TODO + - ensure shared memory variables are visible in weird build setups + * afl-cmin + - work with input files that have a space + * afl-showmap + - minor fix to collect coverage -C (thanks to @bet4it) + * enhanced the ASAN configuration + + +### Version ++4.20c (release) + ! A new forkserver communication model is now introduced. afl-fuzz is + backward compatible to old compiled targets if they are not built + for CMPLOG/Redqueen, but new compiled targets will not work with + old afl-fuzz versions! + ! Recompile all targets that are instrumented for CMPLOG/Redqueen! + - AFL++ now supports up to 4 billion coverage edges, up from 6 million. + - New compile option: `make PERFORMANCE=1` - this will enable special + CPU dependent optimizations that make everything more performant - but + the binaries will likely won't work on different platforms. Also + enables a faster hasher if the CPU requirements are met. + - The persistent record feature (see config.h) was expanded to also + support replay, thanks to @quarta-qti ! + - afl-fuzz: + - the new deterministic fuzzing feature is now activated by default, + deactivate with -z. Parameters -d and -D are ignored. + - small improvements to CMPLOG/redqueen + - workround for a bug with MOpt -L when used with -M - in the future + we will either remove or rewrite MOpt. + - fix for `-t xxx+` feature + - -e extension option now saves the queue items, crashes, etc. with the + extension too + - fixes for trimmming, correct -V time and reading stats on resume by eqv + thanks a lot! + - afl-cc: + - added collision free caller instrumentation to LTO mode. activate with + `AFL_LLVM_LTO_CALLER=1`. You can set a max depth to go through single + block functions with `AFL_LLVM_LTO_CALLER_DEPTH` (default 0) + - fixes for COMPCOV/LAF and most other modules + - fix for GCC_PLUGIN cmplog that broke on std::strings + - afl-whatsup: + - now also displays current average speed + - small bugfixes + - Fixes for aflpp custom mutator and standalone tool + - Minor edits to afl-persistent-config + - Prevent temporary files being left behind on aborted afl-whatsup + - More CPU benchmarks added to benchmark/ + + +### Version ++4.10c (release) + - afl-fuzz: + - default power schedule is now EXPLORE, due a fix in fast schedules + explore is slightly better now. + - fixed minor issues in the mutation engine, thanks to @futhewo for + reporting! + - better deterministic fuzzing is now available, benchmarks have shown + to improve fuzzing. Enable with -D.
