.. _version_3.2.7:
=============
Version 3.2.7
=============
Released on 2019/04/09.
.. NOTE::
If you are upgrading a cluster, you must be running CrateDB 2.0.4 or higher
before you upgrade to 3.2.7.
We recommend that you upgrade to the latest 3.1 release before moving to
3.2.7.
If you want to perform a `rolling upgrade`_, your current CrateDB version
number must be at least :ref:`version_3.2.0`. Any upgrade from a version
prior to this will require a `full restart upgrade`_.
When restarting, CrateDB will migrate indexes to a newer format. Depending
on the amount of data, this may delay node start-up time.
Please consult the :ref:`version_3.0.0_upgrade_notes` before upgrading.
.. WARNING::
Tables that were created prior to upgrading to CrateDB 2.x will not
function with 3.2 and must be recreated before moving to 3.2.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`_.

Fixes
-----
- Fixed an issue that could cause :ref:`window functions <window-functions>` to
compute incorrect results if multiple window functions with different window
definitions were used.
- Fixed an issue that could cause a query with window functions and limit to
return too few rows or have the window functions compute wrong results.
- Fixed an issue that would cause a ``ClassCastException`` for queries ordered
by a window function.
- Fix quoting of identifiers that contain leading digits or spaces when
printing relation or column names.
