The GIMP project reports that GNOME contributor "balooii" has worked to package GIMP 0.54.1—released in 1996—as a Flatpak that will build and run on modern 64-bit Linux systems. This is a Motif-based version, and the same version that was used by Larry Ewing to create Tux.

While not likely to be useful for serious graphics work today, it should be interesting for users who would like to see what a 30-year-old version of GIMP was capable of.

Probably the biggest change for Python over the last five years or so is the advent of the "free-threaded" version of the language, which removes the global interpreter lock (GIL) and allows multiple threads to run in parallel in the interpreter. At PyCon US 2026, held in Long Beach, California in mid-May, longtime CPython core developer (and current steering council member) Thomas Wouters gave a talk about the feature. He looked at the motivation behind the GIL-removal efforts, some history, the current status of the free-threaded interpreter, and provided a prediction on where it all leads.

Brian Tarricone has announced the first preview release of xfwl4, a Wayland compositor for the Xfce desktop environment.

After close to six months of work, I feel like it's ready to get some wider use, even though of course there will be bugs and missing features. Think of this as an alpha release. [...]

The end goal of xfwl4 is to behave as closely as possible to an Xfce desktop running on an X server. Ideally a user could switch between the two without even knowing there's a difference. In reality, of course, it won't be quite that seamless, and there's still more work to be done to get as close as possible to that ideal. This is a first solid cut at it, at the very least.

The Power Management and Scheduling in the Linux Kernel Summit, which still goes by the historical acronym OSPM, was held in Cambridge, UK, in mid-April. As has become traditional, the presenters at that event have since written summaries of their sessions, and this work has kindly been made available to LWN for publication. The first day's sessions covered a wide range of topics, including idle-state selection, user-space schedulers with sched_ext, lock-holder preemption, and much more.
