BusyMac has released BusyCal 2.0.2, a minor update that puts paid to several bugs. The update fixes some unspecified Google Calendar syncing bugs, a bug that prevented past due to-do items from showing in the To Do List, bootstrapping bugs with Daylite and Zimbra CalDAV Servers, and a bug that occurred when entering start times between 0001-0059 in 24-hour time. It also adds an option to print multiple months/weeks when viewing a custom number of weeks/days. ($49.99 new, but currently selling for $29.99 solely via the Mac App Store, free update, 8.3 MB, release notes)
