 Most operators only took account of the minimum bounding rectangles (MBR) of the geometries, and not the geometries themselves.
 
 This changed in version 5.6.1 were MySQL introduced `ST_*` spatial operators.
-The dialects `MySQLSpatial56Dialect` and `MySQLSpatial5InnoDBDialect` use these newer, more precise operators.
+The dialect `MySQLSpatial56Dialect` uses these newer, more precise operators.
 
 These dialects may therefore produce results that differ from that of the other spatial dialects.
