  CallRail maintains a dated API changelog inside the v3 reference itself. Entries are prose, dated
  by day, and describe field additions, endpoint enhancements, webhook payload changes and policy
  changes. There are no version numbers per entry — the API version has been v3 throughout — and no
  RSS/Atom feed or separate changelog host.
