center-block has been replaced by mx-auto in Bootstrap 4. mx-auto represents auto x-axis margins (margin=left: auto; margin-right: auto) so it can be used to center display:block or display:flex elements.

          <img class="img-fluid mx-auto" src="https://unsplash.it/200/200" alt="First slide">
