Many thanks to all our Safari users out there who've been patiently waiting for an update from us that will work with Snow Leopard (MacOS X 10.6). We're in the final stages of QA now, and hope to make the official version available on our download site next week.
In the meantime, if you've already upgraded to Snow Leopard and miss your Xmarks for Safari, we have a working pre-release version if you simply can't wait another moment. Please see this post to our GetSatisfaction forum for all the release notes and caveats, as well as the download link. A few thousand people have already downloaded it and report happiness, so check it out and see if you'd like to join them!
Once we've completed the regression suite with the latest bug fixes, we'll make it available from our download page. If you'd like to wait for the stable release, we'll post again here when it's ready.
Thanks again to all the users who've helped with early testing, and to all of you who've sent us words of encouragement as we've plowed through the myriad changes required for this upgrade.
