Fixed
• An occurrence you deleted from a repeating event stays deleted — through a re-timing, a backup and a restore.
• "Only this event" now saves your edit on calendars that have never synced, and deleting one from an event that doesn't repeat deletes the event.
• A reminder left on your account's default no longer goes off as the event starts.
• The widgets turn the page at midnight instead of leaving yesterday as "today".
• An event running past midnight can be dragged by either half.
• One event the calendar refuses no longer costs you the whole import, and an import cut short tells you how far it got.

Added
• Belarusian, Hungarian and Slovak, from community translators on Weblate.
