Thank you for your question Manish!
If you notice the version compatibility matrix for the supported versions, there is "3.0+" under the "Apache Cassandra version" column which means DataStax Java Driver for Apache Cassandra™ version 3.0+ does have support for Apache Cassandra version 4.0.
Having said that,
3.0.1 was released long time ago (May 2, 2016-ish) and the latest 4.x version can be found
here, but if you want to stick with the 3.x series,
3.11.0 is the latest version that is available as of this writing.
Thanks & Regards!
