A new version of Dropbox was released on Thursday without much fanfare, but Lion users will be happy to know that the update finally restores Finder integration for Apple's latest OS.

There are plenty of cloud storage options out there, but Dropbox's slick native filesystem integration is perhaps one of is most prized features. Installing the app on Mac OS X adds a Dropbox folder in the Finder. Dragging files here uploads them to your Dropbox in the cloud, and files added to your Dropbox are then automatically downloaded and mirrored locally.

With support for Mac OS X, Windows, Linux, and even your iOS, Android or BlackBerry mobile device, it makes it easy to transfer files from one device to the other, and all devices are automatically kept in sync.

Unfortunately for early Lion adopters, Dropbox's Finder integration was broken in Mac OS X 10.7. The only way to get it working was via beta development builds only available on its user forums.

Though Dropbox usually updates itself automatically in the background, TUAW notes that those updates can take as much as a week to filter out to all users. You can manually upgrade today, however, if you want to restore functionality posthaste.
