+==============================
+
+Bugfixes
+--------

+
+Deprecations and Removals
+-------------------------
+
+- Deprecate calling the `/register` endpoint with an unspecced `user` property for application services. ([\#15703](https://github.com/matrix-org/synapse/issues/15703))
+
+
+Internal Changes
+----------------
+
+- Speed up background jobs `populate_full_user_id_user_filters` and `populate_full_user_id_profiles`. ([\#15700](https://github.com/matrix-org/synapse/issues/15700))

+# Upgrading to v1.85.0
+
+## Application service registration with "user" property deprecation
+
+Application services should ensure they call the `/register` endpoint with a
+`username` property. The legacy `user` property is considered deprecated and
+should no longer be included.
+
+A future version of Synapse (v1.88.0 or later) will remove support for legacy
+application service login.
