  Acall publishes a dated release-notes feed for the WorkstyleOS product covering 24 pages of history. There
  is no API-specific changelog: the Public API is not versioned in these notes and no entry in the recent
  window describes a change to the v1 REST contract. Entries below are the recent window read from the feed
  on 2026-09-06; the live feed is the source of truth.
