+Synapse 1.27.0 (2021-02-16)
+===========================
+
+Note that this release includes a change in Synapse to use Redis as a cache ─ as well as a pub/sub mechanism ─ if Redis support is enabled for workers. No action is needed by server administrators, and we do not expect resource usage of the Redis instance to change dramatically.
+
+This release also changes the callback URI for OpenID Connect (OIDC) identity providers. If your server is configured to use single sign-on via an OIDC/OAuth2 IdP, you may need to make configuration changes. Please review [UPGRADE.rst](UPGRADE.rst) for more details on these changes.
+
+This release also changes escaping of variables in the HTML templates for SSO or email notifications. If you have customised these templates, please review [UPGRADE.rst](UPGRADE.rst) for more details on these changes.
