v.0.90:
-- Fixed two bugs in SEE (stopped the calculation if the first capture was of equal value, and failed to include Kings in the calculation)
-- Fixed a bug that could cause a save to the hash table even if there was no best move
-- Tuned PST files for the first time, and re-tuned all other eval terms
-- Captures with negative SEE value can now be reduced
-- IID is now more aggressive in its depth reduction and can be applied in PV nodes
-- LMR reduction is now one depth less for PV nodes
-- No longer limiting the number of extensions for a single branch
-- Reduced the number of aspiration windows before performing a full-width search from six to two
-- Fixed a rare bug such that if a tt probe or IID returned an underpromotion it would not be moved to the front of the movelist
-- Fixed an issue when receiving the "force" command while pondering, which can happen with some GUIs
-- Modified the compiler options for magicmoves to improve perft results by 5%.
-- Various minor optimizations
-- Added "see" command to return the SEE value of a capture on the current position - example usage "see d4 e5"
-- Added "rpt" command to run a brief perft test (perft uses bulk counting)
-- Removed "-64" from version string as there is no longer a 32-bit version
