right version this time.  Thanks, Ping!
(This was from SF patch #494582, "\index -> \indexii" version.)

Utils.parseaddr('<>') -- i.e. on an empty address, returns the empty
string.  Built on rfc822, this used to return None.

Remove reference to this being a draft

    rfc822.AddressList incorrectly handles empty address.
    "<>" is converted to None and should be "".
    AddressList.__str__() fails on None.
    I got an email with such an address and my program
    failed processing it.

    Example:
    >>> import rfc822

    >>> rfc822.AddressList("<>").addresslist
    [('', None)]
    >>> str(rfc822.AddressList("<>"))
    Traceback (most recent call last):
    File "<stdin>", line 1, in ?
    File "/usr/lib/python2.1/rfc822.py", line 753, in __str__
    return ", ".join(map(dump_address_pair,
    self.addresslist))
    TypeError: sequence item 0: expected string, None found

[His solution: in the internal routine AddrlistClass.getrouteaddr(),
initialize adlist to "".]

- use repr instead of implied str for doubles
- updated version number to 1.0.0 (for 2.2 final)

Patch from Mark Hammond, plus code rearrangement and comments from me.
posix_do_stat():  Windows-specific code could try to free() stack
memory in some cases when a path ending with a forward or backward slash
was passed to os.stat().

metaclass, reported by Dan Parisien.

Objects that are instances of custom metaclasses, i.e. whose ob_type
is a subclass of PyType_Type, should be pickled the same as new-style
classes (objects whose ob_type is PyType_Type).  This can't be done
through the existing dispatch switches, and the __reduce__ trick
doesn't work for these, since it finds the unbound __reduce__ for
instances of the class (inherited from PyBaseObject_Type).  So check
explicitly using PyType_IsSubtype().

metaclass, reported by Dan Parisien.

extension, not the EXT one, as regen uses the python binary in the build
directory. Fixes #493959.

binascii_b2a_base64():  We didn't allocate enough buffer space for very
short inputs (e.g., a 1-byte input can produce a 5-byte output, but we
only allocated 2 bytes).  I expect that malloc overheads absorbed the
overrun in practice, but computing a correct upper bound is a very simple
change.

eval_frame():  Added asserts to the top of the eval loop, to verify
that the eval stack pointer is in bounds, plus some comments.

to prevent mysterious errors at shutdown due to "os.unlink" turning into
"None.unlink".

This way, when a socket object is deleted after the socket module has
already been zapped by module shutdown, we don't get annoying warnings
about exceptions in __del__ methods.

crashes.

If no external zip-utility is found, the archive is created by the
zipfile module, which behaves different now than in 2.1: if the
zip-file is created in the root directory if the distribution, it will
contain an (empty) version of itself.

This triggered the above bug - so it's better to create the zip-file
far away in the TMP directory.

This closes SF patch #494622.
