OzLabs is a collection of Australian free-software developers that was, for most of its history, associated with IBM. Members of OzLabs have included Hugh Blemings, Michael Ellerman, Ben Herrenschmidt, Greg Lehey, Paul Mackerras, Martin Pool, Stephen Rothwell, Rusty Russell, and Andrew Tridgell, among others. The OzLabs "about" page notes that, as of January 2026, the last remaining OzLabs members have departed IBM. "This brought to a close the Ozlabs association with IBM". Thus ends a quarter-century of development history.

4MLinux is a miniature Linux distribution focusing on four capabilities: maintenance (as a system rescue live CD), multimedia (for playing video DVDs and other multimedia files), miniserver (using the inetd daemon), and mystery (providing several small Linux games). The distribution includes support for booting on UEFI-enabled machines.

PostgreSQL contributor Robert Haas has published a blog post that breaks down code contributions to PostgreSQL in 2025.

I calculate that, in 2025, there were 266 people who were the principal author of at least one PostgreSQL commit. 66% of the new lines of code where contributed by one of 26 people, and 90% of the lines of new code were contributed by one of 67 people.

Contributions to the project seem to be on the upswing; in his analysis of development in 2024, there were 229 people who were the primary authors of a commit, and 66% of new lines of code were contributed by one of 18 people. The raw data is also available.

The io_uring subsystem is more than an asynchronous I/O interface for Linux; it is, for all practical purposes, an independent system-call API. It has enabled high-performance applications, but it also brings challenges for code built around classic, Unix-style system calls. For example, the seccomp() sandboxing mechanism does not work with it, causing applications using seccomp() to disable io_uring outright. Io_uring maintainer Jens Axboe is seeking to improve that situation with a rapidly evolving patch series adding a new restrictive mechanism to that subsystem.

Version 11.0 of the Wine Windows compatibility layer is out. "This release represents a year of development effort, around 6,300 individual changes, and more than 600 bug fixes." The most notable changes in this release are support for the NTSync Linux kernel module (when available), and the completion of the Windows 32-bit on Windows 64-bit (WoW64) architecture that was announced as experimental in Wine 9.0.

Greg Kroah-Hartman has released the 5.15.198, and 5.10.248 stable kernels. As usual, each contains important fixes throughout the tree; users are advised to upgrade.

deepin (formerly, Deepin, Linux Deepin, Hiweed GNU/Linux) is a Debian-based distribution (it was Ubuntu-based until version 15 released in late 2015) that aims to provide an elegant, user-friendly and reliable operating system. It does not only include the best the open source world has to offer, but it has also created its own desktop environment called DDE or Deepin Desktop Environment which is based on the Qt 5 toolkit. Deepin focuses much of its attention on intuitive design. Its home-grown applications, like Deepin Software Centre, DMusic and DPlayer are tailored to the average user. Being easy to install and use, deepin can be a good Windows alternative for office and home use.

MX Linux, a desktop-oriented Linux distribution based on Debian's "Stable" branch, is a cooperative venture between the antiX and former MEPIS Linux communities. Using Xfce as the default desktop (with separate KDE Plasma and Fluxbox editions also available), it is a mid-weight operating system designed to combine an elegant and efficient desktop with simple configuration, high stability, solid performance and medium-sized footprint.

HackerOS is a live Linux distribution based on Debian's "Testing" branch and designed for regular users, gamers and cybersecurity enthusiasts. Some of its features include an optimised XanMod Linux kernel for faster boot times and reduced resource usage, out-of-the-box support for NVIDIA graphics cards, and a collection of cybersecurity tools, such as enhanced firewalls and intrusion detection software. The distribution uses the KDE Plasma desktop.

Linus has released 6.19-rc6 for testing. "So we finally ended up with a slightly bigger rc than usual for this stage in the release cycle, but it's not _that_ big, and things still seem quite stable and civilized."

Shanios is an immutable desktop Linux distribution based on Arch Linux. It provides optimised builds of the GNOME and KDE Plasma desktop environments. Like most immutable Linux systems, Shanios features rollbacks for instant system recovery, atomic updates through a custom deployment tool called shani-deploy, and Flatpak integration. The distribution's other main features include a blue-green deployment strategy using Btrfs subvolumes, preservation of system integrity with a read-only root partition, and enhanced security through AppArmor profiles, firewalld configurations, and full-disk encryption.

ELEGANCE is a French, general-purpose desktop Linux distribution based on Manjaro Linux. It uses the Cinnamon desktop environment. The distribution offers a rich variety of software for everyday use, including for office work (LibreOffice, Calibre), entertainment (VLC, Rhythmbox, Kodi), graphics (Gimp, Krita), gaming (Steam), audio recording (Audacity, OBS Studio), audio mixing and editing (Ardour, LMMS, Kdenlive), and design (LeoCAD FreeCAD et KiCAD). ELAGANCE is sponsored by Tux N Mix, an organisation created by a group of Linux enthusiasts in 2019.

Synex is a GNU/Linux distribution based on Debian's "Stable" branch, developed with the official Debian Live Build tool. It offers four separate desktop options with GNOME, LXDE, KDE Plasma and Xfce, all of which are composed of a rather frugal set of applications in its default state, without any development tools or offices suites. Some of the distribution's main features include Calamares installer with support for both BIOS and UEFI, CUPS integration for printing and network support, out-of-the box support for Flatpak applications, official NVIDIA driver installation assistant with support for both X11 and Wayland, and additional repositories containing Microsoft Edge, OnlyOffice and Zabbix.

Greg Kroah-Hartman has released the 6.18.6, 6.12.66, 6.6.121, and 6.1.161 stable kernels. As usual, each has important fixes throughout the tree; users are advised to upgrade.
