This PEP describes the packages and modules in the standard
library which should remain backward compatible with previous
versions of Python.
versions of Python. If a package is not listed here, then it need
only remain compatible with the version of Python it is
distributed with.
Rationale

authors must add a comment at the top of each file documenting
the compatibility requirement.
When a major version of Python is released, a CVS branch is
created for continued maintenance and bug fix releases. A package
version on a branch may have a different compatibility requirement
than the same package on the trunk (i.e. current bleeding-edge
development). Where appropriate, these branch compatibilities are
listed below.
