* :class:`uuid.UUID` now uses ``__slots__`` to reduce its memory footprint.
+* Improved performance of :func:`operator.itemgetter` by 33%. Optimized
+ argument handling and added a fast path for the common case of a single
+ non-negative integer index into a tuple (which is the typical use case in
+ the standard library). (Contributed by Raymond Hettinger in

+* Sped-up field lookups in :func:`collections.namedtuple`. They are now more
+ than two times faster, making them the fastest form of instance variable
+ lookup in Python. (Contributed by Raymond Hettinger, Pablo Galindo, and
+ Serhiy Storchaka in :issue:`32492`.)

* The :class:`list` constructor does not overallocate the internal item buffer
if the input iterable has a known length (the input implements ``__len__``).
This makes the created list 12% smaller on average. (Contributed by Pablo
