I've decided to release another version of Aperture2Gmail today. Normally I don't like to release updates so close together, however, there were a couple of issues I felt were too pressing . So here it is!
Aperture2Gmail version 0.7 is now available. This update improves stability when retrieving contacts and is recommended for all users. More information about the specific fixes can be found in the changelog. Please feel free to post to the notoptimal.net group with any problems or questions.
