Version 2.3.8

Released on 2018/05/16.


If you are upgrading a cluster, you must be running CrateDB Version 1.1.3 or higher before you upgrade to 2.3.8.

If you want to perform a rolling upgrade, your current CrateDB version number must be at least Version 2.3.0. Any upgrade from a version prior to this will require a full restart upgrade.


Before upgrading, you should back up your data.
