v2.0.0-alpha-1

v2.0.0 is a complete rewrite of Zagreus. Despite most features not being implemented yet and the evaluation being fairly basic, it already seems to be outperforming v1 based on these stats:
ELO | 71.63 +- 15.10 (95%)
CONF | 60.0+0.60s Threads=1 Hash=64MB
GAMES | N: 2056 W: 1192 L: 774 D: 90

What's Changed

• Complete rewrite (v2.0.0) by @Dannyj1 in #7

Full Changelog: v1.2.0...v2.0.0-alpha-1

v1.2.0

• Reworked the search algorithm. Null Move Pruning isn't working properly yet, so I removed it for now. A lot of bugs were fixed in this search rework, so I found this update worth releasing anyway.
• Fixed an issue with UCI options not properly reporting a max value
• Changed the way Zagreus evaluates material balance
• Fixed an issue where endgame mobility was calculated in the midgame and vice-versa
• Bonus for pushing pawns towards promotion in the endgame (#2)
• Slight tweaks to mobility evaluation values (#3)
• Remove development score (#4)

Full Changelog: v1.0.1...v1.1.0

v1.0.1

It appears that 1.0.0 wasn't as stable as I had thought.

• Fixed an issue with zobrist hashes being incorrect after losing castling rights
• Fixed an issue with zobrist hashes being incorrect after castling
• Fixed incorrect zobrist hashes being used while ordering move, thus causing more nodes to be searched than needed and potentially wrong nodes being pruned.

v1.0.0

I now deem Zagreus stable enough to be released as a stable release.

• Further implemented the UCI protocol: Move Overhead option, Hash option, PV move reporting
• Added Tapered Evaluation
• Zagreus now uses PeSTO PST tables
• Improved mobility evaluation
• Improved king safety evaluation
• Improved evaluation performance
• Fixed an issue where Zagreus would not see 3-fold repetition.
• Fixed an issue with the Zobrist hash being incorrect after white takes EP
