cause interpreter crashes; the only change in Python 2.5.4 relative
to 2.5.4 is the reversal of this patch.

2.5.4 is the last bug fix release of Python 2.5. Future 2.5.x releases
will only include security fixes. According to the release notes, about

See the release notes at the website (also available as Misc/NEWS in
the source distribution) for details of bugs fixed; most of them prevent
interpreter crashes (and now cause proper Python exceptions in cases
where the interpreter may have crashed before).

links for various platforms, release notes, and known issues, please
