In July 2009, it was reported in an open letter on the CentOS Project web site that CentOS's founder, Lance Davis, had disappeared in 2008. Tao users migrated to the CentOS release via yum update. In June 2006, David Parsley, the primary developer of Tao Linux (another RHEL clone), announced the retirement of Tao Linux and its rolling into CentOS development. Infiscale described its GravityOS as " the small footprint of Caos", indicating a certain level of influence from the discontinued distribution. History ĬentOS originated as a build of CAOS Linux, an RPM-based Linux distribution started by Gregory Kurtzer in 2002. ĬentOS Linux was discontinued at the end of 2021 in favor of CentOS Stream, a distribution positioned upstream of RHEL. In March 2021, Cloud Linux (makers of CloudLinux OS) released a new RHEL derivative called AlmaLinux. In response, CentOS founder Gregory Kurtzer created the Rocky Linux project as a successor to the original mission of CentOS. In December 2020, Red Hat unilaterally terminated CentOS development. CentOS 8 was released on 24 September 2019. As of December 2015, AltArch releases of CentOS 7 are available for the IA-32 architecture, Power ISA, and for the ARMv7hl and AArch64 variants of the ARM architecture. Since version 8, CentOS officially supports the x86-64, ARM64, and POWER8 architectures, and releases up to version 6 also supported the IA-32 architecture. The first CentOS release in May 2004, numbered as CentOS version 2, was forked from RHEL version 2.1AS. In January 2014, CentOS announced the official joining with Red Hat while staying independent from RHEL, under a new CentOS governing board. rpm (binaries format)ĬentOS ( / ˈ s ɛ n t ɒ s/, from Community Enterprise Operating System also known as CentOS Linux) is a discontinued Linux distribution that provided a free and open-source community-supported computing platform, functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). Servers, desktop computers, workstations, supercomputersĭnf (command line) PackageKit (graphical). Since two years is not long enough for the manufacturers to bring support for their hardware and software features, you’ll often find some LTS kernels to be supported for six years.CentOS Stream 9 in the Workstation configuration, showing its desktop environment, GNOME 40. This often happens for the Android projects. The agreement is done based on the necessity and the players involved. The maintainer of a LTS kernel may agree to maintain a certain LTS kernel for longer than the usual period of two years. But again, there is no set rules here as well. Usually, there is one LTS kernel release every year, usually the last release of the year and it is supported for at least two years. There is no set release schedule for LTS kernel as well. The LTS Kernel: How long is it supported? There are LTS (long term support) kernel versions as well and they are supported for a much longer period than just 3 months. This is applicable to the normal stable kernel versions only. Users and contributors are asked to switch to the newly released stable version. The end of support is announced by the maintainer of that particular stable kernel version in the Linux kernel mailing list. Like the release, there is no fixed dates and schedule for how long a kernel version will be supported.Ī regular stable kernel release is usually supported for two and a half months to three months, depending on the release of the next stable kernel release.įor example, stable kernel 5.14 would reach end of life a couple of weeks after the release of stable kernel 5.15. While X.Y is (often) released by Linux creator Linus Torvalds, the responsibility to maintain the stable X.Y kernel, merge bug fixes and release X.Y.Z versions is handled by a kernel developer. These small releases add one more point to the stable kernel to make it like X.Y.Z. The stable release gets further smaller releases to accommodate bug fixes. The release is declared ‘stable’ and is usually numbered in the format of X.Y.īut this is not the end of X.Y development. This typically happens every 2 to 3 months. That’s what the kernel maintainer team targets but there is no set deadline that the new version has to be released exactly 8 weeks from the previous release.Ī new kernel version is released (often) by Linus Torvalds when it is ready. What it means is that you’ll often see a new kernel version release every two to three months. The long answer is that it’s not a hard and fast rule. The short answer is that a new kernel version is release every two to three months.
