description: >-
  Twilio's API versioning, support-lifecycle, deprecation, status, and SLA
  posture. Twilio runs a "classic" date-stamped API (/2010-04-01) plus
  per-product APIs versioned with a numeric /v1 or /v2 segment. Products move
  through a documented four-stage lifecycle (Latest -> Support -> Deprecated ->
  End of Life), and end-of-life is announced through dated changelog notices.
versioning:
  scheme: >-
    Classic API served under a fixed historical date path (/2010-04-01); each
    newer product API served from its own subdomain with a numeric version
    segment (/v1 or /v2).
  classic_path: /2010-04-01
  product_versions: [v1, v2]
