WordPress 5.5.1 Maintenance Released to Fix Millions of Broken Sites

WordPress published new data that explains why WordPress 5.5 negatively affected millions of sites, a huge number. WordPress is publishing a maintenance release, version 5.5.1. It is designed to fill in as a fix to give time for plugin and theme developers to update their product.

The spreadsheet additionally notes what the particular issue is for each plugin and theme, which will help developers fix their plugins and themes.

WordPress 5.5.1 Maintenance Release September 1, 2020

The WordPress 5.5.1 maintenance release is designed to prevent websites from breaking. Yet, the errors will still need to be fixed.

WordPress portrayed the issue this way:

“In WordPress 5.5 the global JavaScript objects listed below were removed without being deprecated. WordPress 5.5.1 adds a backfill for these globals so they no longer cause JavaScript errors.”

Plugin and theme developers have time until March 2021 to fix the code. Failure to fix the code will bring about another round of site failures.

As explained by WordPress:

“The plan is to remove this fallback code in two major versions, so this will be deleted in WordPress 5.7. This gives plugin and theme developer’s ample time to remove the conflicting code and switch to using wp.i18n”
