Version 4.0.2

Released on 2019/07/12.

Note

Please consult the Upgrade Notes before upgrading. Before upgrading to 4.0.2 you should be running a CrateDB cluster that is at least on 3.0.7.

An upgrade to Version 4.0.2 requires 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.

Fixes

  • Fixed an issue in the admin ui that prevented partitions from showing up in the table detail view.
  • Fixed an issue in the version handling that would prevent rolling upgrades to future versions of CrateDB.
  • Arithmetic operations now work on expressions of type timestamp without time zone, to make it consistent with timestamp with time zone.
