new versioning system
code improvements & optimizations

Fire 8.3

This release provides greatly improved play at ultra-fast time controls, eliminating the timeouts experienced by previous versions.

1000ms + 100 ms (avg. game 14 secs):

engine	games	win	loss	draw	timeouts	win%	elo	los
Fire 8.3	1078	+352	-225	=501	0	55.9 %	+42 elo	100%
Fire 8.2	1078	+225	-352	=501	182	45.1%	-42 elo	0%

available Windows binaries

• x64 bmi2 = fast pgo binary (for modern 64-bit systems w/ BMI2 instruction set) if you own a Intel Haswell or newer cpu, this compile should be fastest.
• x64 avx2 = fast pgo binary (for modern 64-bit systems w/ AVX2 instruction set) if you own a modern AMD cpu, this compile should be the fastest.
• x64 sse41 = fast pgo binary (for modern 64-bit systems w/ popcnt instruction set)

The codebase should compile under Linux, but has not been tested

Fire 8.2

• code improvements
• optimizations
• speed improvement
• build timestamp
• compile info

Binaries (windows only) are available:
Fire_8.2_x64_avx2.exe
Fire_8.2_x64_bmi2.exe
Fire_8.2_x64_sse41.exe

The codebase should compile under Linux, but has not been tested
