+Previously, if and only if a user-defined property was declared prior to
+the compilation of the regular expression pattern that contains it, its
+definition was used instead of any official Unicode property with the
+same name. Now, it always overrides the official property. This
+change could break existing code that relied (likely unwittingly) on the
+previous behavior. Without this fix, if Unicode released a new version
+with a new property that happens to have the same name as the one you
+had long been using, your program would break when you upgraded to a
+perl that used that new Unicode version. See L<perlunicode/User-Defined
