Renewed or die. It had to happen at some point, and that time is now. Although it has been more than two years since it was launched Qt6, pretty much all software that has anything to do with Qt is still using v5. The latest version of Plasma to launch it will also be the last one to start with that number; the next one will be Plasma 6, and that six will be accompanied by at least two others: Frameworks 6.x and Qt6.
change will be important. In general, when a piece of software has three numbers, for example XYZ, the changes to Z are updates to fix bugs, the ones to Y are bigger and can break compatibility with past versions and the ones to X… well, they are the big changes to TRUE. And you can tell by how KDE has announced the news, albeit indirectly through the KDE neon Twitter account.
Plasma 6.0 is coming in the fall
Kde neon says What are they "Exciting and scary times. 😨😬🤓 The plasma master port to Qt 6 starts today. We've frozen the KDE neon unstable file until it settles«. The first emoji is the most revealing, or worrying? There is some nervousness, but it is normal. It was also with GNOME 40, which was not called GNOME 4.0 so there would be no confusion with GTK4, to the point that Canonical delayed its adoption by six months and Manjaro, a distribution that usually adds changes soon, also took its time until make sure everything was safe to use.
The official KDE account has limited itself to giving the news and a link in which we read:
The master branch for Plasma repos will become Qt6-only tomorrow, 28.02.2023. There will be interruptions due to this. While our goal is to have a basic workspace up and running as soon as possible, non-essential functionality may be broken for a while.
Existing kdesrc-build configurations will be changed to build Plasma from the Plasma/5.27 branch to keep things built with Qt5. Make sure your .kdesrc-buildrc contains "branch-group kf5-qt5".
You can build the Qt6/master version by specifying the "kf6-qt6" branch group.
The move from 4 to 5 in KDE suited him very well, but not so much the move from 3 to 4. We'll still have to wait months to see how things turn out, as Plasma 6.0 is expected to be released. fall or end of 2023. You just have to have faith and not think that this "666" 😈 is going to be bad like others.
