Prebid.js 11.26.0 Release
Two Prebid.js releases were published in quick succession: v11.26.0 on 2026-07-28 and v11.28.0 on 2026-08-04. v11.26.0 introduced core changes including realTimeData post-install support, removal of Topics API handling and an fpd validation library, plus a new SMB adapter, a DAA AdChoices Signal module, gamAdServerVideo GPP consent support, and multiple adapter maintenance updates. v11.28.0 added a core PR exposing COPPA to bidder user syncs, dependency bumps and build/CI fixes, and several adapter-specific changes: Yieldmo now blocks bids/syncs on COPPA requests, adQuery passes qid to user sync URLs, Pstudio moved user retrieval to localStorage, and AdSmartx was rebranded to Agenticx with audio ad support. Releases were published via GitHub Actions and source archives were timestamped; 11.28 uses tag ea49e63.
Prebid.js is a widely used open-source header bidding library; this release adds a new adapter and modules and contains core and adapter updates that affect publishers and integrators, but it is an incremental technical release rather than an industry-wide shift.
