ordPress 5.2 “Jaco” Released, Includes Fatal PHP Error Protection and A Recovery Mode.

WordPress 5.2 “Jaco” named after bassist Jaco Pastorius, is now available for download. Normally, I’d start listing new features but I’m going to do something a little different this time.

Let’s begin by recognizing the 327 people who contributed to this release with 109 of those being first time contributors. It was led by Matt Mullenweg, Josepha Haden Chomphosy, and Gary Pendergast. Included in the list is Alex (Viper007Bond) Mills who passed away from Leukemia earlier this year.

Mills still has a few uncommitted patches in Trac so it’s possible he’ll end up on the list of contributors in future releases.

Minimum PHP Version Required to Run WordPress 5.2 Is Now 5.6.20

WordPress 5.2 bumps up the minimum PHP version required to 5.6.20. If you’re using an older version, you’ll need to update PHP before upgrading to WordPress 5.2. Updating PHP to version 7.3 or above is recommended.

Additional Improvements to Site Health Check

In WordPress 5.1, Site Health Check features were added to inform users of outdated PHP versions. WordPress 5.2 builds on this foundation by adding two new pages that help debug common configuration issues. Users can find the Site Health section in the WordPress backend by browsing to Tools > Site Health.

Browsing to the Site Health page triggers a series of tests. When the tests are performed, errors and recommended improvements are displayed on the results page. There’s also a an Information tab that displays every detail about the configuration of your site.

Theme and Plugin authors can add their own tests and modify or remove existing ones with filters.

Fatal Error Protection

Instead of seeing the dreaded “white screen of death,” WordPress 5.2 includes fatal PHP error protection. When a fatal error is detected, a user-facing error message is displayed and an email is sent to the administrator’s email address.

The email includes a link to a new feature called “recovery mode.” While in recovery mode, plugins and themes that are causing fatal errors are put into a paused state to ensure administrators can work around the errors and access the backend normally.

In addition to being informed about which themes or plugins are causing fatal errors, administrators have at least three options to fix the issue.

  • Administrators can deactivate the theme or plugin to maintain a working version of the site.
  • Administrators can fix the problem if they have the technical capabilities, and afterwards reactivate the theme or plugin.
  • Administrators can file a support request with the developer, pointing out the error.

Administrators can exit recovery mode by pressing a button in the admin bar. A few examples on how developers can utilize this feature can be found here.

WordPress 5.2 also includes accessibility improvements, thirteen new dashboard icons, plugin compatibility checks, and an variety of changes to the block editor. In addition, the Privacy Policy page includes four new helpers that make customizing and designing the page easier.
