[Python-Dev] Policy about old Python versions

[Batista, Facundo]

Sometimes, reviewing bugs, I found some ones referring problems about old
Python versions.

Is there a policy about supporting old Python versions? At some time an old
version becomes "deprecated"?

For example, an open bug about a problem of Python 2.1, that is solved in
Python 2.2 and subsequents, when should be closed?

Thank you!
