-Unreleased
-==========
+Synapse 1.27.0rc1 (2021-02-02)
+==============================
 
 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. 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 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.
