Ubuntu 13.04 Released

Written for Ubuntu by Colin Watson on 2013-04-25

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 Grizzly 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.
