Cassandra 4.0 GA was released on 26th July 2021. It’s a great version, with lots of new features and optimisations! But… what happens to the older versions?

Last time I checked, some months ago, apparently some old versions users would need to upgrade quickly, because their versions would reach their EOL in 6 months from the release of Cassandra 4.0 GA. But now that 4.0 is released I’ve checked again, and…

Cassandra 2.1 is unsupported already.
Cassandra 2.2 will reach its EOL on April 2022, currently only critical bugs are fixed. Note that vendors definition of critical rarely matches users definition.
Cassandra 3 will reach its EOL on April 2022, currently it’s supported.

If you use Cassandra 2.* you already in trouble, though if you use 2.2 your troubles are moderated. In all cases, the time to upgrade is short, you need to act now.
