versioning:
  scheme: firmware-and-document
  api_version_field: none
  note: >-
    The wire protocol carries no version field. Behaviour is gated on device
    firmware version, and the developer manual is separately revision-controlled
    per product with an ANELLO document number.

deprecation:
  policy_url: null
  sunset_header: false
  note: >-
    No API deprecation policy, sunset window or removal schedule is published.
    The only documented deprecations are product renames and a tooling move,
    recorded below; they are naming changes, not interface removals, so no
    `Deprecation` pointer is emitted.
  renames:
  - {from: ANELLO GNSS INS, to: ANELLO GROUND INS, dated: '2026-01-16'}
  - {from: ANELLO GNSS INS/ATAK KIT, to: ANELLO GROUND INS/ATAK KIT, dated: '2026-01-16'}
  - {from: ANELLO IMU+, to: ANELLO GROUND IMU, dated: '2026-01-16'}
  tooling_moves:
  - change: >-
      ntrip_client moved out of ~/catkin_ws/src into the anello_ros_driver
      package src/script directories; upgrading from ROS driver <= v1.2.2
      requires deleting the old checkout and rebuilding.
