To avoid potential security implications, setting the host in manifest probes will be disabled in Q3 2026 for CD versions and in the 2027 annual release. Uploading a microservice that uses the `host` parameter within the readiness or liveness probe will be rejected. For testing purposes, the new behavior can already be enabled via a feature toggle `core.ms-hosting.no-host-in-probes-in-manifest`. > **Important** > In Q3 2026 for the CD versions and in 2027 for the yearly releases, the new behavior will become **mandatory**. ~
