BREAKING CHANGES
The responsive display classes found in the `display.css` file have had their media queries updated to better reflect how they should work. Instead of using the maximum value of that breakpoint (for `.ion-hide-{breakpoint}-down` classes) the maximum of the media query will be the minimum of that breakpoint.
