Antoine Pitrou added the comment:
I don't think it's useful to tell people:
- use codecs.open() on Python 2.4, 2.5, 2.6
- use io.open() on Python 2.7 (io is too slow on 2.6 to be a real alternative to codecs.open())
- use open() on Python 3.4+
Instead we can tell them to use io.open() on all versions from 2.7 and upwards. 2.6 is dead and won't receive any documentation updates anyway.
