+        - shared references were not decoded correctly: instead of getting
+          multiple references to the same object, you got the same
+          reference to the same object, causing a number of issues. For
+          example, modifying the reference would modify all places the
+          reference was used, and encoding the decoded structure would
+          unshare the previously shared hashes, as trheir reference count
+          would be 1. Fixing this was rather involved, as perl lacks the
+          ability to easily swap or copy arrays and hashes.
+	- \0, \1, \undef do not work, and were not intended to ever work, as
+          special values, despite being mentioned in the documentation (reported
+          by nuclightq).
+        - new feature: allow_weak_cycles.

 	- fix a bug in validate_utf8 where we call perl's is_utf8_string with
           a lenght of zero for empty strings, but perl interprets that as
