Not sure if "Task" is the right category for an issue here, but it's at least a question that came to me.

In Qt 5.14, you introduced a new class QCalendar. Looking at the source file qcalendar.cpp, this seems to be released under only either the commercial license or GPL.

Looking at this commit, this at least doesn't seem to have been intentional. But that change happened only in Qt version 6. All versions between 5.14 and 5.15 don't mention LGPL.

So what does that mean for the license for the QtCore module for these versions? Is this still also available and usable under LGPL as stated here?

Thanks for clarifying!
