Yes, Digia accquired Qt from Nokia last year. But it’s very interesting to see Nokia is still working on some Qt projects.
How do I know it?
Go to Nokia: See the latest career opportunities. Input “qt” in “Keywords” field, and select “Research & Development” in “Job Category” field, click “Search for Jobs” button. At least I got 9 positions, one in US and 8 in Berlin, Germany. It looks like the projects are about Automotive and using Qt and QML.
