=============
Version 2.1.2
=============

Released on 2017/08/08.

.. NOTE::

    If you are upgrading a cluster, you must be running CrateDB
    :ref:`version_1.1.3` or higher before you upgrade to 2.1.2.

    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`_.
