Hi Nick, Since autojunk was added in 2.7.1 (the docs of which do indicate this is the versionchanged tag), I think Terry may have left the tag in 3.2 out on purpose. That said, personally I don't know what the policy is regarding features added just in 3.2 and 2.7 (and didn't exist in 3.1) in this respect.

Features new in Python 3.2 that didn't exist in 3.1 should have a versionadded:: 3.2 tag.
