• Curated by Felix

Update on what happened across the GNOME project in the week from August 18 to August 25.

GNOME Core Apps and Libraries


Cross-platform widget toolkit for creating graphical user interfaces.

Emmanuele Bassi says

Thanks to René de Hesselle from the Inkscape community, GTK has a new macOS CI runner


Core system user interface for things like launching apps, switching windows, system search, and more.

GNOME Shell 45 port guide is out. Since GNOME Shell 45 moved to ESM, we want all developers to port their extensions before 45.0 release (September 20th) so they can report to us about the elements needed to be exported (in case they are not exported already).

We also offer our help to all developers on GNOME Discourse and GNOME Extensions Matrix channel: GNOME Matrix Channel IRC Bridge: irc://irc.gimpnet.org/shell-extensions

GNOME Development Tools


A profiling tool that helps in finding the functions in which a program uses most of its time.

hergertme says

Sysprof gained the ability to show you what processes were scheduled per-CPU. You can use this to more effectively nail down performance issues on the desktop.

GNOME Circle Apps and Libraries

Clara Hobbs (she/they) announces

Thanks to the new AdwBreakpoint API in libadwaita 1.4, Chess Clock just merged improved support for larger screen sizes. The clock text is larger when the window is big enough to support it, and portrait mode is enabled whenever the window has a portrait aspect ratio (rather than requiring it to be as narrow as a portrait phone screen). These updates should make the app nicer to use on tablets and laptops.


A sandbox to learn and prototype with GNOME technologies.

Rust support landed in Workbench 🛠️ ❤️ 🦀 Thanks to Julian 🍃 ! We will work on formatter and language server soon.

We are approaching 100 Library demos. Porting them is a great opportunity to learn or work with Rust, specially if you are coming from JavaScript or Vala. Checkout our guide and don’t hesitate to come by #workbench:gnome.org

Third Party Projects

Bilal Elmoussaoui reports

A new release of libmks is out! Adding support for touch events, improving the rendering which would avoid frame drops/incorrect regions updates. Details at https://gitlab.gnome.org/GNOME/libmks/-/releases/0.1.1. I also wrote a blog post recently about my adventures to get damage area propagated from the guest to the host which you can read at https://belmoussaoui.com/blog/16-damage-areas-across-the-virtio-space/

GNOME Foundation

Caroline Henriksen announces

With GUADEC 2023 completed Foundation staff have been busy wrapping up final conference tasks while moving forward with planning GNOME.Asia 2023, LAS 2024, and GUADEC 2024. Some of these tasks include collecting feedback from our post-event surveys, sorting through conference photos, and providing updates to our event sponsors. We’re currently working on finding the best solution for sharing the conference photos with everyone and will provide more updates on that soon! We’re also looking for community feedback on how we structure GUADEC 2024 talk and BoF days. Let us know if you would prefer to attend GUADEC talks on weekdays or over the weekend by answering our poll here.

Outside of events, we’ve been wrapping up the 2021-2022 Annual Report which is now available on the Foundation website, and getting started on a new video for the upcoming GNOME 45 release.

Reminder: The GNOME.Asia 2023 Call for Participation is open! If you would like to submit a talk to this year’s summit please read our news post for more details. All applications are due by September 1, 2023.

Volunteer Opportunity: We’re live-streaming the GUADEC talks, but are looking for a volunteer to edit the final footage into individual talk videos. If that sounds like a project you’re interested in let us know by emailing chenriksen@gnome.org.
