 Change Log
 ----------
 
+v3.12.5
+
+Issues #246 & #251: fixed incorrect share diff for stratum and getwork,
+fixed incorrect target diff for getwork. Stats should now be correct for
+getwork as well as stratum.
+
+Getwork: reduce stale blocks, faster response to new work.
+
+Added ntime to new job/work logs.
+
+README.md now lists the parameters for yespower variations that don't have
+a specific algo name.
+
+v3.12.4.6
+
+Issue #246: fixed getwork repeated new block logs with same height. New work
+for the same block is now reported as "New work" instead of New block".
+Also added a check that work is new before generating "New work" log.
+
+Added target diff to getwork new block log.
+
+Changed share ratio in share result log to simple fraction, no longer %.
+
+Added debug log to display mininginfo, use -D.
+
+v3.12.4.5
+
+Issue #246: better stale share detection for getwork, and enhanced logging
+of stale shares for stratum & getwork.
+
+Issue #251: fixed incorrect share difficulty and share ratio in share
+result log.
+
+Changed submit log to include share diff and block height.
+
+Small cosmetic changes to logs. 
+
+v3.12.4.4
+
+Issue #246: Fixed net hashrate in getwork block log,
+            removed duplicate getwork block log, 
+            other small tweaks to stats logs for getwork.
+
+Issue #248: Fixed chronic stale shares with scrypt:1048576 (scryptn2). 
+
+v3.12.4.3
+
+Fixed segfault in new block log for getwork.
+
+Disabled silent discarding of stale work after the submit is logged.
+
+v3.12.4.2
+
+Issue #245: fixed getwork stale shares, solo mining with getwork now works.
+
+Issue #246: implemented block and summary logs for getwork.
+
+v3.12.4.1
+
+Issue #245: fix scantime when mining solo with getwork.
+
+Added debug logs for creation of stratum and longpoll threads, use -D to
+enable.
+
+v3.12.4
+
+Issue #244: Change longpoll to ignore job id.
+
+Lyra2rev2 AVX2 +3%, AVX512 +6%.
+
+v3.12.3.1
+
+Issue #241: Fixed regression that broke coinbase address in v3.11.7.
+
 v3.12.3
 
 Issue #238: Fixed skunk AVX2.
