Dropbox has released a major update for its pre-release Experimental Edition software. The v1.5.27 release has been rebuilt using Python 2.7, which should result in improved performance, and includes new Retina-ready graphics. It is also bundled with a simple installer and offers support for Mountain Lion's Notification Center. As this is the first release of a major new build, Dropbox has stressed that users should backup all of their data before installing. One major issue has also already been found, resulting in slow startup times on OS X.
