Prebid.js 11.4.0 Released
Prebid.js published release 11.4.0 containing new features, bug fixes and maintenance updates for the open-source header-bidding library. Key additions include VAST tracker event-injection support, build-option support for non-Webpack bundlers, a new minTargetedBidCacheTTL setting to prevent winning bids from expiring, and a new LOGLY bidder adapter. The release also fixes a PBS Adapter bug that prevented sending an empty bidder array in eidpermissions and includes multiple adapter-specific maintenance changes (consent handling fixes, endpoint corrections, floor price support), dependency bumps, and new/updated adapters such as adsmovil and PubstackAdapter improvements.
Prebid.js is a widely used open-source header-bidding library; this incremental technical release adds adapters, bug fixes and build/consent improvements that affect publisher and integration stability but does not represent a major industry shift.
