| + | -- 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\\ | ||
