provider: Flagsmith
note: >-
  Flagsmith publishes first-party clients across thirteen ecosystems, every one of them from the
  github.com/Flagsmith organisation, so `official: true` is a repository-ownership fact rather than a
  judgement. Currency is uneven and the structured `published:` dates make it legible: the JS, PHP,
  Go, Python, Java, .NET, Rust and Elixir clients are current, while the Ruby gem (4.3.0,
  2024-12-06) and the standalone Kotlin (non-Android) client (5.0.2, 2022-08-09) have not shipped a
  release in over a year against an API whose own changelog moves every one to two weeks.

  version: 2.0.0
  published: '2026-08-21'
  note: >-
    npm is one distribution channel for the Go CLI binary (Homebrew, an install script and GitHub
    Releases are the others). The 2.0.0 line is the rewritten Go CLI; the pre-2.0 npm package was a
    different, now-legacy Node CLI. See cli/flagsmith-cli.yml.

  published: '2022-08-09'
  note: >-
    Last release 2022-08-09 — superseded in practice by flagsmith-kotlin-android-client. Recorded
    because it is still resolvable from Maven Central; treat the Android client as the live one.

    Major-version module path. The /v3 path still resolves (v3.7.0, 2024-09-30) and the /v4 path
    resolves to v4.4.0 (2025-06-26); v5 is current.

  repository: https://github.com/Flagsmith/flagsmith-ruby-client
  language: Ruby
  official: true
  version: 4.3.0
  published: '2024-12-06'
  note: >-
    Oldest current release of any first-party Flagsmith client — no gem push since 2024-12-06, though
    the repository itself was pushed to 2026-09-05. The gem, not the repo, is what a Ruby consumer
    gets.

  version: 2.3.1
  published: '2025-11-10'
  note: >-
    The Elixir client ships as the flagsmith_engine package. A second Hex package,
    flagsmith_elixir_sdk (0.1.2, 2021-11-01), is an abandoned earlier attempt.

  version: 3.9.0
  published: '2025-10-31'
  note: >-
    CocoaPods trunk lags the repository: GitHub Releases carries v3.10.0 (2026-04-15), which is
    distributed through Swift Package Manager. SPM has no version metadata endpoint, so the SPM
    consumer's version is the git tag v3.10.0 (2026-04-15).

  published: '2026-04-15'
  note: >-
    OpenFeature Java provider for Flagsmith. Published by the OpenFeature project, not by Flagsmith —
    recorded as related rather than official. Flagsmith DOES publish its own OpenFeature providers
    for Swift, Kotlin and Python from its own org (flagsmith-openfeature-swift-provider,
    flagsmith-openfeature-provider-kotlin, flagsmith-openfeature-provider-python); those ship from
    GitHub/SPM rather than a versioned registry we could read a date from.

  registry: packagist
  url: https://packagist.org/packages/clearlyip/laravel-flagsmith
  language: PHP
  official: false
  version: null
  note: >-
    Third-party Laravel wrapper (401k downloads). Version deliberately not recorded — it is not a
    Flagsmith release and its currency says nothing about the provider.
