- updated to 4.21c
  * afl-fuzz
    - fixed a regression in afl-fuzz that resulted in a 5-10% performace loss
      do a switch from gettimeofday() to clock_gettime() which should be rather
      three times faster. The reason for this is unknown.
    - new queue selection algorithm based on 2 core years of queue data
      analysis. gives a noticable improvement on coverage although the results
      seem counterintuitive :-)
    - added AFL_DISABLE_REDUNDANT for huge queues
    - added `AFL_NO_SYNC` environment variable that does what you think it does
    - fix AFL_PERSISTENT_RECORD
    - run custom_post_process after standard trimming
    - prevent filenames in the queue that have spaces
    - minor fix for FAST schedules
    - more frequent stats update when syncing (todo: check performance impact)
    - now timing of calibration, trimming and syncing is measured seperately,
      thanks to @eqv!
    - -V timing is now accurately the fuzz time (without syncing), before
      long calibration times and syncing could result in now fuzzing being
      made when the time was already run out until then, thanks to @eqv!
    - fix -n uninstrumented mode when ending fuzzing
    - enhanced the ASAN configuration
    - make afl-fuzz use less memory with cmplog and fix a memleak
  * afl-cc:
    - re-enable i386 support that was accidently disabled
    - fixes for LTO and outdated afl-gcc mode for i386
    - fix COMPCOV split compare for old LLVMs
    - disable xml/curl/g_ string transform functions because we do not check
      for null pointers ... TODO
    - ensure shared memory variables are visible in weird build setups (forwarded request 1179645 from msmeissn)

- updated to 4.20c
  + 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 (forwarded request 1167801 from msmeissn)

    - compcov/LAF-intel:
      - floating point splitting bug fix by @hexcoder
      - due a bug in LLVM 17 integer splitting is disabled there!
      - when splitting floats was selected, integers were always split as well,
        fixed to require AFL_LLVM_LAF_SPLIT_COMPARES or _ALL as it should
    - dynamic instrumentation filtering for LLVM NATIVE, thanks @Mozilla!
      see utils/dynamic_covfilter/README.md
  - qemu_mode:
    - plugins are now activated by default and a new module is included that
      produces drcov compatible traces for lighthouse/lightkeeper/...
      thanks to @JRomainG to submitting!

- updated to 4.09c

      of exiting with an error message
    - allow -S/-M naming up to 50 characters (from 24)
    - CMPLOG:
      - added scale support (-l S)

    speed is in comparison to other setups. (forwarded request 1133736 from msmeissn)

- updated to 4.08c
  - afl-fuzz:
    - new mutation engine: mutations that favor discovery more paths are
      prefered until no new finds for 10 minutes then switching to mutations
      that favor triggering crashes. Modes and switch time can be configured
      with `-P`. Also input mode for the target can be defined with `-a` to
      be `text` or `binary` (defaults to `generic`)
    - new custom mutator that has the new afl++ engine (so it can easily
      incorporated into new custom mutators), and also comes with a standalone
      command line tool! See custom_mutators/aflpp/standalone/
    - display the state of the fuzzing run in the UI :-)
    - fix timeout setting if '+' is used or a session is restarted
    - -l X option to enable base64 transformation solving
    - allow to disable CMPLOG with '-c -' (e.g. afl.rs enforces '-c 0' on
      every instance which is counterproductive).
  - afl-cmin/afl-cmin.bash:
    - fixed a bug inherited from vanilla AFL where a coverage of
      map[123] = 11 would be the same as map[1123] = 1
    - warn on crashing inputs
    - adjust threads if less inputs than threads specified
  - afl-cc:
    - fixed an off-by-one instrumentation of iselect, hurting coverage a bit.
      Thanks to @amykweon for spotting and fixing!
    - @toka fixed a bug in laf-intel signed integer comparison splitting,
      thanks a lot!!
    - more LLVM compatability
  - frida_mode:
    - support for long form instrumentation on x86_x64 and arm64
    - renamed utils/get_symbol_addr.sh to utils/frida_get_symbol_addr.sh
  - qemu_mode:

      loaded libs after forkserver initialization (required by Mozilla)
  - afl-cc:

    - Persistent mode + QASAN support for ppc32 targets by @worksbutnottested
  - a new grammar custom mutator atnwalk was submitted by @voidptr127 !

  - Building now gives a build summary what succeeded and what not
  - afl-fuzz:
    - added AFL_NO_STARTUP_CALIBRATION to start fuzzing at once instead
      of calibrating all initial seeds first. Good for large queues
      and long execution times, especially in CIs.
    - default calibration cycles set to 7 from 8, and only add 5 cycles
      to variables queue items instead of 12.

      afl-clang-lto)
    - "saved timeouts" was wrong information, timeouts are still thrown

  - we renamed several UI and fuzzer_stat entries to be more precise,
    e.g. "unique crashes" -> "saved crashes", "total paths" ->
    "corpus count", "current path" -> "current item".
    This might need changing custom scripting!
  - Nyx mode (full system emulation with snapshot capability) has been

    -   removed indirections in rust callbacks
  - new binary-only fuzzing mode: coresight_mode for aarch64 CPUs :)
    thanks to RICSecLab submitting!
  - if instrumented libaries are dlopen()'ed after the forkserver you
    will now see a crash. Before you would have colliding coverage.
    We changed this to force fixing a broken setup rather then allowing
    ineffective fuzzing.
  - See docs/best_practices.md how to fix such setups.
