Following the Firefox 148 release with the new AI controls, Mozilla promoted Firefox 149 to beta today.

The b4 tool used for managing patch workflows to the Linux kernel has been seeing a lot of work recently on b4 review as the text user interface (TUI) to help expedite the patch review process for the Linux kernel. The b4 review TUI has been integrating AI agent code review helpers powered by the likes of Claude Code too for trying to help enhance the efficiency for Linux kernel patch reviews. That b4 review work is quickly approaching a pre-alpha state.

Greg Kroah-Hartman today extended the planned maintenance periods of the latest Linux 6.18, Linux 6.12, and Linux 6.6 Long Term Support (LTS) kernel series.

With yesterday's stable release of the LLVM Clang 22 compiler it didn't take long for Phoronix readers to begin asking about the performance of this half-year feature update to this prominent open-source C/C++ compiler. What I am seeing so far are no big surprises with the performance largely being similar to Clang 21 across various open-source C/C++ workloads in the testing thus far. This initial round of reference benchmark results between LLVM Clang 22, Clang 21, and Clang 20 were done on an AMD EPYC Turin (Zen 5) Linux server.

Mesa 26.0.1 is now available as the first point release of this quarter's Mesa 26.0 series. Besides the usual bug fixing, Mesa 26.0.1 is more pressing than usual since it contains a security fix for possible out-of-bounds memory access in WebGPU contexts from web browsers.

The first release candidate of systemd 260 is now available for testing. Systemd 260 finally does away with System V service scripts support. Also notable to systemd 260 is the work around the new "mstack" feature.

While there are many great Linux 7.0 features with that still-young development cycle, looking ahead to Linux 7.1 this summer there's an interesting feature on track: cgroup sub-scheduler support for sched_ext.

The EPYC 9005 series for high-end Zen 5 server processors is a year and a half old and then at the lower-end of the spectrum is the EPYC 4005 series AM5 server processors that launched last year. On the embedded side is also the EPYC Embedded 2005 series. AMD has now filled the void between with the long-awaited EPYC 8005 series.

The embargo just lifted on an interesting new industry consortium... CoreCollective. The CoreCollective consortium is focused on open collaboration in the Arm software ecosystem and to a large extent what Linaro has already been doing for the past decade and a half. Interestingly though with CoreCollective for open collaboration in the Arm software ecosystem, AMD is now onboard as a founding member along with various other vendors.

Matthias Clasen shared an update today concerning the state of Scalable Vector Graphics (SVG) within GNOME's GTK toolkit.

Josef Bacik, of Btrfs notoriety before leaving Meta and stepping back from kernel development last year, announced the release of Systing 1.0. Systing is a newer eBPF-tracing tool for Linux complete with AI integration.

Following the big OpenZFS 2.4 release back in December, OpenZFS 2.4.1 was released overnight to ship support for the latest Linux 6.19 stable kernel plus a variety of different bug fixes.

For those making use of the open-source FreeRDP project for your Remote Desktop Protocol (RDP) needs, FreeRDP 3.23 is out today with 11 CVEs addressed in taking care of various security-related issues that have been uncovered.

It's quite a mouthful but today AMD posted Linux kernel patches for preparing SEV-SNP BTB isolation support for further enhancing the security of virtual machines (VMs) for confidential computing.

Lutris 0.5.21 is now available as the latest version of this open-source Linux game manager. With Lutris 0.5.21 comes some new runners for executing games in different environments.

While System76 has been hard at work on a redesigned Thelio desktop chassis design, this hasn't slowed down their software work. Today they shipped COSMIC Epoch 1.0.8 as the newest work on their open-source, Rust-based desktop environment used by their in-house Pop!_OS Linux distribution as well as found in other Linux distributions too.

D7VK is the open-source project that began implementing the Direct3D 7 APIs atop Vulkan and with time the scope expanded to include Direct3D 6 support as well as Direct3D 5 support. Out today is D7VK 1.4 for continuing to enhance the support for these older D3D versions on Vulkan under Linux.

Google Cloud recently launched their N4A series powered by their in-house Axion ARM64 processors. In that launch-day benchmarking last month was looking at how the N4A with Axion compared to their prior-generation ARM64 VMs powered by Ampere Altra. There were dramatic generational gains, but how does the N4A stand up to the AMD EPYC and Intel Xeon instances? Here are some follow-up benchmarks I had done to explore the N4A performance against the Intel Xeon N4 and AMD EPYC N4D series.

A change merged to upstream LLVM Git yesterday for LLVM 23 is moving AMD's HIP to using the new/modern offload driver by default. This aligns with a prior change for NVIDIA CUDA and already in place for OpenMP offloading too.

Following various Intel open-source projects recently being archived with Intel formally discontinuing their development, another wave of Intel open-source projects were formally sunset on Monday.
