- 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    - fixes for LTO and outdated afl-gcc mode for i386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

- 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

- updated to 4.10c
  - 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. Thanks to @kdsjZh for the PR!
  - afl-cc:
    - large rewrite by @SonicStark which fixes a few corner cases, thanks!
    - LTO mode now requires llvm 12+
    - workaround for ASAN with gcc_plugin mode
  - instrumentation:
    - LLVM 18 support, thanks to @devnexen!
    - Injection (SQL, LDAP, XSS) fuzzing feature now available, see
      `instrumentation/README.injections.md` how to activate/use/expand.
    - 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 Nyx checkout (fixes a bug) and some QOL
  - updated the custom grammar mutator
  - document afl-cmin does not work on macOS (but afl-cmin.bash does)

- updated to 4.09c
  - afl-fuzz:
    - fixed the new mutation implementation for two bugs
    - added `AFL_FINAL_SYNC` which forces a final fuzzer sync (also for `-F`)
      before terminating.
    - added AFL_IGNORE_SEED_PROBLEMS to skip over seeds that time out instead
      of exiting with an error message
    - allow -S/-M naming up to 50 characters (from 24)
    - CMPLOG:
      - added scale support (-l S)
      - skip unhelpful insertions (u8)
    - added --version and --help command line parameters
    - fixed endless loop when reading malformed dictionaries
    - new custom mutator function: post_run - thanks to yangzao!
  - afl-whatsup:
    - detect instanced that are starting up and show them as such as not dead
    - now also shows coverage reached
    - option -m shows only very relevant stats
    - option -n will not use color in the output
  - instrumentation:
    - fix for a few string compare transform functions for LAF
    - we are instrumenting __cxx internal functions again. this might break
      a few targets, please report if so.
  - frida_mode:
    - fixes support for large map offsets
  - support for AFL_FUZZER_LOOPCOUNT for afl.rs and LLVMFuzzerTestOneInput
  - afl-cmin/afl-cmin.bash: prevent unneeded file errors
  - added new tool afl-addseeds that adds new seeds to a running campaign
  - added benchmark/benchmark.py if you want to see how good your fuzzing
    speed is in comparison to other setups.

- 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:

- updated to 4.07c
  - afl-fuzz:
    - reverse reading the seeds only on restarts (increases performance)

    - fallback to native LLVM PCGUARD if our PCGUARD is unavailable
    - fixed a crash in GCC CMPLOG
  - afl-showmap:
    - added custom mutator post_process and send support
    - add `-I filelist` option, an alternative to `-i in_dir`
