Synapse 1.79.0rc2 (2023-03-13)
==============================
Bugfixes
--------
- Fix a bug introduced in Synapse 1.79.0rc1 where attempting to register a `on_remove_user_third_party_identifier` module API callback would be a no-op. ([\#15227](https://github.com/matrix-org/synapse/issues/15227))
- Fix a rare bug introduced in Synapse 1.73 where events could remain unsent to other homeservers after a faster-join to a room. ([\#15248](https://github.com/matrix-org/synapse/issues/15248))
Internal Changes
----------------
- Refactor `filter_events_for_server`. ([\#15240](https://github.com/matrix-org/synapse/issues/15240))

Deprecations and Removals
-------------------------
- Deprecate the `on_threepid_bind` module callback, to be replaced by [`on_add_user_third_party_identifier`](https://matrix-org.github.io/synapse/v1.79/modules/third_party_rules_callbacks.html#on_add_user_third_party_identifier).

- Remove the unspecced `room_alias` field from the [`/createRoom`](https://spec.matrix.org/v1.6/client-server-api/#post_matrixclientv3createroom) response. ([\#15093](https://github.com/matrix-org/synapse/issues/15093))
- Remove the unspecced `PUT` on the `/knock/{roomIdOrAlias}` endpoint. ([\#15189](https://github.com/matrix-org/synapse/issues/15189))
- Remove the undocumented and unspecced `type` parameter to the `/thumbnail` endpoint. ([\#15137](https://github.com/matrix-org/synapse/issues/15137))
