 **[Reported Bugs](https://github.com/Semantic-Org/Semantic-UI/issues?q=is%3Aissue+milestone%3A2.0.5+is%3Aclosed)**
 
 - **API** - Data replaced in urls, `urlData`, will now be url encoded by default. Additionally checks were added to avoid double encoding already encoded values. #2394
+- **Checkbox** - Fix issue with `onChange` not firing when space key is used. Checkbox keyboard shortcuts now occur on `keydown` but cancel events correctly on `keyup` #2676
 - **Dropdown** - Fixed regression causing `multiple search dropdown` using [`search` inside menu](http://www.semantic-ui.com/modules/dropdown.html#search-in-menu) to break, caused by JS error using "split"
 - **Message** - Fixed issues where icon would overlap in `icon message` when at mobile resolutions due to `flex-collapse` value being incorrect #2665
