• Fixed installation of 'wxPerl' command on Mac OS X.
  
• Fixed running in the embedded case (still requires the
  application to call ExitMainLoop at the right places).
  
• Wrapped wxNavigationKeyEvent.
  
• Using die() in an event handler should not crash anymore
  (it might leak).
  
• Added Wx::PlWindow, to be used for custom controls.
  
• New (Windows-only) --mslu flag for Makefile.PL.
  
• Wx::NotebookSizer is now no longer needed and
  deprecated.
