Simon de Vlieger has released TeamSBC Linux, a highly experimental Fedora Remix built around "Cohesive Linux" principles using systemd's image-based tooling. The primary variant, "Makalu," employs systemd-sysupdate for updates, A/B partitioning, system extensions, and Unified Kernel Images. It currently provides images for virtual machines and Raspberry Pi 4/5 boards. The project aims to test how deeply the cohesive Linux approach can integrate with RPM packaging assumptions. De Vlieger notes it has run for about a week on various devices and is not yet production-ready.

Fedora 45's final release has been pushed to October 27, 2026, remaining in NO-GO status as teams evaluate late-stage blocker bugs. The Atomic Initiative will formally shut down on October 31, transferring bootable image work to the CoreOS Working Group with a new minimal atomic-seed image. Looking ahead, Fedora 46 proposals include transitioning to RPM v6, completely removing the legacy DNF4 stack and modularity, and introducing unprivileged eBPF access via a new daemon.

Starting with Fedora 45, the distribution will replace the legacy kernel framebuffer console (fbcon) with kmscon, a userspace terminal emulator. The change removes fbcon's kernel-space security risks and modernizes font rendering, scrolling, and mouse support, but introduces breaking changes for administrators: virtual consoles now use pseudo-tty devices (/dev/pts/* instead of /dev/tty*), GPU access requires explicit release via kmscon-launch-gui, and traditional tools like setfont and loadkeys no longer function.

Ludovic Rousseau released pcsc-lite 2.5.3, a maintenance update to the free PC/SC implementation for Unix systems used with smart cards and readers. The release addresses a regression in session persistence, improves ATR decoding, and fixes authorization failures for systems using UIDs larger than 65536.

Computational biochemist Vedran Miletić and collaborators have ported the widely used Amber ff14SB and ff19SB protein force fields to GROMACS, extending the molecular dynamics package to support amino-acid-specific backbone corrections. The work required reconciling differences in fundamental constants, parameter precision, and improper dihedral ordering between the two simulation packages. The ported force fields are now part of GROMACS itself, eliminating the need for users to locate and evaluate separate downloads.

Tomaz Canabrava has detailed a new bending trainer screen in Harmonicon, an open-source music practice application built with Rust and the Bevy game engine. The trainer uses FFT-based pitch detection to give harmonica players live visual feedback on bend accuracy, replacing the guesswork beginners face when learning to alter embouchure and throat shape. It supports structured drills, progress tracking across all harmonica techniques, and customizable tolerance settings.

The second Open Transport Community Conference, held in Bern, Switzerland, saw a merger with the OpenTripPlanner (OTP) Summit. The event brought together approximately 140 stakeholders to discuss open data standards like GTFS and NeTEx, as well as specific software developments for transit routing and ticketing.

The update also includes three months of new community translations.

Matthew Garrett has identified potential vulnerabilities in Epic's upcoming Easy Anti-Cheat (EAC2) v2 for Linux. The system relies on eBPF monitoring, Secure Boot, and TPM-based remote attestation to ensure kernel integrity. However, the proposed security measures can be circumvented by resetting the physical TPM module or using a USB-to-SPI bridge to present a legitimate TPM with falsified measurements to the system.

In the twelfth part of his decompilation patterns series, Steinar H. Gunderson discusses how GCC's __builtin_memcpy appears in decompiled output. He explains that what looks like manual loop-based data copying is often an optimized, unrolled memory copy. The article provides guidance on how to simplify these patterns back into readable C code.

Canonical's Myna project, first announced earlier this year, is now available as a technology preview for Ubuntu Desktop users. The tool provides private, offline speech-to-text dictation that runs entirely on the local machine without uploading audio. It supports multiple recognition engines including Parakeet, Whisper, and FunASR, with optional GPU acceleration on supported NVIDIA hardware. The preview is limited to GNOME on Wayland on amd64/amd64v3 systems.

The ALPM project has completed a major refactor of its file parsers for formats like PKGINFO, BUILDINFO, and SRCINFO. Moving away from a generic Serde-based approach and a flawed 'forward-parsing' method, the team implemented a new paradigm using the Winnow library. This change ensures that error messages correctly identify the exact character position where parsing fails, rather than just pointing to the start of a line or a data slice.

Ubuntu 26.10 'Stonking Stingray' introduces multiple security-focused changes: signed GRUB builds drop support for Btrfs, ZFS, XFS, HFS+, LVM, LUKS, and most RAID configurations under Secure Boot to reduce parser attack surface. TPM-backed full disk encryption now works on systems lacking a hardware root of trust, requiring a PIN at installation. The default core utilities are now entirely Rust-based, completing the migration begun in 26.04 LTS. OpenSSL 4.0 and OpenSSH 10.5 add post-quantum algorithms, Encrypted Client Hello, and the upki certificate revocation system. dbus-broker replaces dbus-daemon as the default message bus, and the Rust-based ntpd-rs time daemon is available for testing.

Canonical has added Rust to its devpack series with a new snap package. Devpack for Rust installs via `sudo snap install devpack-for-rust --classic` and provides an interactive TUI for selecting Rustup, an IDE, and command-line utilities like ripgrep, fd, and just. The tool compiles most utilities from source using Rustup, with some pulled directly from the Snap Store. The project is open source under the Canonical GitHub organization.
