Sovrn recommends running the latest stable version of Prebid.js at all times. Prebid.js releases updates on a roughly weekly cadence, and each release can include bid adapter improvements, bug fixes, privacy compliance updates, and new features — all of which can directly affect your auction performance and revenue.
Why keeping Prebid.js up to date matters
Running an outdated version of Prebid.js is one of the most common and avoidable sources of lost revenue. Here's what staying current gets you:
Better auction performance. Bid adapter updates — including Sovrn's — are shipped through Prebid.js releases. If you're on an older version, you may be missing optimizations that improve bid response rates, reduce timeouts, or unlock new demand signals.
Privacy and compliance coverage. Prebid.js releases regularly incorporate updates to support evolving privacy regulations (GDPR, CCPA, and others). Running a stale version puts you at risk of non-compliance as the regulatory landscape changes.
Bug fixes. Issues discovered in the core library or in specific adapters are patched in new releases. If you're pinned to an old version, you won't receive those fixes — and those bugs can silently suppress bids or cause auction errors you'll never see in your logs.
Access to new features. Major version releases introduce capabilities like improved floor enforcement, enhanced user ID module support, and better video handling. Publishers on older versions simply don't have access to these tools.
How to track Sovrn-specific Prebid.js updates
You can monitor all Prebid.js releases that include Sovrn changes on the Sovrn-filtered GitHub releases page. This lets you see exactly what was added or fixed in Sovrn's bid adapter with each release.
For the full release history across all of Prebid.js, the Prebid.js release notes are a good reference for understanding what changed in core functionality across major and minor versions.
