+* Added new hooks, 'ApiQueryBaseBeforeQuery', 'ApiQueryBaseAfterQuery', and
+ 'ApiQueryBaseProcessRow', to make it easier for extensions to add 'prop' and
+ 'show' parameters to existing API query modules. A query module can enable
+ these hooks by passing an array for $hookData to ApiQueryBase::select() and
+ by calling ApiQueryBase->processRow() before adding a row's data to the
+ result.
