As always we encourage whenever there is a WordPress core update, that you back up your site and get your site updated to the newest version. These will help keep your site more secure.
Whats about WordPress 5.2?
Keeping Your WordPress Site Safe
WordPress 5.2 gives you 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.
After you have your core updated, watch for other updates in the next couple of weeks for plugins installed on your WordPress site and updates to themes. This gives developers time to make adjustments to the new WordPress core changes.
