There are a couple of other ones! I'd say the most welcome one is the auto 
keyword, allowing us to replace 
        QSortFilterProxyModel *model = new QSortFilterProxyModel(this);
with:
	auto model = new QSortFilterProxyModel(this);

Or
        static SubsurfaceAbout *self = new SubsurfaceAbout(mainWindow());
with:
	static auto self = new SubsurfaceAbout(mainWindow());

Ranged fors would also be neat, but we're using Qt's foreach already so no big 
benefit there.

Yes, we've got nullptr now! And we also have std::nullptr_t, a type that can 
only be assigned the null pointer :-)

But if you want to talk about C++ mistakes, my pet peeve is the >> in 
templates. But if you haven't been writing template code, you probably haven't 
seen it.
