Changelog

Every change to the v3 API contract ships as a new version of the published API description. The number here is the same one you see as version in the v3 reference.

Entries are additive. Breaking changes ship as a new major version — see Versioning.

The legacy REST API is frozen, receives no entries, and stops serving requests on 1 September 2027.
