February 2026: Focused on stabilizing and modernizing the Eclipse Mosquitto Docker image in influxdata/official-images. Delivered two upgrade steps: 2.1.1 with Alpine 3.23 support and OCI-compatible labels, followed by 2.1.2 to preserve compatibility and current tagging. These upgrades consolidate image maintenance, reduce drift, and improve build reproducibility and supportability across deployments. No user-impacting bugs were identified; the work reduces maintenance overhead and enhances security and stability for dependent MQTT workloads.

January 2026 highlights two cross-repo improvements that boost Docker image build performance, caching, and release hygiene for Mosquitto-related images across OSS-Fuzz and official Docker images. In google/oss-fuzz, implemented Docker build optimization by integrating the libprotobuf-mutator build into the Dockerfile and corrected the Mosquitto repository path, preparing for default sanitizers and future sanitizer workflows. In influxdata/official-images, upgraded the Eclipse Mosquitto library to 2.1.0 with updated repository URL, commit hashes, and a refined tagging structure to improve traceability and maintainability of downstream images. These changes reduce build times, improve caching determinism, and strengthen release traceability and security testing readiness across the pipeline.

July 2025 monthly summary for influxdata/official-images focused on aligning release version tags to the Eclipse Mosquitto 2.0.22 stable release and ensuring commit references reflect the latest tag. This work improved release accuracy and deployment reliability across downstream environments.

May 2025 monthly summary for influxdata/official-images: Delivered a base image upgrade for the Eclipse-Mosquitto Docker image to Alpine 3.22, aligning with the latest security patches and components. This update was implemented in the 1.6 image via commit 0a0a89078d70484375e356104e0a098897e68b1a, and ensures a more secure, stable foundation for downstream deployments.

March 2025 — Maintained and improved image version integrity in influxdata/official-images. Focused on aligning the eclipse-mosquitto Docker image tag to the 2.0.21 release, ensuring builds and deployments pull the correct commit. This involved updating the tag-to-commit mapping and referencing the specific commit 44fc151041f6dab7679bf0ccb32eebf09a93dfe2 for eclipse-mosquitto 2.0.21. The change reduces risk of deploying incorrect images and enhances CI/CD reproducibility across environments.
