CloudPull 2.1.9 is now available through this web site and through the in-app software update mechanism.
Google recently made a change to the way Google Calendar data is served via CalDAV that rendered CloudPull unable to find events in calendar feeds. CloudPull should have been able to handle this change, but it was not. This update fixes that. Since the problem introduces the possibility that the most recent calendar backup may not include the events, the first time this version is run it will back up fresh copies of your calendars. This update also fixes a bug in which CloudPull would fail to back up calendars that had no events.
These fixes will be available in the Mac App Store editions as soon as possible. For customers running Snow Leopard (Mac OS X 10.6), CloudPull 1.5.9 also includes these fixes and is available for download.
Update February 8, 2013: This fix is now available in the Free Mac App Store Edition. The version number for that edition is version 2.2.1. The update containing this fix for the Premium Mac App Store Edition hit a bump in the review process; it has been resubmitted and will be available as soon as possible.
Update February 14, 2013: This fix is now available in both Mac App Store editions.
