   - all compilers combined to afl-cc which emulates the previous ones
   - afl-llvm/gcc-rt.o merged into afl-compiler-rt.o
   - afl-fuzz
-    - memory limits are now disabled by default, set them with -m if required
+    - not specifying -M or -S will now auto-set "-S default"
     - deterministic fuzzing is now disabled by default and can be enabled with
       -D. It is still enabled by default for -M.
     - a new seed selection was implemented that uses weighted randoms based on
       a schedule performance score, which is much better that the previous
       walk the whole queue approach. Select the old mode with -Z (auto enabled
       with -M)
-    - rpc.statsd support, for stats and charts, by Edznux, thanks a lot!
     - Marcel Boehme submitted a patch that improves all AFFast schedules :)
-    - not specifying -M or -S will now auto-set "-S default"
+    - the default schedule is now FAST
+    - memory limits are now disabled by default, set them with -m if required
+    - rpc.statsd support, for stats and charts, by Edznux, thanks a lot!
     - reading testcases from -i now descends into subdirectories
     - allow the -x command line option up to 4 times
     - loaded extras now have a duplication protection
