Under the hood, there have been updates to many core packages, including a new 3.16-based kernel, a new AppArmor with fine-grained socket control, and more.
Ubuntu Desktop has seen incremental improvements, with newer versions of GTK and Qt, updates to major packages like Firefox and LibreOffice, and improvements to Unity, including improved High-DPI display support.
Ubuntu Server 14.10 includes the Juno release of OpenStack, alongside deployment and management tools that save devops teams time when deploying distributed applications – whether on private clouds, public clouds, x86 or ARM servers, or on developer laptops. Several key server technologies, from MAAS to Ceph, have been updated to new upstream versions with a variety of new features.
The newest Kubuntu, Xubuntu, Lubuntu, Ubuntu GNOME, Ubuntu Kylin, and Ubuntu Studio are also being released today.
