qt6 is being updated from 6.2.3 to 6.3.1 in epel9.
There is no soname bump, and everything should be backward compatible.
Why announce it?
Our KDE Plasma Desktop policy is to do a major update only once a year in the main epel repositories.
qt6 is currently NOT part of the KDE Plasma Desktop. Nothing in the current KDE Plasma Desktop depends on it. But, since it is a qt library, I figured some people might think I'm updating the qt library out from under them.
qt5, part of the KDE Plasma Desktop, is not changing.
