RPM 6.1 is out today as the newest feature release for this package management system. With RPM 6.1 comes a number of features and improvements as well as a new release model.

For those preferring the tradition of waiting for the first point release of a new Mesa feature release before upgrading, Mesa 26.2.1 is available today with a healthy round of bug fixing.

The Linux kernel has supported the CONFIG_COMPAT_32BIT_TIME Kconfig build time option for optionally disabling of legacy 32-bit time system call support. This is intended to disable the code that uses a 32-bit integer for time that is thus not Year 2038 safe, but at the cost of breaking compatibility for legacy 32-bit applications. Even if building without Linux 32-bit time support, it turns out some 32-bit time code persisted but that is now being fixed with Linux 7.3.

KDE Gear 26.08 was released today to deliver the latest collection of KDE application updates.

Following today's release of XWayland 26.1 RC1, X.Org Server 26.1 RC1 was tagged. This xorg-server 26.1 release is aiming to become the first major feature release in five years, succeeding the xorg-server 21.1 series.

In addition to the IOmap improvements helping EXT4 performance in Linux 7.3, the main EXT4 feature pull request has now been submitted for this next kernel version. That pull is set to land yet more performance optimizations for EXT4.

Andrew Morton on Tuesday sent out all of the memory management "MM" updates for the Linux 7.3 merge window. The MM pull was particularly heavy as he noted 1,250 "added-to-MM" emails were sent out this cycle compared to 920 the prior cycle. With a lot of patch churn, he also turned to Google's Gemini AI for writing his patch summaries. In going through the very verbose AI-generated summary, there are two patch series that get me excited on the performance front with Linux 7.3.

Go 1.27 was released today as the newest version of this programming language from Google's Go team.

David Sterba of SUSE sent in the Btrfs file-system feature updates today that target the Linux 7.3 merge window. Among other changes are more performance improvements for this next version of the Linux kernel.

With today's memory prices, a frequent question at Phoronix and throughout many organizations is about reducing cost by not necessarily populating all memory channels. Especially with modern servers going up to 12 memory channels per socket or even 16 memory channels with upcoming EPYC Venice, you may be curious about the performance impact of populating less memory channels to see if the trade-off is worthwhile given today's DDR5 RDIMM pricing. In this article are benchmarks from a Dell PowerEdge server looking at a dual AMD EPYC 9655 2P configuration when testing between four and the full twenty-four DDR5-6400 RDIMM configuration and the resulting performance impact in more than 250 benchmarks.

Olivier Fourdan of Red Hat announced today the first release candidate of XWayland 26.1. This is the first new tagged feature release since XWayland 24.1 back in 2024! As such there are many new features in tow.

All of the SoC updates have been merged for the Linux 7.3 kernel that include adding some new SoCs as well as deprecating several older 32-bit ARM platforms. In turn with those platforms deprecated, "hundreds" of drivers are now orphaned in the process.

A Phoronix Premium supporter recently relayed a request to see some fresh PHP performance benchmarks. So here are some fresh numbers of PHP 7.4 through the latest PHP 8.5 code plus the current Git state of PHP 8.6 ahead of the official PHP 8.6.0 release later in the year. With PHP 8.6 is also a fresh look at the JIT performance enabled too.

The exciting set of scheduler updates have been merged for the Linux 7.3 merge window.

Covered first on Phoronix back in June was an AMD Linux patch for introducing a new "low power" CPU core type to complement their typical "performance" cores and their "efficiency" cores like with Zen 4C/5C. That low power core is presumed for some Zen 6 clients and that integration is now merged for Linux 7.3 as well as unifying the Intel/AMD CPU core type handling.

The newest Raspberry Pi product to launch is the Raspberry Pi Compute Module 5 Programming Jig.

Modular, the AI startup founded by Chris Lattner of LLVM and Swift fame, has open-sourced their Mojo systems programming language! This comes following the recent acquisition of Modular by Qualcomm.

COSMIC Epoch 1.6 was released this evening as the latest milestone for this open-source, Rust-based desktop environment led by System76 as part of the work on their Pop!_OS Linux distribution.

Merged earlier this year for Linux 7.1 was extended attributes on sockets support as a feature sought after by the likes of GNOME and systemd for helping with Varlink IPC usage and other purposes. A limitation though of the functionality has been no efficient means for a BPF program to read those user extended attribute labels back. But with Linux 7.3 that's being addressed with the new bpf_sock_read_xattr() kernel function.

As part of the VFS pull requests now merged to the Linux 7.3 development kernel was an improvement to the IOmap framework used by various file-systems for mapping logical file byte offsets in memory to their physical locations on storage. With the now-merged code, this modern block mapping framework is allowing better performance at least for the EXT4 file-system.
