Version 4.1.6

Released on 2020-06-08.


If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 4.1.6.

We recommend that you upgrade to the latest 4.0 release before moving to 4.1.6.

A rolling upgrade to 4.1.6 from 4.0.2+ is supported.

Before upgrading, you should back up your data.

See the Version 4.1.0 release notes for a full list of changes in the 4.1 series.


  • Fixed an issue that prevented CrateDB from detecting changes to the SSL keystore or truststore if one the paths is a symlink.

  • Fixed an issue that could prevent updating settings that depend on other settings. For example "cluster.routing.allocation.disk.watermark.low"

  • Fixed an issue that caused the ANALYZE statement to fail if there are tables with object arrays in the cluster.

  • Fixed a performance issue that can lead to queries like SELECT text_column FROM tbl GROUP BY 1 to run more than 150% faster.
