Additional notes

Pages are specified either by pageids or titles parameter. Individual revisions are specified by revids parameter. See API:Query .

{{ll|Manual:Slot|Slots}} can be specified with the rvslots parameter. When the parameter is not present, the API will only return information about the main slot.

When using parameters marked as (enum), titles= must have only one title listed.

This module couldn't be used as a generator prior to version 1.25.

Diff functionality of this module was deprecated in version 1.30 and got moved to API:Compare .

The code for this query is located on the git repository at ApiQueryRevisions.php.
