The newest version of WordPress, version 4.3, just came out yesterday (8/18, or earlier today from my perspective as I’m still up but it’s after midnight – after all I’m a night owl). So if your site doesn’t autoupdate, go login and update it. Or, download yourself a fresh copy here.
WordPress 4.3 is codenamed “Billie Holiday” in honor of the famous jazz singer. Trivia fact: every version release was named after a jazz musician starting with 1.0, because the core developers share a love for jazz. Look here.
I understand you may be nervous about logging into the backend of your site and updating WordPress. And what about all those plugins, and themes that say they need an update? Are you concerned something might break? Well, let me assure you, you won’t break the Internet, but updates don’t always go without a hitch. WP Night Owl can manage your site so WordPress, plugins, and your theme* are always up to date. Take a look at our maintenance plans – we have 3 tiers to meet varying levels of need.
* To run updates on themes, you must have a child theme (so the parent theme can be updated) or a premium theme with custom settings that are saved in the database, otherwise any customizations would be overwritten.
