Removed features¶
The following capabilities available in previous MSR versions are not included in MSR 4:
SAML Support: MSR4 no longer supports SAML authentication and instead uses OpenID Connect (OIDC), a more modern and flexible standard that better aligns with cloud-native environments and improves security and scalability. Please refer to OIDC Authentication for more information on configuring OIDC.
Promotion Policies: Automated promotion policies are no longer included. Customers can adapt their CI/CD pipelines to achieve similar workflows.
Swarm support customers can use MSR4 as a single instance for Swarm environments instead of HA clusters
