cpuminer-opt-3.21.0

Added minotaurx algo for stratum only.
Blake256 & sha256 prehash optimised to ignore zero-padded data for AVX2 & AVX512.
Other small improvements.

cpuminer-opt-3.20.3

Faster c11 algo: AVX512 6%, AVX2 4%, AVX2+VAES 15%.
Faster AVX2+VAES for anime 14%, hmq1725 6%.
Small optimizations to Luffa AVX2 & AVX512.

cpuminer-opt-3.20.2

Bit rotation optimizations to Blake256, Blake512, Blake2b, Blake2s & Lyra2-blake2b for SSE2 & AVX2.
Removed old unused yescrypt library and other unused code.

cpuminer-opt-3.20.1

sph_blake2b optimized 1-way SSSE3 & AVX2.
Removed duplicate Blake2b used by Power2b algo, will now use optimized sph_blake2b.
Removed imprecise hash & target display from rejected share log.
Share and target difficulty is now displayed only for low diificulty shares.
Updated configure.ac to check for AVX512 asm support.
Small optimization to Lyra2 SSE2.

cpuminer-opt-3.20.0

#375 Fixed segfault in algos using Groestl VAES due to use of uninitialized data.

cpuminer-opt-3.19.9

More Blake256, Blake512, Luffa & Cubehash prehash optimizations.
Relaxed some excessively strict data alignment that was negatively affecting performance.

cpuminer-opt-3.19.8

#370 "stratum+ssl", in addition to "stratum+tcps", is now recognized as a valid url protocol specifier for requesting a secure stratum connection.
The full url, including the protocol, is now displayed in the stratum connect log and the periodic summary log.
Small optimizations to Cubehash, AVX2 & AVX512.
Byte order and prehash optimizations for blake256 & blake512, AVX2 & AVX512.

cpuminer-opt-3.19.7

#369 Fixed time limited mining, --time-limit.
Fixed a potential compile error when using optimization below -O3.

cpuminer-opt-3.19.6

#363 Fixed a stratum bug where the first job may be ignored delaying start of hashing.

Fixed handling of nonce exhaust when hashing a fast algo with extranonce disabled.

Small optimization to Shavite.

cpuminer-opt-3.19.5

Enhanced stratum-keepalive preemptively resets the stratum connection
before the server to avoid lost shares.

Added build-msys2.sh scrypt for easier compiling on Windows, see Wiki for details.

X16RT: eliminate unnecessary recalculations of the hash order.

Fix a few compiler warnings.

Fixed log colour error when a block is solved.
