Version 49 of the GNOME desktop environment has been released. Changes include new default video (Showtime) and PDF-viewing (Papers) applications, a number of calendar improvements, and updates to the Web, Maps, and Software applications.

Ian Jackson has published a blog post summarizing the tag2upload service's first month of handling uploads for the upcoming Debian 14 ("forky") release:

We announced tag2upload's open beta in mid-July. That was in the middle of the the freeze for trixie, so usage was fairly light until the forky floodgates opened.

Since then the service has successfully performed 637 uploads, of which 420 were in the last 32 days. That's an average of about 13 per day. For comparison, during the first half of September up to today there have been 2475 uploads to unstable. That's about 176/day.

So, tag2upload is already handling around 7.5% of uploads. This is very gratifying for a service which is advertised as still being in beta!

LWN covered tag2upload in July 2024.

Version 2.15.0 of libxml2 has been released. Notable changes include the disabling of Python bindings by default, using Doxygen to generate API documentation, as well as bringing HTML serialization and handling of character encodings more in line with the HTML5 specification.

Nick Wellnhofer has also announced that he is stepping down as libxml2 maintainer, and Iván Chavero has volunteered to take over. LWN covered libxml2 in June.

Typst is a program for document typesetting. It is especially well-suited to technical material incorporating elements such as mathematics, tables, and floating figures. It produces high-quality results, comparable to the gold standard, LaTeX, with a simpler markup system and easier customization, all while compiling documents more quickly. Typst is free software, Apache-2.0 licensed, and is written in Rust.

Systemd v258 has been released with a long list of new features and changes; slice units now have basic workload management features, quotas for tmpfs have been added, the "systemctl start" command now has a verbose (-v) option, and more. This release also, finally, completely removes support for control groups v1 support. LWN covered some of systemd v258's features and changes in August.

In October, consumer versions of Windows 10 will stop receiving security updates. Many users who would ordinarily move to the next version are blocked by Windows 11's hardware requirements unless they are willing to buy a newer PC. The "End of 10" campaign is an effort to convince those users to switch to Linux rather than sticking with an end-of-life operating system or buying a new Windows system. At Akademy 2025, Dr. Joseph De Veaugh-Geiss, Bettina Louis, Carolina Silva Rodé, and Nicole Teale discussed their work on the campaign, its progress so far, and what's next.

Security updates have been issued by AlmaLinux (container-tools:rhel8, kernel, and podman), Debian (node-sha.js), Fedora (firefox, kea, and perl-JSON-XS), Mageia (java-1.8.0-openjdk, java-11-openjdk, java-17-openjdk, java-latest-openjdk), Oracle (kernel, libarchive, podman, and python-cryptography), Red Hat (multiple packages, mysql:8.4, and python3.11), SUSE (expat, java-1_8_0-ibm, krb5, libavif, net-tools, nginx, nvidia-open-driver-G06-signed, onefetch, pcp, rabbitmq-server313, raptor, and vim), and Ubuntu (libyang2, linux, linux-aws, linux-aws-5.4, linux-bluefield, linux-gcp, linux-gcp-5.4, linux-hwe-5.4, linux-ibm, linux-ibm-5.4, linux-iot, linux-kvm, linux-raspi, linux-raspi-5.4, linux-xilinx-zynqmp, linux-aws-fips, linux-fips, linux-gcp-fips, and python-xmltodict).

Safe, ergonomic interoperability between Rust and C/C++ was a popular topic at RustConf 2025 in Seattle, Washington. Chandler Carruth gave a presentation about the different approaches to interoperability in Rust and Carbon, the experimental "(C++)++" language. His ultimate conclusion was that while Rust's ability to interface with other languages is expanding over time, it wouldn't offer a complete solution to C++ interoperability anytime soon — and so there is room for Carbon to take a different approach to incrementally upgrading existing C++ projects. His slides are available for readers wishing to study his example code in more detail.

Version 143.0 of the Firefox browser has been released. Changes include the ability to pin tabs by dragging them to the edge, previews in the camera permissions dialog, improved fingerprinting protection, and (optional) automatic deletion of files downloaded in private browsing mode.

The Socket.dev blog describes this week's attack on JavaScript packages in the npm repository.

A malicious update to @ctrl/tinycolor (2.2M weekly downloads) was detected on npm as part of a broader supply chain attack that impacted more than 40 packages spanning multiple maintainers.

The compromised versions include a function (NpmModule.updatePackage) that downloads a package tarball, modifies package.json, injects a local script (bundle.js), repacks the archive, and republishes it, enabling automatic trojanization of downstream packages.

