About Ubuntu

, 16.04 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.
Under the hood, there have been updates to many core packages, including a new 4.4-based kernel.
Support lifespan
Ubuntu 16.04 LTS will be supported for 5 years for Ubuntu Desktop, Ubuntu Server, Ubuntu Core, and Ubuntu Kylin. All other flavours will be supported for 3 years.
New features in 16.04 LTS
Snap application format
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
Updated Packages
As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from Debian's unstable branch; others have been explicitly pulled in for Ubuntu 16.04.
Linux kernel 4.4
Ubuntu 16.04 LTS is based on the long-term supported Linux release series 4.4.
Python 3
Python2 is not installed anymore by default on the server, cloud and the touch images, long live Python3! Python3 itself has been upgraded to the 3.5 series.
Golang 1.6
golang toolchain was upgraded to the 1.6 series, and gccgo was upgraded to the GCC 6.1 release candidate 1. Thus the same level of standard library and compiler features are provided by both compilers on all fully supported architectures.
OpenSSH 7.2p2
Recent OpenSSH releases disable several pieces of weak, legacy, and/or unsafe cryptography. If you are upgrading a system remotely over SSH, you should check that you are not relying on these to ensure that you will retain access after the upgrade.
Support for the legacy SSH version 1 protocol is disabled by default at compile time. Note that this also means that the Cipher keyword in ssh_config(5) is effectively no longer usable; use Ciphers instead for protocol 2. The open-sshclient package includes "ssh1", "scp1", and "ssh-keygen1" binaries which you can use if you have no alternative way to connect to an outdated SSH1-only server; please contact the server administrator or system vendor in such cases and ask them to upgrade.
Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is disabled by default at run-time. It may be re-enabled using the upstream instructions
Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by default at run-time. These may be re-enabled using the upstream instructions
Support for the legacy v00 cert format has been removed.
Several ciphers are disabled by default in ssh: blowfish-cbc, cast128-cbc, all arcfour variants and the rijndael-cbc aliases for AES.
GNU toolchain
glibc was updated to the 2.23 release, binutils to the 2.26 release, and GCC to a recent snapshot from the GCC 5 branch (post GCC 5.3.0).
Apt 1.2
Apt 1.2 includes the new privilege separation features introduced in Apt 1.1. Importantly, the unprivileged "_apt" user is now used when making outgoing network connections and parsing the results for the various apt transport methods (HTTP, HTTPS, FTP).
Ubuntu Desktop
The general theme for 16.04 on the desktop is one of bug fixes and incremental quality improvements.
General
GNOME is mostly upgraded to 3.18. GLib upgraded to to 2.48 (corresponding to GNOME 3.20)
GNOME Software replaces Ubuntu Software Center. This brings a faster store experience and moves our archive metadata in line with Debian. It has been renamed "Ubuntu Software" to improve recognition for Ubuntu Software Center users.
