cpuminer-opt v3.1.13 just released. Added support for a few dusty algos:
sha256d, scrypt, scryptjane and yescrypt.

This just about completes the conversion from cpuminer-multi. Some numbers:

37 algos
31 algos pool tested
14 algos optimized with AES_NI support
6 algos benchmark tested only, need pool testing

See all the details in the first post of this thread.

If anyone  knows of anywhere to pool test any of the remaining algos please let me know.
I'll even test you your address.

There's nothing pressing in the pipeline so this will probably be the last release for a while,
barring bug fixes. I hope you all enjoy it.

Edit: cpuminer-opt can now mine all algos at hashpower, zpool and yiimp, all but whirlpoolx at nicehash,
all but hashimoto (ethereum), spreadx11 and m7m at suprnova, and all but scryptn at miningpoolhub.
