API Changelog

New endpoints, behaviour changes, fixes and deprecations. Breaking response changes will not be slipped into v1.

v1.0 — Initial Public API

Released 10 September 2026. Introduced current time, timezone, conversion, cities, city, countries, country, sun, moon, Unix timestamp, calendar and formatting endpoints, together with the API Explorer and same-origin exact-time synchronisation service.

Deprecated endpoints: none in v1.0. Breaking response-contract changes are reserved for a future versioned route.

Versioning policy: additive, backwards-compatible improvements may land in v1. A breaking response-contract change belongs under a future /api/v2/.
