- **Container** - Containers are fixed width containers meant for holding page contents, and are a simpler alternative to `ui page grid`, view more [examples in docs](http://www.semantic-ui.com/elements/container.html#examples)
**Major Changes**
- **Menu** - Menu now uses flexbox. This allows menu items to match each others heights regardless of each items content size. You may need to adjust `floated` content to appear **after**, for example `right menu` should appear after normal menu. This is because `flex` does not use `float`
- **Menu** - Menu now uses flexbox. This allows menu items to match each others heights regardless of each items content size. `right menu` content should now follow left menu content, instead of preceding it (with float).
