Ubuntu 11.04 “Natty Narwhal” has been released bringing the latest Firefox 4.0 as the standard web browser and the updates don't end here.
Unity is now the default Ubuntu desktop session. The Unity launcher has many new features, including drag and drop re-ordering of launcher icons, full keyboard navigation support, launcher activation through keyboard shortcuts, right-click context menu quick-list and switching between running applications.
The Ubuntu One control panel now allows selective syncing, and the launcher icon now displays sync progress. File syncing speed has been improved as well.
The Ubuntu Software Center now allows users to "rate & review" installed applications, share reviews via integration with social networking services added into Gwibber, and has other usability improvements.
GNOME programs now use a new scrollbar which takes less screen space.
Preparing your computer for Ubuntu is now much simpler, with a wider range of disk setup options. Each of these are detailed at length to provide you with a clear understanding of the actions that will take place with your selection.
You can now reinstall or upgrade an existing copy of Ubuntu with the Desktop CD installer, provided that your computer is connected to the Internet.

The minimum memory requirement for Ubuntu 11.04 is 384 MB of memory for Ubuntu Desktop. Note that some of your system's memory may be unavailable due to being used by the graphics card. If your computer has only the minimum amount of memory, the installation process will take longer than normal; however, it will complete successfully, and the system will perform adequately once installed.
The minimum memory requirement for Ubuntu Server 11.04 is 128 MB of memory.
Systems with less memory may be able to select "Install Ubuntu" from the boot menu to run just the installer, rather than the whole desktop, or may be able to use the alternate install CD.
To upgrade from Ubuntu 10.10 on a desktop system, press Alt+F2, type in "update-manager" (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, 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.)
