Version 5.0 of the Blender animation system has been released. Notable improvements include improved color management, HDR capabilities, and a new storyboarding template. See the release notes for a lengthy list of new features and changes, and the bugfixes page for the 588 commits that fixed bugs in Blender 4.5 or older.
There have been several recent announcements about Linux distributions changing the list of architectures they support, or adjusting how they build binaries for some versions of those architectures. Ubuntu introduced architecture variants, Fedora considered dropping support for i686 but reversed course after some pushback, and Debian developers have discussed raising its architecture baseline for the upcoming Debian 14 ("forky"). Linux supports a large number of architectures, and it's not always clear where or by whom they are used. With increasing concerns about diminishing support for legacy architectures, it's a good time to look at the overall state of architecture support on Linux.
The Homebrew project is an open-source package-management system that comes with a repository of useful packages for Linux and macOS. Even though Linux distributions have their own package management and repositories, Homebrew is often used to obtain software that is not available in a distribution's repository or to install more current versions of projects than are available from long-term-support (LTS) distributions. Homebrew 5.0.0, released on November 12, 2025, expanded Linux support to include 64-bit Arm packages in addition to x86_64, and turned on concurrent downloads by default to speed up package downloads.
Debian developer Simon Josefsson has announced the Debian Libre Live Images project, to allow installing Debian without any non-free software:
Since the 2022 decision on non-free firmware, the official images for bookworm and trixie contains non-free software.
The Debian Libre Live Images project provides Live ISO images for Intel/AMD-compatible 64-bit x86 CPUs (amd64) built without any non-free software, suitable for running and installing Debian. The images are similar to the Debian Live Images distributed as Debian live images.
He does warn that this is a first public release, so there may be problems. See the current list of known issues before trying the images out.
So we have a slightly larger rc6 than usual, but I think it's just the random noise and a result of pull request timings rather than due to any issues with the release. But I guess we have a couple of weeks remaining to find out."
We adopted Rust for its security and are seeing a 1000x reduction in memory safety vulnerability density compared to Android's C and C++ code. But the biggest surprise was Rust's impact on software delivery. With Rust changes having a 4x lower rollback rate and spending 25% less time in code review, the safer path is now also the faster one.
The SUSE Security Team has published an in-depth article on its findings after reviewing a D-Bus service contained in LightDM Greeter by KDE (the lightdm-kde-greeter package) for addition to openSUSE Tumbleweed. The team found a privilege escalation from the lightdm service user to root, as well as other attack vectors in the service:
In agreement with upstream, we assigned CVE-2025-62876 to track the lightdm service user to root privilege escalation aspect described in this report. The severity of the issue is low, since it only affects defense-in-depth (if the lightdm service user were compromised) and the problematic logic can only be reached and exploited if triggered interactively by a privileged user.
The fixes are contained in the 6.0.4 release of the project.
Version 145 of the Thunderbird email client has been released. Notable changes in this release include enabling DNS over HTTPS, support for Microsoft Exchange via Exchange Web Services, and quite a few bug fixes. As of 145, the project is no longer shipping 32-bit binaries for Linux on x86.
Many distributions provide support out of the proverbial box for Flatpak packages, but Fedora is unusual in that it also provides, and defaults, to its own repository of Fedora-built Flatpaks. This has been a source of confusion for Fedora users, who expect to get the Flatpak built by the original developers and hosted on Flathub. It has also been a source of conflict with upstream projects, because users complain of bugs in Flatpak packages they are not responsible for. The situation has also frustrated some Fedora developers, who would prefer to put Flathub's offerings first. A new complaint that Fedora has apparently used manifests from Flathub to build the packages for Fedora—without giving credit to the original authors—has spurred discussions about Fedora's Flatpaks once again. While no concrete changes are on the table, yet, there may be some movement toward addressing persistent complaints.
Version 5.0.0 of the Homebrew package manager for Linux and macOS has been released. Notable changes in this release include download concurrency by default, official support for 64-bit Arm on Linux, and more.
