notes:
- No entry is marked breaking; the introduction page commits breaking changes to a feature flag plus prior changelog notice, and webhook schema changes to an api_version bump.
- The page's newest entry (2026-08-15) predates the hosted rail's 12-lane expansion and the Arc lane go-live (16 September 2026) that the llms.txt and homepage describe, so the changelog lags the live surface by roughly a month.
