There are a number of small, inexpensive, low-powered e-reader or e-paper devices that have promise as ebook readers with one minor problem: the firmware they ship with does not realize their full potential. To solve that problem, the CrossPoint Reader project looks to provide replacement firmware that offers necessary features, better performance, and a more pleasant reading experience. On August 7, the project released version 1.5.0, which opens large EPUBs more quickly, provides offline dictionary lookups, and has reworked settings for changing layout and font options. The release also improves support for right-to-left text as well as Chinese, Japanese, and Korean (CJK) text rendering.

Version 11.1 of the QEMU emulator has been released. The release contains more than 3,200 commits from 285 authors and includes a long list of improvements; see the announcement and changelog for the details.

Virtualization places a guest system into a separate security domain, typically with less privileges than software running directly on the host. Increasingly, there is interest in creating multiple security domains within a single virtualized system as well. CPU vendors (and software vendors too) are implementing solutions; each of which, of course, is different from all of the others. KVM planes, currently under development by Jörg Rödel, Paolo Bonzini, and others in the KVM community, is an attempt to provide an abstraction layer that makes all of these features available on Linux systems; it is not a small task.

GNOME contributor Tobias Bernard has published a blog post that details some of the design team's ideas for the GNOME Shell over the long term:

Some of these we have relatively complete plans for, others are more vague ideas that need more research and prototyping. As always, getting things like these implemented depends on developer capacity and interest (and sometimes funding).

While each of these ideas may require additional discussion, prototyping, and testing, we (the design team) have collected them all together here to share our longer-term vision and to give each idea more visibility.

BPF offers useful safety guarantees, but Kumar Kartikeya Dwivedi wants BPF programs to be even safer. At the 2026 Linux Storage, Filesystem, Memory-Management, and BPF Summit, he led a session (slides) discussing the possibility of adding domain-specific invariants to BPF programs. It was not a discussion intended to lead to the implementation of any particular kernel feature, but rather an overview of why additional formal verification might be needed, and how it could work with the existing BPF ecosystem.

The Django Python web-framework project has announced that it has accepted an annual release cycle proposal. This means that the project is moving from a somewhat complicated schedule that interspersed short-lived feature releases and long-term-support (LTS) releases to a simpler annual cycle where each release is supported for three years.

Every feature release gets three years of support: one year of mainstream bugfixes, then two years of security and data-loss fixes. The "LTS" label is retired — every feature release now carries that same, unique commitment.

No more LTS gap: no racing a deadline to jump two years of changes at once. Upgrade one year at a time, whenever suits you within the support window. Three versions are supported at any time, giving third-party packages a clear, rolling target.

This will take effect with the upcoming Django 2028 release, expected in January 2028.

The 7.2-rc7 kernel prepatch is out for testing. It is still bigger than Linus would like, but he said nonetheless: "I don't currently see any value in delaying the 7.2 release, so I would expect that to happen next weekend unless something really bad pops up."

The 7.1.8, 6.18.44, 6.12.103, and 6.6.151 stable kernels have been released; each contains a fair number of important fixes.

The shadow-utils project provides the tools that handle /etc/shadow, /etc/passwd, and other related databases; in general, manages users and groups on many Linux systems. While most software releases are notable for what is added, the recent shadow-utils 4.20.0 release is most noteworthy for what has been removed. Specifically, several utilities and functionality related to periodic password expiry, which were deprecated in the December 2025 4.19.0 release, have been removed as planned. It is still possible to manage some aspects of password aging with shadow-utils, but organizations that depend on such features should start planning for their complete removal within a few years.

The Software Stewardship Lab, a nonprofit organization based in Scotland, has announced its existence.

Our current research focuses are:

• Software supply chain security — We're working on an observatory that allows users to identify and monitor the world's critical Open Source packages in real time, including previously hidden parts of the dependency graph.
• Maintainer burnout — Our report on burnout in Open Source has been well-received. We're working on yearly follow-ups, plus a companion report on how AI is affecting maintainer burnout.

Moving forward, the Lab's experts will direct funding to and supervise Open Source sustainability researchers doing critical work. We are already working with universities to teach the next generations of software supply chain experts.

