+Release 3.4.7 of cpuminer-opt is available for download with support for
+Windows.
+
+cpuminer-opt now supports 38 algorithms on CPUs with at least SSE2
+capabilities including Intel Core2, Nehalem and AMD equivalent. See the
+performance chart below for details.
+
+In addition 19 algorithms have optimizations to take advantage of
+CPUs with AES_NI for even greater performance, including the Intel
+Westbridge and newer and AMD equivalent. See the performance
+comparison below.
+
+New in 3.4.7
+
+- fixed benchmark, except for x11evo
+- added CPU temperature to share submission report
+
+Users with non-SSE2 CPUs or who want to mine algos not supported by
+cpuminer-opt may find cpuminer-multi by TPruvot useful.
+
+Chart out of date, will be removed.
+
+The performance chart below is for an Intel i7-6700K @ 4 GHz, 16 GB mem.
+
+Normalization rates have been added to the chart to help with profit
+switching pools. Reference algo x11 = 1.
+
+Due to the peculiarities of some algorithms their performance on other CPU
+architectures may not scale equally. Their normalizations rates will also
+differ from those listed below. YMMV.
+
+Normalized profitability = algo profitability * norm rate

+Footnotes:
+(1) SSE2 rates are simulated in software (-march=core2) on an i7.
+(2) Benchmark tested only
+(3) CPU architecture not supported for algo. It won't work.
+(4) AES_NI Optimization not available for CPU artchitecture. Uses SSE2, slower.
+(5) Normalised profitability = algo profitability * norm rate, x11 = 1
+(6) Not supported on Windows
