+Synapse 1.80.0rc2 (2023-03-22)
+==============================
+
+Bugfixes
+--------
+
+- Fix a bug in which the [`POST /_matrix/client/v3/rooms/{roomId}/report/{eventId}`](https://spec.matrix.org/v1.6/client-server-api/#post_matrixclientv3roomsroomidreporteventid) endpoint would return the wrong error if the user did not have permission to view the event. This aligns Synapse's implementation with [MSC2249](https://github.com/matrix-org/matrix-spec-proposals/pull/2249). ([\#15298](https://github.com/matrix-org/synapse/issues/15298), [\#15300](https://github.com/matrix-org/synapse/issues/15300))
+- Fix a bug introduced in Synapse 1.75.0rc1 where the [SQLite port_db script](https://matrix-org.github.io/synapse/latest/postgres.html#porting-from-sqlite)
+  would fail to open the SQLite database. ([\#15301](https://github.com/matrix-org/synapse/issues/15301))
+
+
+Synapse 1.80.0rc1 (2023-03-21)
+==============================
+
+Features
+--------
+
+- Stabilise support for [MSC3966](https://github.com/matrix-org/matrix-spec-proposals/pull/3966): `event_property_contains` push condition. ([\#15187](https://github.com/matrix-org/synapse/issues/15187))
+- Implement [MSC2659](https://github.com/matrix-org/matrix-spec-proposals/pull/2659): application service ping endpoint. Contributed by Tulir @ Beeper. ([\#15249](https://github.com/matrix-org/synapse/issues/15249))
+- Allow loading `/register/available` endpoint on workers. ([\#15268](https://github.com/matrix-org/synapse/issues/15268))
+- Improve performance of creating and authenticating events. ([\#15195](https://github.com/matrix-org/synapse/issues/15195))
+- Add topic and name events to group of events that are batch persisted when creating a room. ([\#15229](https://github.com/matrix-org/synapse/issues/15229))
+
+
+Bugfixes
+--------
+
+- Fix a long-standing bug in which the user directory would assume any remote membership state events represent a profile change. ([\#14755](https://github.com/matrix-org/synapse/issues/14755), [\#14756](https://github.com/matrix-org/synapse/issues/14756))
+- Implement [MSC3873](https://github.com/matrix-org/matrix-spec-proposals/pull/3873) to fix a long-standing bug where properties with dots were handled ambiguously in push rules. ([\#15190](https://github.com/matrix-org/synapse/issues/15190))
+- Faster joins: Fix a bug introduced in Synapse 1.66 where spurious "Failed to find memberships ..." errors would be logged. ([\#15232](https://github.com/matrix-org/synapse/issues/15232))
+- Fix a long-standing error when sending message into deleted room. ([\#15235](https://github.com/matrix-org/synapse/issues/15235))
+
+
+Updates to the Docker image
+---------------------------
+
+- Ensure the Dockerfile builds on platforms that don't have a `cryptography` wheel. ([\#15239](https://github.com/matrix-org/synapse/issues/15239))
+- Mirror images to the GitHub Container Registry (`ghcr.io/matrix-org/synapse`). ([\#15281](https://github.com/matrix-org/synapse/issues/15281), [\#15282](https://github.com/matrix-org/synapse/issues/15282))
+
+
