WinBoard 4.3.13 released

[H.G.Muller]

I just released WinBoard 4.3.13.

New features compared to 4.3.12 are:

- Engines can now claim a draw that occurs only after their move by sending "offer draw" before the move, as WinBoard will treat offers in a 3-rep or 50-move situation as claims.
- Draw offers are only passed to the opponent after the offerer also gives its move
- Time-odds games are supported
- Search time is now stored together with depth/score in the PGN
- WinBoard now can receive options from the engine command line, so that options that follow the engine are possible (with any WB tournament manager)
- FRC is now fully supported (local and ICS play)
- There are 5 more fairy pieces, (22 piece types per side) amongst which several wildcard pieces (that may do any move, even when legality testing is on)
- Most fairy pieces are now also available as bitmaps in board size 'petite'
- Archbishop and Chancellor are available in 9 formats

Various bugs that occurred in 4.2.12 are fixed:
- KQKR is no longer considered trivial draw )i.e. black Queens are now counted as Queens, not Rooks...)
- KBKB with like Bishops is recognized as insufficient mating material
- The problems with Shatranj in ICS mode are fixed
- Sideway Pawn moves in Xiangqi are no longer considered e.p. captures
- Sideway steps of the Unicorn in Knightmate are recognized as castlings

All features of 4.3.12 and its predecessor WinBoard_x of course remain resent as well, amongst which the draw adjudications, mate- and draw-claim verification, font-based piece rendering, user-defined board textures, variable board sizes, showing of the holdings in Crazyhouse and other games with piece drops, variants Shogi and Xiangqi.

Downloads, one for the executable, one for the complete source code, is already available from Fonzy's website ( http://www.geenvis.net ).
Beware, it is still a beta version! Let me know about any problems.

Baron's happiness makes the win claim false.
