Important Updates

As of Broadleaf Release Train 3.0.0-GA, all microservices have been upgraded to support Spring Boot 4.1 and Java 25.

Avoid threadlocal context issues for access tokens on webclient builders in Spring Boot 4, backwards compatible with Spring Boot 3.5.

Fixed an error for Facets that occurs if the Field value is empty and the variant type request is sent without the correct field ID.
Fixed an issue with ModelMapper caching causing issues that prevents extended domains from mapping as intended.
Fixed a time-of-check-to-time-of-use (TOCTOU) race in the ZooKeeper lock failure monitor introduced by the Spring Boot 4 migration, where a stale getChildren() snapshot could be compared against a lockOwner from a different ownership episode and spuriously publish a ZookeeperLockFailedEvent during normal lock handoff.
Increased the specificity of the IndexableTypeDocumentBuilder bean return type to avoid ambiguous @ConditionalOnMissingBean registration when a class implements multiple interfaces.
Updated external provider WebClient calls to merge multi-value HTTP headers from getHeaders(ContextInfo) instead of overwriting same-named headers, fixing compatibility across Spring Boot 3.5 & 4.
