.. _version_5.2.10:
==============
Version 5.2.10
==============
Released on 2023-10-12.
.. NOTE::
If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher
before you upgrade to 5.2.10.
We recommend that you upgrade to the latest 5.1 release before moving to
5.2.10.
A rolling upgrade from 5.1.x to 5.2.10 is supported.
Before upgrading, you should `back up your data`_.
.. WARNING::
Tables that were created before CrateDB 4.x will not function with 5.x
and must be recreated before moving to 5.x.x.
You can recreate tables using ``COPY TO`` and ``COPY FROM`` or by
`inserting the data into a new table`_.

5.2 series.
Fixes
=====
- Fixed an issue that caused privileges checks to be bypassed when using scalar
sub-selects in various clauses of a query: ``SELECT``, ``WHERE``, ``HAVING``,
etc.
- Fixed an issue that led to file not found errors when trying to restore a
snapshot that was taken after a table had been swapped. A new snapshot
must be taken to apply the fix and solve the issue. This issue was not fully
addressed with :ref:`version_5.2.9`.
