Partner API Release Notes

This page lists public-facing changes to the Partner API — response-schema additions, query-parameter changes, and behavior changes tied to documented fields. Backend-only improvements (performance, infrastructure, security hardening) and permission-gated features that are not documented on the public page are not listed.

Changes scoped to the sibling APIs are tracked separately: Availability, Top Picks, Inventory Status, and Discovery Feed.
