.. _version_5.2.11:
==============
Version 5.2.11
==============
Released on 2023-12-21.
.. NOTE::
If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher
before you upgrade to 5.2.11.
We recommend that you upgrade to the latest 5.1 release before moving to
5.2.11.
A rolling upgrade from 5.1.x to 5.2.11 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`_.

See the :ref:`version_5.2.0` release notes for a full list of changes in the
5.2 series.
Security Fixes
==============
- The HTTP transport will not trust any ``X-Real-IP`` header by default anymore.
This prevents a client from spoofing its IP address by setting these headers
and thus bypassing IP based authentication with is enabled by default for the
``crate`` superuser.
To keep allowing the ``X-Real-IP`` header to be trusted, you have to
explicitly enable it via the
:ref:`auth.trust.http_support_x_real_ip <auth.trust.http_support_x_real_ip>`
node setting.
Packaging Changes
=================
- The RPM and DEB packages changed slightly to unify the build process. The most
important change is that the ``crate`` service no longer automatically starts
after package installation, to allow changing the configuration first.
Other than that, the structure is now:
- ``bin``, ``jdk`` and ``lib`` are installed into ``/usr/share/crate``. In the RPM
package this used to be in ``/opt/crate``.
- The home directory of the crate user is ``/usr/share/crate``
- changes, notice, license are in ``/usr/share/doc/crate``
- service file is in ``/usr/lib/systemd/system``
- The ``crate.yml`` configuration file is in ``/etc/crate/``
- The default environment configuration file at RPM packages changed to
``/etc/default/crate`` to be consistent with the DEB package. The old
location at ``/etc/sysconfig/crate`` is not supported anymore.
If you haven't made any significant configuration changes the new packages
should keep working out of the box.
Important for Debian and Ubuntu users: There is now a `new repository
<https://cdn.crate.io/downloads/debian/stable/>`_.
You'll have to update the repository configuration to install CrateDB newer
than 5.5.1.
This new repository keeps old CrateDB versions in the ``Package`` index and
also contains packages for ARM64.
