Ubuntu 22.04 LTS released with performance and security improvements

Canonical has announced the general availability of version 22.04 of the Ubuntu Linux distribution, codenamed 'Jammy Jellyfish', which brings better hardware support and an improved security baseline.

Ubuntu is the world's most popular Linux distribution for consumers. It focuses on ease of use, automation, extensive hardware support, and a default configuration that enhances the user's out-of-the-box experience.

22.04 is an long-term support (LTS) release, so security updates will be available for the next five years, making it suitable for those who need a stable system with minimal maintenance requirements.

Moreover, this is the first LTS release where the entire Raspberry Pi device portfolio is supported, building upon the work that started back in Ubuntu 20.10, a release dedicated to the popular single-board computers.

Release highlights

While Canonical offers multiple Ubuntu editions of each release for different deployment purposes, among the highlights in 22.04 LTS are:

Confidential Computing for upgraded data protection and privacy in cloud operations.
AWS Graviton optimization for better performance on Arm.
Support for the entire range of the Raspberry Pi 4 device portfolio.
Upgraded WSL features.
Readily available NVIDIA GPU drivers and NVIDIA AI Enterprise suite support.
Introduction of real-time kernel option for ultra-low latency in telco and industrial applications.
Migration to OpenSSL v3 for elevated security and new cryptographic algorithms.
Added Rust for memory-safe system-level programming.
RDP support out of the box (VNC still available)
nftables is now the default backend for the firewall.
ssh-rsa is now disabled by default in OpenSSH
Using Linux kernel version 5.15
Move to GNOME 42 desktop environment featuring power profiles, upgraded workspace management, and frame rate optimizations on weaker hardware.

Grab your spin

If you're interested in trying out Ubuntu, you may pick the edition that suits your need from Canonical's download portal. Ubuntu comes available in Desktop, Server, Cloud, and IoT (Core) editions.

Additionally, Ubuntu offers the so-called "flavors", essentially the same OS base with a different desktop environment, suitable for those who don't like the default GNOME Shell.

For example, Kubuntu uses the options-rich KDE with the Plasma desktop, Xubuntu has the lightweight Xfce environment, and Ubuntu Studio comes pre-loaded with a set of media production tools.
