Spring Data Elasticsearch now supports serverless deployments with a new ElasticsearchServerType enum, while Spring Boot patches a stale metadata reference that broke OTLP logging transport configuration.

Spring Data Elasticsearch shipped support for Elasticsearch Serverless [1], replacing a boolean flag with an ElasticsearchServerType enum and refreshing the default refreshInterval configuration. The same project also landed custom index options for @Field/@InnerField annotations [2], unlocking K-NN indexing and other vendor-specific features that the predefined attribute set couldn't reach. Over in Spring Boot, maintainers fixed a stale type reference for OTLP logging transport metadata [3] that pointed to a nonexistent class; the correct package lives in org.springframework.boot.opentelemetry.autoconfigure.logging.otlp, and this fix aligns 4.1.x with the correction already applied to 4.0.x [4]. Spring Data Elasticsearch also bumped to Elasticsearch 9.4.4 [5], and Spring Framework updated Javadoc to clarify that active profile registration order is now preserved in test contexts [6]. The integration layer picked up routine dependency updates: JRuby to 10.1.1.0 [7] and GraalVM to 25.0.4 [8].
