Version 2.1.5

Released on 2017/08/14.


If you are upgrading a cluster, you must be running CrateDB Version 1.1.3 or higher before you upgrade to 2.1.5.

If you want to perform a rolling upgrade, your current CrateDB version number must be Version 2.1.0. If you want to upgrade from a version prior to this, the upgrade will introduce all of the breaking changes listed for Version 2.1.0, and will require a full restart upgrade.

Consult the upgrade notes for Version 2.1.0 when upgrading.


Before upgrading, you should back up your data.

  • Fixed an issue that caused the setting in crate.yml file to be overridden by default name crate.

  • Fixed a null pointer exception when using explicit join conditions with fields which were not contained in the select list. For example:

    SELECT t3.z FROM t1
    JOIN t2 ON t1.a = t2.b
    JOIN t3 ON t2.b = t3.c
