Introduction

The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the open source community has to offer. Ubuntu 11.04 "Natty Narwhal" Beta 2 gives a preview of the next version of Ubuntu.
Naming Changes

Ubuntu Netbook Edition and Ubuntu Desktop Edition have been combined into a single Edition called simply "Ubuntu" (with no "Edition").

Ubuntu Server Edition has been renamed to simply "Ubuntu Server" (again, the "Edition" has been dropped).
Get Ubuntu 11.04
Upgrade from Ubuntu 10.10

To upgrade from Ubuntu 10.10 on a desktop system, press Alt+F2, type in "update-manager -d" (without the quotes), and press Enter. Update Manager will open up and display the message, "New distribution release '11.04' is available." Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu 10.10 on a server system, install the package update-manager-core if it is not already installed. Then execute the command sudo do-release-upgrade -d, and follow the on-screen instructions. Note that the server upgrade is now more robust, and thus will utilize GNU screen and automatically re-attach in case unexpected problems arise, e.g. dropped connection problems.

The same instructions apply to all other editions of Ubuntu (such as Kubuntu, Xubuntu, etc.)
