There was a discussion recently about changing the Cassandra EOL policy on the users list [1], but it didn't really go anywhere. I wanted to ask here instead to clear up the status quo first. What's the current versioning policy? The tick-tock versioning blog post [2] states in passing that two major releases are maintained, but I have not found this as an official policy stated anywhere. For comparison, the Postgres project lays this out very clearly [3]. To be clear, I'm not looking for any official support, I'm just asking for clarification regarding the maintenance policy: if a critical bug or security vulnerability is found in version X.Y.Z, when can I expect it to be fixed in a bugfix patch to that major version, and when do I need to upgrade to the next major version.
