Version 5.7.4 - Unreleased


In development. 5.7.4 isn’t released yet. These are the release notes for the upcoming release.


If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 5.7.4.

We recommend that you upgrade to the latest 5.6 release before moving to 5.7.4.

A rolling upgrade from 5.6.x to 5.7.4 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.
