Canonical announced the latest LTS (long-term support) version of its operating system Ubuntu. Version 22.04 or Jammy Jellyfish is the 36th version in the history of the Linux release since 4.10 Warty Warthog in 1994 and is generally considered to have started the entire process.

The LTS version has been supported for five years, instead of bringing a lot of new features and hardware support, it tends to get a series of point versions that incorporate innovations from later non-LTS versions.

However, jelly jellyfish (which may use the British definition of "jam" to indicate luck, rather than literally recommending jelly to cover jellyfish, which may violate many very specific wildlife conservation laws) has brought about some changes. The desktop is mainly Gnome 42, but many of the earlier versions of applications and libraries are retained. Depending on the core application port of Gnome 42, Canonical decided to do more testing before releasing it to the universal desktop, but to keep the old version. However, you did get the shell desktop of Gnome 42, the latest version of the Nautilus file manager, and the updated screenshot tool.

Although the default orange scheme and sidebar are reminiscent of earlier versions of Debian-based releases, there are many visual changes. There is a light and shade mode, and if the default orange disagrees with you, you can choose your own accent color. Virtual desktops and application switches now flow horizontally instead of vertically, Wayland is now the default display server, and Xorg is still available to users using Nvidia GPU, who may encounter problems.

Next, there are more changes. Kernel 5.15 LTS,Jammy is the first operating system version designed to run well on Raspberry Pi 4 2GB, which was previously unpopular with the operating system because of its lack of RAM. As a result, it naturally works well on Pi 4 boards with more memory. "with Ubuntu 22.04 LTS, it supports the entire latest Raspberry Pi device portfolio for the first time, from the new Raspberry Pi Zero 2W to Raspberry Pi 4," said Eben Upton, CEO of Raspberry Pi Trading. "I'm glad to see that the certified Ubuntu desktop version includes support for 2GB Raspberry Pi 4, giving developers around the world access to the most affordable development desktop environment."
