cpuminer-opt-3.4.3 is available for download. It includes faster m7m on most CPUs and Windows binaries.

Compiling was done on a i7-4790K (Haswell). AMD amdfam10 failed to compile due to AVX inconsistencies.
AMD btver1 appears to have been compiled without AES and AVX.
As this is the first release with pre-built portable Windows binaries there may be some problems. There are also
some specific questions I have that users may be able to answer. When reporting problems please provide all relevant
information such as CPU architecture, commands used, compile environment, error messages and any other information
that may be useful.
Specific questions:
I was not able to compile for Broadwell/Skylake on my Haswell. Does a native compile on these CPUs perform better than a
core-avx2 compile?
AMD performance is expected to be poor with the pre-built binaries. I suspect compiling for AMD on an Intel CPU may not
produce the optimum code. AMD users that can compile their own can confirm whether this is the case.
The major code optimisations involve AES, AVX and AVX2. The architecture that introduced these individual features should see
the biggest incremental improvement. I would like to know how much of a performance penalty exists if users were forced to
use a lesser compile. For example how much slower is Ivybridge using the corei7-avx vs a native compile or the core-avx-i build.
Thank you very very much
