We've fixed the issues that popped up last week with Google Calendar Sync version 0.9.3.4, so we're going for the gusto and releasing version 0.9.3.5. We'll be slowly rolling out updates, but visit the Help Center (at http://www.google.com/support/calendar/bin/answer.py?answer=89955) to manually update your version.
