Unpacking Python iterables of various sorts, such as dictionaries or lists, is useful in a number of contexts, including for function arguments, but there has long been a call for extending that capability to comprehensions. PEP 798 ("Unpacking in Comprehensions") was first proposed in June 2025 to fill that gap. In early November, the steering council accepted the PEP, which means that the feature will be coming to Python 3.15 in October 2026. It may be something of a niche feature, but it is an inconsistency that has been apparent for a while—to the point that some Python programmers assume that it is already present in the language.

Version 8.5.0 of the PHP language has been released. Changes include a new "|>" operator that, for some reason, makes these two lines equivalent:
$result = strlen("Hello world");
$result = "Hello world" |> strlen(...);
Other changes include a new function attribute, "#[\NoDiscard]" to indicate that the return value should be used, attributes on constants, and more; see the migration guide for details.

In July, Collabora announced the Rust-based Tyr GPU driver for Arm Mali GPUs. Daniel Almeida has posted an update on progress with a prototype of the driver running on a Rock 5B board with the Rockchip RK3588 system-on-chip:
The Tyr prototype has progressed from basic GPU job execution to running GNOME, Weston, and full-screen 3D games like SuperTuxKart, demonstrating a functional, high-performance Rust driver that matches C-driver performance and paves the way for eventual upstream integration! [...]
Tyr is not ready to be used as a daily-driver, and it will still take time to replicate this upstream, although it is now clear that we will surely get there. And as a mere prototype, it has a lot of shortcuts that we would not have in an upstream version, even though it can run on top of an unmodified (i.e., upstream) version of Mesa.
That said, this prototype can serve as an experimental driver and as a testbed for all the Rust abstraction work taking place upstream. It will let us experiment with different design decisions and gather data on what truly contributes to the project's objective.
There is also a video on YouTube of the prototype in action.

BPF allows programs uploaded from user space to be run, safely, within the kernel. The io_uring subsystem, too, can be thought of as a way of loading programs in the kernel, though the programs in question are mostly a sequence of I/O-related system calls. It has sometimes seemed inevitable that io_uring would, like many other parts of the kernel, gain BPF capabilities as a way of providing more flexibility to user space. That has not yet happened, but there are currently two patch sets under consideration that take different approaches to the problem.
