+| 3.27.1 | DFP Video Module bug fixed |
+| 3.27 | An important bug in the DFP Video Module was introduced with this release and fixed in 4.3 and 3.27.1. The dfpVideoModule only looked in adunit.sizes but adunit.sizes was stripped. Unfortunately there's not a workaround - if you use that video module, you shouldn't use Prebid.js 3.27 through 4.2 inclusive. |
 | 3.24 | PBS Bid Adapter allows setting site params |
 | 3.23 | If a server-side bid contains imp.ext.prebid.event.win, pbsBidAdapter listens to BidsWon events and hits the URL. |
 | 3.22 | Secure creatives use event.origin rather than a hard coded adServerDomain |
