Link from old releases to new releases. #24
Description
It should be great to display a message with a link on old releases pointing to new releases.
I can imagine a banner like:
This document is about an unsupported version of Python. Please check the doc about Python 3.7.
With the "Python 3.7" text being a link to the right page on /3/, so both user and search engines can follow it.
Already been discussed here: https://bugs.python.org/issue35435
