Version 5.0 of the GNU Health Hospital Information System has been released. This project, working to support medical offices, shows just how far the free-software effort can reach. Changes in this release include improved reporting and analytics, more comprehensive handling of many types of patient information, a reworked medical-imaging subsystem, better insurance and billing functionality, and more.

Transparent huge pages (THPs) are, theoretically, supposed to allow processes to benefit from larger page sizes without changes to their code. This does work, but the performance impacts from THPs are not always a benefit, so system administrators with specific knowledge of their workloads may want the ability to fine-tune THPs to the application. On May 15, Usama Arif shared a patch set that would add a prctl() option for setting THP defaults for a process; that patch set has sparked discussion about whether such a setting is a good fit for prctl(), and what alternative designs may work instead.

The extensible scheduler class ("sched_ext") allows the loading of a custom CPU scheduler into the kernel as a set of BPF functions; it was merged for the 6.12 kernel release. Since then, sched_ext has enabled a wide range of experimentation with scheduling algorithms. At the 2025 Open Source Summit North America, Ching-Chun ("Jim") Huang presented work that has been done to apply (local) machine learning to the problem of scheduling processes on complex systems.

The OsmAnd map and navigation app project recently celebrated its 15th anniversary.
All these 15 years can be roughly divided into three stages. For the first five years, we built the very basic functionality—offline maps and navigation that just worked. Over the next five years, we transformed OsmAnd into a full-fledged application with plugins, extensive settings, and professional tools. We dedicated the third five-year period to deep internal work: completely rewriting and improving key components like the rendering engine and routing algorithms.Now, a new, fourth stage begins. We have reached functional maturity, and our main goal for the near future is to polish what we've already built. We will focus on stability, speed, and consolidation. User expectations are growing, and what was once considered normal must now be flawless.

A change proposal to end support for 32-bit x86 (i686) applications on the x86_64 architecture with the Fedora 44 release has been withdrawn after significant pushback. As proposed, the change could have had a significant impact on gamers, compiler development, and the Bazzite project, which uses Fedora as a base for a gaming-focused distribution. While i686 gets a reprieve for now, the question still lingers: who is going to keep the necessary i686 packages in working order when few upstream maintainers or volunteer packagers care about the architecture?
