description: >-
  SendGrid's product changes are published through the unified Twilio changelog,
  filtered to the sendgrid-email-api and twilio-sendgrid-platform products. This
  artifact records the versioning/change-communication scheme and points to the
  live, dated changelog as the source of truth. Individual dated SendGrid
  entries were NOT transcribed here because the filtered changelog is rendered
  client-side and the recent window is dominated by cross-product Twilio
  platform items; capturing specific SendGrid entries verbatim would risk
  misattribution. The live URL below is the authoritative recent window.

    Twilio changelog with an effective date, rather than by minting a new pinned
    API version. Filter facets include product (SendGrid Email API, Twilio
    SendGrid Platform) and change type.
