Spring Boot shipped a major build cache upgrade that lets you store container images in registries and share them across hosts, while deprecating TestRestTemplate in favor of the newer RestTestClient.

The image-based build cache feature [1] integrates with both Maven and Gradle plugins, using the lifecycle's `-cache-image` argument to store build artifacts in container registries. This is a significant productivity win for teams running distributed builds. Spring Boot also deprecated `TestRestTemplate` [2] in favor of RestTestClient, with a new `TrustAllTlsRequestFactory` testing utility [5] to handle TLS certificate validation in tests. Across the Spring portfolio, cleanup continues: spring-tools removed its old Azure plugin dashboard [8] and fixed duplicate "the" typos across multiple repos [ref:4, ref:7]. Spring Kafka updated documentation anchors [6] after a recent rename of partition assignment sections, marked for automatic backport to 4.0.x. Spring Data Elasticsearch added a new documentation section on server type configuration [7]. All told, 29 commits and 9 PRs flowed through the ecosystem overnight.

Action items

→ Review image-based build cache option for distributed CI/CD pipelines spring-projects/spring-boot [plan]
→ Migrate TestRestTemplate usage to RestTestClient in test suites spring-projects/spring-boot [plan]
→ Update Spring Kafka anchor references if using 4.0.x branch spring-projects/spring-kafka [monitor]
