Update to 0.80b:

--------------
Version 0.80b:
--------------

  - Added a check for $PATH-induced loops. Spotted by Kartik Agaram.

  - Added AFL_KEEP_ASSEMBLY.

  - Override for AFL_USE_ASAN if set at afl compile time. Requested by
    Hanno Boeck.

--------------
Version 0.79b:
--------------

  - Minor adjustment to path skipping logic.

  - Several documentation updates to reflect the changes made yesterday.

--------------
Version 0.78b:
--------------

  - CPU governor check. Problem spotted by Joe Zbiciak.

  - Favored paths are now selected strictly based on new edges, not hit
    counts. This speeds up the first pass by a factor of 3-6x without
    significantly impacting ultimate coverage (tested with libgif, libpng,
    libjpeg).

    It also allows some performance & memory usage improvements by making
    some of the in-memory bitmaps much smaller.

  - Multiple significant performance improvements to bitmap checking functions,
    plus a switch to a faster hash.

  - Owing largely to these optimizations, bitmap size is bumped to 64 kB
    and a warning is added to detect older binaries that rely on smaller
    bitmaps.

--------------
Version 0.77b:
--------------

  - Added AFL_SKIP_CHECKS to bypass binary checks when really warranted.
    Requested by Jakub Wilk.

  - Typo fixes.

  - Warning for runs that are aborted early on.

--------------
Version 0.76b:
--------------

  - Another signal handling fix for Solaris. Submitted by Martin Carpenter.

--------------
Version 0.75b:
--------------

  - A slightly more "elegant" kludge for the %llu glitch (see types.h).

  - CPU load warnings relaxed a bit.

--------------
Version 0.74b:
--------------

  - More responsive exec speed averages and better UI speed scaling.

  - Fix for interrupted reads on Solaris. Submitted by Martin Carpenter.

--------------
Version 0.73b:
--------------

  - Fix a stray memcpy() instead of memmove() on overlapping buffers.
    Mostly harmless but still dumb. Spotted thanks to David Higgs.

--------------
Version 0.72b:
--------------

  - Map size bumped up to 32k. You may want to recompile instrumented
    binaries (but nothing horrible will happen if you don't).

  - Huge performance improvements for bit-counting functions.

  - Default optimizations now include -funroll-loops. This should have
    interesting effects on the instrumentation. Frankly, I'm just going to
    ship it and see what happens next. I have a good feeling about this.

  - Fix for stack alignment crash on MacOS X 10.10; looks like the
    rhetorical question in the comments in afl-as.h has been answered.
    Spotted by Mudge Zatko.

--------------
Version 0.71b:
--------------

  - A fix for the nonsensical MacOS ELF check. Spotted by Mudge Zatko.

  - Improvements to ASAN checks.

--------------
Version 0.70b:
--------------

  - Explicit detection of ASAN.

  - Patches to compile on Solaris. Contributed by Martin Carpenter.

--------------
Version 0.69b:
--------------

  - Improved detection of non-instrumented binaries.

  - Crash counter in -C mode is now accurate.

  - Fix for an obscure install bug that made afl-as non-functional with the tool
    installed to /usr/bin instead of /usr/local/bin. Found by Florian Kiersch.

  - Fix for a cosmetic SIGFPE when Ctrl-C is pressed while the fork server
    is spinning up.

--------------
Version 0.68b:
--------------

  - Crash exploration mode! Woot!

--------------
Version 0.67b:
--------------

  - Several more typos fixed, the project is now cartified 100% typo-free.
    Thanks to Thomas Jarosch and Jakub Wilk.

  - Write fuzzer_stats early on.

  - Minor fix for MacOS X operation as root. Spotted by Tobias Ospelt.

  - Make it possible to override -O3. Patch by Jakub Wilk.

--------------
Version 0.66b:
--------------

  - Fix for a very obscure issue with build systems that use gcc as an assembler
    for hand-written .s files, confusing afl-as. Affected nss. Reported by
    Hanno Boeck.

  - Fix for a bug when cleaning up synchronized fuzzer output dirs. Reported by
    Thomas Jarosch.
