- CmpLog forkserver
- Redqueen input-2-state mutator (cmp instructions only ATM)
- all Python 2+3 versions supported now
- changed execs_per_sec in fuzzer_stats from "current" execs per second
(which is pointless) to total execs per second
- afl-clang-fast:
- show in the help output for which llvm version it was compiled for
- now does not need to be recompiled between trace-pc and pass
