What's new
Root: iptables waits for the system lock, retries rejected rules (IPv6 too) and repairs drift found by health checks #121 Root: a cancelled check no longer closes the shared root shell; the log lists rejected UIDs #121 Firewall: no freeze when turning it on; cancelling the stop dialog no longer starts it Tile and widget: a tap while starting now stops it "Firewall did not stop" survives app restarts and names the right backend VPN permission prompt survives screen rotation
