Qt Maintainers
Note: Please do not contact these developers directly unless you want to discuss your contributions. If you need help with Qt, ask in an appropriate forum or join one of our online communities.
Qt's Chief Maintainer is Volker Hilsheimer.
The Component column in this table is what you should choose for "Component/s" when writing up a bug on https://bugreports.qt.io. But there are also some clarification comments in a small font size.
