description: >-
  Carnival Mobile ships an on-device SDK rather than a versioned HTTP API, so its lifecycle contract is
  SDK release versioning plus a published rebrand migration path. Each platform SDK is independently
  versioned with semver and released through GitHub Releases. The product has been renamed twice
  (Carnival -> Sailthru Mobile -> Marigold), and each rename produced a new package name alongside a
  published migration guide, which is the provider's de facto deprecation contract.
versioning:
  scheme: semver-per-platform
  note: >-
    Each platform SDK carries its own major version line; they are not aligned with each other
    (iOS 19.x, Android 27.x, React Native 18.x as of 2026-05).
  current:
    ios: 19.0.0
    android: 27.0.2
    react_native: 18.0.1
  releases:
    ios: https://github.com/sailthru/sailthru-mobile-ios-sdk/releases
    android: https://github.com/sailthru/sailthru-mobile-android-sdk/releases

  sunset_header: false
  note: >-
    No RFC 8594 Sunset/Deprecation header contract — this is an SDK, not an HTTP API. The published
    deprecation surface is the Marigold Rebrand Migration Guide, which documents moving off the
    Carnival- and Sailthru Mobile-named packages onto the Marigold-named ones. A companion page,
    "Sailthru Specific Functionality", documents what remains available on the legacy EngageBySailthru
    class.
