Ubuntu 22.04 LTS Wallpaper "Jammy Jellyfish"
After six months of the last update, it became known A few days ago, the release of the fourth update of the LTS version of "Ubuntu 22.04.4 LTS" and arrives with a series of changes designed to improve hardware support, update the Linux kernel and graphics stack, as well as fix bugs in the installer and bootloader.
This package also includes updates for hundreds of related packages, addressing the elimination of vulnerabilities and issues that affect system stability.
What's new in Ubuntu 22.04.4 LTS?
In this new update that has been presented for Ubuntu 22.04.4 LTS, as in previous versions, the improvements implemented offer us an updated kernel and graphics stack, since for example this update includes several improvements supported from Ubuntu 23.10. And in the case of the heart of the system, we can find that packages are offered with version 6.5 of the Linux kernel (the base kernel in the release of Ubuntu 22.04 was version 5.15).
On the graphics stack side, Ubuntu 22.04.4 LTS includes the updated components of the Mesa 23.1.7 graphics stack, which were tested in Ubuntu 23.10 version. This desktop version has the new versions of video drivers for Intel, AMD and NVIDIA chips andsupport for AMD GPU to Rusticl driver, which features an implementation of the OpenCL 3.0 specification written in Rust. Additionally, improvements have been implemented to the Vulkan ANV (Intel) and RADV (AMD) drivers, which now offer initial support for the Vulkan Video extension. This extension defines capabilities for hardware-accelerated video decoding, meaning users can expect improved performance and a smoother video viewing experience on Vulkan.
Other changes that stand out are that Updated versions of some important packages are includeds, such as dpdk 21.11.4, cloud-init 23.3.3 and openvswitch 2.17.8 and added a build for servers based on ARM architecture, in which the Linux kernel is compiled with support for 64 KB memory pages.
In desktop versions (Ubuntu Desktop), the new kernel and graphics stack are offered by default. For server systems (Ubuntu Server), the new kernel is added as an option in the installer. Importantly, it only makes sense to use new builds for new installations, as previously installed systems can receive all the changes present in Ubuntu 22.04.4 through the standard update installation system.
In addition, it is worth mentioning that it is important to keep in mind that the delivery of new versions of the kernel and the graphics stack uses a continuous update support model. This means that supported kernels and drivers will only be supported until the next corrective update to the Ubuntu LTS branch is released. Therefore, the Linux 6.5 kernel proposed in the current release will be supported until the release of Ubuntu 22.04.5, at which point the Ubuntu 24.04 kernel will be offered (while the initially shipped base 5.15 kernel will be supported during the release cycle). five-year maintenance).
