 This release also includes changes from <<release-3-1-8, 3.1.8>>.
 
+* Fixed a bug in `RangeByIsCountStrategy`.
 * Allowed access to `InjectStep.injections` for `TraversalStrategy` analysis.
 * Exceptions that occur during result iteration in Gremlin Server will now 
return `SCRIPT_EVALUATION_EXCEPTION` rather than `SERVER_ERROR`.
 * `AddEdgeStep` attaches detached vertices prior to edge creation.
