   * afl-fuzz
     - added AFL_DISABLE_REDUNDANT for huge queues
     - fix AFL_PERSISTENT_RECORD
+    - run custom_post_process after standard trimming
     - prevent filenames in the queue that have spaces
     - minor fix for FAST schedules
     - more frequent stats update when syncing (todo: check performance impact)

 Omitting any of three trimming methods will cause the trimming to be disabled
 and trigger a fallback to the built-in default trimming routine.
 
+**IMPORTANT** If you have a custom post process mutator that needs to be run
+after trimming, you must call it yourself at the end of your successful
+trimming!
