+# Microbridge v0.3.10
+
+## Daemon recovery
+
+- Restore the bundled daemon automatically when the UI loses a daemon that was
+  owned by an older overlapping app process during login, update, or relaunch.
+- Preserve explicit standalone/headless daemon ownership while it remains
+  reachable; the GUI only starts its bundled daemon after that service exits.
+- Stop daemon recovery during clean app shutdown so no replacement child can be
+  orphaned as Microbridge exits.
+
+## Hardware status
+
+- Keep Codex Micro USB and Bluetooth detection available after daemon recovery,
+  including the native Claim, Retry, and Release actions added in v0.3.9.
+- Continue requesting only Input Monitoring for hardware control. Open at Login
+  may separately require approval in macOS Login Items.
