PHP Compatibility for WordPress 6.5 

Efforts are underway to address several compatibility issues in the upcoming 6.5 release, focusing on improving compatibility with PHP 8.0, 8.1, and 8.2. 

With the implementation of a tiered PHP 8+ compatibility plan, each release provides an opportunity to update the official PHP compatibility information for both new and previous WordPress versions. Using data from usage metrics and open compatibility issues of each PHP 8.x version, exceptions will be reviewed, added, or cleared, and updates will be made to the version chart. Significant exceptions may prompt dedicated Make/Core posts with further details.

The official release of PHP 8.3 in late November prompts site operators and hosting companies to inquire about WordPress 6.5 compatibility with the latest PHP version. However, the technical exceptions outlined on the PHP compatibility page may not offer clear answers to users. Therefore, unless there are significant issues running 6.5 on PHP 8.3, publishing an official compatibility notice on WordPress/News, like an example clarifying WordPress 6.4 compatibility on PHP 8.1 and 8.2, could be beneficial.

Rollback Auto Update

Expanding on previous developments introduced in WordPress 6.3, the implementation of rollbacks for automatic plugin updates is in progress. This involves incorporating checks to verify that an updated plugin does not trigger a PHP fatal error while active during an auto-update process. In the event of such an error, it will be identified, and the previously installed version will be reinstated. Additionally, an email notification will be dispatched to the site administrator. 

Managing Plugin Dependencies


Presently, plugins that rely on others (known as dependencies) require administrators to ensure that the necessary dependencies are installed separately, as the plugin won’t function without them. To simplify this process for all users, efforts are underway to establish a consistent method for handling dependencies and guiding users on the necessary steps when installing such plugins. Specifically, the current approach prohibits the activation of a dependent plugin if its dependencies are not installed and activated. In cases where dependencies become unavailable, such as if a dependency’s directory is manually removed, the dependent plugin is automatically deactivated.

Updating the MySQL Version Requirement

MySQL 5.0, which was first released in 2005, reached its end of life (EOL) in January 2012, rendering it unsupported and insecure for more than 12 years. Due to its antiquity, the requirement for the minimum MySQL version is being elevated. With WordPress 6.5, the minimum required MySQL version will be increased from 5.0 to 5.5.5

Additional tips to consider while updating WordPress 6.5

  • Consider Testing on a Staging Site: If feasible, it’s advisable to test the update on a staging site before implementing it on your live website. A staging site functions as a duplicate of your live site, allowing you to make changes and test them without impacting your live environment.
  • Verify Plugin and Theme Compatibility: Before updating WordPress, ensure that all your plugins and themes are compatible with the latest version. Updating them beforehand can help prevent compatibility issues that may arise after the WordPress update. You can find compatibility information on the websites of the plugin or theme authors. 
  • Prioritize Backing Up Your Website: This step is vital. Make sure to create a full backup of your website, including all files, databases, and themes, before you begin the update process. This way, you’ll be prepared to restore your site if anything goes awry during the update.
  • Update themes/plugins before you update WordPress: Before you update your WordPress installation, ensure you update your plugins and themes. Reputable WordPress developers regularly release updates to their plugins and themes to prevent compatibility issues with new WordPress versions. Additionally, outdated plugins and themes may cause security risks, potentially leading to security breaches on your WordPress website. Therefore, it’s crucial to prioritize updating your plugins and themes before proceeding with the main WordPress update.  
  • Clear Browser Cache: Following the update, clear your browser’s cache to ensure that you’re viewing the most recent version of your website.

These recommendations can help ensure a smoother WordPress update process, reducing the risk of complications and optimizing your website’s performance.
