 - **Dimmer** - Dimmers now have centered content with a single wrapping `content` element.
 - **Popup** - Popup will now align the center of the arrow (not the edge of the popup) when it would be reasonable (up to 2x arrow's offset from edge). [See this explanation](http://oi66.tinypic.com/2zr2ckk.jpg)
 - **Popup** - Popup can now position elements correctly even when they have a different offset context than their activating element. Like in [this example](https://jsfiddle.net/g853mc03/)
+- **Popup** - Popup `arrowBackground` now inherits from `background` #6059 **Thanks @devsli**
 
 **Bugs**
 - **Modal** - Modal `autofocus` setting now checks to see if currently focused element is in modal, avoiding issues where focus could be set in `onVisible` or `onShow`
