The Ruby community has experienced some turbulence of late after Ruby Central took control of the GitHub repositories for a number of projects including RubyGems and Bundler. Those projects have historically been developed separately from Ruby itself. They are now being put under the control of Ruby's core team, according to Ruby creator Yukihiro Matsumoto (a.k.a. "Matz"):

To provide the community with long-term stability and continuity, the Ruby core team, led by Matz, has decided to assume stewardship of these projects from Ruby Central. We will continue their development in close collaboration with Ruby Central and the broader community.

Ruby Central has also issued a statement.

Version 13.0 of the Forgejo software forge has been released. Notable changes in this release include content moderation features, ability to require 2FA for users or administrators, and a migration feature for Pagure repositories. The last will be useful for Fedora's move to Forgejo as its new git forge. See the release notes for all changes in 13.0.

• Front: LLMs and copyright; Systemd packaging in Debian; Gccrs; FineIBT; 6.18 Merge window; Interrupt-aware spinlocks; Fedora's /boot.
• Briefs: Linux 6.18-rc1; Librephone; LMDE 7; Ubuntu 25.10; Firefox 144.0; Julia 1.12; Quotes; ...
• Announcements: Newsletters, conferences, security updates, patches, and more.

Boqun Feng spoke at Kangrejos 2025 about adding a frequently needed API for Rust drivers that need to handle interrupts: interrupt-aware spinlocks. Most drivers will need to communicate information from interrupt handlers to main driver code, and this exchange is frequently synchronized with the use of spinlocks. While his first attempts ran into problems, Feng's ultimate solution could help prevent bugs in C code as well, by tracking the number of nested scopes that have disabled interrupts. The patch set, which contains work from Feng and Lyude Paul, is still under review.

Linux Mint Debian Edition (LMDE) 7, based on Debian 13 ("trixie"), has been released:

Its goal is to ensure Linux Mint would be able to continue to deliver the same user experience, and how much work would be involved, if Ubuntu was ever to disappear. LMDE is also one of our development targets, to guarantee the software we develop is compatible outside of Ubuntu.

The LMDE release notes are rather sparse; users are also advised to review Debian 13's release notes.

Greg Kroah-Hartman has announced the release of the 6.17.3, 6.12.53, 6.6.112, and 6.1.156 stable kernels. As usual, each contains important fixes throughout the kernel tree. Users of these kernels are advised to upgrade.

Practically, Librephone aims to close the last gaps between existing distributions of the Android operating system and software freedom. The FSF has hired experienced developer Rob Savoye (DejaGNU, Gnash, OpenStreetMap, and more) to lead the technical project. He is currently investigating the state of device firmware and binary blobs in other mobile phone freedom projects, prioritizing the free software work done by the not entirely free software mobile phone operating system LineageOS.

The 6.18 merge window has come to an end, bringing with it a total of 11,974 non-merge commits, 3,499 of which came in after LWN's first-half summary. The total is a little higher than the 6.17 merge window, which saw 11,404 non-merge commits. There are once again a good number of changes and new features included in this release.

Version 1.12 of Julia has been released. Highlights of the release include new multi-threading features, new tracing flags and macros, and an experimental --trim feature. See the release notes for a full list of new features, changes, and improvements. LWN last covered Julia in January.

Debian packagers have a great deal of latitude when it comes to the configuration of the software they package; they may opt, for example, to disable default features in software that they feel are a security hazard. However, packagers are expected to ensure that their packages comply with Debian Policy, regardless of the upstream's preferences. If a packager fails to comply with the policy, the Debian Technical Committee (TC) can step in to override them, which it has done in the case of a recent systemd change that broke several programs that depend on a world-writable /run/lock directory.
