May 2026 monthly summary focused on stabilizing the audio pipeline in pipecat and improving resilience to remote disconnects. Core outcome: audio processing remains bounded by a timeout, preventing blocking writes and ensuring timely shutdown when peer disconnects mid-stream. A changelog entry was added to document the change. Consistent with ongoing reliability and maintainability efforts across the repository pipecat-ai/pipecat.

April 2026 monthly summary for pipecat-ai/pipecat.
