+Added minotaur algo for Ringcoin.
+
+v3.13.0.1
+
+Issue #262: Fixed xevan AVX2 invalid shares.
+
+v3.13.0
+
+Updated Windows binaries compiled with GCC 9. Included DLLs also updated.
+Icelake build (cpuminer-avx512-sha-vaes.exe) now included in Windows
+binaries package.
+
+No source code changes.
+
+v3.12.8.2
+
+Fixed x12 AVX2 rejects.
+Fixed phi AVX2 crash.
+
+v3.12.8.1
+
+Issue #261: Fixed yescryptr8g invalid shares.
+
+v3.12.8
+
+Yespower sha256 prehash made thread safe.
+
+Rewrote diff conversion functions from scratch to be simpler and use 
+long double (float80) and int128 arithmetic for improved accuracy and
+precision.
+
+Some code cleanup and assorted small changes.
+
+v3.12.7
+
+Issue #257: fixed a file descriptor leak which caused the CPU temperature
+and frequency query to report zeros after mining for a couple of hours.
+
+Issue #253: stale share reduction for yescrypt, sonoa.
+
+v3.12.6.1
+
+Issue #252: Fixed SSL mining (stratum+tcps://)
+
+Issue #254 Fixed benchmark.
+
+Issue #253: Implemented stale share reduction for yespower, x25x, x22i, x21s,
+x16*, scryptn2, more to come.
+
+v3.12.6
+
+Issue #246: improved stale share detection for getwork.
+
+Improved precision of target_to_diff conversion from 4 digits to 20+.
+
+Display hash and target debug data for all rejected shares.
+
+A graphical representation of CPU affinity is displayed when using --threads.
+
+Added highest and lowest accepted share to summary log.
+
+Other small changes to logs to improve consistency and clarity.
+
 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.
+
+Issue #252: Fixed stratum+tcps not using curl ssl.
+
+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.

+ * This is a proof-of-work focused fork of yescrypt, including reference and
+ * cut-down implementation of the obsolete yescrypt 0.5 (based off its first
+ * submission to PHC back in 2014) and a new proof-of-work specific variation
+ * known as yespower 1.0.  The former is intended as an upgrade for
+ * cryptocurrencies that already use yescrypt 0.5 and the latter may be used
+ * as a further upgrade (hard fork) by those and other cryptocurrencies.  The
+ * version of algorithm to use is requested through parameters, allowing for
+ * both algorithms to co-exist in client and miner implementations (such as in
+ * preparation for a hard-fork).
+ *
+ * This is the reference implementation.  Its purpose is to provide a simple
+ * human- and machine-readable specification that implementations intended
+ * for actual use should be tested against.  It is deliberately mostly not
+ * optimized, and it is not meant to be used in production.  Instead, use
+ * yespower-opt.c.
