    PowerMill ships as a named yearly product release (2024, 2025, 2026, 2027) with in-year point
    updates numbered <year>.<minor>.<patch> (e.g. 2026.0.1). Documentation is versioned by the same
    year key on help.autodesk.com. There is no HTTP API and therefore no URI/header API versioning.

  note: >-
    Autodesk publishes an available-product-versions policy that governs which prior releases remain
    installable, and its security programme treats unsupported/unpatched desktop versions as
    explicitly out of scope. That is a real, published version-support boundary, but it is a PRODUCT
    lifecycle policy, not an API deprecation policy — no operation-level deprecation notice, no
    Sunset/Deprecation headers, no per-interface removal schedule is published.

    PowerMill itself is desktop software and has no component on the dashboard. The component it
    depends on is "Identity, Licensing & Entitlement", which gates PowerMill sign-in and licensing;
    "Autodesk account" and "Autodesk App Store" are also listed. Recorded as an Autodesk-wide status
    surface, not a PowerMill service status.
sla:
  published: false
  note: No API SLA is published; PowerMill is licensed seat software, not a hosted service.
deprecated_operations: []
api_surface_note: >-
  There is no machine-readable API contract to derive deprecated operations from. PowerMill's
  programmable surfaces are (1) macro commands executed inside a PowerMill session and (2) the
  Autodesk.ProductInterface.PowerMILL .NET/COM automation library, whose lifecycle is tracked on
  NuGet — see packages/autodesk-powermill-packages.yml, where the newest STABLE build is 1.2.5
  (2024-04-05) while the head is 1.3.9-alpha (2026-02-01).