Security updates have been issued by AlmaLinux (kernel and kernel-rt), Debian (node-sha.js and python-django), Fedora (chromium, cups, exiv2, perl-Catalyst-Authentication-Credential-HTTP, perl-Catalyst-Plugin-Session, perl-Plack-Middleware-Session, and qemu), Red Hat (container-tools:rhel8, podman, and udisks2), SUSE (cargo-audit, cargo-c, cargo-packaging, and kernel-devel), and Ubuntu (libcpanel-json-xs-perl, libjson-xs-perl, rubygems, sqlite3, and vim).

Registration for the 2025 Linux Plumbers Conference (Tokyo, December 11 to 13) is now open. LPC tickets often sell out quickly, so it would be best not to delay if you intend to attend.

Brooke Deuson is the developer behind Trafficking Free Tomorrow, a nonprofit organization that produces free software to help law enforcement combat human trafficking. She is a survivor of human trafficking herself. She spoke at RustConf 2025 about her mission, and why she chose to write her anti-trafficking software in Rust. Interestingly, it has nothing to do with Rust's lifetime-analysis-based memory-safety — instead, her choice was motivated by the difficulty she faces getting police departments to actually use her software. The fact that Rust is statically linked and capable of cross compilation by default makes deploying Rust software in those environments easier.

Version 8.0.0 of Varnish Cache has been released. In addition to a number of changes to varnishd parameters, the ability to access some runtime parameters using the Varnish Configuration Language, and other improvements, 8.0.0 comes with big news; the project is forming an organization called a forening that will set out formal governance for the project.

The move also comes with a name change due to legal difficulties in securing the Varnish Cache name:

The new association and the new project will be named "The Vinyl Cache Project", and this release 8.0.0, will be the last under the "Varnish Cache" name. The next release, in March will be under the new name, and will include compatility scripts, to make the transition as smooth as possible for everybody.

I want to make it absolutely clear that this is 100% a mess of my making: I should have insisted on a firm written agreement about the name sharing, but I did not.

I will also state for the record, that there are no hard feelings between Varnish Software and the FOSS project.

Varnish Software has always been, and still is, an important and valued contributor to the FOSS project, but sometimes even friends can make a mess of a situation.

The kernel runs in a special environment that makes it difficult to use many of the development tools that are available to user-space developers. Kernel developers often respond by simply doing without, but the truth is that they need good tools as much as anybody else. Three new tools for the tracking down of bugs have recently landed on the linux-kernel mailing list; here is an overview.

Security updates have been issued by AlmaLinux (cups, kernel, and mysql-selinux and mysql8.4), Debian (cjson, jetty9, and shibboleth-sp), Fedora (bustle, cef, checkpointctl, chromium, civetweb, cups, forgejo, jupyterlab, kernel, libsixel, linenoise, maturin, niri, perl-Cpanel-JSON-XS, python-uv-build, ruff, rust-busd, rust-crypto-auditing-agent, rust-crypto-auditing-client, rust-crypto-auditing-event-broker, rust-matchers, rust-monitord, rust-monitord-exporter, rust-secret-service, rust-tracing-subscriber, rustup, tcpreplay, tuigreet, udisks2, uv, and xwayland-satellite), Oracle (cups, gdk-pixbuf2, kernel, mysql-selinux and mysql8.4, and php:8.2), Red Hat (kernel, kernel-rt, and multiple packages), Slackware (cups, kernel, and patch), and SUSE (busybox, busybox-links, chromedriver, chromium, cups-filters, curl, go1.25, jasper, java-11-openj9, java-17-openj9, java-1_8_0-openjdk, kernel, kernel-devel, kubo, libssh-config, orthanc-gdcm, python-aiohttp, python-eventlet, python-h2, and xen).

The 6.17-rc6 kernel prepatch is out for testing. "But really, none of it is very large. So everything seems slated for a normal release in two weeks. Please do keep testing, so that we don't get complacent."

Creating welcoming communities within open-source projects is a recurring topic at conferences; those projects rely on contributions from others, so making them welcome is important. The kernel has, rather infamously over the years, been an oft-cited example of an unwelcoming project, though there have been (and are) multiple efforts to change that with varying degrees of success. Hans de Goede talked about such efforts within his corner of the kernel project in a talk (YouTube video) at Open Source Summit Europe.

Security updates have been issued by Debian (cups, imagemagick, libcpanel-json-xs-perl, and libjson-xs-perl), Fedora (checkpointctl, chromium, civetweb, glycin, kernel, libssh, ruff, rust-secret-service, snapshot, and uv), Mageia (curl), Red Hat (kernel), SUSE (cups, curl, perl-Cpanel-JSON-XS, regionServiceClientConfigAzure, regionServiceClientConfigEC2, regionServiceClientConfigGCE, trivy, and xen), and Ubuntu (cups, node-cipher-base, and qemu).
