Subject: Ubuntu 16.04 LTS (Xenial Xerus) released
The Ubuntu team is very pleased to announce our sixth long-term support release, Ubuntu 16.04 LTS for Desktop, Server, Cloud, and Core.
Codenamed "Xenial Xerus", 16.04 LTS continues Ubuntu's proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing new features and fixing bugs.
Ubuntu 16.04 LTS is the first long-term support release available for the new "s390x" architecture for IBM LinuxONE and z Systems, as well as introducing the new Ubuntu MATE community flavour.
The Linux kernel has been updated to the 4.4.6 longterm maintenance release, with the addition of ZFS-on-Linux, a combination of a volume manager and filesystem which enables efficient snapshots, copy-on-write cloning, continuous integrity checking against data corruption, automatic filesystem repair, and data compression.
Ubuntu Desktop has seen incremental improvements, with newer versions of GTK and Qt, updates to major packages like Firefox and LibreOffice, and stability improvements to Unity.
Ubuntu Server 16.04 LTS includes the Mitaka release of OpenStack, along with the new 2.0 versions of Juju, LXD, and MAAS to save devops teams time and headache when deploying distributed applications - whether on private clouds, public clouds, or on developer laptops.
Ubuntu 16.04 LTS introduces a new application format, the 'snap', which can be installed alongside traditional deb packages. These two packaging formats live quite comfortably next to one another and enable Ubuntu to maintain its existing processes for development and updates.
The newest Kubuntu, Lubuntu, Mythbuntu, Ubuntu GNOME, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, and Xubuntu are also being released today. More details can be found for these at their individual release notes:
Maintenance updates will be provided for 5 years for Ubuntu Desktop, Ubuntu Server, Ubuntu Cloud, Ubuntu Core, and Ubuntu Kylin. All the remaining flavours will be supported for 3 years.
