scheme:
  style: numbered platform releases with a build number
  format: '<major>.<minor> (<build>)'
  example: 6.2 (2603)
  cadence: roughly every one to three months
  note: >-
    CoreStack runs TWO parallel changelogs and the distinction matters. "Release Notes <version>"
    covers the product and the console. "External APIs <version>" is a separate, per-release document
    written for API consumers, and it is unusually specific: every added, changed, decommissioned and
    deprecated operation is listed by METHOD + PATH + summary, and every changed operation itemises
    the individual request parameters and response fields added or removed. That is a materially
    better API changelog than most enterprise platforms publish, and it is the strongest single
    artifact in CoreStack's developer surface.

  section: What's Coming in the Next Release?
  note: >-
    Each External APIs release note ends with the NEXT build's planned additions and changes, named
    to the operation and to the individual field. 6.2 (2603) names three new service-account
    operations and twenty changing operations planned for 2604. This is a published API roadmap in
    all but name, and it gives an integrator advance notice at field granularity.

  documented: true
  example_release: '4.3 (2401)'
  url: https://docs.corestack.io/docs/whats-deprecated
  note: >-
    The 4.3 (2401) release published a dedicated "What's Deprecated" page listing roughly thirty
    operations struck through by method and path — alert configuration, compliance control mapping,
    cost savings account/tenant summaries, the entire /governance/account cloud-account family, and
    the /operations/anomaly_detector family. Later releases fold the equivalent information into a
    "What's Decommissioned" section of the External APIs note; 6.1 and 6.2 both record "None".
