Granted, if I get 10 years of use out of anything built in this century, I do consider it a minor victory.  So maybe that's my answer.

In which case, yes I personally do think they are missing the point of “software”, and I’m happy that our way of developing Qt is not constrained by those industries.

The research done by e.g. DORA around continuous deployment, including in safety critical environments, tells a different story than your anecdotes.

Talk to your sales rep.

Get the patches you need from the dev branch.

Don’t use it.

I don’t consider this substance. Go back to the original thread if you want to spread FUD, Roland.

I started a new one were we can focus on substantial and constructive conversation about what needs to be brought back to make Qt 6 better and porting easier.
