HubSpot has added a new changelog entry announcing that Pipeline and pipeline stage delete endpoints will enforce reference validation by default starting with the 2026-09 API version (live September 8, 2026). This is a breaking behavioral change for integrations that delete pipelines or pipeline stages which have existing references.

Migration: Review any integration code that calls Pipeline or pipeline stage delete endpoints. Ensure referenced objects (e.g., deals in a pipeline stage) are migrated or removed before deletion, or handle the new validation errors returned by the 2026-09 API version.
