OpenBSD 7.8 has been released. As usual, this release includes a long list of changes; see the changelog for all of the details.

Version 9.0.0 of the Valkey distributed key-value database has been released. Notable features of this release include Multipath TCP (MPTCP) support, new filters for client commands, multi-database support for cluster mode and much more. See the Valkey 9.0.0 RC1 release notes for a full list of new features in this major release.

According to a recent blog post, this release includes major improvements to performance and scaling of Valkey clusters to more than 2,000 nodes and one billion requests per second. Valkey began as a fork of the Redis key-value database in March 2024, but has evolved separately since then.

In September, a group of long-time maintainers of Ruby packaging tools projects had their GitHub privileges revoked by nonprofit corporation Ruby Central in what many people are calling a hostile takeover. Ruby Central and its board members have issued several public statements that have, so far, failed to satisfy many in the Ruby community. In response, some of the former contributors to RubyGems are working on an alternative service called gem.coop. On October 17, ownership of the RubyGems and Bundler repositories was handed over to the Ruby core team, even though those projects had never been part of core Ruby previously. The takeover and subsequent events have raised a number of questions in the Ruby community.

Greg Kroah-Hartman has announced the release of the 6.17.4 6.12.54 6.6.113 6.1.157, and 5.15.195 stable kernels. As usual, each contains important fixes; users of those kernels are advised to upgrade.

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.

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.

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.

Sudden increases in the size of Fedora's initramfs files have prompted the project to fast-track a proposal to increase the default size of the /boot partition for new installs of Fedora 43 and later. The project has also walked back a few changes that have contributed to larger initramfs files, but the ever-increasing size of firmware means that the need for more room is unavoidable. The Fedora Engineering Steering Council (FESCo) has approved a last-minute change just before the final freeze for Fedora 43 to increase the default size of the /boot partition from 1GB to 2GB; this will leave plenty of space for kernels and initramfs images if a user is installing from scratch, but it is of no help for users upgrading from Fedora 42.

Ubuntu 25.10, "Questing Quokka", has been released. This release includes Linux 6.17, GNOME 49, GCC 15, Python 3.13.7, Rust 1.85, and more. This release also features Rust-based implementations of sudo and coreutils; LWN covered the switch to the Rust-based tools in March. The 25.10 version of Ubuntu flavors Edubuntu, Kubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Cinnamon, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, and Xubuntu have also been released.

Firefox has long had support for multiple profiles to store personal information such as bookmarks, passwords, and user preferences. However, Firefox did not make profiles particularly discoverable or easy to manage. That is about to change; Mozilla has announced that it is launching a profile-management feature that will make it easier to create and switch between profiles. According to the support page for the feature, it will be rolled out to users gradually beginning on October 14.

Systemd v258 was released on September 17 after more than nine months of development. LWN has already covered some of the features and changes being readied for v258 before it was final. Now that the release is out, it is time to look at more of what came in v258, including a sandbox shell, new boot options, service-level disk quotas, and enhancements to systemd-resolved.

Despite its name, the Robot Operating System (ROS) is not an operating system; it is a software development kit (SDK) that provides building blocks for robotic applications. One of the main goals of ROS is to present a common API that abstracts away the details of particular hardware drivers or algorithms to make development easier; developers can focus on what a robot should do rather than the low-level details of specific controllers. The latest release of ROS, Kilted Kaiju, features improvements to the middleware layer that is used to deliver data between components.

The Alpine Linux project has announced plans to change its base filesystem hierarchy:

In the future, /lib, /bin, and /sbin will be symbolic links to their /usr counterparts, and every package shall be installed under the /usr paths. For now, /usr/bin and /usr/sbin will continue to be independent paths, but that might change if the Filesystem Hierarchy Standard (FHS) gets updated.

The merge will take place in the upcoming Alpine 3.23 release planned for November; non-merged systems will be considered unsupported when 3.22 is at its end of life in May 2027.
