In April 2022 Ubuntu 22.04, codename 'Jammy Jellyfish' is being released and brings a whole host of new features and updates to the usual packages you likely use every day on your servers.

With this being an LTS release it's officially supported by ServerAuth, and we've already rolled out support for it in your control panel.

What is an LTS Release

Every two years Ubuntu releases what's known as a Long Term Support version. These are versions that will receive updates for a longer period than a standard release. In Ubuntu's case, they provide updates to LTS releases for five years, and Extended Security Maintenance (ESM) for ten years, meaning Jammy Jellyfish will still have updates released up to 2032.

For server environments, this is ideal as it gives long-term assurance that your operating system is still being maintained.

Updated packages

There are thousands of package updates in this release, but we'll focus on a few of the most common and widely used packages on servers:

PHP 8.1

Ubuntu 22.04 makes the jump to the latest version of PHP, bringing some fantastic enhancements, such as upgrades to the programming languages built-in 'Opcache' system, providing a speed boost of up to 8%.

Other features in this release include; Fibres (allowing the creation of interruptable functions), read-only properties, new return types, enums, and more.

Ruby 3.0

Released back in late 2020, v3 includes CPU and memory performance improvements, with a new 'MJIT' compiler sporting a range of security improvements, enhancements to the garbage collector, parallel process updates with the new 'fibers' system, and a range of new syntax improvements.

Python 3.10

Fresh off of its release on March 17th, 2022, Python 3.10 just about made it into the 22.02 release! This version brings a range of new syntax features, new type features, improvements to the interpreter and raises the minimum OpenSSL version to 1.1.1.

Golang 1.18

Go has become a widely used, lightweight programming language. The latest release was a major update and brought features such as Generics, which was dubbed the 'most significant change to the Go programming language since its release in 2012'. Users of ARM64, PowerPC64, and Apple Silicon will also see performance improvements of up to 20%.

Under the hood updates and improvements

In addition to the usual package upgrades, The core Ubuntu OS is set for a few new features and upgrades.

  • The Linux kernel has been updated to v5.15 (Although some pre-built desktops and laptops running Ubuntu Desktop are likely to ship with v5.17)
  • OpenSSL has been upgraded to v3.0, released in September 2021.
  • Improved support for Raspberry Pi, with the Pi 4B 2GB and above now fully supported.
  • A revamped installer GUI

Desktop updates

For Ubuntu Desktop users, Gnome has been updated to v42 and sports a new orange color scheme. The new Nautilus 42 file manager includes a bunch of improvements to the UI and is noticeably different from previous releases.

Other updates include:

  • The Yara GTK desktop theme has had a range of updates and refinements
  • All major included desktop apps have been upgraded to their latest stable versions

When will it be released?

The new version will go through a few stages of pre-release before the final, stable version is made available. Nightly builds are available already for those keen to try out the new version.
