Canonical has just released Ubuntu 13.10 (Saucy Salamander) to the public as scheduled. This is their latest non-LTS release before Ubuntu 14.04 which is going to be declared as LTS version.
Canonical is also providing Cloud-based service based on Ubuntu with a new service called Ubuntu OpenStack and for the first time ever, they also released it on the phone with Ubuntu Touch.
Check out the features page to find out more about their features and finally, head to the download page if you want to start downloading the ISOs. I have downloaded all of the ISOs on our campus ISO Server which is located here: http://iso.ukdw.ac.id/ubuntu/13.10/.
