Releases: prebid/prebid-server
v3.27.0
v3.26.0
Caution
A build pipeline issue prevented a DockerHub image from being generated for this release.
Future Breaking Changes
This release adds support for using operating system certificates for secure connections instead of embedded certificates. Prebid Server currently follows this approach for using embedded certificates for portability, which is complicated to maintain and is considered a bad practice.
We encourage testing the new certificates_use_system config in this release (defaults to false). This will become the default in Prebid Server 4.0 with no option to return to embedded certificates.
Networking Changes
We identified a networking configuration issue that can affect Prebid Server's outgoing connection queue. This release introduces new configuration options with the following default values. Please review and test these settings before upgrading to this version or newer.

v3.20.0
Known Issues
PubMatic Adapter: A regression was introduced in v3.20.0 where the bid.ext.prebid.type field is unintentionally omitted from bid responses. This may lead to downstream issues in some environments that expect this field (e.g., for media type detection).
A fix has been submitted via #4417 and included in v3.20.1. Please use v3.20.1 instead or apply the patch manually.
Changes
- New Adapter: Sparteo (#4275)
- Rules Engine Module: Phase 1 (#4407)
- Pubmatic: Set bid.meta.mediaType=video when bid.ext.ibv=true (#4189)
- Targeting: Add configurable targeting prefix (#4355)
- HTTP Fetcher: Implement RFC 3986 compatibility as optional (#4272)
- New Adapter: Nexx360 (#4286)
- Kobler: Remove sensitive device and user data (#4295)
