The user Klaro suggested to restore the old visibility classes, which is a good idea. Unfortunately, their solution did not work in my project.

I think that it is a better idea to restore the old mixin of bootstrap, because it is covering all breakpoints which can be individually defined by the user.

Here is the code:

// Restore Bootstrap 3 "hidden" utility classes.
@each $bp in map-keys($grid-breakpoints) {
  .hidden-#{$bp}-up {
    @include media-breakpoint-up($bp) {
      display: none !important;
    }
  }
  .hidden-#{$bp}-down {
    @include media-breakpoint-down($bp) {
      display: none !important;
    }
  }
  .hidden-#{$bp}-only{
    @include media-breakpoint-only($bp){
      display:none !important;
    }
  }
}

In my case, I have inserted this part in a _custom.scss file which is included at this point in the bootstrap.scss:
