- updated to 2.66c
  - renamed blacklist/whitelist to ignorelist/instrumentlist ->
    AFL_LLVM_INSTRUMENT_FILE and AFL_GCC_INSTRUMENT_FILE
  - warn on deprecated environment variables
  - afl-fuzz:
     - -S secondary nodes now only sync from the main node to increase
       performance, the -M main node still syncs from everyone. Added checks
       that ensure exactly one main node is present and warn otherwise
     - Add -D after -S to force a secondary to perform deterministic fuzzing
     - If no main node is present at a sync one secondary node automatically
       becomes a temporary main node until a real main nodes shows up
     - Fixed a mayor performance issue we inherited from AFLfast
     - switched murmur2 hashing and random() for xxh3 and xoshiro256**,
       resulting in an up to 5.5% speed increase
     - Resizing the window does not crash afl-fuzz anymore
     - Ensure that the targets are killed on exit
     - fix/update to MOpt (thanks to arnow117)
     - added MOpt dictionary support from repo
     - added experimental SEEK power schedule. It is EXPLORE with ignoring
       the runtime and less focus on the length of the test case
  - llvm_mode:
    - the default instrumentation is now PCGUARD if the llvm version is >= 7,
      as it is faster and provides better coverage. The original afl
      instrumentation can be set via AFL_LLVM_INSTRUMENT=AFL. This is
      automatically done when the instrument_file list feature is used. 
    - PCGUARD mode is now even better because we made it collision free - plus
      it has a fixed map size, so it is also faster! :)
    - some targets want a ld variant for LD that is not gcc/clang but ld,
      added afl-ld-lto to solve this
    - lowered minimum required llvm version to 3.4 (except LLVMInsTrim, which

- some targets want a ld variant for LD that is not gcc/clang but ld,
added afl-ld-lto to solve this
- lowered minimum required llvm version to 3.4 (except LLVMInsTrim, which
needs 3.8.0)
- instrument_file list feature now supports wildcards (thanks to sirmc)
- small change to cmplog to make it work with current llvm 11-dev
- added AFL_LLVM_LAF_ALL, sets all laf-intel settings
- LTO instrument_files functionality rewritten, now main, _init etc functions
need not to be listed anymore
- fixed crash in compare-transform-pass when strcasecmp/strncasecmp was
tried to be instrumented with LTO
- fixed crash in cmplog with LTO
- enable snapshot lkm also for persistent mode
- Unicornafl
- Added powerPC support from unicorn/next
- rust bindings!
- CMPLOG/Redqueen now also works for MMAP sharedmem
- ensure shmem is released on errors
- we moved radamsa to be a custom mutator in ./custom_mutators/. It is not
compiled by default anymore.
- allow running in /tmp (only unsafe with umask 0)
- persistent mode shared memory testcase handover (instead of via
files/stdin) - 10-100% performance increase
- General support for 64 bit PowerPC, RiscV, Sparc etc.
- fix afl-cmin.bash
- slightly better performance compilation options for afl++ and targets
- fixed afl-gcc/afl-as that could break on fast systems reusing pids in
the same second
- added lots of dictionaries from oss-fuzz, go-fuzz and Jakub Wilk
- added former post_library examples to examples/custom_mutators/
- Dockerfile upgraded to Ubuntu 20.04 Focal and installing llvm 11 and
gcc 10 so afl-clang-lto can be build
