Version 5.4.3

Released on 2023-09-05.


If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 5.4.3.

We recommend that you upgrade to the latest 5.3 release before moving to 5.4.3.

A rolling upgrade from 5.3.x to 5.4.3 is supported. Before upgrading, you should back up your data.


Tables that were created before CrateDB 4.x will not function with 5.x and must be recreated before moving to 5.x.x.

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

  • Fixed a regression introduced with CrateDB 5.0.0 which can cause that some nested join queries using the hash-join algorithm will return empty results after table statistics have been collected and the join order is optimized.
