 ## Breaking changes
 
 * `value_box()` no longer defaults to `theme_color = "primary"`. To restore the previous behavior, please use `theme = "primary"`. In addition to the default style change, the `theme_color` is now deprecated in favor of `theme`. (#758)
+
 * `page_navbar()` now defaults to `underline = TRUE`, meaning that navigation links in the navbar now have underline styling by default (set `underline = FALSE` to revert to previous behavior). (#784)
 
+* `layout_column_wrap()` no longer requires `width` and `width` is no longer the first argument, meaning that `width` must be named if used. The new default is `width = "200px"`, which combines with `fixed_width = FALSE`, and produces an automatically responsive layout where each column is at least 200px wide. This means that, in most cases, `layout_column_wrap()` can layout an unknown number of items without you having to set `width`. (#799)
+
 ## New features
 
 * Upgraded the default version of Bootstrap from v5.2.2 to v5.3.1. The most notable thing that comes with the update is the ability to toggle between light/dark [color modes](https://getbootstrap.com/docs/5.3/customize/color-modes/) purely client-side (i.e., no calls to Sass required). (#749, #764)
