Its GraphQL reference is generated from the schema we currently serve, so it always shows what is deployed today but not what changed or why. This changelog is where you find that. It starts here, so it does not cover changes made before this entry. From now on, every change to the published schema is recorded on this page: * **Additions** are collected into one entry per month, covering new queries, mutations, fields, optional arguments, and enum values. Your existing queries keep working, so you can review a month of additions together. * **Changes to what already exists** get their own dated entry, covering renames, removals, deprecations, arguments that become required, and changes to permissions, pagination, or error codes. While the Headless API is in beta, a change can ship without a deprecation period, so check this page before you upgrade an integration.
