Joe Birr-Pixton has written a blog post reflecting on a decade of the Rustls TLS-library project and looking ahead to the upcoming 0.24 release and an eventual 1.0 release.

Rustls began with a first commit on May 2, 2016. Progress was quick: a month later, on June 5, it could interoperate with most sites on the web. The first release, 0.1.0, followed on August 27, 2016 – less than four months after the first commit.

[...] From the 0.1.0 release, the project moved through a long series of releases over the following eight years, building out functionality, hardening and refining the API. That sequence of release lines culminated in 0.23, released on February 29, 2024.

The 0.23 release line has been a stable one: in the time since, it has seen 43 non-breaking releases. That stability didn't come with stagnation. The 0.23 line delivered a wide range of important features, including a FIPS-certified cryptography option, certificate compression, Encrypted ClientHello, post-quantum cryptography, and performance improvements.

Heiko Tietze has published a blog post summarizing the results of a recent survey about the use of LibreOffice's database application, Base. 455 people participated in the survey, including more than 330 who use Base on Linux, with use cases ranging from maintaining records of personal media such as CDs or DVDs to use enterprise-resource planning (ERP) and finance. Of course, users had many ideas how to improve the application:

The majority asks for improvements to the user interface with less clutter and a more attractive design. The workflow and user experience should become either simplified or more powerful, depending on the expertise and the scenario. For example, an elaborate search function is something that many people expect. [...]

Almost the same number of answers requests bug fixes, improvements to stability, and better performance. Issues with queries, forms, and reports were mentioned equally often. In this regard, many replies suggest to remove the Java dependencies.

Typst is a system for typesetting documents into various formats: PDF, SVG, PNG, and, in progress, HTML. It is adept at handling technical material, and is often considered to be an eventual LaTeX replacement. We last looked in on Typst a year ago, when it had reached version 0.13. A new version, 0.15, was released in June with lots of new features, including support for variable fonts, MathML, multiple bibliographies, and more. Typst is free, Apache-2.0-licensed software, programmed in Rust.

A function's return type is supposed to indicate the kind of data that it produces. Rust's "never" type, which is denoted by an exclamation mark ("!"), is the type the language uses to mark a function that never returns and other places where a value can never occur. For a long time, the never type was used internally by the compiler, but was considered an unstable feature. On August 24, after more than two years of work, Rust-compiler-contributor "waffle" finally managed to stabilize the type. It took so long, in part, because it involved a small breaking change to previous Rust editions, which the compiler maintainers needed to ensure did not impact much real code.

Version 12 of the Jellyfin media-management system has been released. Notable changes include database performance improvements, an upgrade to FFmpeg 8.1 for media transcoding, as well as better handling of book and comic media. See the release notes for the web client and server for a full list of changes.

The European Laboratory for Particle Physics, usually just called CERN, is not only the birthplace of the World Wide Web, it is home to the Large Hadron Collider (LHC), the world's largest and highest-energy particle accelerator. As such, its computing environment is both truly unique and of great interest to people outside of CERN who hope to find lessons applicable to their own computing needs. The upcoming migration of some of CERN's systems from CentOS Linux to Debian, which was the topic of a talk at the recent MiniDebConf Winterthur 2026, is of particular interest.

Greg Kroah-Hartman has announced the release of the 7.2.4, 6.18.50, and 6.12.109 stable kernels. Each contains important fixes throughout the tree. Users are advised to upgrade.

The restartable sequences feature is one of the stranger corners of the kernel's user-space interface; it provides a way for user space to carry out simple lockless operations and be informed if it is preempted over the course of an operation (and must, thus, restart). Work merged in the 6.19 release to improve the performance of restartable sequences broke the TCMalloc allocator, which was relying on an undocumented (and unintended) kernel behavior. Now, Olivier Dion is proposing an addition to the restartable-sequences API that will bring TCMalloc back into the fold; it does not make the restartable-sequences API any less strange, though.

Version 2026.08 of the Buildroot embedded Linux system builder has been released. Buildroot 2026.08 includes nearly 1,000 changes from 100 contributors; some of the notable changes include support for Linux 7.1.x, Binutils 2.46.1, GCC 16.2.0, glibc 2.44, as well as adding the M68K and IBM Power 10/11 architectures.

The Asahi Linux project has announced that support for Apple's M3-series chips has been added to the Asahi installer.

Linux support for M3 series SoCs and the machines powered by them is now in a state where almost everything supported on the M1 and M2 series machines just works. This includes the webcam, internal microphones, USB (up to the hardware limit of USB 3 10 Gb/s), hardware accelerated video decoding including support for AV1, WiFi, Bluetooth, and much more! The only major exceptions remain full DCP support and the GPU, which we will have more news on in the coming months. Do not expect performant or power-efficient 3D acceleration right now.

See the blog post for other current limitations of M3 support.

The 7.3-rc2 kernel prepatch is out for testing. Linus said:

This didn't *feel* like a particularly busy rc2, but it clearly was. rc2 is usually the quietest time when people take a breather after the merge window and it takes a while to start finding bugs. But not this time - this is a "full fat" rc release. [...]

Nothing looks particularly odd, even if the rc2 timing is a bit unusual. It might be just random, but we'll obviously all blame it on AI, because whether that's really the cause or not, it's an easy thing to blame ;)

Python's support for multithreaded programs has improved considerably over the last few years with the advent of the "free-threaded" version of the language. But testing multithreaded programs is notoriously difficult, because the underlying host system determines the thread-execution ordering, which adds an element of non-determinism. At PyCon US, Larry Hastings gave a talk (YouTube video) about his blanket project, which is meant to provide mechanisms for deterministic testing of multithreaded Python code.

Version 2026.09, code-named "Hättiwaritätti", of the Debian-based Grml live Linux distribution for system administrators has been released. It is based on packages from the upcoming Debian 14 ("forky") release. Notable changes include an update to the Linux 7.1.8 kernel, support for booting from exfat-formatted USB devices, and an update to GNU Screen 5.0.1.

Tiered-memory systems are built with multiple types of memory, each of which has different performance characteristics. In addition to the usual DRAM, a tiered system might also provide faster high-bandwidth memory or slower CXL memory. On these systems, the placement of memory allocations has a significant effect on the performance that a workload will obtain. While work on tiered-memory improvements has been ongoing for years, it feels like the pace has slowed a bit recently. Even so, there are a few efforts underway, but they are facing questions about whether the tiering design makes sense.

Version 4.0 of the Audacity audio editor has been released. Notable changes in this release include a rewritten interface using Qt, ability to save user-interface layouts as "Workspaces", improvements in working with audio clips, and a new .aup4 project format.

The release is not fully feature-compatible with the Audacity 3.x series; see the compatibility notes for a list of missing features.
