note: >-
  Criteo maintains a separate changelog per product. Entries are labelled by VERSION rather
  than by date — the label is the release train (e.g. "2026.07 Version") and the date is
  implied by the release schedule in lifecycle/criteo-lifecycle.yml. Only the experimental
  entries carry a calendar label. Each entry is tagged, and "Breaking Change" is an explicit
  tag, which makes the breaking-vs-additive split machine-legible. Recent window captured
  below; the live changelogs remain the source of truth.

scheme:
  versioning: date-based stable versions (YYYY-MM), two per year
  entry_label: version train name, or month for experimental releases
  tags: [New releases, Breaking Change, Experimental]
  breaking_changes_flagged: true
  dated_entries: partial
  rss: null
  rss_note: No RSS/Atom feed is published for either changelog.

      Line Item Core — a new set of type-agnostic line item endpoints in Experimental. One
      contract for every campaign type: pass a campaignId and the API infers the line item
      type, with type-specific settings carried in a details object (initial support:
      Onsite Display Auction via onsiteDisplayDetails).
