It was being dropped silently whenever System Haptics was switched off in iOS Settings, which is why some of you never felt anything. It no longer depends on that setting. Haptic Feedback is now Off, Light, Medium or Strong instead of a plain switch. BEEP and TONE play at the right pitch again, and no longer click at the start and end of each note. The key click sounds on the very first press and keeps a steady level. Speeds above Real no longer swallow keystrokes. The calculator was reading an ordinary tap as a long hold and cancelling it, so ENTER, XEQ, SIZE and other functions looked as though they did nothing. Every speed behaves now. Settings warns that above Real speed BEEP and TONE come out short and distorted, because the calculator makes sound faster than the speaker can play it.
