The newest LTS (long-term support) version of Ubuntu has been released by Canonical. 22.04, or Jammy Jellyfish, is the 36th Linux distribution to be released since 4.10 Warty Warthog in 1994, which is usually regarded as the release that started it all.
Instead of a flurry of new features and hardware support, LTS releases have a succession of point releases via which following non-LTS releases’ innovations are integrated.
Some modifications are brought about by the Jammy Jellyfish (presumably adopting the UK word of “jammy” to signify lucky, rather than actually advising coating a jellyfish in jam), though. Gnome 42 dominates the desktop, but older programs and libraries can still be found. As a result, Canonical chose to keep the older versions instead of releasing Gnome 42’s ports of essential programs until they had been thoroughly tested. Gnome 42’s shell desktop, the newest version of Nautilus file manager, and the improved snapshot tool are included, though.
Even yet, despite the same orange color scheme and side-dock, there are a lot of aesthetic updates to this Debian-based distro. If you don’t like the orange accent color, you may switch to a darker setting and change the color of the text. Wayland is now the default display server, with Xorg remaining accessible for users with Nvidia GPUs who may run into issues. Virtual desktops and the app switcher now flow horizontally rather than vertically.
There are many more changes hidden beneath the surface. Because of the Raspberry Pi 4 2GB’s lack of RAM, prior versions of the OS didn’t like it very much. The kernel is now at version 5.15 LTS and Jammy is the first version of the OS engineered to function well on that device. As a result, Pi 4 boards with additional RAM should have no issues running it. According to CEO of Raspberry Pi Trading, Eben Upton, Ubuntu 22.04 LTS includes compatibility for all latest devices from the Raspberry Pi Zero 2W to the Raspberry Pi 4. For developers across the world, it’s wonderful to see a certified Ubuntu Desktop version that includes support for the 2GB Raspberry Pi 4, making the most cheap development desktop environment available to everyone.
Ubuntu is now the only Linux distribution that supports Azure Confidential VMs, which provide anonymity not just between various cloud customers, but also between customers and the cloud itself. Encryption keys managed and maintained by the customer are used in Ubuntu and Azure Managed HSM to secure customer code and data when in use, transit, or storage at the hardware level as well as during boot and full-disk encryption.
In addition, the new version of OpenSSL v3 is more secure, as well as the inclusion of Active Directory compatibility in the installer and the ability to easily comply with standards such as PCI-DSS, HIPAA, and FedRAMP.
