+
+## Release notes
+
+
+* The wire-server now uses quorum queues for user notifications, communicating
+  with cells and for watching dead lettered user-notifications. These were
+  previously declared without any type making them "classic" RabbitMQ queues.
+
+  The transition is unfortunately not automatic. There are no official clients of
+  wire-server which use these queues, so in most cases there should only be two
+  queues which need to moved over:
+  1. cells_events
+  2. dead-user-notifications
+
+  If there are no other classic queues and no cells server is deployed, the steps
+  of upgrade are very simple:
+
+  1. Delete these queues
+  2. Deploy the new version of wire-server
+
+  Please note that rolling back this deployment would not be possible unless these
+  queues are deleted again.
+
+  In case there are other classic queues of format
+  `user-notifications.<user-id>.<client-id>` or if a cells server is configured,
+  then this ugprade would require some downtime. The steps are documented on
+  RabbitMQ blog:
+  https://www.rabbitmq.com/blog/2023/03/02/quorum-queues-migration#in-place-migration
