-A few performance enhancements have been added:
-
-* The garbage collector now performs better when many objects are
-  being allocated without deallocating any.  A full garbage collection
-  pass is only performed when the middle generation has been collected
-  10 times and when the number of survivor objects from the middle
-  generation exceeds 10% of the number of objects in the oldest

-  (Suggested by Martin von Loewis and implemented by Antoine Pitrou;

-
-* The garbage collector tries to avoid tracking simple containers which
-  can't be part of a cycle. As of now, this is true for tuples and dicts
-  containing atomic types (such as ints, strings, etc.). Transitively, a dict
-  containing tuples of atomic types won't be tracked either. This helps bring
-  down the individual cost of each garbage collection, since it decreases the
-  number of objects to be considered and traversed by the collector.
-
-  To help diagnosing this optimization, a new function in the :mod:`gc`

+  The :class:`namedtuple` class now has an optional *rename* parameter.
+  If *rename* is True, field names that are invalid because they've
+  been repeated or that aren't legal Python identifiers will be
+  renamed to legal names that are derived from the field's
+  position within the list of fields:
+

+
+* New method: the :class:`Decimal` class gained a
+  :meth:`from_float` class method that performs an exact conversion
+  of a floating-point number to a :class:`Decimal`.
+  Note that this is an **exact** conversion that strives for the
+  closest decimal approximation to the floating-point representation's value;
+  the resulting decimal value will therefore still include the inaccuracy,
+  if any.
+  For example, ``Decimal.from_float(0.1)`` returns
+  ``Decimal('0.1000000000000000055511151231257827021181583404541015625')``.
+  (Implemented by Raymond Hettinger; :issue:`4796`.)
+
+* A new function in the :mod:`gc` module, :func:`is_tracked`, returns
+  True if a given instance is tracked by the garbage collector, False
+  otherwise. (Contributed by Antoine Pitrou; :issue:`4688`.)
+
 * The :mod:`gzip` module's :class:`GzipFile` now supports the context
   management protocol, so you can write ``with gzip.GzipFile(...) as f: ...``.
   (Contributed by Hagen Fuerstenau; :issue:`3860`.)
+  It's now possible to override the modification time
+  recorded in a gzipped file by providing an optional timestamp to
+  the constructor.  (Contributed by Jacques Frechet; :issue:`4272`.)
 
 * The :class:`io.FileIO` class now raises an :exc:`OSError` when passed
   an invalid file descriptor.  (Implemented by Benjamin Peterson;
   :issue:`4991`.)
 
+* New function: ``itertools.compress(*data*, *selectors*)`` takes two
+  iterators.  Elements of *data* are returned if the corresponding
+  value in *selectors* is True::
+
+    itertools.compress('ABCDEF', [1,0,1,0,1,1]) =>
+      A, C, E, F
+
+  New function: ``itertools.combinations_with_replacement(*iter*, *r*)``
+  returns all the possible *r*-length combinations of elements from the
+  iterable *iter*.  Unlike :func:`combinations`, individual elements
+  can be repeated in the generated combinations::
+
+    itertools.combinations_with_replacement('abc', 2) =>
+      ('a', 'a'), ('a', 'b'), ('a', 'c'),
+      ('b', 'b'), ('b', 'c'), ('c', 'c')
+
+  Note that elements are treated as unique depending on their position
+  in the input, not their actual values.
+
+  The :class:`itertools.count` function now has a *step* argument that
+  allows incrementing by values other than 1.  :func:`count` also
+  now allows keyword arguments, and using non-integer values such as
+  floats or :class:`Decimal` instances.  (Implemented by Raymond
+  Hettinger; :issue:`5032`.)
+
+  :func:`itertools.combinations` and :func:`itertools.product` were
+  previously raising :exc:`ValueError` for values of *r* larger than
+  the input iterable.  This was deemed a specification error, so they
+  now return an empty iterator.  (Fixed by Raymond Hettinger; :issue:`4816`.)
+
+* The :mod:`json` module was upgraded to version 2.0.9 of the
+  simplejson package, which includes a C extension that makes
+  encoding and decoding faster.
+  (Contributed by Bob Ippolito; :issue:`4136`.)
+
+  To support the new :class:`OrderedDict` type, :func:`json.load`
+  now has an optional *object_pairs_hook* parameter that will be called
+  with any object literal that decodes to a list of pairs.
+  (Contributed by Raymond Hettinger; :issue:`5381`.)
+
 * The :mod:`pydoc` module now has help for the various symbols that Python
   uses.  You can now do ``help('<<')`` or ``help('@')``, for example.
