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](https://access.redhat.com/support/policy/updates/errata).

## Architectures

* AMD/Intel 64-bit (x86\_64\_v3)

* ARM 64-bit (ARMv8.0-A)

* IBM Power (POWER9)

* IBM Z (z14)

These architecture build targeting a specific level of processor capabilities.

Targeting newer levels enables desirable optimizations,

but also sets the minimum hardware requirement.

You can check what levels your CPU supports by running `ld.so --help`.

A notable change in this release is that the AMD/Intel 64-bit build now targets the

[v3 microarchitecture level](https://developers.redhat.com/articles/2024/01/02/exploring-x86-64-v3-red-hat-enterprise-linux-10).

## 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.

These packages are maintained for the full lifecycle of the operating system.

### AppStream

Packages in the AppStream repository include additional user-space applications, runtime languages, and databases

to accomodate various workloads and use cases.

Many of these packages are maintained for the full lifecycle of the operating system,

but some have shorter independent lifecycles.

The specific lifecycle dates will be determined by the corresponding

[Application Stream](https://access.redhat.com/support/policy/updates/rhel-app-streams-life-cycle)

in RHEL 10.

Optional alternative versions of select software are expected to be added over time.

### CRB

Packages in the CRB repository are intended to accomodate development use cases.

## New features and enhancements

CentOS Stream 10 includes several notable new features and enhancements.

### Kernel

* Linux kernel 6.12

### Programming languages and compilers

* Python 3.12

* GCC 14

* Go 1.23

* Rust 1.82

* LLVM 19

* Ruby 3.3

* Node.js 22

* PHP 8.3

* OpenJDK 21

### Webservers

* Apache HTTP Server 2.4.62

* nginx 1.26

### Databases

* PostgreSQL 16

* MariaDB 10.11

* MySQL 8.4

* Valkey 7.2

### Desktop technologies

* GNOME 47

* Qt 6.7

### Software management

* DNF 4.20

* RPM 4.19

Earlier versions of CentOS Stream utilized a technology called modularity

to provide optional alternative versions of select software.

CentOS Stream 10 will instead use traditional non-modular RPM packages for this purpose.

## 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).

## More information

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](https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/10-beta/)

provides additional notes and guides which mostly apply to CentOS Stream as well.
