Version 4.0.5

Released on 2019/09/19.

Note

Please consult the Upgrade Notes before upgrading from CrateDB 3.x or earlier. Before upgrading to 4.0.5 you should be running a CrateDB cluster that is at least on 3.0.7.

We recommend that you upgrade to the latest 3.3 release before moving to 4.0.5.

If you want to perform a rolling upgrade, your current CrateDB version number must be at least Version 4.0.2. Any upgrade from a version prior to this will require a full restart upgrade.

When restarting, CrateDB will migrate indexes to a newer format. Depending on the amount of data, this may delay node start-up time.

Warning

Tables that were created prior CrateDB 3.x will not function with 4.x and must be recreated before moving to 4.x.x.

You can recreate tables using COPY TO and COPY FROM or by inserting the data into a new table.

Before upgrading, you should back up your data.
