Welcome to CentOS Stream 10 "Coughlan", the latest version of the CentOS Project distribution.
CentOS Stream defines Enterprise Linux. It is a Linux distribution built by Red Hat Enterprise Linux (RHEL) engineers, and is used as the major version branch that RHEL minor versions are created from. It has roughly a five year lifecycle and will be maintained until 2030. The exact date will be contingent on the end of the Full Support phase of RHEL 10.
CentOS Stream 10 uses the Linux 6.12 kernel, which provides support for the following architectures.
CentOS Stream 10 is distributed through two main DNF repositories, BaseOS and AppStream. The CRB repository is also available, but is disabled by default.
Packages in the BaseOS repository are intended to provide the core set of operating system functionality.
Packages in the AppStream repository include additional user-space applications, runtime languages, and databases to accomodate various workloads and use cases.
Packages in the CRB repository are intended to accomodate development use cases.
CentOS Stream 10 includes several notable new features and enhancements.
CentOS Stream 10 does not include some packages that were previously included in CentOS Stream 9.
Xorg server (xorg-x11-server-Xorg) is no longer included.
Wayland is the default display stack,
with Xwayland (xorg-x11-server-Xwayland) available as a compatibility layer for legacy X11 applications.
You can read more about this transition in the blog post
Red Hat Enterprise Linux 10 plans for Wayland and Xorg server.
Most graphical desktop applications have been removed. This includes:
RHEL is transitioning to providing desktop applications via Flatpak. CentOS users who want these applications are encouraged to install them from Flathub or request them in EPEL.
Redis has been replaced with Valkey, a Redis fork.
At this time, CentOS Stream 10 does not work with secureboot enabled. This is currently blocked on a shim review.
This page is intended as an overview of the basic properties of CentOS Stream 10, but it is not an exhaustive list of all changes and topics. The RHEL 10 Beta documentation provides additional notes and guides which mostly apply to CentOS Stream as well.
