[Bug #780231] One of the changes described in the 2.3 "What's New" document

   actually occurred in 2.2.  Move the description to whatsnew22.tex.

[Bugfix candidate -- I'll backport to 2.3 (another 2.2 bugfix seems unlikely)

+\item The C-level interface to the garbage collector has been changed
+to make it easier to write extension types that support garbage
+collection and to debug misuses of the functions.
+Various functions have slightly different semantics, so a bunch of
+functions had to be renamed.  Extensions that use the old API will
+still compile but will \emph{not} participate in garbage collection,
+so updating them for 2.2 should be considered fairly high priority.
+
+To upgrade an extension module to the new API, perform the following
+steps:
+
+\begin{itemize}
+
+\item Rename \cfunction{Py_TPFLAGS_GC} to \cfunction{PyTPFLAGS_HAVE_GC}.
+
+\item Use \cfunction{PyObject_GC_New} or \cfunction{PyObject_GC_NewVar} to
+allocate objects, and \cfunction{PyObject_GC_Del} to deallocate them.
+
+\item Rename \cfunction{PyObject_GC_Init} to \cfunction{PyObject_GC_Track} and
+\cfunction{PyObject_GC_Fini} to \cfunction{PyObject_GC_UnTrack}.
+
+\item Remove \cfunction{PyGC_HEAD_SIZE} from object size calculations.
+
+\item Remove calls to \cfunction{PyObject_AS_GC} and \cfunction{PyObject_FROM_GC}.

   \item A new \samp{et} format sequence was added to
   \cfunction{PyArg_ParseTuple}; \samp{et} takes both a parameter and
   an encoding name, and converts the parameter to the given encoding
