Changelog

Developer-focused entries for API and portal changes. Marketing updates remain on /changelog.

Change policy

Backwards-compatible additions may ship inside /api/v1. Documented breaking changes get at least 90 calendar days of notice before removal, and Betspread-chosen coverage removals get 30 days of notice.

Release entries use change-class tags: [breaking], [backwards-compatible], [deprecation], [coverage-change], and [security]. Marketing rollups live on /changelog.

    Developer Portal v1

    Multi-route Developer Portal with dedicated quickstart, authentication, REST endpoint, Live WebSocket, generated API reference, errors, rate-limits, freshness, OpenAPI, and changelog pages. Code samples in cURL, Node.js, and Python. Fixed mobile docs navigation, duplicate H1, header CTA double-render, and cross-origin RSC prefetch CORS noise on /docs.

    Beta API expanded coverage

    Added grouped event odds at /api/v1/events/{eventId}/odds across 14 product-verified bookmakers for football. REST defaults remain stable; live channel stays opt-in per plan.
