EducationProgram extension shouldn't use the deprecated window.gM function. It's about to be removed.
extensions/EducationProgram/resources/ep.enlist.js: 262: this.$dialog.append( $( '<p>' ).text( gM( extensions/EducationProgram/resources/ep.js: 48: return gM.apply( this, arguments ); extensions/EducationProgram/resources/ep.pager.js: 220: alert( window.gM( 'ep-pager-delete-selected-fail', ids.length ) );
