Once CentOS 7.7 was released resources moved back to CentOS 8.0. On 24 September 2019 CentOS officially released CentOS version 8.0. Since CentOS was discontinued at the end of 2021, its final release was version 8.5 (2021-11-16). In contrast, its RHEL counterpart continued to version 8.10 (as of 2024-09).
This article documents the version history of the Linux kernel. Each major version – identified by the first two numbers of a release version – is designated one of the following levels of support: Supported until next stable version; Long-term support (LTS); maintained for a few years [1]
CentOS Stream 9 was released on 3 December 2021, [9] with support of IBM Z architecture. In 2023, Red Hat announced that CentOS 7 and CentOS Stream 8 will be discontinued in 2024 in order to focus on Red Hat Enterprise Linux development. CentOS Stream 9 was given as one possible migration path. [10] CentOS Stream 10 was released on 12 December ...
On December 8, 2020, Red Hat announced that development of CentOS, a free-of-cost downstream fork of the commercial Red Hat Enterprise Linux (RHEL), would be discontinued and its official support would be cut short to focus on CentOS Stream, a stable LTS release without minor releases officially used by Red Hat to preview what is intended for inclusion in updates to RHEL.
A kernel is a component of a computer operating system. [1] A comparison of system kernels can provide insight into the design and architectural choices made by the developers of particular operating systems.
Rebootless updates can even be applied to the kernel by using live patching technologies such as Ksplice, kpatch and kGraft. Minimalistic foundations for live kernel patching were merged into the Linux kernel mainline in kernel version 4.0, which was released on 12 April 2015.
kpatch is a feature of the Linux kernel that implements live patching of a running kernel, which allows kernel patches to be applied while the kernel is still running. By avoiding the need for rebooting the system with a new kernel that contains the desired patches, kpatch aims to maximize the system uptime and availability.
The patch is compiled as usual, but the generated code has additional information about all changed code pieces caused by original source code modification and information on to how to apply these code pieces. The resulting code modifications are safely applied to the running kernel. A special KernelCare kernel module applies the patches. It ...
