+<p>This version introduces optional support for an <a href="https://github.com/matrix-org/synapse/pull/14464">improved user search dealing with Unicode characters</a>.</p>
+<p>If you want to take advantage of this feature you need to install PyICU,
+the ICU native dependency and its development headers
+so that PyICU can build since no prebuilt wheels are available.</p>
+<p>You can follow <a href="https://pypi.org/project/PyICU/">the PyICU documentation</a> to do so,
+and then do <code>pip install matrix-synapse[icu]</code> for a PyPI install.</p>
+<p>Docker images and Debian packages need nothing specific as they already
+include or specify ICU as an explicit dependency.</p>
