2026-01 monthly work summary for ros/rosdistro focusing on release metadata updates for agnocast distribution (v2.1.2-1).

September 2025: Delivered a key distribution enhancement for ros/rosdistro by introducing a source entry for the callback_isolated_executor and integrating a corresponding executor into the distribution. This improves callback isolation, reliability, and scalability across downstream packages, contributing to more predictable runtime behavior and easier maintenance of complex asynchronous workflows.

Month: 2025-08 — Focused on deployment reliability and configuration correctness. Delivered a targeted stability improvement by aligning Agnocast deployment to the exact version declared in autoware.repos (2.1.2) across the Ansible-managed pipeline. Updated user-facing docs and defaults to reflect the version change, enabling traceability and reproducible deployments. Result: reduced drift between desired and actual production environments, with minimal change risk and preserved CI/CD integrity.

July 2025: Cross-repo Agnocast 2.1.1 upgrade and deployment alignment to ensure consistent, stable releases across autoware.universe and autoware. This work improves traceability, reduces deployment drift, and strengthens upstream/downstream coordination while maintaining clear CI/CD signals.

April 2025: Implemented end-to-end Agnocast integration across Autoware repos, enabling zero-copy middleware, lifecycle management, and container-level config for reliable deployment. Key packages: autoware.universe, autoware, and aip_launcher; environment-driven enablement for backward compatibility and Docker build adjustments.

March 2025 monthly summary: Delivered foundational Agnocast integration across ros/rosdistro and Autoware, enabling tracking and potential seamless integration of Agnocast as a middleware option. Key updates include adding a repository source entry for Agnocast in ros/rosdistro, integrating Agnocast as a zero-copy middleware in Autoware (including Ansible role, source build in autoware.repos, and Dockerfile updates), and reinforcing installation reliability by ensuring Linux kernel headers are installed prior to DKMS steps. These changes enhance modularity, deployment reliability, and potential performance gains from zero-copy middleware, positioning our stack for smoother external component integration and scalable deployments.
