From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm not the most knowledgeable on this subject, but I'm curious to learn more.
Why do various toolkits have major releases that seem to reset the features of the last one?
GTK 3 seems like GTK 2 but slower to me, and before the transition was even complete GTK 4 showed up, which just seems like GTK 3 but a bit different. Qt 5 works really well and is efficient on resources, so why are we switching to Qt 6? It seems like reinventing the desktop over and over again.
I understand updates for the kernel for compatibility, small to medium updates to all software for bug fixes and new features, and major updates to toolkits when there are big problems with the current release (X vs Wayland for example). Or if the current release was unreliable and bloated, which I heard was what happened with Qt 4 and why they switched to 5. But I also heard Qt 3 was really stable and lightweight, so why did they switch away from it?
Usually there's big new features that accomodate more modern hardware better. As an example, Qt6 revamps support for Wayland, HDR, and scaling. Even these things on their own don't seem like much, but if you go back to KDE 5 in 10 years time you'll definitely feel like something is plain/dated (or completely not working if you're on new hardware)
Thank you for the explanation! What specifically does Qt 6 do that Qt 5 can't do?
