Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Is anyone using coroutines seriously?
Yes, with boost.asio and with a self written Qt Networking Coroutine Library like QCoro.

Qt Creator 10 Released
You're not completely wrong, but I think this overstating things by a lot. I'll grant you the containers for example, but you can generally use STL algorithms with them. And plenty of old ways of doing things have left modern Qt-based codebases and moved to more modern ways of doing things, including a fair amount of moc macro usage (and yes, you can remove the moc these days, but it has different perf characteristics - cf. the verdigris project).
The community around Qt is pretty active at adopting modern C++, e.g. imho https://github.com/danvratil/qcoro is leading work.

C++20 coroutines explained simply
I though that with the meager support for coroutines that C++ 20 has, it would take ages till I could use that in Qt, but I discovered that it's actually quite nice with QCoro, which is a 3rd part library that is able to leverage coroutines in Qt's event loop with just an add on. I thought it would require extra facilities in the language/library, plus some large patch to Qt to have the first support of them.
