 - **Modal** - `onHide` callback can now cancel event by returning false #3168 **Thanks @mdehoog**
 - **Dropdown** - Added `onLabelRemove` callback that allows value removal to be cancelled by callback **Thanks @goloveychuk**
 - **Table** - Added `selectable` on table cell, allowing for full table-cell links
+- **Popup** Added three new variables for `arrow` background color based on position, top, center or bottom. This makes it easier to use gradient backgrounds with popups and still match arrow colors.
