CentOS Stream 10 Overview

Released December 2024. Lifecycle until ~2030 (RHEL 10 Full Support). Codename "Coughlan".

Architectures

  • AMD/Intel 64-bit: now x86_64_v3 (requires AVX2, BMI2, FMA — Haswell/Excavator or newer)
  • ARM 64-bit (ARMv8.0-A)
  • IBM Power (POWER9)
  • IBM Z (z14)

Check CPU support: ld.so --help

Xorg Server Removed

xorg-x11-server-Xorg no longer included. Wayland is the only display server. xorg-x11-server-Xwayland available for legacy X11 application compatibility.

Desktop Applications Removed

GIMP, LibreOffice, and Inkscape removed from repositories. Install via Flatpak from Flathub or request in EPEL.

Redis Replaced by Valkey

Redis removed due to license change (BSD-3 -> RSALv2/SSPLv1). Valkey 7.2 is the API-compatible, BSD-licensed replacement.

Modularity Removed

No longer uses modularity system for alternative package versions. Traditional non-modular RPM packages used instead. Alternative versions expected to be added over time as standard AppStream packages.

Repositories

Same structure: BaseOS, AppStream, CRB (disabled by default). DNF 4.20, RPM 4.19.
