cpuminer-opt-23.6

ARM: Sha256dt, Sha256t, Sha256d 4-way now working and fully optimized for NEON, SHA also enabled but untested.
x86: Sha256dt, Sha256t, Sha256d faster SSE2 4-way.
ARM: Scrypt, Scryptn2 fully optimized for NEON, SHA also enabled but untested.
Linux: added a log when miner is started as root to discourage doing so.

cpuminer-opt-23.5

New version numbering drops the leading 3, the major version will now be the calendar year, the minor version identifies planned releases during the year.

BETA: 64 bit ARM support

• ARM 64 bit CPUs are now supported with source code for Linux. Windows is not supported.

• NEON, AES & SHA2 are supported.

• This the first public release and is early Beta quality.

• Some algorithms do not work on ARM or work at reduced performance.
  See wiki for details: https://github.com/JayDDee/cpuminer-opt/wiki/Support-for-AArch64.

• CPU archtecture and OS detection and logging now support ARM features.

• New 2way parallel hash for ARM also helps x86_64 CPUs without AVX2 on supported algorithms.

• Enhanced startup feature logs to support ARM.

• Removed startup logs for incompatible CPU/SW architectures.

• Added CPU architecture & OS type to RPC user agent string.

• Added share reject controls, a warning log is displayed at 10% reject rate, the miner exits with an error log at 50%.

• Removed argon2 algorithm.

• New CLI option "--bell" adds an ASCII bell code in the output string of error, warning, & rejected share logs. The option is disabled by default.
