February 2026 monthly summary for posit-dev/publisher: Reliability-focused fix to prevent auto-restarts during intentional shutdowns by introducing a stopping flag in the Server class and hardening the shutdown path. The change addresses a race condition where stop() or dispose() could trigger a close event that restarted the server. The patch also guards the status bar API call in stop() with a try-catch to gracefully handle VS Code shutdown scenarios. These updates improve uptime, reduce unintended downtime, and simplify maintenance during shutdown sequences.
