Ubuntu Linux 11.04 (Natty Narwhal) has just released on 28 April 2011.
This version brings some new experience to the user.
The installation process involves less number of step.
Its default desktop interface is a new Unity Desktop instead of the traditional GNOME Desktop. The experience is now more Macintosh alike. You can notice the sidebar on its left, which doesn't found in previous version of Ubuntu. It took me a while to figure out where to access to my favourite applications in this new desktop.
The default office productivity suite has also shifted from OpenOffice.org to LibreOffice.
