Terry J. Reedy <tjreedy@udel.edu> added the comment: A doc addition would seem like a good idea, so I am changing this to a doc issue for the current versions. Can you suggest specific text and a specific location to place it? A behavior change could only go into 3.2. I do not know who, if anyone, maintains zlib. A reference to the desired algorithm might be necessary. ---------- assignee: -> docs@python components: +Documentation -Library (Lib) nosy: +docs@python, tjreedy versions: +Python 2.6, Python 2.7, Python 3.1, Python 3.2 -Python 2.5 _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue5784> _______________________________________
