name: Linera Protocol Lifecycle
description: >-
  Versioning and release-lifecycle posture for the Linera protocol and its
  client libraries. Linera is pre-1.0 open-source infrastructure released under
  a rolling 0.15.x line; the developer experience is anchored to an evolving
  public Testnet rather than a long-term-support production API.
versioning:
  scheme: semver
  current_version: 0.15.19
  channel: pre-1.0 (0.x); breaking changes may land between minor releases
  release_source: https://github.com/linera-io/linera-protocol/releases
environments:
  - name: Testnet
    purpose: >-
      Public test network developers claim microchains on (via the faucet) and
      deploy applications to; the primary target for the current release line.
  - name: local
    purpose: Local validator network spun up with the linera CLI for development.
deprecation:
  policy_published: false
  headers:
    sunset: false
    deprecation: false
  notes: >-
    No formal RFC 8594 Sunset/Deprecation header policy is published; because
    the protocol is pre-1.0 and Testnet-anchored, compatibility tracks the
    active release line rather than a documented deprecation window. Yanked
    linera-alloy* crates on crates.io are the observable deprecation signal.
status_page:
  published: false
  notes: No dedicated public status page identified for the Testnet at time of enrichment.
