March 2026 delivered substantive remote-access capabilities and protocol hygiene improvements in foxglove-sdk, with a clear focus on business value: more scalable, reliable remote access and client publish workflows, plus a naming/refactor pass to align with LiveKit topics. The changes reduce runtime allocations, improve data-plane throughput, and standardize integration names across components and apps.

February 2026: Delivered cloud-enabled remote access capabilities and reliable channel messaging in foxglove-sdk, while improving testability and contributor onboarding. Key features implemented include Remote Access Cloud Connection to LiveKit with participant event handling and server-info messaging, and Channel Advertisements/Subscriptions with per-participant streams and buffering via control/data plane queues. A major refactor separated RemoteAccessSession state management from I/O, enabling isolated unit testing (SessionState) and aligning with FLE-241. Documentation was expanded with AGENTS.md to guide AI and human contributors. These changes collectively improve reliability, accelerate remote diagnostics with cloud access, streamline developer onboarding, and provide a stronger foundation for future remote-connectivity features.

Concise monthly summary for 2026-01: Delivered cross-language MCAP attachment writing support for foxglove-sdk, enabling C++ apps to write MCAP attachments via a new C API and Rust implementation, with tests. No major bugs fixed this month. This feature extends existing Rust MCAP support, improving data interchange, interoperability, and developer productivity across languages.

Month 2025-12: Delivered MCAP Attachments Support with Python Bindings for foxglove-sdk, enabling Python users to write MCAP attachments and store arbitrary binary data alongside messages in MCAP streams. This built on the existing Rust MCAP attachment support and extends Python bindings to expose MCAPWriter.attach, with tests and usage examples. Commit 2d03bc6dad75b4f102aefd02d5c77a0d1a2c0519 documents the change.

October 2025 performance summary for foxglove/foxglove-sdk.

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.
