  format: name-X.Y.Z-build-milestone
  current: 7.2.1-1r1
  api_versioning: uri-path
  api_current: v1
  api_note: >-
    The REST surface is versioned in the URI path (/api/v1). It has carried the v1 prefix across
    every release stream documented, and no v2 or deprecation timeline for it is published.
  docs: https://docs.128technology.com/docs/about_releases
release_model:
  cadence: A new release stream every 6 months.
  milestones:
  - id: r1
    name: Release Candidate 1
    description: Initial feature release; first version of every major.minor stream.
  - id: r2
    name: Release Candidate 2
    description: Additional features, released 3 months after R1.
  - id: sts
    name: Standard Term Support
    description: Supported for 9 months from the STS designation date.
  - id: lts
    name: Long Term Support
    description: Supported for 24 months from the LTS designation date.
  designation_note: >-
    STS or LTS is assigned 3 months after R2 and the designations alternate between streams.
    Support timelines start from the designation date, not the initial release date.
  patch_policy: >-
    Patch releases may occur between R1 and R2. Once R2 ships, customers should move to R2 to
    keep receiving fixes on that stream. Issues resolved in a release merge forward both
    chronologically and lexicographically.

  sunset_header: false
  sunset_header_note: >-
    No RFC 8594 Sunset or Deprecation response header is documented for the REST API. Lifecycle
    is announced as product EOL milestones on the Juniper Session Smart Router Dates & Milestones
    page, not in the HTTP response.

sla:
  url: null
  uptime_target: null
  note: >-
    No SLA or uptime target applies. The SSR and Conductor are software the customer deploys and
    operates; there is no vendor-hosted API service to carry an availability commitment.
status_page: null
status_page_note: >-
  No status page exists and none would be meaningful — the API is served by the customer's own
  router or conductor, not by a vendor endpoint. No StatusPage pointer is emitted.

  environment_modification_note: >-
    SSR support agreements do not cover changes customers make to the underlying enterprise
    Linux environment; such changes are not guaranteed to survive a software upgrade.
deprecated_operations: []
deprecated_operations_note: >-
  Cannot be derived — no OpenAPI is published for the /api/v1 surface, so no operation-level
  deprecated flags are available.
