+Synapse 1.45.0 (2021-10-19)
+===========================
+
+No functional changes since Synapse 1.45.0rc2.
+
+Known Issues
+------------
+
+- A suspected [performance regression](https://github.com/matrix-org/synapse/issues/11049) which was first reported after the release of 1.44.0 remains unresolved.
+
+  We have not been able to identify a probable cause. Affected users report that setting up a federation sender worker appears to alleviate symptoms of the regression.
+
+Improved Documentation
+----------------------
+
+- Reword changelog to clarify concerns about a suspected performance regression in 1.44.0. ([\#11117](https://github.com/matrix-org/synapse/issues/11117))
