Update on what happened across the GNOME project in the week from February 02 to February 09.

Sovereign Tech Fund

Sonny says

As part of the GNOME STF (Sovereign Tech Fund) project, a number of community members are working on infrastructure related projects. We didn’t get around to reporting our progress last week because many of us were at FOSDEM in Brussels, so this is work from the past two weeks.

Andy updated his GNOME Online Account work from last year Andy worked on Spiel integration with Orca Sophie added basic filtering of syscalls to glycin bwrap sandboxes via a seccomp allow list

Hubert implemented high contrast hint portal setting in

Sam made a bunch of tweaks to GNOME Shell stylesheet and High Contrast Sam made a new design for Variable Refresh Rate (VRR) Settings Matt implemented the compositor side of Newton, the new a11y architecture prototype

Dor made several improvements to Mutter related to VVR

Dor updated his VVR work and made it ready for review

Dor continued experimentation for getting smooth cursor updates with the KMS thread

Adrian continued his work on systemd-homed integration

Adrian is investigating behavior of kernel’s page cache when encryption keys are removed

Jonas (Dreßler) continued improving Jonas (Ådahl) wayland fractional scaling branch Jonas started work on migrating monitor configs to the new format for enabling fractional scaling by default

Jonas updated the screencast MRs for blocklisting pipelines and hardware encoding

Jonas investigating an issue with variable framerate in screencasts

GNOME Core Apps and Libraries


The low-level core library that forms the basis for projects such as GTK and GNOME.

Philip Withnall says

Maxim Moskalets has added support for --version to GApplication: just call g_application_set_version() in your app to make use of it (https://gitlab.gnome.org/GNOME/glib/-/merge_requests/3889)

GNOME Circle Apps and Libraries


A password manager which makes use of the KeePass v.4 format.

Maximiliano 🥑 announces

Secrets have gained numerous updates during this development season. At first, thanks to his work at Volkswagen, Jan-Michael Brummer has reworked the architecture to support different key providers beside simple key files. Based on this work he added YubiKey and PKCS11 (Smartcard) support. Furthermore Maximiliano revamped UI to make use of libadwaita navigation split view widgets. Last but not least Cleo Menezes Jr. OTP added a quick copy action to the entry rows.


Manage your tasks.

Errands, shines brighter with its latest update this week, packing exciting new features and bug fixes to enhance your productivity experience. New Features:

  • Drag and drop tasks between lists
  • Markdown syntax highlighting in task notes
  • Progress bars for each task

Bug Fixes:

  • Reduced sync requests for faster syncing
  • Improved handling of edits with sync enabled
  • Improved translations


Plot and manipulate data

Sjoerd Stendahl announces

Since Graphs is part of GNOME Circle, we’ve spent some time on updating the infrastructure. The codebase has now been moved to the GNOME GitLab, and translations are now done using the GNOME translation platform. The GitHub page remains available, but only mirrors the GitLab repository. If you wish to get involved or submit an issue, please turn to the GitLab page instead.

Furthermore, we’ve applied some minor quality-of-life changes since last time:

  • Label and title size in the stylesheets can now be set with finer increments.
  • Curves that are hidden are now no longer used when setting the limits of the canvas automatically.
  • The subtitle in the main application now shows the file location without the file name, which is already displayed above.
  • Some minor tweaks under the hood, which should result in slightly faster (about 0.3 s on my setup) start-up times.
  • We updated some strings, and updated the metadata to reflect the move to GNOME GitLab.

The latest release is available on Flathub!

Third Party Projects

Gianni Rosato says

Aviator 0.5.1! TL;DR, mostly SVT-AV1-PSY improvements. But still exciting, in my opinion!

  • The “Open GOP” toggle has been renamed to “oGOP”
  • Speed -1 and -2 are now supported with a warning when you go below Speed 3. Speed -2 can take over 8 hours for a minute of video on a Ryzen 9
  • New “Perceptual Tuning” checkbox toggles some new SVT-AV1-PSY features to “on” by default to improve visual fidelity at the cost of some metric scores
  • Surround sound encodes will now benefit from Opus’s multichannel optimizations
  • Video encoding defaults have been modified, re-enabling temporal filtering by default

ghani1990 reports

Varia download manager has received a new visual identity this week, new icon and a number of new features and improvements, such as:

  • A sidebar that hosts buttons for all downloads, downloads in progress, and completed downloads.
  • A setting for adjusting the simultaneous download amount.
  • Bug fixes and adjustments.

Martín Abente Lahaye announces

After three months of development, Gameeky reaches its first public release.

Gameeky is a learning tool in the shape of a game engine. Therefore, its primary goal is to provide a better learning experience for programming, arts and other STEAM-related skills. More about this rationale here.

This first release comes the following:

  • A game launcher to manage projects more easily.
  • A game client to play games cooperatively.
  • A scene editor to create and modify game worlds.
  • An entity editor to create and modify game objects.
  • A Python library for a LOGO-like experience.
  • Plugins support to extend the games logic and entities behavior.
  • An offline beginner’s guide.
  • The first thematic pack to create role-playing games in a medieval fantasy setting.
  • And more…

Gameeky is available in English and Spanish, including the beginner’s guide.

Check the release post for more information about this project and its future plans.

  • Many UI elements were ported to new libadwaita widgets
  • Visualizers have been moved to bottom bar while the header bar has been simplified/revamped and the secondary header toolbar has been removed
  • The welcome/greeter window has been revamped to look more like GNOME apps
  • Zrythm no longer depends on breeze icons and some icons have changed
  • A bug when copy-pasting audio regions after a BPM change was fixed
  • Zrythm is now fully REUSE 3.0 compliant (license issues reported by reuse lint have been fixed)


ghani1990 announces

David, is embarking on a mission to bridge the gap between the sleek Swift programming language and the established GNOME and Adwaita ecosystem. His efforts go beyond simply bringing Swift to GNOME. he’s actively building Adwaita for Swift, a framework specifically designed to create user interfaces for GNOME applications using an API remarkably similar to Apple’s SwiftUI. This intuitive approach promises to significantly reduce the learning curve for developers familiar with the SwiftUI paradigm, encouraging wider adoption of Swift within the GNOME realm.

Exciting New Developments:

David’s dedication extends beyond the Adwaita for Swift framework. He is actively contributing to the Adwaita-Swift library, introducing a wave of new features designed to further empower developers:

* Support for auto-generated widget bindings * Support for setting a view’s visibility * Enhanced support for signals * Improved onClick observer

Adwaita for Swift’s intuitive API and the continuous improvements to the Adwaita-Swift library hold immense potential to attract new developers, it’s worth noting that this bridge also extends to existing macOS developers. This opens up exciting possibilities for attracting talent and fostering cross-platform collaboration, ultimately benefiting the GNOME ecosystem as a whole.

Flashcards: A Swift Showcase:

David’s recent project, Flashcards application, demonstrates Swift’s potential. Although still in early stages, Flashcards packs simplicity and power. Key features include creating, editing, viewing, and studying sets. Need to prepare for an exam? The test mode has you covered. Plus, importing existing Quizlet sets is a breeze.

This journey towards a more diverse and vibrant GNOME development environment continues, fueled by the dedication and foresight of open-source developers.

Dorothy K announces

As Outreachy interns,we have landed a gnome_locales testsuite to test locale changes for some languages with different alphabets ie. Russian and Japanese and RTL languages ie. Arabic. Check it out here: https://openqa.gnome.org/tests/3294#step/gnome_welcome_locales/13
