in_place_edit_for into which plugin?

The docs state that in_place_edit_for has been moved into a plugin for
Rails 2.0:

Module ActionController::Macros::InPlaceEditing::ClassMethods
"DEPRECATION WARNING: This method will become a separate plugin when
Rails 2.0 ships."

and the error messages seem to bear this out:

"undefined method `in_place_edit_for' for FaqQuestionController:Class"

Anyone know which plugin these have been moved to? Google seems to
come up empty.

On the same note, is there a master list of "was in Rails, now in
plugins" plugins anywhere?

Brilliant. Thank you sir.
