As you work on patches in JIRA you need to determine which branch to apply your patch to. 

Active Branches

Currently (May 2022August 2023) there are five six relevant branches to be familiar with:

• cassandra-3.0 (3.0)
• cassandra-3.11 (3.11)
• cassandra-4.0 (4.0)
• cassandra-4.1 (latest GA)
• cassandra-45.1 0 (frozen , pending releasew/waiver for Accord, Transactional Metadata work, and Vector search)
• trunk (next release)

cassandra-3.0 (apply) → cassandra-3.11 → cassandra-4.0 → cassandra-4.1 → cassandra-5.0 → trunk

A new feature or improvement would apply trunk only:

trunk (apply)
