 **[Reported Bugs](https://github.com/Semantic-Org/Semantic-UI/issues?q=is%3Aissue+milestone%3A2.0.4+is%3Aclosed)**
 - **Popup** - Fixed issues where rounding could cause elements that are against edge of page from not appearing. Add new `jitter` setting for allowing popups to escape page boundaries by a small margin
 - **Visibility** - `refreshOnResize` now correctly includes a default value #2615
+- **Button** - Fixed `fluid buttons` not working correctly with `<button>` due to button tags not supporting `flex` rules. #2617
 
 **Additional Bugs**
 - **Popup** - `wide` and `very wide` popup will now limit themselves to normal popup widths on mobile so that they still appear on screen.
