Prebid 10 and 11: what changed in your wrapper

Mistake. Upgrading Prebid by changing the version number, and nothing else.

A breaking change is an update that makes old settings stop working.

Prebid.js ten shipped in July twenty twenty-five. Eleven followed in March twenty twenty-six, and removed sixteen modules. Say news.example still runs Prebid nine. Five checks before jumping to eleven. One, video. The DFP video module became the Google Ad Manager video module in ten, and the old name is gone in eleven. Two, your supply chain object, or schain, now goes in first-party data config. Three, ad pods for long video breaks are no longer supported. Four, with the storage control module on, any storage a module hasn’t disclosed now fails. Five, transaction IDs stay off unless you enable them, and since ten point nine each bidder gets its own. A newer setting can share one ID again.

Today, ask which Prebid version your wrapper runs, then check those five items in the release notes.

Next, how Prebid.js runs an auction, step by step.
