4MLinux 52.2 STABLE Released, Adds Linux 6.18.55 Kernel
On October 31, 2026, the one-person Polish distro pushed version 52.2 STABLE into its main channel. It's a point release, which is a polite way of saying "kernel bump." The new base moves to Linux 6.18.55, sitting on the 6.18 LTS line that's supported through December 2027. That's the release. That's really the whole release.
4MLinux is the kind of distro that makes you double-check its size before believing it. A full Linux desktop, assembled almost entirely from source, with no fork off Debian, Fedora, Arch, or anything else. No apt. No dpkg. No RPM. Just tar.xz packages and a hand-rolled update tool.
The name comes from four pillars. Maintenance is a live rescue tool with GParted, TestDisk, and ddrescue. Multimedia bundles GIMP, Audacious, VLC, and mpv. Miniserver offers a 64-bit LAMP stack under the 4MServer edition. Mystery is a grab bag of retro games, with a Game Edition that runs native 90s titles like Doom and Hexen.
The rest of the stack is deliberately old-school. JWM handles windows, feh does wallpapers, PCManFM does files, and Conky sits in the corner as a preinstalled system monitor. Init comes from BusyBox. There's no systemd in sight, and LILO boots it up fast. It boots in seconds.
The footprint stays tiny. You're looking at roughly 300 MB of RAM when installed to disk, around 2 GB for a live session. The full ISO is about 2.3 GB, 4MLinux-52.2-64bit.iso, and the official SourceForge upload landed on 2026-10-31 at 14:20:34 UTC.
Where 52.2 Fits
The 52.x line didn't appear out of nowhere. 52.0, shipped July 31, 2026, was the major release that set the current direction: Linux 6.18 LTS (up from 6.12), Mesa 26.0 graphics, Ultra HDR image support via libultrahdr, and new default apps including ksh and audioconvert. 52.1 arrived September 8 as a security-focused point release, bumping the kernel to 6.18.43 and patching AMD's SRSO / Safe-RET interrupt-injection hole. 52.2 threads the same line forward to 6.18.55.
Looking past it, Core BETA for 53.0 dropped in August 2026, hinting at a big toolchain jump next time around: GCC 16.x (from 15.x), glibc 2.44 (from 2.43), and BusyBox 1.38. BIOS and UEFI both stay supported on x86_64. 32-bit support was quietly dropped way back in 31.0, December 2019.
It's not a distro for everyone. But it's a good one for a specific and growing slice of users: anyone still running hardware that mainstream distros have stopped caring about. Building from source rather than repackaging upstream shows real packaging muscle, and it's exactly what keeps the dependency chain short enough for old machines to run. A ~2 GB rescue image getting timely hardening means "minimal" doesn't have to mean "insecure."
If you want to try it, grab 4MLinux-52.2-64bit.iso (~2.3 GB) from the SourceForge project page. Existing 52.x users should just run zk update rather than reinstall. Server needs are covered by the 4MServer edition, which adds a ready-to-use LAMP HTTP/FTP setup. Downloads are free, with optional PayPal donations,
