This quick update, WordPress 5.5.3 Maintenance Release has fixed an issue introduced in WordPress 5.5.2. With 5.5.2, users were not able to install WordPress on a brand new website that didn’t have a database connection configured. The issue now has been fixed and it does not affect sites where a database connection is already configured.
Earlier, the auto-update system for WordPress updated some sites from version 5.5.2 to version 5.5.3-alpha. This auto-update was due to an error in the Updates API caused by the 5.5.3 release preparations. The 5.5.3-alpha version at this point was functionally identical to 5.5.2 as no development work had been started on 5.5.3; however, the following changes may have been made to your site:
- The default “Twenty” themes installed as part of the pre-release package.
- The “Akismet” plugin installed as part of the pre-release package.
These themes and plugins were not activated and therefore remain non-functional unless you installed them previously. It is safe to delete these features should you prefer not to use them.
Since this is a maintenance release, we suggest you update your site ASAP to avoid fatal errors.
You can either directly download WordPress 5.5.3 or venture over to Dashboard > Updates and simply click “Update Now”. Websites that support automatic background updates are already beginning to update to v5.5.3.
