There is no longer a traditional CD-sized image, DVD or alternate image, but rather a single 800MB Ubuntu image that can be used from USB or DVD. Users who previously installed using LVM or full-disk encryption via the alternate CD will find that these installation targets are supported by the consolidated image in 12.10.
With the Ubuntu 12.10, ARM desktop images are now standard Ubuntu live images as known from other architectures. To install these images you should have a USB disk as target device.
The Ubuntu 12.10 Quantal Quetzal release includes the 3.5.0-17.28 Ubuntu Linux kernel which was based on the v3.5.5 upstream Linux kernel.

If you use web applications like Facebook, Gmail or Flickr, you’re in for a treat. You can now pin them to the Launcher on the Ubuntu desktop, so you can launch them with a single click. No more starting a browser, clicking on a bookmark and then logging in. Just go straight into the app, as if it was installed on your computer.
In Ubuntu, the Dash has always let you search your computer for your files, photos and videos. But now it does more than just search your computer - it can search all your online accounts too. So, once you’ve saved the login details in the ‘Online Accounts’ function, you can expect to see your Flickr photos, Google Drive documents and more in your search results, alongside the files on your computer.
Ubuntu aims to take the effort out of everything. Now, you can preview your search results in the Dash to see more options, without having to open more windows. Preview an album in the Ubuntu One Music Store and you’ll get the option to play tracks straight from the preview. And when you preview an app in the Ubuntu Software Centre, you can install it with just one more click.
The minimum memory requirement for Ubuntu 12.10 is 768 MB of memory and 5 GB of disk space 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.
