+# Synapse 1.106.0rc1 (2024-04-25)
+
+### Features
+
+- Send an email if the address is already bound to an user account. ([\#16819](https://github.com/element-hq/synapse/issues/16819))
+- Implement the rendezvous mechanism described by MSC4108. ([\#17056](https://github.com/element-hq/synapse/issues/17056))
+- Support delegating the rendezvous mechanism described MSC4108 to an external implementation. ([\#17086](https://github.com/element-hq/synapse/issues/17086))
+
+### Bugfixes
+
+- Add validation to ensure that the `limit` parameter on `/publicRooms` is non-negative. ([\#16920](https://github.com/element-hq/synapse/issues/16920))
+- Return `400 M_NOT_JSON` upon receiving invalid JSON in query parameters across various client and admin endpoints, rather than an internal server error. ([\#16923](https://github.com/element-hq/synapse/issues/16923))
+- Make the CSAPI endpoint `/keys/device_signing/upload` idempotent. ([\#16943](https://github.com/element-hq/synapse/issues/16943))
+- Redact membership events if the user requested erasure upon deactivating. ([\#17076](https://github.com/element-hq/synapse/issues/17076))
+
+### Improved Documentation
+
+- Add a prompt in the contributing guide to manually configure icu4c. ([\#17069](https://github.com/element-hq/synapse/issues/17069))
+- Clarify what part of message retention is still experimental. ([\#17099](https://github.com/element-hq/synapse/issues/17099))
+
+### Internal Changes
+
+- Use new receipts column to optimise receipt and push action SQL queries. Contributed by Nick @ Beeper (@fizzadar). ([\#17032](https://github.com/element-hq/synapse/issues/17032), [\#17096](https://github.com/element-hq/synapse/issues/17096))

+- Fix type annotation for `visited_chains` after `mypy` upgrade. ([\#17125](https://github.com/element-hq/synapse/issues/17125))
