=================================

* Don't use threading stuff if perl wasn't build with threading support.
  [Wim Lewis]
* Don't create unique package names for types that have an ancestor which has
  the "don't warn about unregistered subclasses" bit set.  Use this ancestor's
  package name to represent affected types.  [muppet]
