Ubuntu 22.04 LTS “Jammy Jellyfish” – New Features and Release Details

This article contains details about new features of Ubuntu 22.04 LTS “Jammy Jellyfish”. We give you all the relevant information to keep you up to date.

The Ubuntu LTS releases are rare, and they are significant because they set the course for the next five years for everyone – from you/to me to the enterprises who run thousands of machines/virtual systems with Ubuntu.

From the feature standpoint, you get GNOME 42, Linux Kernel 5.15, new Accent colour, updated applications and many intrinsic features that make it another historic LTS release of Ubuntu. We intend to give you a summary of those features while keeping this post updated until the final release so that you get a single source of all the information about Ubuntu 22.04 LTS.

Let’s take a look at the official schedule.

Ubuntu 22.04 LTS – Release Schedule

Ubuntu 22.04 LTS Jammy Jellyfish releases on April 21, 2022. Before that, the Ubuntu team should meet the following milestones.

February 24, 2022: Feature Freeze
March 17, 2022: UI Freeze
March 31, 2022: Beta Release
April 21, 2022: Final Release

This release is supported until April 2027.

Ubuntu 22.04 – New Features

Kernel

Linux Kernel 5.15 LTS will be the initial Kernel for this long term Ubuntu release. Released around Halloween 2021 last year, Linux Kernel 5.15 brings several essential improvements. Usual new driver and hardware updates across processor, GPU, network, and file system families. This Kernel also brings the fast NTFS3 driver from Paragon Software, mainlined in this version. Other notable benefits of this Kernel are Apple M1 SOC support, in-Kernel SMB driver, Realtech Wi-Fi driver support for RTL8188EU chipset, etc. You can read the details about what this Kernel has to offer in our Linux Kernel 5.15 coverage.

GNOME Desktop Version

There is still discussion on the base version of GNOME in this LTS release. However, it is confirmed that GNOME 42 will be the default gnome-shell version.

But there is a catch.

You must have heard that GNOME 42 is bringing an updated version of GTK4 applications with libadwaita library-port for those apps. The Ubuntu desktop team plans for GNOME 42, but the default installed applications remain based on GTK3. A sensible decision from the desktop team, in my opinion. Because moving to GNOME 42 + GTK4 + libadwaita ports – all these require a lot of regression tests. Not to mention the risk of breaking things here and there. This is too much of an overhead for the LTS release, a default choice for most of the user base and arguably the most downloaded/upgraded version.

Look and Feel

On the look-n-feel side, there is a change in the Yaru GTK theme base colour, which is the default theme for Ubuntu. The usual Purple accent colour is changing to Orange. Now, be cautious that it may feel like staggering orange shades. Look at this screenshot.

New Accent Color

Jammy Jellyfish brings the accent colour for the first time on the Ubuntu desktop. It applies to both light and dark themes. This feature is accessible via the Appearance section.

New logo and Plymouth

Canonical – the company behind Ubuntu announced to change its official logo after a decade from this release onwards. The new logo is more simple with a large vertical rectangle variant. It is displayed in the boot animation alongside all application places.

New default wallpaper

Following the tradition, this version features a nice and classy default wallpaper that depicts the official Jellyfish mascot.

Packages and Application Updates

Besides the above changes, core packages default applications bring their latest stable version. Here’s a quick list.

Python 3.10
Php8.1
Ruby 3.0
Thunderbird 91.5
Firefox 96.0
LibreOffice 7.2.5
PulseAudio 15.0
NetworkManager 1.32

And the new Yaru icon theme in LibreOffice looks stunning, though.

Updating from Ubuntu 20.04 LTS?

In general, if you plan to switch to this LTS version from Ubuntu 21.10, you should notice a few items of change. But if you are planning to upgrade from prior Ubuntu 20.04 LTS – then a lot for you to experience. For example, you get a horizontal workspace horizontal app launcher, those introduced since GNOME 40.

Also, other notable differences or rather new features are the power profiles menu in the top bar, multitasking option in settings and performance improvements of GNOME Shell and Mutter.

Looking at the upgrade challenges, we published a dedicated LTS to LTS spotter guide for you. Read it here.

Difference Between Ubuntu 22.04 and Ubuntu 20.04 LTS

Ubuntu Official Flavors

Alongside the base version, the official Ubuntu flavours are getting their latest versions of their respective desktop environments in this LTS version. Apart from KDE Plasma, most desktops remained with their last stable release for more than a year. So, you may not experience much of a difference.

Here’s a quick summary and more information about the flavours.

If you want a super-unstable copy of Canary Build, you can get it from the below link. I would not recommend using this Canary .ISO at all unless you have plenty of time to play. Oh, so that you know, this Canary copy .ISO have the new Flutter-based installer. Although I tried to use this new installer, it crashes every time.

Closing Notes

The LTS releases are conservative in new tech adaptation and other long term impacts. Many organizations and businesses opt for LTS for more than five years of support window and stability. Stability is more important than new technology when running thousands of machines critical to your company. So, that said, many new features or packages could not make it to the final release, but eventually, this release set the course for the next LTS. One step at a time.

So, what feature or package is interesting for you in Ubuntu 22.04? Let me know in the comment section below.
