Matthias ☛ JPEG-XL, AppStream, and better media processing
Two weeks ago, I released AppStream 1.2.0. This release contains a lot of great changes, but one of the most important ones concerns how media are being handled, and AppStream’s default image export format.
AppStream is a Freedesktop metadata standard to describe software components. That can be anything from system services over fonts to console and graphical applications. AppStream metadata is supposed to give users enough information to decide whether they want to install a piece of software, to represent that piece of software, and to give the operating system enough information to decide whether a software component should be installed automatically and (to some extent) what capabilities and relations it has, to provide the user with sensible options.

Kdenlive ☛ Parametrized Keyframes - Status Report, September 2026
Besides maintenance and debugging work, this year, my work on Kdenlive was mostly dedicated to refactoring the Kdenlive keyframes system to make it more powerful. This is part of a NGI Zero Commons grant via NLnet, see my last status report from february for some more context.
Previously, keyframes were set globally for an effect, touching all its parameters. With the updated logic, you can now decide to add keyframes only to a specific parameter, and parameters can have independant keyframes. This work will soon be made available for testing, and will be part of the next 26.12.0 Kdenlive release.
This new widget allows to move keyframes for several effects in one step, and also supports keyframe scaling, meaning that you can easily stretch a group of keyframes.
