 **Major Enhancements**
 - **Progress** - Progress now uses a polling interval for updates. Rapidly updating the progress bar over a period quicker than the animation duration (for example with xhr `onprogress` events say every 50ms) will now appear smooth as butter.
 - **Modules** - Added new setting `silent` to all modules which allows you to disable **all** console output including errors. This can be useful for preventing known errors, like a popup which cannot place itself on screen, or `sticky` content which initializes before it is visible #3713
+- **Modules** - Using `setting` on a setting that is an object literal, for example `error: {}` will now extend the existing object instead of replacing it.
 - **Dropdown** - All dropdowns, not just `selection dropdown`, will now select the first `menu item` that starts with a pressed keyboard key, for example "N" will select "New"
 - **Build Tools** - Added new `autoInstall` option to allow for Semantic to be installed without user interaction. See [docs explanation](http://www.semantic-ui.com/introduction/advanced-usage.html#Auto-Install) for how to use. #3616 **Thanks @algorithme**
