Dropbox 2.0 is available to download. The biggest change in version 2.0 of Dropbox is a brand new style for the system tray menu in Windows version and a new drop down menu in Mac OS X version.
Dropbox now features a live timeline of updates to your Dropbox, including sharing requests from other users. Think of it as a mini Notification Center, just for your Dropbox: You can quickly see what files have been updated and when. Click on any of the files, and you’ll be taken right to it in your Dropbox folder; you can even accept or decline sharing requests from the menu itself.
