Pre-releases of Natty are *not* encouraged for anyone needing a stable system or anyone who is not comfortable running into occasional, even frequent breakage. They are, however, recommended for Ubuntu developers and those who want to help in testing, reporting, and fixing bugs.
Alpha 2 is the second in a series of milestone CD images that will be released throughout the Natty development cycle. New packages showing up for the first time include:
* LibreOffice 3.3 (has replaced OpenOffice.org 3.2)
* X.org Server 1.10 and Mesa 7.10
* Linux Kernel 2.6.38-rc2.
Unity is now the default in the Ubuntu Desktop session. It is only partially implemented at this stage, so keep an eye on the daily builds, new features and bug fixes are emerging daily!
Alpha 2 includes a number of software updates that are ready for wider testing. Please refer to http://www.ubuntu.com/testing/natty/alpha2 for more detailed information on the new features and known issues with this development release of Natty.
