No, 23.10.2 is the latest cobia release.
24.04.0 is a different train (dragonfish).
There’s no need to immediately jump to dragonfish, 23.10.2 is fine. Dragonfish introduces some new features, but it’s still an early release .0.
You can check out the announcement thread for further information. How to upgrade should be covered in the other link I provided.
