| guide | Canonical has announced the latest LTS (Long Term Support) release of Ubuntu, 22.04 (Jammy Jellyfish), which is the 36th release since 2004's 4.10 (Warty Warthog). |
Ubuntu 22.04 LTS will bring support for Ubuntu Desktop, Ubuntu Server, Ubuntu Cloud, and Ubuntu Core for 5 years, that is, until April 2027.
Some improvements in Ubuntu 22.04 LTS are as follows:
Linux kernel:
Ubuntu Desktop will automatically opt-in to the v5.17 kernel on the latest generation certified devices (linux-oem-22.04).
Ubuntu Desktop uses a rolling HWE kernel (linux-hwe-22.04) on all other generations of hardware. The rolling HWE kernel is based on the v5.15 kernel of the 22.04.0 and 22.04.1 releases.
Ubuntu Server defaults to the non-rolling LTS kernel v5.15 (linux-generic).
Ubuntu Cloud and devices work with partners to use optimized kernel v5.15+.
Nvidia driver:
Ubuntu 22.04 LTS adds linux-restricted-modules for Nvidia drivers on ARM64 in addition to the existing x86_64. ARM64 users can now install and configure NVIDIA drivers from the Ubuntu Archive using the ubuntu-drivers tool.
Toolchain upgrade:
GCC is updated to version 11.2.0, binutils is updated to 2.38, and glibc is updated to 2.35.
Python was upgraded to 3.10.4, and Perl was upgraded to 5.34.0.
LLVM now defaults to version 14, golang defaults to version 1.18.x, and rustc defaults to version 1.58.
In addition to OpenJDK 11, OpenJDK 18 is now provided (but not for package builds).
Ruby updated from v2.7.4 to v3.0.
OpenSSL 3.0：
The OpenSSL library has been upgraded to the new 3.0 version, with many legacy algorithms disabled by default. Certificates that use SHA1 or MD5 as hash algorithms are now invalid at the default security level.
Ubuntu Desktop：
Ubuntu now offers 10 color options, each available in dark and light styles.
Firefox is now only available in Ubuntu as a snapshot, maintained directly by Mozilla, which means getting the latest Firefox version faster.
Desktop icons appear by default in the bottom right corner, but this can be changed with a new setting added to the Appearance panel of the Settings app.
New settings that control the appearance and behavior of the Dock.
Dock device and file manager integration has been improved.
GNOME：
GNOME uses GNOME 41 and GNOME 42, mainly to avoid libadwaita.
Support for new cross-desktop dark style preferences.
GNOME Shell and mutter bring many performance improvements.
Support for hardware with privacy screens.
RDP can now be used for remote desktop sharing.
