 ### Version 2.0.3 - July 8, 2015
 
 **[Reported Bugs](https://github.com/Semantic-Org/Semantic-UI/issues?q=is%3Aissue+milestone%3A2.0.3+is%3Aclosed)**
+- **Checkbox** - Checkbox initialized with JS and with `for/id` matching would cause toggle to occur twice on click (making it seem as if nothing was updated) **thanks @malacalypse** #2572
 - **Steps** - Last `step` no longer incorrectly shows arrow #2552
 - **Modal** - Modal that is larger than page height will now correctly reset body height on remove #2576
 - **Popup** - Popup `preserve` setting (which preserves popup in DOM to avoid regenerating on each show/hide) was set to `true` by default causing generated popups to remain in DOM. #1369
 - **Input** - Fixed errored input field having incorrect border radius with `labeled input`
 - **Divider/Grid** - `vertical divider` no longer has inexplicable right border when stacked on mobile #2558

 **Additional Bugs**
 - **Form** - URL regexp will now match now works correctly, and matches against non `http://` prefixed urls like `www.google.com`
