Google Cloud Makes Compute Engine API Date-Based Versioning Generally Available

Google Cloud has made date-based versioning of the Compute Engine API generally available, replacing the single mutable /v1 surface with immutable quarterly snapshots such as 2026-09-01. Callers choose a version per request using a header or query parameter. New versions can change defaults, error formats, and IAM checks without affecting existing /v1 callers, a model Azure Resource Manager and Stripe have used for years.

Why it matters: Infrastructure and automation teams gain a predictable way to adopt Compute Engine API changes on their own schedule, but they will need to pin versions and test IAM and error-handling behavior when they upgrade.
