In preparing for the GNOME 50 Alpha release, the "50.alpha" tags just occurred for the Mutter compositor and GNOME Shell. Most notable with GNOME Mutter 50 Alpha is the X11 back-end indeed being removed to focus exclusively on the Wayland session.

A Linux scheduler patch queued up into a TIP branch this past week further restrict is the preemption modes that will be advertised. With it hitting the "sched/core" branch, it will likely be submitted for the upcoming Linux 7.0 (or alternatively, what could be known as Linux 6.20 instead).

While Intel has been upstreaming various Panther Lake firmware bits to linux-firmware.git for pairing with their open-source kernel drivers ahead of Core Ultra Series 3 laptops shipping, one piece of the puzzle only published today is the GSC firmware for the Panther Lake graphics.

The Intel Compute Runtime 26.01.36711.4 was published today as their first release of 2026 for this open-source GPU compute stack providing Level Zero and OpenCL support across their range of graphics hardware going back to Tiger Lake. Notable with this new Compute Runtime release is having now production-ready Panther Lake support while also introducing early support for next-generation hardware.

Michel Dänzer of Red Hat has kicked off 2026 xorg-server activity with landing a patch series enhancing the Resize and Rotate (RandR) extension support under XWayland for improving mode handling by X11 clients.

Tomeu Vizoso as the open-source developer behind the "Rocket" driver for reverse-engineered Rockchip NPU support, Teflon as a Mesa framework for TensorFlow Lite and NPU uses, and various Etnaviv driver work, has announced his newest creation: Thames.

The open-source ZLUDA project for bringing CUDA to non-NVIDIA hardware that can run unmodified is out with a new progress report. ZLUDA had a productive fourth quarter with now enjoying better Microsoft Windows support, full support for running Llama.cpp atop ZLUDA, AMD ROCm 7 support, and other enhancements.

Building off today's release of Wine 11.0 for enabling countless Windows applications and games to run well under Linux and being the basis of Valve's Proton for Steam Play, Hangover 11.0 is now available. Hangover is the open-source project that pairs Wine with either the FEX-Emu or Box64 emulators for enabling x86 32-bit and 64-bit Windows games/apps to run on native ARM64 Linux systems.

To the frustration of many developers and end-users, back in 2022 Google deprecated JPEG-XL support in Chrome/Chromium and proceeded to remove the support. That decision was widely slammed and ultimately Google said they may end up reconsidering it. In November there was renewed activity and interest in restoring JPEG-XL within Google's image web browser and as of yesterday the code was merged.

ReactOS began 2026 with another "major step" towards Windows NT 6 compatibility with updating its MSVCRT implementation from Wine for the Microsoft C Runtime DLL library. That improved support for a number of Windows applications running on this open-source OS. ReactOS is taking another step-forward now with addressing a very annoying usability issue where up until now you may need to refresh the file manager for seeing folder changes.

The KDE Plasma 6.6 beta release is available today for helping to test this next iteration of the Plasma 6 desktop.

As expected, Wine 11.0 stable was officially released today. This is a big step forward for this open-source software to run Windows games and applications on Linux and other platforms. Wine also serves as the basis for Valve's Steam Play (Proton) that has been critical to the recent successes of Linux gaming.

When it comes to software leveraging Intel Advanced Matrix Extensions (AMX) functionality in modern Xeon processors, it's largely been limited to AI applications/libraries like oneDNN, OpenVINO, DeepRec, etc. But Intel now has another great open-source real-world AMX demonstrator with their Open Image Denoise library. This open-source library providing high quality denoising filters for images rendered using ray-tracing can end up benefiting big time from AMX-FP16 found with the newest Xeon 6 "Granite Rapids" processors. I ran some benchmarks of their new Open Image Denoise library with AMX-FP16 and was honestly blown away by the results.

Building off this past weekend's Debian 13.3 release is now Debian Libre Live 13.3 images for this derivative that ships the install/live media without any of the non-free firmware assets to remain a free software blessed image.

FFmpeg developer Lynne has landed a number of Vulkan-related imporvements to this widely-used open-source multimedia library. Over the past year FFmpeg saw Vulkan shader-based decoding for more video formats, AV1 and VP9 extension work, performance improvements, and other work around Vulkan Video. It will be very exciting to see how FFmpeg delivers in 2026 with Vulkan Video and how the software ecosystem as a whole begins taking up this cross-platform, open industry standard for video encode/decode.

Kent Overstreet has shipped the latest version of bcachefs-tools, the user-space code complementing the Bcachefs file-system kernel driver. There are a number of improvements present in this latest version with Overstreet remaining committed to advancing Bcachefs even with its current out-of-tree kernel status.

Announced today on the Wayland mailing list is wl-proxy as a Rust crate for proxying Wayland connections and intercepting/manipulating Wayland messages.

LLVM/Clang 22 feature development ended overnight with the code now being branched and working toward a stable release likely by the end of February.

The BeOS-inspired Haiku open-source operating system project just published a new status report to detail how they ended out the year.

GCC 16 as this year's major feature release of the GNU Compiler Collection should be out in the typical March~April timeframe if all goes well. Today the GCC 16 compiler transitioned to its final stage "stage 4" of development with a focus exclusively on documentation and regression fixing.
