Having replaced afl - which google barely maintains these days - with afl++ in all of my fuzzing projects, I can heartily endorse it! Keep up the good work
It's a bit of a shame that AFL upstream is (somewhat) dead. I'm now mainly using honggfuzz, and maintaining both projects downstream in Fedora. It would be nice if we had only one instrumented local fuzzing framework we could all use.
Why not have multiple with different strengths for different users, though? Honggfuzz is also really good.
That being said, most distributions replace afl with afl++ these days.
