In March 2026, Rafael Delfin upgraded the AWS SDK for C++ to version 1.11.758 within the bazelbuild/bazel-central-registry repository, focusing on enhancing reliability and security for AWS-enabled workflows. He synchronized all submodules to match upstream release versions, ensuring compatibility and smoother downstream integration. Using C++ and the Bazel build system, Rafael applied best practices in dependency management and release engineering, carefully documenting changes for auditability. His work addressed the need for consistent, secure dependencies in cloud-based applications, demonstrating depth in managing complex submodule relationships and maintaining robust integration pipelines without introducing new bugs during the upgrade process.
