60: Added support for the SkippedEntityHandler, new in Expat 1.95.4.
61: Added support for namespace prefixes, which can be enabled by setting the
    "namespace_prefixes" attribute on the parser object.
65: Disable profiling changes for Python 2.0 and 2.1.
66: Update pyexpat to export the Expat 1.95.5 XML_GetFeatureList()
    information, and tighten up a type declaration now that Expat is using
    an incomplete type rather than a void * for the XML_Parser type.
67: Clarified a comment.
    Added support for XML_UseForeignDTD(), new in Expat 1.95.5.
68: Refactor to avoid partial duplication of the code to construct an
    ExpatError instance, and actually conform to the API for the exception
    instance as well.
69: Remove some spurious trailing whitespace.
    Add a special external-entity-ref handler that gets installed once a
    handler has raised a Python exception; this can cancel actual parsing
    earlier if there's an external entity reference in the input data
    after the the Python excpetion has been raised.
70: Untabify APPEND.
71: Backport PyMODINIT_FUNC for 2.2 and earlier.

When daylight time ends, an hour repeats on the local clock (for example,
in US Eastern, the clock jumps from 1:59 back to 1:00 again).  Times in
the repeated hour are ambiguous.  A tzinfo subclass that wants to play
with astimezone() needs to treat times in the repeated hour as being
standard time.  astimezone() previously required that such times be
treated as daylight time.  There seems no killer argument either way,
but Guido wants the standard-time version, and it does seem easier the
new way to code both American (local-time based) and European (UTC-based)
switch rules, and the astimezone() implementation is simpler.

was broken because new-in-2.3 code added a tp_as_mapping slot to tuples.
Repaired that.

Added basic docs to check_recursion().

The code that intended to exempt tuples and strings was also broken here,

can't know whether subclass instances are immutable.  This part (and this
part alone) is a bugfix candidate.

are applicable to 2.2.2.

Make the code slightly shorter, faster, and easier to
read.

* Eliminate unused DUP_TOPX code for x==1.
compile.c always generates DUP_TOP instead.

* Since only two cases remain for DUP_TOPX, replace
the switch-case with if-elseif.

* The in-lined integer compare does a CheckExact on
both arguments. Since the second is a little more
likely to fail, test it first.

* The switch-case for IS/IS_NOT and IN/NOT_IN can
separate the regular and inverted cases with no
additional work. For all four paths, saves a test and
jump.

The Py2.3 updates to the pyclbr module return both Class and Function
objects.  The IDLE ClassBrowser module only knew about Class and could
not handle objects which did not define "super".

Fixed by adding a guard.
