+Synapse 1.56.0 (2022-04-05)
+===========================
+
+Synapse will now refuse to start up if open registration is enabled, in order to help mitigate
+abuse across the federation. If you would like
+to provide registration to anyone, consider adding [email](https://github.com/matrix-org/synapse/blob/8a519f8abc6de772167c2cca101d22ee2052fafc/docs/sample_config.yaml#L1285),
+[recaptcha](https://matrix-org.github.io/synapse/v1.56/CAPTCHA_SETUP.html)
+or [token-based](https://matrix-org.github.io/synapse/v1.56/usage/administration/admin_api/registration_tokens.html) verification
+in order to prevent automated registration from bad actors.
+This check can be disabled by setting the `enable_registration_without_verification` option in your
+homeserver configuration file to `true`. More details are available in the
+[upgrade notes](https://matrix-org.github.io/synapse/v1.56/upgrade.html#open-registration-without-verification-is-now-disabled-by-default).
+
+Synapse will additionally now refuse to start when using PostgreSQL with a non-`C` values for `COLLATE` and `CTYPE`, unless
+the config flag `allow_unsafe_locale`, found in the database section of the configuration file, is set to `true`. See the
+[upgrade notes](https://matrix-org.github.io/synapse/v1.56/upgrade#change-in-behaviour-for-postgresql-databases-with-unsafe-locale)
+for details.
