+Synapse 1.73.0rc2 (2022-12-01)
+==============================
+
+Please note that legacy Prometheus metric names have been removed in this release; see [the upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.73/docs/upgrade.md#legacy-prometheus-metric-names-have-now-been-removed) for more details.
+
+Bugfixes
+--------
+
+- Fix a regression in Synapse 1.73.0rc1 where Synapse's main process would stop responding to HTTP requests when a user with a large number of devices logs in. ([\#14582](https://github.com/matrix-org/synapse/issues/14582))
+
+
+Synapse 1.73.0rc1 (2022-11-29)
+==============================
+
+Features
+--------
+
+- Speed-up `/messages` with `filter_events_for_client` optimizations. ([\#14527](https://github.com/matrix-org/synapse/issues/14527))
+- Improve DB performance by reducing amount of data that gets read in `device_lists_changes_in_room`. ([\#14534](https://github.com/matrix-org/synapse/issues/14534))
+- Adds support for handling avatar in SSO login. Contributed by @ashfame. ([\#13917](https://github.com/matrix-org/synapse/issues/13917))
+- Move MSC3030 `/timestamp_to_event` endpoints to stable `v1` location (`/_matrix/client/v1/rooms/<roomID>/timestamp_to_event?ts=<timestamp>&dir=<direction>`, `/_matrix/federation/v1/timestamp_to_event/<roomID>?ts=<timestamp>&dir=<direction>`). ([\#14471](https://github.com/matrix-org/synapse/issues/14471))
+- Reduce database load of [Client-Server endpoints](https://spec.matrix.org/v1.5/client-server-api/#aggregations) which return bundled aggregations. ([\#14491](https://github.com/matrix-org/synapse/issues/14491), [\#14508](https://github.com/matrix-org/synapse/issues/14508), [\#14510](https://github.com/matrix-org/synapse/issues/14510))
+- Add unstable support for an Extensible Events room version (`org.matrix.msc1767.10`) via [MSC1767](https://github.com/matrix-org/matrix-spec-proposals/pull/1767), [MSC3931](https://github.com/matrix-org/matrix-spec-proposals/pull/3931), [MSC3932](https://github.com/matrix-org/matrix-spec-proposals/pull/3932), and [MSC3933](https://github.com/matrix-org/matrix-spec-proposals/pull/3933). ([\#14520](https://github.com/matrix-org/synapse/issues/14520), [\#14521](https://github.com/matrix-org/synapse/issues/14521), [\#14524](https://github.com/matrix-org/synapse/issues/14524))
+- Prune user's old devices on login if they have too many. ([\#14038](https://github.com/matrix-org/synapse/issues/14038), [\#14580](https://github.com/matrix-org/synapse/issues/14580))
+
+
+Bugfixes
+--------
+
+- Fix a long-standing bug where paginating from the start of a room did not work. Contributed by @gnunicorn. ([\#14149](https://github.com/matrix-org/synapse/issues/14149))
+- Fix a bug introduced in Synapse 1.58.0 where a user with presence state `org.matrix.msc3026.busy` would mistakenly be set to `online` when calling `/sync` or `/events` on a worker process. ([\#14393](https://github.com/matrix-org/synapse/issues/14393))
+- Fix a bug introduced in Synapse 1.70.0 where a receipt's thread ID was not sent over federation. ([\#14466](https://github.com/matrix-org/synapse/issues/14466))
+- Fix a long-standing bug where the [List media admin API](https://matrix-org.github.io/synapse/latest/admin_api/media_admin_api.html#list-all-media-in-a-room) would fail when processing an image with broken thumbnail information. ([\#14537](https://github.com/matrix-org/synapse/issues/14537))
+- Fix a bug introduced in Synapse 1.67.0 where two logging context warnings would be logged on startup. ([\#14574](https://github.com/matrix-org/synapse/issues/14574))
+- In application service transactions that include the experimental `org.matrix.msc3202.device_one_time_key_counts` key, include a duplicate key of `org.matrix.msc3202.device_one_time_keys_count` to match the name proposed by [MSC3202](https://github.com/matrix-org/matrix-spec-proposals/pull/3202). ([\#14565](https://github.com/matrix-org/synapse/issues/14565))
+- Fix a bug introduced in Synapse 0.9 where Synapse would fail to fetch server keys whose IDs contain a forward slash. ([\#14490](https://github.com/matrix-org/synapse/issues/14490))
+
+
+Improved Documentation
+----------------------
+
+- Fixed link to 'Synapse administration endpoints'. ([\#14499](https://github.com/matrix-org/synapse/issues/14499))
+
+
+Deprecations and Removals
+-------------------------
+
+- Remove legacy Prometheus metrics names. They were deprecated in Synapse v1.69.0 and disabled by default in Synapse v1.71.0. ([\#14538](https://github.com/matrix-org/synapse/issues/14538))
+
+
+Internal Changes
+----------------
+
+- Improve type hinting throughout Synapse. ([\#14055](https://github.com/matrix-org/synapse/issues/14055), [\#14412](https://github.com/matrix-org/synapse/issues/14412), [\#14529](https://github.com/matrix-org/synapse/issues/14529), [\#14452](https://github.com/matrix-org/synapse/issues/14452)).
