Version 1.8 * CalDAV: enumerate Webcal feeds (subscribed calendars) * Webcal feeds: integrate with ICSdroid (or other Webcal apps) – you can now subscribe to and unsubscribe from CalDAV-propagated Webcal feeds over ICSdroid directly from DAVdroid * sync intervals: remove 5 min and 10 min (not allowed in recent Android versions anymore for battery saving reasons), added 30 min * minor bug fixes and optimizations
