The CentOS Project has officially unveiled CentOS Stream 10, codenamed “Coughlan,” as the latest iteration of the Red Hat-backed Linux distribution. This release marks a significant step forward in the evolution of CentOS Stream, which serves as the upstream development platform for Red Hat Enterprise Linux (RHEL). Built by RHEL engineers, CentOS Stream 10 introduces several major enhancements and updates that pave the way for the future of enterprise Linux.

Key Features and Updates in CentOS Stream 10

1. Linux Kernel 6.12 LTS
CentOS Stream 10 runs on the robust Linux kernel 6.12 LTS, delivering improved stability, performance, and hardware support. As a result, this kernel ensures that the operating system is fully equipped to handle modern workloads efficiently.

2. Wayland Becomes the Default Display Stack
Notably, this release drops support for XOrg Server and adopts Wayland as the default display stack. Furthermore, Xwayland serves as a compatibility layer to ensure that legacy X11 applications continue functioning seamlessly. This change aligns CentOS Stream with the industry trend toward Wayland, offering better security and performance.

3. Introduction of Valkey 7.2
Another highlight is Valkey (v7.2), which replaces Redis as the default caching solution. This shift reflects a broader move towards adopting tools optimized for performance and scalability in enterprise environments.

4. GNOME 47 “Denver” Desktop Environment
The inclusion of GNOME 47 as the default desktop environment brings an updated user interface, new features, and enhanced performance. Thus, this release is ideal for users who rely on a graphical interface for managing their systems.

5. Updated Core Components
CentOS Stream 10 also features an impressive range of updated software packages, including:

• GCC 14
• LLVM/Clang 19
• Python 3.12
• Rust 1.82
• Ruby 3.3
• Go 1.23
• Node.js 22
• PHP 8.3
• MySQL 8.4
• PostgreSQL 16
  These updates ensure that CentOS Stream 10 provides developers with the latest tools and frameworks required for modern application development.

What’s New for Developers and Admins

DNF 4.20 and RPM 4.19
With DNF and RPM updated to their latest versions, system administrators benefit from improved performance and easier package management. Therefore, tasks like package installation and dependency management become more streamlined than ever before.

Targeting v3 Microarchitecture
CentOS Stream 10 also introduces support for AMD/Intel 64-bit v3 microarchitecture, boosting performance on modern hardware. However, this shift may limit compatibility with older systems, encouraging users to upgrade their infrastructure proactively.

Support for Flatpak Apps
In line with the industry’s emphasis on modular application management, most graphical desktop applications are now transitioned to Flatpak. Consequently, users benefit from better sandboxing and enhanced security for desktop apps.

Optional Non-Modular RPM Packages
In addition, the introduction of non-modular RPM packages offers greater flexibility. Developers can now access alternative versions of select software, which is especially useful for those needing different versions of specific libraries or tools.
