Pre-releases of Precise Pangolin 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 as we work towards getting this LTS release ready.
What is new in ubuntu 12.04 alpha 1
uses the 3.2.0-2.5 Ubuntu kernel which is based on the recent 3.2-rc3 Linux kernel.

Vala rewritten Zeitgeist 0.9 alpha 1 has replaced the "old" Zeitgeist
Banshee, Tomboy and Gbrainy have been removed, meaning no Mono in the default Ubuntu install

Alpha 1 is the first in a series of milestone CD images that will be released throughout the Precise development cycle. The Alpha images
are known to be reasonably free of showstopper CD build or installer bugs, while representing a very recent snapshot of Precise. You can
download them here:
(Ubuntu Desktop, Server, ARM)
Additional images are also available at:
http://uec-images.ubuntu.com/releases/precise/alpha-1/ (Ubuntu Server Cloud and EC2)
Alpha 1 includes a number of software updates that are ready for wider testing. This is quite an early set of images, so you should expect
some bugs. For a more detailed description of the changes in the Alpha 1 release and the known bugs (which can save you the effort of reporting
a duplicate bug, or help you find proven workarounds)
