Union: Spring 2026 Update

[Konqi]

It has been a long time since I wrote anything about Union, the new style engine being developed for KDE. However, that does not mean nothing has happened in that time. Quite the opposite, in fact (spoiler alert); we plan to do a first release of Union with Plasma 6.7! So let us go over some of the things that happened with Union.

I’d like to thank you guys dearly for reconsidering SVGs as the primary way of designing styles. The original SVG system has always been a pain-point for me and has continually prevented me from even attempting to style my KDE Plasma to how I want it to look. I hope that with the new CSS styling, I can style my desktop to be far more coherent and “my own”!!
