name: Topl / Apparatus API lifecycle
description: >-
  Lifecycle record for the Topl blockchain platform, rebranded Apparatus. The published
  contract and the published packages survive; the running service and every documentation
  host do not.
status: wound-down
versioning:
  scheme: semver with pre-release qualifiers
  lines:
  - {line: '1.x (Topl)', latest: 1.10.2, released: '2022-03-14', interface: JSON-RPC over HTTP, note: 'The Bifrost "Topl RPC" era.'}
  - {line: '2.x (Apparatus)', latest: 2.0.0-beta8, released: '2024-07-15', interface: gRPC + protobuf, note: 'Never reached a stable 2.0.0 release. Mainnet was never launched.'}
  current_version: 2.0.0-beta8
  breaking_change_policy: not published
deprecation:
  policy_published: false
  sunset_header: not observed
  note: >-
    No deprecation or sunset policy was ever published, and none was issued for the shutdown.
    The 1.x JSON-RPC surface was superseded by the 2.x gRPC surface without a documented
    migration or sunset window; the 2.x surface then went dark without an announcement that
    could be found on any reachable host.
