.. _version_2.0.5:
=============
Version 2.0.5
=============
Released on 2017/07/11.
.. NOTE::
If you are upgrading a cluster, you must be running CrateDB
:ref:`version_1.1.3` or higher before you upgrade to 2.0.5.
If you want to perform a `rolling upgrade`_, your current CrateDB version
number must be :ref:`version_2.0.0`. If you want to upgrade from a version
prior to this, the upgrade will introduce all of the breaking changes
listed for :ref:`version_2.0.0`, and will require a `full restart
upgrade`_.
Consult the upgrade notes for :ref:`Version 2.0.0
<version_2.0.0_upgrade_notes>` when upgrading.
.. WARNING::
If you're using CrateDB's BLOB storage you should consult the `Upgrade
Notes`_.
Before upgrading, you should `back up your data`_.

Upgrade Notes
=============
Due to a bug introduced in :ref:`version_2.0.0` that can cause loss of BLOB
data, it is necessary to perform a `rolling upgrade`_ if you're running a
version >= 2.0.0 and < 2.0.4 and using BLOB tables.
Additionally, the number of replicas needs to be set to at least ``1`` for
*all* blob tables and you need to make sure that data is fully replicated
before continuing.
Only then you may upgrade one node after each other.
Changelog
=========
Fixes
-----
- Fixed an issue that caused an exception to be thrown when using ``COUNT(*)``
with a ``JOIN`` on 3 or more tables.
- Fixed a regression that caused queries with a ``GROUP BY`` on array columns,
which are wrapped in a :ref:`scalar function <scalar-functions>` to fail.
- Fixed an issue that caused an exception if a table that has been created
with CrateDB version <= 1.1 is modified using ``ALTER TABLE``.