+- Remove old stream ID tracking code. Contributed by Nick @Beeper (@fizzadar). ([\#14376](https://github.com/matrix-org/synapse/issues/14376), [\#14468](https://github.com/matrix-org/synapse/issues/14468))
+- Remove the `worker_main_http_uri` configuration setting. This is now handled via internal replication. ([\#14400](https://github.com/matrix-org/synapse/issues/14400), [\#14476](https://github.com/matrix-org/synapse/issues/14476))
+- Refactor `federation_sender` and `pusher` configuration loading. ([\#14496](https://github.com/matrix-org/synapse/issues/14496))
+([\#14509](https://github.com/matrix-org/synapse/issues/14509), [\#14573](https://github.com/matrix-org/synapse/issues/14573))
+- Faster joins: do not wait for full state when creating events to send. ([\#14403](https://github.com/matrix-org/synapse/issues/14403))
+- Faster joins: filter out non local events when a room doesn't have its full state. ([\#14404](https://github.com/matrix-org/synapse/issues/14404))
+- Faster joins: send events to initial list of servers if we don't have the full state yet. ([\#14408](https://github.com/matrix-org/synapse/issues/14408))
+- Faster joins: use servers list approximation received during `send_join` (potentially updated with received membership events) in `assert_host_in_room`. ([\#14515](https://github.com/matrix-org/synapse/issues/14515))
+- Fix type logic in TCP replication code that prevented correctly ignoring blank commands. ([\#14449](https://github.com/matrix-org/synapse/issues/14449))
+- Remove option to skip locking of tables when performing emulated upserts, to avoid a class of bugs in future. ([\#14469](https://github.com/matrix-org/synapse/issues/14469))
+- `scripts-dev/federation_client`: Fix routing on servers with `.well-known` files. ([\#14479](https://github.com/matrix-org/synapse/issues/14479))
+- Reduce default third party invite rate limit to 216 invites per day. ([\#14487](https://github.com/matrix-org/synapse/issues/14487))
+- Refactor conversion of device list changes in room to outbound pokes to track unconverted rows using a `(stream ID, room ID)` position instead of updating the `converted_to_destinations` flag on every row. ([\#14516](https://github.com/matrix-org/synapse/issues/14516))
+- Add more prompts to the bug report form. ([\#14522](https://github.com/matrix-org/synapse/issues/14522))
+- Extend editorconfig rules on indent and line length to `.pyi` files. ([\#14526](https://github.com/matrix-org/synapse/issues/14526))
+- Run Rust CI when `Cargo.lock` changes. This is particularly useful for dependabot updates. ([\#14571](https://github.com/matrix-org/synapse/issues/14571))
+- Fix a possible variable shadow in `create_new_client_event`. ([\#14575](https://github.com/matrix-org/synapse/issues/14575))
+- Bump various dependencies in the `poetry.lock` file and in CI scripts. ([\#14557](https://github.com/matrix-org/synapse/issues/14557), [\#14559](https://github.com/matrix-org/synapse/issues/14559), [\#14560](https://github.com/matrix-org/synapse/issues/14560), [\#14500](https://github.com/matrix-org/synapse/issues/14500), [\#14501](https://github.com/matrix-org/synapse/issues/14501), [\#14502](https://github.com/matrix-org/synapse/issues/14502), [\#14503](https://github.com/matrix-org/synapse/issues/14503), [\#14504](https://github.com/matrix-org/synapse/issues/14504), [\#14505](https://github.com/matrix-org/synapse/issues/14505)).
