  with a timestamped entry per release; the measurement platform ships dated monthly
  emissions-model releases plus semver API versions.

    the most recent at 18:53 UTC.
  entry_structure:
    note: >-
      Entries are unusually disciplined for a public changelog — each change states its Action
      (what existing customers must do), Buyer impact, Monetization (whether a new fee or meter
      is introduced), and Rollout and controls (entitlement gating, kill switch, adoption
      criteria before expansion).
    fields: [Action, Buyer impact, Monetization, Rollout and controls]
  entries:
  - version: 5.148.0
    date: '2026-08-13T18:53:00Z'
    type: additions
    breaking: false
    highlights:
    - Buyer signup intake now captures whether a prospect needs a campaign management system or an AI agent, plus markets, channels and timing.
    - Universal Ads connection capabilities now report CRM audience sync as unsupported, and sync attempts stop before changing provider data.
    - Sellers with the modular-sources entitlement can send inventory feeds through authenticated Storefront API endpoints (preview, commit, push).
    - Media buys reject an ISO subdivision before dispatch when a seller capability marks that value unsupported.
    action: No action required for existing sellers; existing sources, feed defaults and buyer-facing fulfillment are unchanged.
    monetization: No new fee, buyer charge, billing meter, or UI package; access follows the existing Enterprise modular-sources entitlement.
