-### Added
+### Features
 
-  - **Basic OAuth2.0** 🎉
-    - You can now authenticate via apps like Roundcube using OAuth2.0 (LDAP/FILE provider still required)
+  - **Authentication with OIDC / OAuth 2.0** 🎉
+    - DMS now supports authentication via OAuth2 (_`XOAUTH` or `OAUTHBEARER`_) from capable services (_like Roundcube_).
+    - This does not replace the need for an `ACCOUNT_PROVISIONER` (`FILE` / `LDAP`). Authentication (Dovecot PassDB) still requires an existing account (Dovecot UserDB) to be successful,.
