--------------
Version 1.26b:
--------------
- Added total execs/sec stat for afl-whatsup.
- afl-cmin now auto-selects between cp or ln. Based on feedback from
Even Huus.
- Fixed a typo. Thanks to Jakub Wilk.
- Made afl-gotcpu a bit more accurate by using getrusage instead of
times. Thanks to Jakub Wilk.
- Fixed a memory limit issue during the build process on NetBSD-current.
Reported by Thomas Klausner.
--------------
Version 1.25b:
--------------
- Introduced afl-whatsup, a simple tool for querying the status of
local synced instances of afl-fuzz.
- Added -x compiler to clang options on Darwin. Suggested by Filipe
Cabecinhas.
- Improved exit codes for afl-gotcpu.
- Improved the checks for -m and -t values in afl-cmin. Bug report
from Evan Huus.
--------------
Version 1.24b:
--------------
- Introduced afl-getcpu, an experimental tool to empirically measure
CPU preemption rates. Thanks to Jakub Wilk for the idea.
--------------
Version 1.23b:
--------------
- Reverted one change to afl-cmin that actually made it slower.
--------------
Version 1.22b:
--------------
- Reworked afl-showmap.c to support normal options, including -o, -q,
-e. Also added support for timeouts and memory limits.
- Made changes to afl-cmin and other scripts to accommodate the new
semantics.
- Officially retired AFL_EDGES_ONLY.
- Fixed another typo in afl-tmin, courtesy of Jakub Wilk.
--------------
Version 1.21b:
--------------
- Graduated minimize_corpus.sh to afl-cmin. It is now a first-class
utility bundled with the fuzzer.
- Made significant improvements to afl-cmin to make it faster, more
robust, and more versatile.
- Refactored some of afl-tmin code to make it a bit more readable.
- Made assorted changes to the doc to document afl-cmin and other stuff.
--------------
Version 1.20b:
--------------
- Added AFL_DUMB_FORKSRV, as requested by Jakub Wilk. This works only
in -n mode and allows afl-fuzz to run with "dummy" fork servers that
don't output any instrumentation, but follow the same protocol.
- Renamed AFL_SKIP_CHECKS to AFL_SKIP_BIN_CHECK to make it at least
somewhat descriptive.
- Switched to using clang as the default assembler on MacOS X to work
around Xcode issues with newer builds of clang. Testing and patch by
Nico Weber.
- Fixed a typo (via Jakub Wilk).
--------------
Version 1.19b:
--------------
- Improved exec failure detection in afl-fuzz and afl-showmap.
- Improved Ctrl-C handling in afl-showmap.
- Added afl-tmin, a handy instrumentation-enabled minimizer.
--------------
Version 1.18b:
--------------
- Fixed a serious but short-lived bug in the resumption behavior introduced
in version 1.16b.
- Added -t nn+ mode for soft-skipping timing-out paths.
--------------
Version 1.17b:
--------------
- Fixed a compiler warning introduced in 1.16b for newer versions of GCC.
Thanks to Jakub Wilk and Ilfak Guilfanov.
- Improved the consistency of saving fuzzer_stats, bitmap info, and
auto-dictionaries when aborting fuzzing sessions.
- Made several noticeable performance improvements to deterministic arith
and known int steps.
--------------
Version 1.16b:
--------------
- Added a bit of code to make resumption pick up from the last known
offset in the queue, rather than always rewinding to the start. Suggested
by Jakub Wilk.
- Switched to tighter timeout control for slow programs (3x rather than
5x average exec speed at init).
--------------
Version 1.15b:
--------------
- Added support for AFL_NO_VAR_CHECK to speed up resumption and inhibit
variable path warnings for some programs.
- Made the trimmer run even for variable paths, since there is no special
harm in doing so and it can be very beneficial if the trimming still
pans out.
- Made the UI a bit more descriptive by adding "n/a" instead of "0" in a
couple of corner cases.
--------------
Version 1.14b:
--------------
- Added a (partial) dictionary for JavaScript.
- Added AFL_NO_CPU_RED, as suggested by Jakub Wilk.
- Tweaked the havoc scaling logic added in 1.12b.
