+\item The old \module{regex} and \module{regsub} modules, which have been 
+deprecated ever since Python 2.0, have finally been deleted.

+\item The \file{lib-old} directory,

+\module{ni}, was also deleted. \file{lib-old} wasn't on the default

+\code{sys.path}, this removal shouldn't affect your code.

 \item The \module{socket} module now supports \constant{AF_NETLINK}

+\item Evan Jones's patch to obmalloc, first described in a talk
+at PyCon DC 2005, was applied. Python 2.4 allocated small objects in
+256K-sized arenas, but never freed arenas. With this patch, Python
+will free arenas when they're empty. The net effect is that on some
+platforms, when you allocate many objects, Python's memory usage may
+actually drop when you delete them, and the memory may be returned to
+the operating system. (Implemented by Evan Jones, and reworked by Tim
+Peters.)
