@@ -30,6 +30,7 @@ This release also includes changes from <<release-3-6-8, 3.6.8>>.
 * Deprecated public constructor for `SeedStrategy` in favor of builder pattern to be consistent with other strategies.
 * Allowed specification of a customized Spark app name.
 * Added getter method to `CoinStep` for its probability field.
+* Prevented decimal values from being parsed by `asDate()`.
 * Prevented specification of `Cardinality` to `option()` when not used in conjunction with `mergeV()`.
 * Exposed a mechanism for providers to customize the assertion of error messages in feature tests.
 * Attempted to detect JDK version for Gremlin Console to avoid problems with Java 17 if `neo4j-gremlin` is used.
