+Known Issues
+------------
+
+- We are investigating [a performance issue](https://github.com/matrix-org/synapse/issues/11049) which was reported after the release of 1.44.0.
+- We are aware of [a bug](https://github.com/matrix-org/synapse/issues/11025) with the user directory when using application services. A second release candidate is expected which will resolve this.
