Upgrading Cassandra 3.11.14 → 4.1

Hi all,
     is upgrading Cassandra 3.11.14 → 4.1 supported, or is it better to 
follow the 3.11.14 → 4.0 → 4.1 path?

(I think it is okay as i found no record of deprecated old SSTable 
formats, but I couldn't manage to find any official documentation 
regarding upgrade paths… forgive me if it is around)

3.11.14 → 4.1 is supported.

It is recommended to go to the last patch version (i.e. 3.11.14) before the
major upgrade.
Make sure to ensure all sstables are upgraded to the current format before
performing the upgrade.
