  The changelog covers the Deltakit SDK (the meta-package and its component packages), not the
  Deltakit Cloud API. Riverlane publishes no separate API changelog — a cloud-side change is only
  visible when it lands in a client release. Recent window only; the live changelog is the source
  of truth.

  Entries for 0.5.0 through 0.8.0 are recorded as version + date only; per-release highlights were
  not transcribed. Breaking-change flags are null rather than false where not verified — the
  package is pre-1.0 and declared alpha, so breaking changes between minors are permitted.
- No changelog exists for the cloud API surface itself.
