AerynOS closes 2025 with major package upgrades, infrastructure improvements, and a refreshed 2025.12 Alpha ISO.

AerynOS, an atomic-update-based (not to be confused with immutability) still-in-development Linux distro currently in alpha, has shared its latest project update for December 2025.

The distro released its latest Alpha ISO, version 2025.12. This GNOME-based live environment includes Linux kernel 6.17.10 and uses the Lichen installer, which still requires a network connection to fetch pkgsets during installation.

The update brings COSMIC Beta9, GNOME 49.2, KDE Plasma 6.5.4, KDE Frameworks 6.20, and KDE Gear 25.08.2, alongside updates to core tools such as the Bash shell, Mesa with Vulkan anti-lag, LLVM, Buildah, Docker, OpenVPN, SCX schedulers, Vim, Wine, Zed, and more.
