After three years of development, Linux hardware provider System76 has declared the COSMIC desktop environment stable. It shipped COSMIC Epoch 1 as part of the long-awaited Pop!_OS 24.04 LTS release on December 11, just in time for Linux enthusiasts to have something to tinker with over the end-of-year holidays. With the stable release out the door, it seemed like a good time to check back in on COSMIC and see how it has evolved since the first alpha. For a first stable release of a new desktop environment, COSMIC shows a lot of promise and room to grow.

The Asahi Linux project has published its progress report following the release of Linux 6.18. This time around the project reports progress on many fronts, including microphone support for M2 Pro/Max MacBooks, work queued for Linux 6.19 to support USB3 via the USB-C ports, and work to improve the Asahi Linux installation experience. The project is also enabling as additional System Management Controller (SMC) drivers, which means that "the myriad voltage, current, temperature and power sensors controlled by the SMC will be readable using the standard hwmon interfaces".

Mozilla has announced a new CEO, Anthony Enzor-DeMeo. Prior to becoming CEO, Enzor-DeMeo was general manager of Firefox and led its "vision, strategy, and business performance". He has published a blog post about taking over from interim CEO Laura Chambers, and his plans for Mozilla and Firefox:

As Mozilla moves forward, we will focus on becoming the trusted software company. This is not a slogan. It is a direction that guides how we build and how we grow. It means three things.

• First: Every product we build must give people agency in how it works. Privacy, data use, and AI must be clear and understandable. Controls must be simple. AI should always be a choice — something people can easily turn off. People should know why a feature works the way it does and what value they get from it.
• Second: our business model must align with trust. We will grow through transparent monetization that people recognize and value.
• Third: Firefox will grow from a browser into a broader ecosystem of trusted software. Firefox will remain our anchor. It will evolve into a modern AI browser and support a portfolio of new and trusted software additions.

Version 8.16.0 of the calibre ebook-management software, released on December 4, includes a "Discuss with AI" feature that can be used to query various AI/LLM services or local models about books, and ask for recommendations on what to read next. The feature has sparked discussion among human users of calibre as well, and more than a few are upset about the intrusion of AI into the software. After much pushback, it looks as though users will get the ability to hide the feature from calibre's user interface, but LLM-driven features are here to stay and more will likely be added over time.

Vojtěch Polášek has announced an unofficial effort to create a Fedora-based distribution designed for visually impaired users:

My ultimate vision for this project is "NO VOJTUX NEEDED!" because I believe Fedora should eventually be fully accessible out of the box. We aren't there yet, which is where Vojtux comes in to fill the gap. [...]

Key Features:
-Speaks out of the box: When the live desktop is ready, Orca starts automatically. After installation, it is configured so that it starts on the login screen and also after logging in.
-Batteries included: Comes with LIOS , Ocrdesktop, Tesseract, Audacity, and command-line tools like Git and Curl. There are also many preconfigured keyboard shortcuts.

See the repository for instructions on getting the image.

So it's Sunday afternoon in the part of the world where I am now, so if somebody was looking at trying to limbo under the merge window timing with one last pull request and is taken by surprise by the slightly unusual timing of the rc1 release, that failed.

Teaching moment, or random capricious acts? You be the judge.

Inspired by the object-capability model, I've been working on a project named capsudo. Instead of treating privilege escalation as a temporary change of identity, capsudo reframes it as a mediated interaction with a service called capsudod that holds specific authority, which may range from full root privileges to a narrowly scoped set of capabilities depending on how it is deployed.

KDE has announced the release of KDE Gear 25.12. This release adds more "extractors" to the Itinerary travel-assistant application, improved Git support in the Kate text editor, better PDF export in Konqueror, and much more. See the changelog for all new features, improvements, and bug fixes.

Version 24.04 LTS of the Ubuntu-based Pop!_OS distribution has been released with the COSMIC Desktop Environment:

Today is special not only in that it's the culmination of over three years of work, but even more so in that System76 has built a complete desktop environment for the open source community. We're proud of this contribution to the open source ecosystem. COSMIC is built on the ethos that the best open source projects enable people to not only use them, but to build with them. COSMIC is modular and composable. It's the flagship experience for Pop!_OS in its own way, and can be adapted by anyone that wants to build their own unique user experience for Linux.

In addition to the COSMIC desktop environment, Pop!_OS is now available for Arm computers with the 24.04 LTS release, and the distribution has added hybrid graphics support for better battery life. LWN covered an alpha version of COSMIC in August 2024.
