Spec-to-deployment linkage and gateway revision tracking in API hub (GA)

Spec-to-deployment linkage and gateway revision tracking in API hub (GA)

API hub now provides a first-class, bidirectional link between API specifications, operations, and the deployments that serve them, together with native tracking of the underlying gateway revision.

What's new

• Direct visibility between specs and deployments: See exactly which API specification and operations are served by a specific deployment, and navigate from a spec to the deployments that serve it.
• Native gateway revision tracking: Deployments now capture and display their underlying gateway revision (for example, an Apigee proxy revision) via the new source_revision field on the Deployment resource.
• More accurate operation resolution: When multiple revisions expose overlapping operations (same method and path), API hub associates each operation with its specific specification instead of dropping duplicates.
• Multiple spec revisions per API: API hub can store multiple revisions of the same spec for an API deployed across different environments.
