  Adding the mixin as a superclass provides the full dictionary
  interface whenever the class defines \method{__getitem__},
! \method{__setitem__}, \method{__delitem__), and \method{keys}.

+ \item The \module{Tkinter} module now works with a thread-enabled 
+ version of Tcl.  Tcl's threading model requires that widgets only be
+ accessed from the thread in which they're created; accesses from
+ another thread can cause Tcl to panic.  For certain Tcl interfaces,
+ \module{Tkinter} will now automatically avoid this by marshalling a
+ command, passing it to the correct thread, and waiting for the results
+ when a widget is accessed from a different thread.  Other interfaces
+ can't be handled automatically but \module{Tkinter} will now raise an
+ exception on such an access so that you can at least find out about
+ the problem.  See
+ \url{http://mail.python.org/pipermail/python-dev/2002-December/031107.html}
+ for a more detailed explanation of this change.  (Implemented by
+ Martin von L\"owis.)

  \item Calling Tcl methods through \module{_tkinter} no longer 
  returns only strings. Instead, if Tcl returns other objects those
