Version 0.6.1 - February 4, 2010

- Fully validate "hash < target", rather than simply stopping our scan
  if the high 32 bits are 00000000.
- Add --retry-pause, to set length of pause time between failure retries
- Display proof-of-work hash and target, if -D (debug mode) enabled
- Fix max-nonce auto-adjustment to actually work.  This means if your
  scan takes longer than 5 seconds (--scantime), the miner will slowly
  reduce the number of hashes you work on, before fetching a new work unit.

Version 0.6 - January 29, 2010

- Fetch new work unit, if scanhash takes longer than 5 seconds (--scantime)
- BeeCee1's sha256 4way optimizations
- lfm's byte swap optimization (improves via, cryptopp)
- Fix non-working short options -q, -r

Version 0.5 - December 28, 2010

- Exit program, when all threads have exited
- Improve JSON-RPC failure diagnostics and resilience
- Add --quiet option, to disable hashmeter output.

Version 0.3.3 - December 27, 2010

- Critical fix for sha256_cryptopp 'cryptopp_asm' algo

Version 0.3.2 - December 23, 2010

- Critical fix for sha256_via

Version 0.3.1 - December 19, 2010

- Critical fix for sha256_via
- Retry JSON-RPC failures (see --retry, under "minerd --help" output)

Version 0.3 - December 18, 2010

- Add crypto++ 32bit assembly implementation
- show version upon 'minerd --help'
- work around gcc 4.5.x bug that killed 4way performance

Version 0.2.2 - December 6, 2010

- VIA padlock implementation works now
- Minor build and runtime fixes

Version 0.2.1 - November 29, 2010

- avoid buffer overflow when submitting solutions

Version 0.1.2 - November 26, 2010

- many small cleanups and micro-optimizations
- build win32 exe using mingw
- RPC URL, username/password become command line arguments
- remove unused OpenSSL dependency

Version 0.1.1 - November 24, 2010

- Do not build sha256_generic module separately from cpuminer.

Version 0.1 - November 24, 2010

- Initial release.
