The final version of Ubuntu 13.04 has been released. Here the announcement:



The Ubuntu team is very pleased to announce the release of Ubuntu 13.04
for Desktop, Server, Cloud, and Core products.

Codenamed "Raring Ringtail", 13.04 continues Ubuntu's proud tradition
of integrating the latest and greatest open source technologies into a
high-quality, easy-to-use Linux distribution. This release cycle has
seen a significant push toward daily quality, which has allowed most
developers and users to participate more actively throughout the cycle,
and we feel this also shows in the final quality of this release.

Along with performance improvements to Unity, updates to common desktop
packages, and updated core and toolchain components, Ubuntu 13.04 also
includes the new Friends service, to consolidate all social networking
accounts via Ubuntu Online Accounts. Also included is a tech preview
of Upstart's new user session feature.

Ubuntu Server 13.04 includes the Grizzy 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, and a preview of the new Go
rewrite of Juju is available in the backports repository.