Version 1.33.0 of the LightDM display manager has been released. This is the first release in four years: the project had been sponsored by Canonical but was effectively unmaintained in recent years. It has been transferred to a new community repository and is now maintained by Joshua Peisach and Neal Gompa.

The new release includes Qt6 support, code optimizations, and a list of other fixes that had been in limbo pending a new release.

Greg Kroah-Hartman has announced the release of the 6.12.102, 6.6.150, 6.1.182, 5.15.215, 5.10.264 stable kernels. This round of stable kernel releases contains a fix for a single bug, found by Thomas Lamprecht, that affected several of the kernels released yesterday in response to a security vulnerability (CVE-2026-68480) that could allow data leakage through speculative execution.

The 6.12.102 release adds the backported security fix for CVE-2026-68480 to the 6.12 series. As always, users are advised to upgrade.

Security updates have been issued by AlmaLinux (compat-libtiff3, fence-agents, firefox, freerdp, frr, gimp, gstreamer1-plugins-bad-free, java-25-openjdk, kernel, kernel-rt, ldns, libgcrypt, libXfont2, nodejs:22, nodejs:24, p11-kit, pipewire, resource-agents, sg3_utils, thunderbird, and yelp), Debian (async-http-client, jq, kernel, linux-6.1, linux-6.12, redis, and udisks2), Fedora (abrt, chromium, coreutils, curl, freeipa, gst-devtools, gst-editing-services, gstreamer1, gstreamer1-doc, gstreamer1-plugin-libav, gstreamer1-plugins-bad-free, gstreamer1-plugins-base, gstreamer1-plugins-good, gstreamer1-plugins-ugly-free, gstreamer1-rtsp-server, ImageMagick, kernel, libXfont2, php, python-gstreamer1, samba, tcpreplay, and trafficserver), Mageia (firefox, nss, rootcerts, python-django, and thunderbird), Oracle (freerdp, gimp, gpsd, kernel, kernel-uek, and osbuild-composer), Red Hat (buildah and container-tools:rhel8), Slackware (libXfont2 and p11-kit), and SUSE (amazon-ecs-init, azure-storage-azcopy, bind, bouncycastle, cockpit-repos, cockpit-subscriptions, dnsdist, ffmpeg-4, hawk-apiserver, nodejs22, nodejs24, OpenImageIO, openssl-1_1, openssl-3, perl-Mojo-JWT, php8, rsyslog, sssd, and wireshark).

Greg Kroah-Hartman has announced the release of the 7.1.7, 6.18.43, 6.6.149, 6.1.181, 5.15.214, and 5.10.263 stable kernels. These kernels fix a single security vulnerability (CVE-2026-68480) that could allow data leakage through speculative execution. Users of those kernels are advised to upgrade.

The kernel is able to run a few types of executable files, including native binaries in the ELF format and interpreted programs that begin with the #! marker. It also, however, has a mechanism, called binfmt_misc, that can be configured from user space to enable the transparent execution of programs in just about any format. This feature has been relatively static for years, but it seems likely to receive some significant updates in the near future, including the ability to load BPF programs that can decide how to run a given program.

Version 0.10 of the uutils project's Rust Coreutils has been released. This release focused on compatibility with the GNU Core Utilities suite, with Rust Coreutils now passing 645 of 690 tests, up from 625 with version 0.9.0. Notable changes in this release include addition of the mv --exchange option, an OpenSSL backend for checksum utilities, applying SELinux labels at creation when using mkdir, mkfifo, and mknod, as well as a number of performance and security improvements.

The project has an online playground that runs the Rust Coreutils directly in the browser via WebAssembly for those who would like to try the utilities without installing them. LWN covered the uutils project in February 2025.

Security updates have been issued by Debian (7zip, kernel, libde265, and p7zip), Mageia (tomcat), Oracle (fence-agents, frr10, kernel, ldns, libgcrypt, mingw-glib2, nodejs24, osbuild-composer, p11-kit, php8.4, sg3_utils, and thunderbird), Red Hat (libXfont2), and SUSE (containerd, evince, libXfont2, nginx, openssl-3, pcp, php7, php8, python-Django, python-httplib2, python-nltk, rrdtool, vifm, and wireshark).
