The last build introduced a problem that prevented some users from completing a sync. The fix for that problem along with several other improvements is included in Spanning Sync v2.0b Build 342, which is now available for download. All beta users are encouraged to upgrade as soon as possible.
What's New in Build 342
Fixes some causes of the "you referenced a relationship without pushing it" error
Fixes the "inconsistent data" alert thatĀ Apple Sync Services would display in some cases
Prevents all contacts from being deleted from Google when syncing with contact syncing turned off and choosing to replace contact data
Lest you think all of our bug fixes go into client releases, we just pushed an update to the live servers that fixes a bug that was causing group membership information to get removed when contact updates were sunc from Address Book to Google. That is all. Enjoy your Friday night. :-)
