- **Display, hidden, and more:**
- Made display utilities responsive (e.g., `.d-none` and `d-{sm,md,lg,xl}-none`).
- - Dropped the bulk of `.hidden-*` utilities for new [display utilities](({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/display/). For example, instead of `.hidden-sm-up`, use `.d-sm-none`. Renamed the `.hidden-print` utilities to use the display utility naming scheme.

- Added `.float-{sm,md,lg,xl}-{left,right,none}` classes for responsive floats and removed `.pull-left` and `.pull-right` since they're redundant to `.float-left` and `.float-right`.
- **Type:**
- Added responsive variations to our text alignment classes `.text-{sm,md,lg,xl}-{left,center,right}`.
