Ubuntu 22.04 LTS "Jammy Jellyfish" has already been released and these are its news

Few days ago the release of the new version of Ubuntu 22.04 LTS "Jammy Jellyfish" was announced which is categorized as a long-term support (LTS) version with updates for 5 years, which in this case will be until April 2027.

Of the main changes that have been introduced in this new version of Ubuntu 22.04 LTS "Jammy Jellyfish", the GNOME 42 desktop environment update, in which settings for the dark interface design common to the entire environment have been added and GNOME Shell performance has been optimized.

When you press the PrintScreen button, you can create a screencast or screenshot of a selected part of the screen or a separate window. To preserve the integrity of the design and the stability of the user environment in Ubuntu 22.04, some applications have been left behind in the GNOME 41 branch (mainly we are talking about applications translated in GNOME 42 to GTK 4 and libadwaita).

most configurations default are a desktop session based on the Wayland protocol, but they do provide an option to switch back to using an X server when logging in. The use of the X server is also left by default for systems with NVIDIA proprietary drivers.

10 color options are offered in dark and light styles. Desktop icons have been moved to the bottom right corner of the screen by default (this behavior can be changed in appearance settings). In the Yaru theme, all buttons, sliders, widgets, and toggles use orange instead of aubergine. A similar replacement is done on the icon set. Changed the color of the active window's close button from orange to gray and the color of the sliders from light gray to white.

For the base part of the system, this new version arrives with Linux kernel 5.15, but Ubuntu Desktop on some tested devices (linux-oem-22.04) will provide a 5.17 kernel. Additionally, for the x86_64 and ARM64 architectures, a beta version of a kernel package is proposed for testing, which includes PREEMPT_RT patches and is intended for use in real-time systems.

The system administrator systemd has been updated to version 249 and in which for an early response to memory shortage, the systemd-oomd mechanism is used by default, which is based on the PSI (Pressure Stall Information) kernel subsystem, which allows user-space analysis of wait time information for various resources (CPU, memory, I/O) to accurately assess the level of system load and the nature of the slowdown. You can use the oomctl utility to check the status of OOMD.

In addition, it should be noted that in this new version set formation is provided of facilities operating in live mode for RISC-V architecture, which also Ubuntu 22.04 is the first LTS release with official builds for Raspberry Pi boards.

On the part of NVIDIA proprietary drivers added to ARM64 architecture builds in the Linux restricted module set (previously shipped only for x86_64 systems). To install and configure NVIDIA drivers, you can use the standard ubuntu-drivers utility.

Another change that stands out in this new version of Ubuntu 22.04 LTS is in the browser Firefox that is now only available in Snap format. The firefox and firefox-locale deb packages are replacements for the stubs that install a Snap package with Firefox. For users of the deb package, there is a transparent process to migrate to snap by publishing an update that will install the snap package and transfer the current configuration from the user's home directory.

By default, the packet filter nftables is enabled. For backward compatibility, the iptables-nft package is available, which provides utilities with the same command line syntax as iptables, but translates the resulting rules into nf_tables bytecode.
OpenSSH does not support digital signatures based on RSA keys with a SHA-1 hash ("ssh-rsa") by default. Added "-s" option to scp utility to work over SFTP protocol.
