Log message:
pdated afl to 2.31b.

--------------
Version 2.31b:
--------------

  - Changed havoc cycle counts for a marked performance boost, especially
    with -S / -d. See the discussion of FidgetyAFL in:

    https://groups.google.com/forum/#!topic/afl-users/fOPeb62FZUg

    While this does not implement the approach proposed by the authors of
    the CCS paper, the solution is a result of digging into that research;
    more improvements may follow as I do more experiments and get more
    definitive data.

--------------
Version 2.30b:
--------------

  - Made minor improvements to persistent mode to avoid the remote
    possibility of "no instrumentation detected" issues with very low
    instrumentation densities.

  - Fixed a minor glitch with a leftover process in persistent mode.
    Reported by Jakub Wilk and Daniel Stender.

  - Made persistent mode bitmaps a bit more consistent and adjusted the way
    this is shown in the UI, especially in persistent mode.

--------------
Version 2.29b:
--------------

  - Made a minor #include fix to llvm_mode. Suggested by Jonathan Metzman.

  - Made cosmetic updates to the docs.

--------------
Version 2.28b:
--------------

  - Added "life pro tips" to docs/.

  - Moved testcases/_extras/ to dictionaries/ for visibility.

  - Made minor improvements to install scripts.

  - Added an important safety tip.

--------------
Version 2.27b:
--------------

  - Added libtokencap, a simple feature to intercept strcmp / memcmp and
    generate dictionary entries that can help extend coverage.

  - Moved libdislocator to its own dir, added README.

  - The demo in experimental/instrumented_cmp is no more.

--------------
Version 2.26b:
--------------

  - Made a fix for libdislocator.so to compile on MacOS X.

  - Added support for DYLD_INSERT_LIBRARIES.

  - Renamed AFL_LD_PRELOAD to AFL_PRELOAD.

--------------
Version 2.25b:
--------------

  - Made some cosmetic updates to libdislocator.so, renamed one env
    variable.

--------------
Version 2.24b:
--------------

  - Added libdislocator.so, an experimental, abusive allocator. Try
    it out with AFL_LD_PRELOAD=/path/to/libdislocator.so when running
    afl-fuzz.

Log message:
Updated afl to 2.23b.

--------------
Version 2.23b:
--------------

  - Improved the stability metric for persistent mode binaries. Problem
    spotted by Kurt Roeckx.

  - Made a related improvement that may bring the metric to 100% for those
    targets.

--------------
Version 2.22b:
--------------

  - Mentioned the potential conflicts between MSAN / ASAN and FORTIFY_SOURCE.
    There is no automated check for this, since some distros may implicitly
    set FORTIFY_SOURCE outside of the compiler's argv[].

  - Populated the support for AFL_LD_PRELOAD to all companion tools.

  - Made a change to the handling of ./afl-clang-fast -v. Spotted by
    Jan Kneschke.

Log message:
Updated afl to 2.21b.

--------------
Version 2.21b:
--------------

  - Added some crash reporting notes for Solaris in docs/INSTALL, as
    investigated by Martin Carpenter.

  - Fixed a minor UI mix-up with havoc strategy stats.

--------------
Version 2.20b:
--------------

  - Revamped the handling of variable paths, replacing path count with a
    "stability" score to give users a much better signal. Based on the
    feedback from Vegard Nossum.

  - Made a stability improvement to the syncing behavior with resuming
    fuzzers. Based on the feedback from Vegard.

  - Changed the UI to include current input bitmap density along with
    total density. Ditto.

  - Added experimental support for parallelizing -M.

Log message:
Updated afl to 2.19b.

--------------
Version 2.19b:
--------------

  - Made a fix to make sure that auto CPU binding happens at non-overlapping
    times.

Log message:
Updated afl to 2.18b.

The lowest currently recommended version is 2.18b.

--------------
Version 2.18b:
--------------

  - Made several performance improvements to has_new_bits() and
    classify_counts(). This should offer a robust performance bump with
    fast targets.

--------------
Version 2.17b:
--------------

  - Killed the error-prone and manual -Z option. On Linux, AFL will now
    automatically bind to the first free core (or complain if there are no
    free cores left).

  - Made some doc updates along these lines.

Log message:
Updated afl to 2.16b.

--------------
Version 2.16b:
--------------

  - Improved support for older versions of clang (hopefully without
    breaking anything).

  - Moved version data from Makefile to config.h. Suggested by
    Jonathan Metzman.

Log message:
Updated afl to 2.15b.

--------------
Version 2.15b:
--------------

  - Added a README section on looking for non-crashing bugs.

  - Added license data to several boring files. Contributed by
    Jonathan Metzman.

Log message:
Updated afl to 2.14b.

--------------
Version 2.14b:
--------------

  - Added FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION as a macro defined when
    compiling with afl-gcc and friends. Suggested by Kostya Serebryany.

  - Refreshed some of the non-x86 docs.

Log message:
Updated afl to 2.13b.

--------------
Version 2.13b:
--------------

  - Fixed a spurious build test error with trace-pc and llvm_mode/Makefile.
    Spotted by Markus Teufelberger.

  - Fixed a cosmetic issue with afl-whatsup. Spotted by Brandon Perry.

Log message:
Updated afl to 2.12b.

--------------
Version 2.12b:
--------------

  - Fixed a minor issue in afl-tmin that can make alphabet minimization less
    efficient during passes > 1. Spotted by Daniel Binderman.
