  First-party SDKs published under the github.com/attendease organization.
  Versions and publish dates below were read from the registry metadata endpoints
  on 2026-08-13. CURRENCY IS THE FINDING: every published first-party client is
  stale relative to the API it wraps. The JavaScript SDK last shipped in January
  2017, the CMS Blocks package in March 2017, and the RubyGems "attendease" gem is
  a 0.0.0 placeholder from 2014 that was never developed. Only the Jekyll plugin
  has a release this decade (2023). The one actively maintained repository,
  attendease-sdk-ruby (pushed 2025-01-29), has never been published to RubyGems —
  its gemspec name "attendease_sdk" returns 404 there — so it is installable only
  from source. No PyPI, NuGet, Maven, Go, Packagist, or crates.io first-party
  package exists.

  note: >-
    Version 0.0.0, published 2014-12-05 and never updated — a reserved name /
    placeholder gem, not a working client. The real Ruby SDK lives unpublished at
    github.com/attendease/attendease-sdk-ruby.

  note: >-
    The most recently released first-party package (2023-10-19). Its declared
    source_code_uri, github.com/attendease/jekyll-attendease, now returns HTTP 404
    — the repository has been removed or made private, so the gem's source is no
    longer public.

  version: null
  published: null
  official: true
  note: >-
    version/published are null because this package is not distributed through any
    registry — checked, nothing to record. rubygems.org/api/v1/gems/attendease_sdk
    returns 404 and rubygems.org/api/v1/gems/attendease-sdk returns 404. The
    repository carries attendease_sdk.gemspec and was last pushed 2025-01-29,
    making it the only first-party client with recent activity, but consumers must
    install it from git.
