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.
