   - We've dropped the `.embed-responsive-item` and element group selector in favor of a simpler `.ratio > *` selector. No more class needed, and the ratio helper now works with any HTML element.
   - The `$embed-responsive-aspect-ratios` Sass map has been renamed to `$aspect-ratios` and its values have been simplified to include the class name and the percentage as the `key: value` pair.
   - CSS variables are now generated and included for each value in the Sass map. Modify the `--aspect-ratio` variable on the `.ratio` to create any [custom aspect ratio]({{< docsref "/helpers/ratio#custom-ratios" >}}).
+- "Screen reader" classes are now ["visually hidden" classes]({{< docsref "/helpers/visually-hidden/" >}}).
+  - Changed the Sass file from `scss/helpers/_screenreaders.scss` to `scss/helpers/_visually-hidden.scss`
+  - Renamed `.sr-only` and `.sr-only-focusable` to `.visually-hidden` and `.visually-hidden-focusable`
+  - Renamed `sr-only()` and `sr-only-focusable()` mixins to `visually-hidden()` and `visually-hidden-focusable()`.
+
+### Utilities
+
+- #31280: Added new [position utilities]({{< docsref "/utilities/position/#arrange-elements" >}}) for `top`, `right`, `bottom`, and `left`. Values include `0`, `50%`, and `100%` for each property.
+  - We also added new `translate` utilities to accompany those position utilities for centering elements when they're being positioned.
+  - Some great examples have been added to the docs to show these off.
+- [#31484](https://github.com/twbs/bootstrap/pull/31484): Added new [`border-width` utility]({{< docsref "/utilities/borders/#border-width" >}}).
+- #31473: The `.d-none` utility was moved in our CSS to give it more weight over other display utilities.
