title: CentOS Stream 10 Release Notes
---
## Introduction
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.
## Architectures
CentOS Stream 10 uses the Linux 6.12 kernel,
which provides support for the following architectures.
* x86\_64 (v3)
* aarch64
* ppc64le (power9)
* s390x (z14)
## Repositories
CentOS Stream 10 is distributed through two main DNF repositories,
BaseOS and AppStream.
The CRB repository is also available, but is disabled by default.
### BaseOS
Packages in the BaseOS repository are intended to provide the core set of operating system functionality.
### AppStream
Packages in the AppStream repository include additional user-space applications, runtime languages, and databases
to accomodate various workloads and use cases.
### CRB
Packages in the CRB repository are intended to accomodate development use cases.

## Removed functionality
CentOS Stream 10 does not include some packages that were previously included in CentOS Stream 9.
### Xorg server
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](https://www.redhat.com/en/blog/rhel-10-plans-wayland-and-xorg-server).
### Desktop applications
Most graphical desktop applications have been removed.
This includes:
* Firefox
* GIMP
* LibreOffice
* Inkscape
* Thunderbird
RHEL is transitioning to providing desktop applications via Flatpak.
CentOS users who want these applications are encouraged to install them from
[Flathub](https://flathub.org) or
[request them in EPEL](https://docs.fedoraproject.org/en-US/epel/epel-package-request/).
### Redis
Redis has been replaced with Valkey, a Redis fork.
## Known issues
### Secureboot
At this time, CentOS Stream 10 does not work with secureboot enabled.
This is currently blocked on [a shim review](https://github.com/rhboot/shim-review/issues/454).
