I'm confused with [attr!=value]


In the docs it shows that [attr!=value] Matches elements that have the
specified attribute but not with a certain value.
(http://docs.jquery.com/Selectors/attributeNotEqual#attributevalue)
But in the recent changes in jQuery 1.3.1,it seems to revert.
(http://dev.jquery.com/changeset/6149)
So I just wonder whether it will change again?
thx~
