Inside this week's LWN.net Weekly Edition:

• Front: Server-data encryption; PostgreSQL scary patches; Faster kernel builds; BPF for blk-iocost; Lessons learned as DPL.
• Briefs: Brief news items from throughout the community.
• Announcements: Newsletters, conferences, security updates, patches, and more.

PostgreSQL contributor Tomas Vondra has published a blog post looking at development activity in the project, with data from the late 1990s to today.

We're doing ~50 commits per week, give or take. In ~2010 we were doing maybe 25/week, and the trend seems to be a slow and consistent growth. The monthly average makes the trend a bit easier to spot. Which is good, although there's a lot of other important details (size of commits, are they new features or fixes, ...).

It however nicely aligns with the number of active committers, which also grew ~2x between 2010 and today. So maybe that's working as expected.

Pádraig Brady has announced GNU Core Utilities (coreutils) version 9.12. "There have been 288 commits by 16 people in the 21 weeks since 9.11". New features include an -A option for uname which labels all output, as well as adding awareness of the failfs and nullfs filesystem types to stat and tail.

There are many bug fixes in this release as well, including one for a bug "present in 'the beginning'" that caused some utilities to fail when traversing hierarchies if files are being removed in parallel.

What is it like to be a Debian Project Leader (DPL), or a former one? According to Andreas Tille, who stepped down this year after two consecutive terms as DPL, you'd have to be one to know. At the recent MiniDebConf in Winterthur, Switzerland, Tille spoke about what he learned while serving as DPL, some of the initiatives he led, mistakes that he made, and his thoughts on the general resolution (GR) on large language model (LLM) usage in Debian.

Sean Whitton has announced that the original fix for an arbitrary code execution flaw in Emacs (CVE-2024-53920) was incomplete. Bas Alberts discovered that viewing or editing untrusted files in modes other than Emacs's Lisp mode can also result in arbitrary code execution.

This problem affects all Emacs versions affected by CVE-2024-53920. This means Emacs 24 and newer, and possibly also older versions.

A minimal fix, attached, is queued up for release with Emacs 31.2. We (the Emacs upstream maintainers) don't expect to backport the fix to older Emacs releases ourselves.

LWN covered the original vulnerability in December 2024.

According to Kroah-Hartman, this batch may set a record for the number of patches with more than 9,000 in total between them. There are more than 1,800 patches in 7.2.6 alone. Users of these kernels are, of course, advised to upgrade.

All of the videos from the EuroPython 2026 conference, held in Kraków, Poland from July 13 through July 19, are now online along with a recap of the event from conference organizers.

Greg Kroah-Hartman has announced the release of the 7.2.5 and 6.18.51 stable kernels. There are more than 550 patches in each with fixes throughout the tree; users are advised to upgrade.

The Forgejo software-forge project has announced the release of versions 16.0.4 and 15.0.8, which fixes two security vulnerabilities. One is a critical flaw that would allow remote-code execution (RCE):

When generating a new repository from a template repository, Forgejo clones the template repository, removes the .git folder, performs variable template expansion on files listed in .forgejo/template, and initializes a new git repository. During this process, variable template expansion could be misused in order to create a new .git folder, which git would adopt and incorporate during its initialization of a new git repository. A malicious template repository could be used to read arbitrary data from the Forgejo host, and to execute arbitrary processes on the Forgejo host, as a remote code execution attack. To address this issue, after variable expansion is completed, any existing .git folder is removed from the directory before the git repository is initialized.

The project recommends upgrading to the latest version as soon as possible.

PostgreSQL 19 was expected to be released in September, in keeping with the database project's longstanding tradition of a major release every year. However, some late-breaking concerns about several of the features slated for inclusion has some developers worried about the quality of the release. On August 25, PostgreSQL contributor Robert Haas sent an email with the subject "scary patch contest" about several patches that have required an unusually large number of bug fixes leading up to the release, which has raised questions about their readiness for a stable release. One of the patches has been reverted, but several are still under heavy revision, and an extra beta release has been slotted in to allow for additional testing.

Version 1.13 of the Julia programming language has been released. Highlights include faster precompilation of packages, improvements to Julia's REPL, and Juliaup, a graphical interface for the Julia version manager. A full list of changes can be found in the release notes. LWN covered Julia 1.12 in November 2025.

• Briefs: Rustls; Asahi Linux; Buildroot 2026.08; Grml 2026.09; Audacity 4.0; Jellyfin 12.0; LibreOffice Base; Quotes; ...

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.

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.
