Ubuntu 16.04 LTS (Xenial Xerus) released

The Ubuntu team is very pleased to aounce 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 keel 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 QtMore...
