+### Changed
+
+* Fixed a fuzzing performance issue where libfuzzer could unnecessarily spend
+  time exploring all the ways that an `Arbitrary` implementation could fail to
+  construct an instance of itself because the fuzzer provided too few bytes. See
+  https://github.com/rust-fuzz/libfuzzer/issues/59 for details.
