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.

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.
