May 2025 focused on delivering business value through automated releases, build modernization, reliability improvements, and expanded Dapr workflow samples across Java SDKs and quickstarts. This period delivered end-to-end release automation, streamlined builds, and richer developer patterns with Spring Boot compatibility.

In March 2025, the dapr/java-sdk delivered a set of high-value features, reliability improvements, and developer-experience enhancements that collectively reduce deployment risk and accelerate feedback loops. Key features include Spring Boot Dapr integration examples (producer/consumer) with pub/sub, state, and workflow capabilities, augmented by Testcontainers-based HTTP middleware pipelines (AppHttpPipeline) and YAML-serializable configurations for local development and Kubernetes deployment scenarios. Major reliability fixes include preventing deployments from being skipped (#1246) and correcting the Maven deploy profile invocation order to ensure -Pdeploy-profile is applied reliably in CI. The CI/CD workflow was substantially enhanced: switching to Nexus staging for deployments, properly ordering deploy commands, increasing build timeouts, reusing Nexus URLs, skip tests during OSSRH deploys, and updating the Docker version in CI to reduce flaky tests. In the test infrastructure, Spring Boot was upgraded to 3.4.3 project-wide, test startup was refactored for reliability, Dapr container integration tests gained awaitability for the placement server, and container reuse was enabled to speed up test execution. A small but meaningful code-cleanup was performed by removing unused dead code, improving maintainability. Documentation was updated to include Podman usage instructions and registry configuration to broaden runtime support across Kubernetes environments.
