DiddleBug 2.50beta5 released

What's new in 2.50beta5?

* uses MIDI files for alarms now
* supports LED and Vibrate alarms
* custom alarms for individual records
* overhauled repeat dialog/repeat handling
=> existing repeats will not be honored at the moment,
though they will be converted in the final release
* small internal fixes (should make DiddleBug more robust
with regards to API changes)
