+Synapse 1.33.2 (2021-05-11)
+===========================
+
+Due to the security issue highlighted below, server administrators are encouraged to update Synapse. We are not aware of these vulnerabilities being exploited in the wild.
+
+Security advisory
+-----------------
+
+This release fixes a denial of service attack ([CVE-2021-29471](https://github.com/matrix-org/synapse/security/advisories/GHSA-x345-32rc-8h85)) against Synapse's push rules implementation. Server admins are encouraged to upgrade.
+
+Internal Changes
+----------------
+
+- Unpin attrs dependency. ([\#9946](https://github.com/matrix-org/synapse/issues/9946))
+
+
+Synapse 1.33.1 (2021-05-06)
+===========================
+
+Bugfixes
+--------
+
+- Fix bug where `/sync` would break if using the latest version of `attrs` dependency, by pinning to a previous version. ([\#9937](https://github.com/matrix-org/synapse/issues/9937))
+
+
 Synapse 1.33.0 (2021-05-05)

+====================
+
+`room_invite_state_types` configuration setting
+-----------------------------------------------
+
+The ``room_invite_state_types`` configuration setting has been deprecated and
+replaced with ``room_prejoin_state``. See the `sample configuration file <https://github.com/matrix-org/synapse/blob/v1.34.0/docs/sample_config.yaml#L1515>`_.
+
+If you have set ``room_invite_state_types`` to the default value you should simply
+remove it from your configuration file. The default value used to be:
+
+.. code:: yaml
+
+   room_invite_state_types:
+      - "m.room.join_rules"
+      - "m.room.canonical_alias"
+      - "m.room.avatar"
+      - "m.room.encryption"
+      - "m.room.name"
+
+If you have customised this value by adding addition state types, you should
+remove ``room_invite_state_types`` and configure ``additional_event_types`` with
+your customisations.
+
+If you have customised this value by removing state types, you should rename
+``room_invite_state_types`` to ``additional_event_types``, and set
+``disable_default_event_types`` to ``true``.
