If you hadn’t heard (or noticed), WordPress 4.2 was released on April 23. As with any WordPress update, “Powell” comes with security enhancements, but most users won’t notice many other differences. You can read more about WordPress 4.2 at https://wordpress.org/news/2015/04/powell/
As always, if you’re a maintenance plan subscriber we’ll be upgrading you to 4.2 (if you haven’t been already). We even tested your site to ensure it’s working properly!
