v3.0.0

Welcome to Prebid Server 3.0!

There are not many features in this release, but it's a major infrastructure upgrade that host companies will need to review their configuration.

Infrastructure updates

• Java 21
• Vert.x 4.5.5
• Spring Boot 3.2.3
• Many library dependencies have had major upgrades
• JUnit 5 support (entire test suite migration will happen in the later version)
• MySQL and PostgreSQL clients now use prepared statements (c3p0, hikari and jdbc client were removed entirely)
  • PostgreSQL now fully supports SASL SCRAM-SHA-256
• Maven dependency reorganization: now all dependencies are defined at the root pom.xml level so that all child pom.xml can benefit from using the centralized dependency management section. This should help with dependency versioning inconsistency. Modules retain the right to add new dependencies if those dependencies are not creating conflicts. If the dependency is already present in the project, modules should declare their dependency without version tag so that version is synchronized with the project.

Feature additions/deprecations

• Switzerland has been added to the default list of countries considered to be in the European Economic Area. prebid/prebid-server#3678
• OpenRTB 2.6 field downgrade to 2.5 is now performed only for ext fields, see prebid/prebid-server#3613
• Programmatic Guaranteed feature was removed from the code base along with associated properties and metrics
• removed bidder url validations for urls with macros inside them
• The following bidder adapters were converted to the generic bidder alias: adrino, ccx, infytv, loopme, zeta_global_ssp
  • if you wish to continue to use aforementioned bidder adapters, please move their respective configuration from adapters.{bidder} to adapters.generic.aliases.{bidder}

Configuration changes

• The JDBC client was removed in favor of modern Async DB client. Please be aware of syntax differences between MySQL and PostgreSQL and update your queries if needed. The following properties might need to be changed if you use PostgreSQL:
  • settings.in-memory-cache.database-update.update-query
  • settings.in-memory-cache.database-update.amp-init-query
  • settings.in-memory-cache.database-update.amp-update-query
• auction.strict-app-site-dooh is now set to true by default - this means that any requests coming into Prebid Server that contain more than one of site/app/dooh will be rejected. It's known that there are still publishers that do this. Host companies may want to monitor the logs for rejections.
• privacy.gdpr.purposes.p4.eid.activity_transition is now false by default
• settings.database.provider-class has been removed. It's not needed by the Async DB client.

Note: there was a configuration change we had wanted to make but forgot to add to 3.0. PBS host companies may want to take the opportunity to review how they want to handle the default ortb.multiformat-supported adapter config.

Added properties

• settings.database.idle-connection-timeout - Set the idle timeout, time unit is seconds. Zero means don't timeout. This determines if a connection will timeout and be closed and get back to the pool if no data is received nor sent within the timeout.
• settings.database.enable-prepared-statement-caching - Enable caching of the prepared statements so that they can be reused. Defaults to false. Please be vary of the DB server limitations as cache instances is per-database-connection.
• settings.database.max-prepared-statement-cache-size - Set the maximum size of the prepared statement cache. Defaults to 256. Has any effect only when settings.database.enable-prepared-statement-caching is set to true. Please note that the cache size is multiplied by settings.database.pool-size.
• settings.in-memory-cache.jitter-seconds - jitter (in seconds) for settings.in-memory-cache.ttl-seconds parameter.

Removed properties

All of these configurations were related to Programmatic Guaranteed, which has been removed.

• admin-endpoints.deals-status.*
• admin-endpoints.lineitem-status.*
• admin-endpoints.force-deals-update.*
• admin-endpoints.e2eadmin.*
