versioning:

  platform_scheme: major.minor
  platform_current: '27.1'
  docs: https://docs.ocient.com/version-compatibility
  release_notes: https://docs.ocient.com/release-notes
  note: The HTTP Query API path prefix has remained /v1; platform capability moves
    with the Ocient System release number, and clients are pinned to a system release
    by a published compatibility matrix.
compatibility_matrix:
  docs: https://docs.ocient.com/version-compatibility
  description: Published table pairing each Ocient System version with recommended
    JDBC driver versions and minimum Java versions.
  entries:
  - {system: '27.1', jdbc: 4.2.0, java: 8 or later}
  - {system: '27.0', jdbc: 4.1.0, java: 8 or later}
  - {system: '26.1', jdbc: 3.7.0 and 4.0.0, java: 8 or later}
  - {system: '25.5', jdbc: 3.6.7, 3.6.6, 3.6.5, and 3.6.4, java: 8 or later}
  - {system: '25.2', jdbc: 3.5.1, java: 8 or later}
  - {system: '25.1', jdbc: 3.4.1, java: 8 or later}
  - {system: '25.0', jdbc: 3.3.1, java: 8 or later}
  - {system: 24.3 and 24.4, jdbc: 3.2.x, java: 11 or later}
  - {system: 23.1, 24.0, 24.1, and 24.2, jdbc: 3.1.7, java: 8 or later}
  - {system: '23.0', jdbc: '3.0', java: 8 or later}
  jdbc_api_support: The docs also publish a JDBC API version conformance table
    (through JDBC 4.3) recording which requirements the Ocient driver supports.
deprecation:
  policy_url: null
  published_policy: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  mechanism: 'Behavioral changes are announced under a "Version Compatibility" heading
    inside each release note rather than through a standalone deprecation policy or
    HTTP Sunset/Deprecation headers.'
  examples:
  - {release: '27.1', change: The array_to_string SQL function no longer adds quotes
      around values of VARCHAR arrays.}
  note: 'Recorded honestly: Ocient publishes per-release breaking-change notices and
    a driver/system compatibility matrix, but no separate deprecation policy document
    and no RFC 8594 header support.'
upgrade:
  docs: https://docs.ocient.com/ocient-software-upgrade
  description: Documented Ocient software upgrade procedure for customer-deployed and
    managed systems.
sla:
  url: null
  uptime_target: null
  note: No public SLA or uptime target is published; service levels are set by the
    applicable service agreement for OcientCloud and Ocient Management Services.
status_page:
  url: null
  probed: ['https://status.ocient.com/ — no DNS resolution']
  note: Ocient publishes no public status page. The platform is deployed per customer
    (OcientCloud, customer-deployed, or hybrid) rather than as a shared multi-tenant
    service, so no `StatusPage` pointer is emitted.
