October 2025 performance summary for foxglove/foxglove-sdk. Delivered cross-language remote visualization capabilities and robust data handling, with targeted stability improvements across Windows and platform-specific builds. The work strengthened observability, data fidelity, and cross-language reuse while laying groundwork for future WebSocket server integration.

September 2025 monthly summary for foxglove-sdk development focused on expanding the WebSocket surface area and consolidating production-ready tooling for downstream integrations. The key delivery was a public WebSocket API exposure, enabling other components (e.g., the agent) to consume WebSocket protocol types and WebSocketClient via a stable, documented interface. The work included refactoring tests to production readiness, introducing a new dependency, and adjusting the module structure to support the new public API, with tests updated to reflect the changes.

July 2025 monthly summary for foxglove-sdk focused on reliability and correctness of channel advertisement tracking. Implemented a bug fix to prevent unadvertisement of channels that failed to advertise, refactored tracking to consider only explicitly advertised channels, introduced a Set-based filtering approach for efficiency, and expanded test coverage to validate behavior. Deliverables align with business value by ensuring accurate channel lifecycle state, reducing false unadvertisements, and improving fault tolerance in advertisement flows.

June 2025: Delivered stability improvements and developer experience gains for foxglove-sdk. Key achievements include a C++ crash fix for zero-length vectors and header cleanup, new Rust and C++ data-logging examples with build/run support, and CI stability fixes for Rust 1.88 clippy lint issues. These changes reduce runtime crashes, streamline SDK adoption, and improve PR validation, with visible business value in reliability, documentation, and onboarding.

May 2025 monthly summary: Focused on reliability, performance, and developer experience across Foxglove MCAP and SDK repos. Implemented critical fixes, library upgrades, and new bindings and examples to enable broader adoption and more robust data logging.

April 2025 — Foxglove SDK delivered meaningful cross-language improvements and reliability enhancements that drive business value and developer productivity. Key features include a high-performance logging subsystem with a type-safe macro, a new cross-language Timestamp::now() utility, and modernized C/C++ APIs with improved error handling and context management. We also stabilized CI builds by adjusting sccache usage and CMake configurations. These changes reduce operational risk, improve observability, and simplify integration for Python, Rust, and C/C++ consumers.

March 2025 monthly summary focusing on key accomplishments across Foxglove SDK and MCAP projects. Delivered new data export capabilities, reliability improvements, and performance optimizations that enhance release readiness, debugging efficiency, and runtime performance. Highlights include MCAP writer integration in the C/C++ interface, enhanced Python logging, a flaky test reliability fix, and a performance optimization in MCAP reading paths. Emphasis on delivering business value through robust tooling, better observability, and faster data processing.

February 2025: Delivered major real-time messaging and parameter protocol enhancements in foxglove-sdk. Implemented WebSocket server improvements with client interaction tracking, backpressure-aware status messaging, connection graphs, and protective measures against slow clients. Rolled out comprehensive parameter protocol support in the Rust SDK (subscriptions, unsubscriptions, get/set) with corresponding WebSocket/server updates and a bug fix, aligning behavior with the Python server. These changes improved reliability, observability, and cross-language consistency, enabling more robust real-time workflows and faster developer iteration.
