Supported C++ Versions

For code that uses Qt

See https://doc.qt.io/qt-6/supported-platforms.html.

For Qt code

The minimum version is in qcompilerdetection.h. At the time of writing, it can be found on this line. Search for "Compiler version check" if the line has since changed.

The maximum version is in qtbase/configure.cmake. Features for C++ standards greater than the current maximum have AUTODETECT OFF, which means they have to be enabled manually.
