With Qt 6 in sight, people need to start moving away from
their deprecated APIs, as we want to remove them all in 6.0.
We are marking deprecated APIs with deprecation attributes,
but by default we're disabling deprecation warnings, making
them an opt-in by the user.
We need to do the opposite: make deprecation warnings enabled
by default, and have an opt-out define.
[ChangeLog][QtCore][Important Behavior Changes] Qt now
enables by default warnings when using APIs marked as
deprecated. It is possible to disable such warnings by
defining the QT_NO_DEPRECATED_WARNINGS macro. The old
QT_DEPRECATED_WARNINGS macro which was used to enable
this warning now has no effect (warnings are automatically
enabled).
