Bugs & Fixes: Dropbox improves performance and setup
Though there wasn't anything particularly severe about the problems in the Dropbox 2.4.x desktop clients, the 2.6.2 version (as per the release notes) improves the speed of the UI quite a bit and offers improved setup—which you don't need if you're satisfied with your current version. You can now handily pause synching from the system tray pop-up and users are no longer unlinked from the online service if they roll back to a previous version. Of course, the only reason most users would want to roll back is a bug. So far, 2.6.2 seems relatively stable.
