+Spectrum 2 Standard Dialog Migration
+
+To separate itself from another component named "alert dialog," dialog was renamed to "standard dialog." The Divider component is no longer supported in S2 standard dialogs. The class names related to a standard dialog's size (i.e. `--small`, `--medium`, `--large`) have been refactored to reflect T-shirt sizing that other components also utilize. In addition, some new and updated tokens are in place to update the standard dialog corner rounding, font treatments, spacing/padding, and maximum/minimum widths. There were several missing elements of the standard dialog implemented, including optional header and footer content, hero/cover images, and supporting fullscreen layouts.
+
+Modal now uses the updated corner rounding found in the standard dialog design specs. Underlay has an updated comment that addresses the overlay-color/overlay-opacity tokens.
+
+Mod properties are either "new," have been renamed to reflect the "standard dialog" language, or were removed:
