=============
Version 2.1.7
=============
Released on 2017/09/14.
.. NOTE::
If you are upgrading a cluster, you must be running CrateDB
:ref:`version_1.1.3` or higher before you upgrade to 2.1.7.
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`_.

=========
Fixes
-----
- Fixed an issue causing global aggregations with ``JOINs`` on virtual tables
(:ref:`subselects <gloss-subquery>`) which contain ``LIMIT`` to return
incorrect results. E.g.::
SELECT COUNT(*) FROM
(SELECT * FROM t1 ORDER BY a LIMIT 5) t1,
JOIN
t2
ON t1.a = t2.b
- Fixed an issue that caused an error when trying to create a table with a
:ref:`generated column expression <ddl-generated-columns-expressions>` of
type array.
- Fixed an issue that caused the ``account_user``-column to be empty in the
twitter tutorial plugin of the Admin UI.
- Fixed an issue when using ``GRANT``/``REVOKE``/``DENY`` statements on a
table with a custom schema set. The statements would result in permission
changed on the default ``doc`` schema.
- Fixed an issue with ``INNER`` and ``CROSS JOINS`` on more than 2 tables that
could result in a ``Iterator is not on a row`` error.
