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.
