The new version of WC was released yesterday evening. We have tested our theme with WC release candidates. We do the final test with the new version because WC developers made some changes that RC does not have. We plan new theme update within a day. New theme version will be compatible with WC 3.0. Don’t update WC plugin before theme update.
Also, before update any plugin you need to be sure that theme and other plugins that you use are compatible with new version.
