WordPress 5.1 focuses on polish, in particular by improving the overall performance of the editor. In addition, this release paves the way for a better, faster, and more secure WordPress with some essential tools for site administrators and developers.
Newer versions of WordPress come with Site Health features!
With security and speed in mind, this release introduces WordPress’s first Site Health features. WordPress will start showing notices to administrators of sites that run long-outdated versions of PHP, which is the programming language that powers WordPress.
When installing new plugins, WordPress’s Site Health features will check whether a plugin requires a version of PHP incompatible with your site. If so, WordPress will prevent you from installing that plugin.
With these newest updates, you can rest assured that WordPress has security in mind. We suggest you always update regularly or contact your hosting provider to see if you have the right hosting to do updates automatically to keep your web site secured.
