What's New in XEQ41
0.8.4
September 13, 2026
• Fixed: tapping a module that cannot go in — one already plugged, or a peripheral this app does not emulate — switched the calculator off and on. It now says why, and leaves the calculator running. • Fixed: a file arriving by AirDrop while the calculator was busy could be lost. • A damaged saved machine can no longer take the app down when it launches.
