For May 2026, the akka-sdk focused on stabilizing runtime compatibility, expanding test coverage, and strengthening schema correctness to support reliable releases and downstream integration.

In 2024-12, delivered two focused features in akka/akka-sdk: Kalix Consumer SPI Support and SDK Runner Integration, aligning Event Sourced Entity changes and refactoring metadata handling to boost interoperability among Kalix components; Kalix Runtime Dependency Upgrade to a newer minor release to incorporate runtime bug fixes and new features. No major bugs fixed this month. Impact: improved interoperability and stability, enabling smoother integrations for Kalix-based workloads and reducing maintenance overhead by staying current with runtime. Skills demonstrated: SPI design, SDK runner integration, metadata refactor, dependency management, and Akka/Kalix ecosystem familiarity.

August 2024 monthly summary for akka-sdk focusing on stabilizing the Kalix runtime dependency. Upgraded Kalix runtime to a newer release and then executed a rollback to the prior state due to compatibility issues, ensuring runtime stability with no customer impact. Documented the rollback process and prepared a clear audit trail for future upgrades.
