Good morning, this is your VS Code developer briefing for May 22nd, 2026.
Twenty pull requests were merged yesterday with significant infrastructure improvements. Chulong Li merged a critical fix for Copilot CLI sessions hanging on patch apply after stream close, implementing a response stream router to handle steering reattachment when the original chat stream closes mid-turn. This resolves issue 316053 where sessions could hang indefinitely.
Rob Lourens addressed SSH agent host reconnection failures after sleep and network changes, adding periodic backstop reconciliation and auto-resume logic for paused reconnects. The fix prevents the three-hour reconnection delays users experienced after laptop wake events.
Sandeep Somavarapu preserved agents window workspace storage by preventing the shared process cleaner from deleting chat sessions, edits, and test results when the agents window isn't immediately open. This required moving workspace identifier utilities to prevent layer violations.
Vijay Upadya enhanced BYOK custom endpoints to respect user-supplied API keys and authorization headers, fixing duplicate credential issues with OpenAI-compatible endpoints behind gateways. Connor McDonald deferred Copilot steering consumption signals to keep steering messages visible until SDK responses resume.
Additional merged work includes terminal telemetry refactoring into a contrib module, feedback widget auto-hide improvements, and debug view overflow prevention. Harald Kirschner forwarded session sync settings to the Copilot SDK via remote flags.
What's next: Additional commit activity shows continued focus on agent host session handling and workspace storage reliability. The team appears to be strengthening the foundation for agent-based development workflows.
That's your VS Code update for today.
