Canonical today released Ubuntu 22.04 LTS for download as the latest version of its popular Linux-based operating system for personal computers, servers, and cloud computing.

Dubbed by Canonical the “Jammy Jellyfish”, Ubuntu 22.04 LTS has been in development for six months and is an upgrade to the Ubuntu 21.10 (Playful Indri) as well as the long term support release of Ubuntu 20.04 LTS (Focal Fossa).

Ubuntu 22.04 LTS comes with the latest Gnome 42 desktop environment with the triple buffering fix included, but it still uses apps from the GNOME 41 stack due to compatibility issues between the GTK4 apps included in the upstream release and Ubuntu’s Yaru theme. Applications that have not been ported to GTK4 come from the GNOME 42 stack, such as the Nautilus file manager (Files).

Ubuntu 22.04 LTS retains the same look and feel used since 2004 with the Ubuntu 11.04 “Natty Narwhal” release. However, there are some minor design changes, such as the fact that the Home and Trash desktop icons are now displayed by default in the lower right corner.

Additionally, there are new settings to control the appearance and behavior of the Dock, a system-wide dark style for all apps and dialogs, better Dock device and file manager integration, as well as than 10 accent color choices for dark and light styles from the default Yaru theme, which now mimics the look and feel of GTK4 apps.

Another great feature of the Ubuntu 22.04 LTS release is long term support. Linux 5.15 LTS kernel series, which brings an all-new implementation of the NTFS file system to allow you to read and write data to these disks without depending on a driver or third-party software. Linux kernel 5.15 LTS will be supported until at least October 2023 with security and bugfix updates.

Besides that, Jammy Jellyfish brings RDP support to share your remote desktop with better security, privacy and performance, Wayland as default session for most systems that don’t have NVIDIA graphics card, there has hardware support with privacy screen support, UDP is now disabled by default for NFS mounts, and a new logo appears on the splash screen and About page Settings app.

Under the hood there is an updated toolchain featuring some of the latest and greatest GNU/Linux technologies including but not limited to GCC 11.2, GNU C Library 2.35, GNU Binutils 2.38, systemd 249.11 , Python 3.10.4, Perl 5.34, Ruby 3.0, Golang 1.18, Mesa 22OpenSSL 3.0, LLVM 14, BlueZ 5.63, PulseAudio 16, OpenJDK 11, xdg-desktop-portal 1.14, Network Manager 1.36BlueZ 5.63, CUPS 2.4, rustc 1.58 and Poppler 22.02.
