Documentation
The glossary entry for method resolution order refers and links to the 2.3 release of python (at the following link: https://www.python.org/download/releases/2.3/mro/) for extra information about the method resolution order algorithm. But clicking on this link redirects to the generic download page for python releases, presumably because 2.3 is no longer available for download. The link has been present in the documentation since the method resolution order entry has been added (which, as far as I can tell, is version 3.2)
