Version 10.6 of OpenSSH has been released. The announcement notes that the OpenSSH team has been receiving a large number of AI-assisted security bug reports. "We very much welcome these reports, especially when combined with human triage, analysis, test-cases and particularly when accompanied by proposed fixes". As a result, the project expects to be making more frequent releases to get updates to users more quickly rather than batching the bug fixes until the next planned release.

Notable changes in this release include enabling the hybrid post-quantum ssh-mldsa44-ed25519 signature algorithm, addition of a -p option for sftp's lmkdir/mkdir commands, as well as disabling the LZ77 dictionary coder in ssh and sshd to mitigate side-channel leaks (which will result in reduced effectiveness of the Compression option). The scp -R option, which allows copies between two remote hosts, is being deprecated due to security risks; the option will be ignored in the future. See the announcement for full details of all changes and bug fixes.

Patch review has long been one of the limiting constraints for the kernel project (and most others); there just aren't enough people to properly review all of the code that is submitted for inclusion. The Sashiko system, which uses a large language model (LLM) to generate reviews automatically, offers the prospect of some relief, and has already become an important part of the kernel's development process. At the 2026 edition of Kernel Recipes, Roman Gushchin, the maintainer of Sashiko, provided an overview of how the system works and what is being done to improve it.

The 7.3-rc6 kernel prepatch is out for testing. Linus said:

Next week might look a bit different: we've got the annual maintainer summit and the Linux plumbers conference going on , so I'll be on the road, as will a number of other maintainers. That may or may not end up changing the stats for -rc7. But it's unlikely to affect the release schedule, although the fact that I have my yearly family vacation the week after that might make the next merge window a bit wonky.

Version 0.17 of the Zig programming language has been released.

This release features 5 months of work: changes from 206 different contributors, spread among 925 commits.

Originally predicted to be shorter, this release cycle ended up [being] substantial, with the Build System reworked, including the introduction of the Build Server Protocol, and the ELF Linker enhanced to the point where we expect Incremental Compilation to work for everyone on x86_64-linux.

LWN last covered Zig in December 2025.

Rust has a number of kinds of smart pointers, both in the standard library and defined by users. Still, some operations that are possible with built-in references are not possible to perform with user-defined smart pointers. Tyler Mandry, lead of the Rust project's language team, spoke at RustConf 2026 about the lengthy effort to change that, and make smart pointers just as flexible as built-in references.

By now it is no secret that large language models (LLMs) have made it easy for people to identify security bugs, and that has resulted in a flood of bug reports to almost every free-software project, including the kernel. At the 2026 edition of Kernel Recipes, Greg Kroah-Hartman took the stage to talk about how the kernel's security team is handling this deluge. His core message was "don't panic".

A lot has happened in the KDE Plasma desktop environment in the last year. Marco Martin, a KDE contributor who spends most of his time working on Plasma, took the stage at Akademy 2026 in Graz, Austria to give an update on Plasma's major new features, some of the minor-but-interesting ones, and a preview of what's coming soon. The biggest upcoming change, dropping X11 support from Plasma, has been well-advertised; but there are also plans afoot to further improve remote-desktop support and more.

Sharon Yang is a Chromium developer who worked at Google on the browser and now works on it at Igalia. On the final day of FOSSY 2026, she gave a presentation on her experiences with both of those companies, comparing and contrasting the ways each one operates and how that affects work on the code base. She enjoyed working at Google and feels the same about Igalia, so the talk was not aimed at complaints—instead it was meant to give a feel for two companies that are rather different.
