 ### Enhancements
 
 * Enable linking options pages via tabbed-navigation. Will output tabbed navigation for options-pages which share the same `'tab_group'` CMB2 box property. [This snippet](https://github.com/CMB2/CMB2-Snippet-Library/blob/master/options-and-settings-pages/options-pages-with-tabs-and-submenus.php) demonstrates how to create a top-level menu options page with multiple submenu pages, each with the tabbed navigation. To specify a different tab title than the options-page title, set the `'tab_title'` CMB2 box property. See [#301](https://github.com/CMB2/CMB2/issues/301), [#627](https://github.com/CMB2/CMB2/issues/627).
+* Complete the `zh-CN` translation. Props [@uicestone](https://github.com/uicestone) ([#1089](https://github.com/CMB2/CMB2/issues/1089)).
