You can download Ubuntu 12.10 Quantal Quetzal
As we advanced yesterday , Quetzal Quantal Ubuntu 12.10 is now available for download . The ISO weighs 753 MB and even the new version of this distribution does not bring too revolutionary changes, it does have several updates that are worth reviewing.
In code, Quantal Quetzal integrates Linux kernel 2.5.4, with some applications and libraries in GNOME 3.6, although this shell is not present in the operating system, opting instead for the Unity interface as it has been doing since some time.
Now, running Ubuntu, one of the main changes is the increased integration of the cloud operating system, and the way the menu (dash) of Unity interacts with the content you have stored on the machine, and the cloud. The dash can now search and browse both the hard disk content and the web. Quantal Quetzal includes an API that allows you to search services like Google Drive, Flickr or Facebook, for example.
Also when looking for music, the results appear in the songs you have on your disk, and options to purchase songs in Ubuntu One and Amazon. This feature has received considerable criticism because it would violate user privacy, but is one way that Canonical is trying to monetize the operating system. If you end user of Ubuntu buying something on Amazon following a search, Canonical will receive a percentage of the sale.
In addition, version 12.10 includes the ability to create “desktop applications” web applications you use most. For example, instead of opening the browser to access your email or your Twitter account, you can create an icon in Unity will work directly with Firefox to open the site you want to see.
