  Clinical Knowledge Manager (the application). The CKM REST API's own contract version (1.6.0) is
  not separately changelogged; API changes ride the application release.
current_version: 1.21.0
note: >-
  The canonical, dated release index is hosted on the openEHR Confluence (space "healthmod",
  maintained by Ocean's CKM lead Sebastian Garde) rather than on oceanhealthsystems.com. It lists
  every CKM release from 1.0.2 through 1.21.0 with per-release notes pages, and was last updated
  23-Feb-2026. The index itself does not print per-release dates; the dates below are the
  publication dates of Ocean's own announcement posts, taken from the site sitemap, and are marked
  announced: true to distinguish them from a vendor-stated release date.
