others are assigned in the order Pawn, Knight, ... Pieces that do not
get a symbol assigned will remain invisible.

The letters ACDEFGHMOW are accepted in FENs in addition to the regular
PNBRQK,(and of course the lower case versions for black), and are
passed to the engine in a setboard or edit menu. Double-digit skips
appear as choices in the promotion popup box.
-/variant="normal"
+/variant="normal"
Several new variants names are added (replacing "variant31" upto
"variant36"). They affect the initial position. (Board size has to be
set separately.) They are: courier (a Medieval predecessor of modern
