+- updated to 2.66c
+  - renamed blacklist/whitelist to ignorelist/instrumentlist ->
+    AFL_LLVM_INSTRUMENT_FILE and AFL_GCC_INSTRUMENT_FILE
+  - warn on deprecated environment variables
+  - afl-fuzz:
+     - -S secondary nodes now only sync from the main node to increase
+       performance, the -M main node still syncs from everyone. Added checks
+       that ensure exactly one main node is present and warn otherwise
+     - Add -D after -S to force a secondary to perform deterministic fuzzing
+     - If no main node is present at a sync one secondary node automatically
+       becomes a temporary main node until a real main nodes shows up
+     - Fixed a mayor performance issue we inherited from AFLfast
+     - switched murmur2 hashing and random() for xxh3 and xoshiro256**,
+       resulting in an up to 5.5% speed increase
+     - Resizing the window does not crash afl-fuzz anymore
+     - Ensure that the targets are killed on exit
+     - fix/update to MOpt (thanks to arnow117)
+     - added MOpt dictionary support from repo
+     - added experimental SEEK power schedule. It is EXPLORE with ignoring
+       the runtime and less focus on the length of the test case
+  - llvm_mode:
+    - the default instrumentation is now PCGUARD if the llvm version is >= 7,
+      as it is faster and provides better coverage. The original afl
+      instrumentation can be set via AFL_LLVM_INSTRUMENT=AFL. This is
+      automatically done when the instrument_file list feature is used. 
+    - PCGUARD mode is now even better because we made it collision free - plus
+      it has a fixed map size, so it is also faster! :)
+    - some targets want a ld variant for LD that is not gcc/clang but ld,
+      added afl-ld-lto to solve this
+    - lowered minimum required llvm version to 3.4 (except LLVMInsTrim, which
+      needs 3.8.0)
+    - instrument_file list feature now supports wildcards (thanks to sirmc)
+    - small change to cmplog to make it work with current llvm 11-dev
+    - added AFL_LLVM_LAF_ALL, sets all laf-intel settings
+    - LTO instrument_files functionality rewritten, now main, _init etc functions
+      need not to be listed anymore
+    - fixed crash in compare-transform-pass when strcasecmp/strncasecmp was
+      tried to be instrumented with LTO
+    - fixed crash in cmplog with LTO
+    - enable snapshot lkm also for persistent mode
+  - Unicornafl
+    - Added powerPC support from unicorn/next
+    - rust bindings!
+  - CMPLOG/Redqueen now also works for MMAP sharedmem
+  - ensure shmem is released on errors
+  - we moved radamsa to be a custom mutator in ./custom_mutators/. It is not
+    compiled by default anymore.
+  - allow running in /tmp (only unsafe with umask 0)
+  - persistent mode shared memory testcase handover (instead of via
+    files/stdin) - 10-100% performance increase
+  - General support for 64 bit PowerPC, RiscV, Sparc etc.
+  - fix afl-cmin.bash
+  - slightly better performance compilation options for afl++ and targets
+  - fixed afl-gcc/afl-as that could break on fast systems reusing pids in
+    the same second
+  - added lots of dictionaries from oss-fuzz, go-fuzz and Jakub Wilk
+  - added former post_library examples to examples/custom_mutators/
+  - Dockerfile upgraded to Ubuntu 20.04 Focal and installing llvm 11 and
+    gcc 10 so afl-clang-lto can be build
+
