May 2026: Delivered explicit ID-based Channel and Schema Registration in the MCAP writer API for foxglove/mcap, added thorough tests, and strengthened allocator stability and write-order guarantees. This work improves data integrity, enables stable cross-referencing of channels/schemas, and reduces runtime errors in multi-tenant and interleaved write scenarios.

Month 2026-04 was focused on delivering a cohesive Rust MCAP CLI feature set that significantly enhances ROS1 bag workflows, data reliability, and storage efficiency. The work improves developer and operator productivity by providing robust, test-covered commands with Go parity considerations and thorough documentation updates.

March 2026 focused on laying the foundation for a Rust-based MCAP CLI while maintaining the Go CLI as the production reference. Delivered an experimental Rust CLI scaffold, established a Cargo workspace, and wired core command dispatch to support incremental parity work. Implemented initial MCAP CLI commands and started validating command shapes and versioning integration, paving the way for scalable Rust-based tooling and ecosystem alignment.

February 2026 monthly summary for Foxglove repositories. Implemented automated PR review workflows in foxglove-sdk and fork-exclusion in foxglove/mcap, standardizing PR processes across repos. No major bug fixes recorded this month. Impact: faster PR reviews, reduced manual review overhead, clearer CI triggers, and improved governance of contributions. Technologies demonstrated: GitHub Actions, YAML CI workflows, PR automation, cross-repo collaboration.

Month 2025-08: Delivered targeted automation and documentation improvements across Foxglove repos, while correcting a documentation typo to prevent misguidance on Python package version updates. The work reduced manual review effort, clarified integrations (ROS/C++), and improved packaging guidance, enabling faster release cycles and smoother developer onboarding.

July 2025 monthly summary focused on delivering robust, scalable build and release pipelines for Foxglove repositories. Implemented Docker-based ROS development environment for foxglove-sdk to ensure consistent builds across ROS distributions and simplify setup. Enabled cross-platform CI cross-compilation and release artifacts for mcap-cli to streamline PR validation and tagged releases. These efforts enhance reproducibility, onboarding, and release reliability across both projects.

June 2025 monthly summary focusing on delivering a practical Python example for the Foxglove SDK to showcase end-to-end data logging capabilities and improve onboarding for SDK users. The work centered on a Python-based example that demonstrates logging images, schemaless JSON, JSON with jsonschema, and custom protobuf messages, with tooling support for build, lint, and dependency management.

May 2025 focused on branding consistency, asset management automation, and repository hygiene across foxglove/mcap and foxglove-sdk. Delivered automated branding asset generation and standardization for mCap branding, stabilized visuals by reverting unintended updates, and standardized crate naming in foxglove-sdk to align with Rust conventions. These efforts reduce maintenance overhead, improve cross-repo visual consistency, and establish a scalable foundation for branding pipelines and developer onboarding.

April 2025 monthly summary for foxglove-sdk: focused on stabilizing the publisher pipeline and expanding image format support. Achieved reliable release tagging and provenance on npm for schemas, and expanded documentation to include AVIF support. Result: improved release integrity, broader user capabilities, and stronger developer tooling.

Month: 2025-03. This month focused on stabilizing ROS integration, expanding SDK language support, and enhancing MCAP documentation. Delivered significant packaging improvements for ROS builds, announced Python and Rust SDK packages, and documented MessagePack encoding for MCAP.

February 2025 focused on laying a robust, multi-language SDK foundation, accelerating release cycles, and improving observability and onboarding. Delivered SDK foundation and build system modernization across Python, Rust, and TypeScript; implemented release automation with CI/CD improvements; maintained ROS/Jazzy CI integration; added Web UI session management and richer logging metadata; and refreshed documentation and onboarding materials (including MCAP CLI instructions). These changes reduce manual release steps, improve cross-language consistency, enhance ROS support, and accelerate developer adoption.

January 2025 Monthly Summary for foxglove-sdk focusing on infrastructure stability and cross-repo consistency.

Month 2024-11 focused on modernizing the Foxglove/mcap build tooling and CI to improve efficiency, reduce costs, and enhance developer experience. Delivered a Yarn v4 upgrade, removed interactive LFS tooling by default, and disabled Git LFS usage in CI, resulting in lower bandwidth usage and a simpler, more maintainable pipeline. No critical defects were reported; the changes establish a scalable, reproducible CI/CD path and demonstrate strong DevOps practices. Business impact includes faster feedback cycles, reduced infrastructure costs, and improved developer productivity.
