 ## Unreleased version
 
-- Fixed the navigation menu so that it would be the same length as the longest sub-menu (#765) 
+- Added `navbar-var-length` config setting that allows the navigation menu to be the same length as the longest sub-menu, so that long words in the submenu are not cut off (#765) 
 - Added `post_search` config setting that creates a Search button in the navbar (older websites need to set `post_search: true` to enable this feature) (#770)
 - Added `edit_page_button` config setting that adds a "Edit page" button to the footer (to edit the current page on GitHub) (#1004)
 - BREAKING CHANGE: More control over RSS feed sharing: previously, an RSS feed was *always* generated, and if the config setting `rss-description` was set then there was an RSS icon in the footer. Now, an RSS feed is only generated when the config setting `rss-description` exists, and an RSS footer icon is only shown if `rss: true` is set in the `social-network-links` config settings
