The fourth and final monthly snapshot of Ubuntu 26.04 "Resolute Raccoon" is now available for testing. This alternative to the Ubuntu 26.04 daily ISOs is a monthly test release that also helps exercise the Ubuntu Linux release automation processes.

On recent builds of Ubuntu 26.04 when being prompted by sudo for the password, password feedback is now enabled by default to show asterisk (*) characters when inputting your password. Traditionally sudo has not provided password feedback in the name of security to not divulge the length of your password in case anyone is looking/capturing your screen. But upstream sudo-rs has now changed the default behavior in the name of an improved UX.

Microsoft has published a new version of its open-source DirectX Shader Compiler. Besides adding Shader Model 6.9 production support, making this DX Compiler update interesting to us are the SPIR-V back-end improvements and enhancing interoperability with Vulkan drivers.

For those curious how far Intel laptop CPU performance has evolved over the past nearly two decades, here are power and performance numbers when re-benchmarking all of the Intel-powered laptop CPUs I have on hand that are still operational from Penryn to Panther Lake. A ThinkPad from 2008 with the Core 2 Duo T9300 "Penryn" was still firing up and working with the latest upstream Intel open-source Linux driver support on Ubuntu 26.04 development. On a geo mean basis over the past 18 years from Penryn to Panther Lake, the performance was at 21.5x in over 150 benchmarks. At the most extreme was a 95x difference going from Intel's 45nm Penryn to the 18A Panther Lake.

The Linux kernel continues seeing more open-source kernel drivers emerge for supporting different AI accelerators / NPUs. The newest open-source driver breaking cover today is from NXP and is for enabling their Neutron neural processing unit.

While the Linux 7.0 feature merge window ended this past weekend and that next kernel release won't debut as stable until April, there are already features out on the horizon that are being positioned for likely merging into the Linux 7.1 kernel assuming no issues appear or objections raised by Linus Torvalds. One of the features already looking like it will be submitted for Linux 7.1 is supporting extended attributes on sockets.

Fwupd/LVFS lead developer Richard Hughes of Red Hat today released Fwupd 2.0.20 with continuing to advance firmware updating on Linux systems.

Merged yesterday to Mesa 26.1 for the open-source NVIDIA Vulkan driver "NVK" is ZCULL support for more efficient rendering and bringing some small performance gains to this open-source NVIDIA driver stack.

Merged to Mesa 26.1-devel this week is a minor improvement to the Intel "ANV" Vulkan driver providing some slight enhancements to DirectX 12 games running on Linux by way of Valve's Steam Play with VKD3D-Proton.

AlmaLinux as one of the leading, modern and community-minded alternatives to Red Hat Enterprise Linux (RHEL) continues enjoying very nice growth. In their 2025 Year In Review they provided a look at their growth with now having more than two million systems per week checking in for software updates.

Building off January's GStreamer 1.28 release with many new features, GStreamer 1.28.1 was released today as a point release bringing various fixes and minor additions to this open-source multimedia framework.

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.
