Keeping Sites Safer
Version 5.2 of WordPress, named “Jaco” in honor of renowned and revolutionary jazz bassist Jaco Pastorius, is available for download or update in your WordPress dashboard. New features in this update make it easier than ever to fix your site if something goes wrong.
There are even more robust tools for identifying and fixing configuration issues and fatal errors. Whether you are a developer helping clients or you manage your site solo, these tools can help get you the right information when you need it.
Site Health Check
Building on the Site Health features introduced in 5.1, this release adds two new pages to help debug common configuration issues. It also adds space where developers can include debugging information for site maintainers.
PHP Error Protection
This administrator-focused update will let you safely fix or manage fatal errors without requiring developer time. It features better handling of the so-called “white screen of death,” and a way to enter recovery mode, which pauses error-causing plugins or themes.
Improvements for Everyone
A number of changes work together to improve contextual awareness and keyboard navigation flow for those using screen readers and other assistive technologies.
New Dashboard Icons
Thirteen new icons including Instagram, a suite of icons for BuddyPress, and rotated Earth icons for global inclusion. Find them in the Dashboard and have some fun!
Plugin Compatibility Checks
WordPress will now automatically determine if your site’s version of PHP is compatible with installed plugins. If the plugin requires a higher version of PHP than your site currently uses, WordPress will not allow you to activate it, preventing potential compatibility errors.
The minimum supported PHP version is now 5.6.20. As of WordPress 5.2*, themes and plugins can safely take advantage of namespaces, anonymous functions, and more!
5.2 introduces a wp_body_open hook, which lets themes support injecting code right at the beginning of the element.
*If you are running an old version of PHP (less than 5.6.20), update your PHP before installing 5.2.
