A timer ring that hands over from one expired timer to another now starts at full volume instead of ramping again from near silence.
The timer-vibrate migration only treats an install as fresh when the package was never updated and the store is empty. An updated install whose store was replaced after corruption, or an Auto Backup restore onto a new device, keeps the alarm default as before.
The Vibrate row now says whether it is on, and only when it is off adds that a silent timer still vibrates.
