Arch Linux has issued its monthly installation ISO for March 2026, incorporating updates from February's repositories. The snapshot includes a new Linux kernel, refreshed libraries, desktop environments, and security enhancements. It serves as installation media for new users without introducing specific distribution changes.
On March 1, 2026, Arch Linux announced the release of its updated installation ISO dated 2026.03.01. This monthly snapshot aggregates package updates pushed to the official repositories during February 2026, offering refreshed media for fresh installations rather than altering core distribution features.
The ISO features Linux kernel 6.18.13 LTS as the default, with version 6.12.74 LTS also accessible in the repositories. Core system libraries have been updated, including Glibc 2.43, GCC 15.2.1 across the compiler suite, systemd 259.2, and GNU Binutils 2.46.
Security improvements are evident in the inclusion of NSS 3.121, ca-certificates-mozilla 3.121, GnuTLS 3.8.12, and libgcrypt 1.12.1. Hardware compatibility benefits from linux-firmware 20260221 and amd-ucode 20260221 microcode updates.
Desktop environments receive attention as well. KDE Plasma 6.6.1 arrives with KDE Frameworks 6.23 and KDE Gear 25.12.2, providing refinements to the Plasma 6.6 series. GNOME 49.4 includes updates to GNOME Shell, Files, and essential applications. Additional options encompass Cinnamon 6.6.7, Budgie 10.10.1, COSMIC 1.0.8, and Hyprland 0.54, all available via repositories.
Popular applications are refreshed, such as Chromium 145 and Firefox 148 for browsing, and LibreOffice 26.2.1 for productivity. Container tools update to Docker 29.2.1, with the latest Podman stack as a daemonless alternative. Creative software like Blender 5.0.1 is also repository-ready.
Further base updates cover Python 3.14.3, iproute2 6.19, GNU Coreutils 9.10, and zstd 1.5.7. The ISO integrates Archinstall 3.0.15, a text-based guided installer to simplify setups.
Users can download the ISO from official Arch mirrors immediately. It targets new installations exclusively; existing systems should use the command 'sudo pacman -Syu' for updates.
