OpenRTB 2.1

Released 2012-103 cataloged changes

What this release is

OpenRTB 2.1 was a consolidation release: it clarified how VAST video rides in RTB transactions (including impressions that can sell as either banner or video), added IAB Tier-2 content categories, and introduced location-source provenance so a buyer can tell GPS-derived coordinates from ZIP-derived ones.

Validate against 2.1

The tester can pin validation to this exact revision, so deprecated, moved, and not-yet-available findings reflect what 2.1 actually says. The same pin works in the CLI: rtblint validate --version 2.1 request.json.
