June 2026 monthly summary for docker/cagent. Key features delivered include: 1) Stream lifecycle robustness with non-blocking StreamStopped, serialized channel operations, and idle-timeout handling; 2) MCP remote connections resilience with an always-reconnect policy after clean closes and improved toolset recovery; 3) OAuth dynamic client registration now advertises the refresh_token grant type; 4) Miro hosted MCP server example configuration with inline board skills and updated docs. Major bugs fixed include guards around in-flight channel close during teardown and race-free final delivery of StreamStopped. Tests covering streaming edge cases were added (idle timeout handling and context cancellation). Overall impact: increased reliability, reduced risk of deadlocks and hung streams, faster recovery from remote session failures, and better alignment with OAuth server expectations. Technologies demonstrated: Go concurrency (goroutines, channels, context cancellation), channel locking, HTTP transport integration and per-attempt cancellation, test coverage for streaming edge cases, and documentation/examples for onboarding.

Month 2026-05: Delivered targeted improvements across docker/cagent and docker/docs, prioritizing business value through developer experience, stability, and documentation. Implemented contributor workflow modernization and updated issue templates to accelerate triage and reduce support overhead. Fixed a memory-leak in the TUI render cache with a new finalize lifecycle and regression tests, addressing stability in long-running agent sessions. Improved CLI documentation rendering for the experimental notice to eliminate unnecessary markdown processing, delivering faster and more consistent documentation views. These efforts collectively reduced memory usage in active sessions, clarified contributor guidelines, and strengthened release confidence via focused testing and documentation improvements.

March 2026 — docker/cagent: Focused on stabilizing transcription workflows and multi-agent session handling. Key features delivered include proactive validation of OPENAI_API_KEY at Transcriber.Start() to yield clear errors when missing, and a robust persistence filter for sub-agent streaming events to preserve parent session integrity. These changes reduce user-facing errors, prevent corrupted message histories during task transfers, and improve session restoration reliability. Technologies demonstrated include Go-based error handling, event-driven session management, and enhanced persistence logic for multi-agent conversations.
