April 2025 monthly summary for repository base/node focusing on core dependency maintenance across op-node, op-geth, and op-reth. This period centers on aligning Dockerfile-based dependencies to the latest specified versions to leverage new features, bug fixes, and performance improvements from upstream components. Two upgrade commits were executed to refresh version baselines and ensure build stability.

Month: 2025-01. Key feature delivered: op-geth dependency upgrade in Docker image for base/node. Updated the VERSION and COMMIT environment variables in the Dockerfile to use op-geth v1.101411.6, ensuring the node runs the latest client for improved security, stability, and performance.

Month: 2024-12. Focused on delivering up-to-date Docker images for the base/node repository and strengthening build tooling. Upgraded op-node, op-geth, and reth dependencies in Dockerfiles, ensured version/commit env vars reflect new releases, and integrated the just CLI into Docker builds for op-node and reth. These changes improve deployment stability, reproducibility, and alignment with upstream releases.

November 2024: Upgraded the base/node Dockerfiles to the latest stable Optimism stack, delivering improved security, stability, and deployment reliability. Implemented two linked upgrades: OP core stack upgrade to version 1.9.5 (#350) and subsequent upgrade to op-node 1.10.0, op-geth 1.101411.2, and op-reth 1.1.2 (#353). These changes ensure deployments run on current, tested releases with security updates and performance improvements across the stack.
