Red Hat has published FAQ about the upcoming changes in CentOS.
CentOS Stream Updates FAQ
Following up on our September 2019 announcement of the creation of CentOS Stream, we are now announcing that our sponsorship of CentOS Linux will be changing in December 2021. We have worked with the CentOS Project Governing Board as part of this change.
CentOS Stream is an upstream development platform designed for CentOS community members, Red Hat partners, ecosystem developers, and many other groups to more quickly and easily see what’s coming in the next version of Red Hat Enterprise Linux (RHEL) and to help shape these capabilities. Since its introduction in 2019, we’ve seen great enthusiasm from partners and contributors around CentOS Stream and the continuous stream of innovation that the project provides.
On December 8, 2020, we are announcing this timeline for CentOS Linux and CentOS Stream sponsorship by Red Hat:
There will not be a CentOS Linux 9.
Updates for the CentOS Linux 8 distribution continue until December 31, 2021.
Updates for the CentOS Linux 7 distribution continue as before until June 30, 2024.
Updates for the CentOS Linux 6 distribution ended November 30, 2020.
CentOS Stream 9 will launch in Q2 2021 as part of the RHEL 9 development process.
Updates for the CentOS Stream 8 distribution continue through the full RHEL support phase.
