Core and builtins
-----------------
+- PEP 338: -m command line switch now delegates to runpy.run_module
+ allowing it to support modules in packages and zipfiles
+
- On Windows, .DLL is not an accepted file name extension for
extension modules anymore; extensions are only found if they
end in .PYD.
Library
-------
+- PEP 338: new module runpy defines a run_module function to support
+ executing modules which provide access to source code or a code object
+ via the PEP 302 import mechanisms.
+
- The email module's parsedate_tz function now sets the daylight savings
flag to -1 (unknown) since it can't tell from the date whether it should
be set.
