The beta release of the distribution has been released Ubuntu April 22, "Jammy Jellyfish," after which a complete freeze of the package database was implemented, and the developers moved on to final testing and bug fixing. The release, which is categorized as a long-term support (LTS) release, for which updates are generated over a five-year period until 2027, is scheduled for April 21. Ready-to-use test images have been created for Ubuntu, Ubuntu Server, Lubuntu, Kubuntu, Ubuntu Mate, Ubuntu Budgie, Ubuntu Studio, Xubuntu и UbuntuKylin (China edition).
Major changes:
- The desktop has been updated to GNOME 42, which adds a global dark theme and optimizes GNOME Shell performance. The PrintScreen button now allows you to create a screencast or screenshot of a selected portion of the screen or a specific window. To maintain a consistent look and stability throughout the user environment, Ubuntu 22.04 retains versions of some applications from the GNOME 41 branch (mostly applications ported to GTK 4 and libadwaita in GNOME 42). For most configurations, a Wayland-based desktop session is enabled by default, but an option to fallback to the X server is available upon login.
- Offered 10 color options in dark and light styles. Icons on the desktop are moved to the lower right corner of the screen by default (this behavior can be changed in the appearance settings). In the Yaru theme, all buttons, sliders, widgets, and toggles use orange instead of eggplant. A similar replacement is made in the set of icons. Changed the color of the active window close button from orange to gray, and the color of slider handles from light gray to white.
- The Firefox browser is now only available in Snap format. The firefox and firefox-locale deb packages are replacements for stubs that install a Snap package with Firefox. For users of the deb package, there is a transparent process for migrating to snap by publishing an update that will install the snap package and transfer the current settings from the user's home directory.
- To increase security, the os-prober utility is disabled by default, which finds boot partitions of other OSes and adds them to the boot menu. It is recommended to use the UEFI bootloader to boot alternative operating systems. To return the automatic detection of third-party OSes in /etc/default/grub, you can change the GRUB_DISABLE_OS_PROBER setting and run the "sudo update-grub" command.
- Disabled access to NFS partitions using the UDP protocol (the kernel was compiled with the CONFIG_NFS_DISABLE_UDP_SUPPORT=y option).
- Core Linux Updated to release 5.15. Updated package versions: GCC 11.2, Python 3.10, Ruby 3.0, PHP 8.1, Perl 5.34, LibreOffice 7.3, BlueZ 5.63, CUPS 2.4, NetworkManager 1.36, Mesa 22, Poppler 22.02, PulseAudio 16, xdg-desktop-portal 1.14, PostgreSQL 14. Migrated to new branches of OpenLDAP 2.5 and BIND 9.18.
- By default, the nftables packet filter is enabled. To preserve backward compatibility, the iptables-nft package is available, which provides utilities with the same command line syntax as in 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. The "-s" option has been added to the scp utility to work over the SFTP protocol.
- In assemblies Ubuntu Server for IBM POWER systems (ppc64el) has dropped support for Power8 processors, builds are now built for Power9 CPUs ("--with-cpu=power9").

The core package includes new GNOME applications: Clock, Maps, and Weather. The panel indicator set has been updated. By removing proprietary NVIDIA drivers (now downloaded separately), eliminating duplicate icons, and removing old themes, the installation image size has been reduced to 2.8 GB (previously, it was 4.1 GB).
