AdCP 3.3: account change feed changed_paths and idempotency_key echo, creative seller_revision #1647
Description
Spec
For sellers declaring the experimental account.change_feed: records whose origin.kind is adcp or seller_operator MUST carry a non-empty changed_paths ("" for whole-resource create, delete or purge). Optionally, adcp records echo the originating request's idempotency_key, only on records served to the principal that sent the request. Other readers and notifications never carry it. Creatives may carry seller_revision, which account.change.resource_revision mirrors.
What's new §Account change feed; migration guide §Account change feed records and §Creative seller_revision (tag v3.3.0-beta.0).
