Today is the simultaneous release of Krita 5.3.0 and Krita 6.0.0!
Depending which version of Qt and KDE Frameworks you build, the same source will result in one of the other. Both versions are almost functionally identical, with 6.0.0 having more Wayland functionality.
Same! Especially since the one recording the demonstration was none other than the creator of Pepper and Carrot. He must be sighing in relief now that lettering his comics will be much more of a breeze.
