See the :ref:`version_4.1.0` release notes for a full list of changes in the
4.1 series.
Fixes
=====
- Fixed an issue that prevented CrateDB from detecting changes to the SSL
``keystore`` or ``truststore`` if one the paths is a symlink.
- Fixed an issue that could prevent updating settings that depend on other
settings. For example ``"cluster.routing.allocation.disk.watermark.low"``
- Fixed an issue that caused the ``ANALYZE`` statement to fail if there are
tables with object arrays in the cluster.
- Fixed a performance issue that can lead to queries like ``SELECT text_column
FROM tbl GROUP BY 1`` to run more than 150% faster.
