Research direction
The issue requires updating the default Cassandra version from v3 to v4 in two places: the cu cassandra.yaml configuration file located in the test/resources directory, and the 'Requirements' section in the cassandra.md documentation. First, find these files in the repository. In cu cassandra.yaml, change any references to Cassandra v3 to v4. In cassandra.md, update the requirements to specify Cassandra v4. After making changes, verify that the configuration is valid and the documentation reads correctly. No code changes beyond configuration and docs are needed.
