What's New in v0.2.0

Per-Session Isolation

Each DSH session now owns an independent notebook, kernel, and working directory. Multiple sessions can run kernels simultaneously without state leakage.

Kernel Manager

A new toolbar popup lists all active kernels across sessions — session ID, kernel name, and status. Close any session's kernel directly from the manager.

Kernel Activity Indicator

A status bar shows whether the current session's kernel is active and warns when multiple sessions have kernels running (memory / resource awareness).

Parent Watchdog (Orphan Cleanup)

If dsh web is force-killed, the Python sidecar detects parent-process death and automatically shuts down its ipykernel — no orphan processes left behind.

  • POSIX (Linux/macOS): getppid() reparent detection
  • Windows: ctypes.OpenProcess query (NOT os.kill, which kills on Windows)

Bilingual UI (EN / 中文)

The entire interface now defaults to English with a one-click language toggle in the toolbar. Your language choice persists across sessions via localStorage.

Bug Fix

Fixed a critical crash where the parent watchdog's os.kill(parent, 0) on Windows called TerminateProcess and killed the dsh web main process ~2 seconds after any cell execution. Replaced with ctypes.OpenProcess(SYNCHRONIZE, ...) which queries without killing.
