WordPress 4.1
WordPress 4.1 was recently released, and as always, we’ve updated our WordPress one-click installer to automatically install the latest version for new WordPress sites.
If you’ve previously installed an older version of WordPress, you should update it from within your WordPress Dashboard.
By the way, the new WordPress 4.1 Twenty Fifteen theme doesn’t display a default navigation menu, unlike earlier themes. To ensure you’ll always see a list of the pages on your site, our installer now adds a Pages widget at the top of the sidebar for new installations. If you later create a custom navigation menu, you’ll see two lists of pages in the sidebar. You can just delete the extra Pages widget if that happens to you.
