.. _version_2.1.5:
=============
Version 2.1.5
=============
Released on 2017/08/14.
.. NOTE::
If you are upgrading a cluster, you must be running CrateDB
:ref:`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 :ref:`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 :ref:`version_2.1.0`, and will require a `full restart upgrade`_.
Consult the upgrade notes for :ref:`Version 2.1.0
<version_2.1.0_upgrade_notes>` when upgrading.
.. WARNING::
Before upgrading, you should `back up your data`_.

Fixes
-----
- Fixed an issue that caused the ``cluster.name`` 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
