Add the following new hooks to $templates, $fields and $fieldgroups: renameReady($item, $oldName, $newName); renamed($item, $oldName, $newName); Added the following new hooks to $fieldgroups: fieldAdded($fieldgroup, $field); fieldRemoved($fieldgroup, $field); Make template selectable for Page fields in InputfieldSelector, plus other minor updates.
