Prebid.js 11.16.0 Released
Prebid.js published version 11.16.0 on 2026-06-09 (release authored by github-actions). The release includes core PRs adding identity typings (publinkId, euid, uid2, pubProvided), new typings for the gamAdServerVideo module, and telemetry callbacks (onTimeout/onBidderError) for the Floxis bid adapter. Maintenance updates add TypeScript declarations for Ftrack, shared ID public types, a new Realry bidder adapter, and changes to Fluct to signal autoplay capability and avoid CORS preflights. The release bundles source-code assets (zip and tar.gz) with timestamps. The update focuses on type definitions, telemetry, adapter maintenance and small feature/compatibility fixes relevant to header-bidding integrators and publisher ad stacks.
Prebid.js is a widely used open-source header-bidding library; this release adds identity typings, telemetry callbacks, a new bidder adapter and adapter maintenance that affect publisher integrations and header-bidding implementations but does not represent an industry-shifting change.
