.. _version_3.1.3:
=============
Version 3.1.3
=============
Released on 2018/11/19.
.. NOTE::
If you are upgrading a cluster, you must be running CrateDB 2.0.4 or higher
before you upgrade to 3.1.3.
We recommend that you upgrade to the latest 3.0 release before moving to
3.1.3.
If you want to perform a `rolling upgrade`_, your current CrateDB version
number must be at least :ref:`version_3.1.1`. Any upgrade from a version
prior to this will require a `full restart upgrade`_.
.. WARNING::
Tables that were created prior to upgrading to CrateDB 2.x will not
function with 3.1 and must be recreated before moving to 3.1.x.
You can recreate tables using ``COPY TO`` and ``COPY FROM`` while running a
2.x release into a new table, or by `inserting the data into a new table`_.
Before upgrading, you should `back up your data`_.

Changelog
=========
Fixes
-----
- Updated the Admin UI to 1.10.4 which includes the following fixes:
- Fixed an issue that caused the cluster and node checks to not be refreshed
when clicking on the ``refresh`` icon.
- Fixed an issue that caused the Twitter importer to redirect to ``/``
instead of ``/help``.
- Fixed the navigation component to allow opening URLs in new tabs.
- Fixed a race condition that could allow the creation of partitions with a
different schema than other partitions within the same partitioned table.
- Changed the ``user`` HDFS repository parameter to ``security.principal``, as
that is the parameter used by the underlying ``repository-hdfs`` plugin.
- Removed the ``conf_location`` HDFS repository parameter as it is no longer
used.
- Fixed an issue that caused zombie entries in ``sys.jobs`` if the
``fetchSize`` functionality of PostgreSQL wire protocol based clients is
used.
- Fixed a memory leak in the ``MQTT`` ingest service.
- Fixed a memory leak that could occur with clients connecting via PostgreSQL
protocol and invoking read queries with statements containing
:ref:`expressions <gloss-expression>` that would fail (such as ``1 / 0``).
- Fixed an issue in the PostgreSQL wire protocol that could result in nodes
crashing with ``OutOfMemoryError`` if clients queried very large tables
without specifying the fetch size.
- Fixed an issue that caused missing privilege errors if table aliases were
used.
