Yeah let's start on a specific version that they overhauled the API since computers are getting new hardware features, god forbid a different DPI. And use that as a leverage point against a library that kept their API quite stable for the last 20 years!
Especially when comparing Qt against a library who couldn't keep its shit together for 5 years and is infamous for breaking all sorts of API and removing features.

It's not possible to move forwards fast anywhere.

Yeah, this is indeed very unfortunate. They claim the GTK core team is about 2 devs, so tiny that we're lucky the development goes further at all. Hard to understand considering Red Hat became part of IBM.
Perhaps, because GTK developers insist, that GTK2, GTK3, GTK4 are different toolkits.

I'd start with Qt3 to Qt4.
