v13.04-rev279 [Jan 6, 2013]
Includes the 3.8.0-19.29 Ubuntu Linux kernel which was based on the v3.8.8 upstream Linux kernel.
Automatic Apport crash reporting has been enabled by default again to catch problems early on. It now checks for duplicates on the client side, which will avoid uploading debug data and creating Launchpad bug reports unnecessarily in many cases now.
v12.10-rev273 [Jun 12, 2012]
-Web apps
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.
-Dash previews
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.
-Online search
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.
