Hello. It is important to note that WordPress 5.5, which will be released on August 11, will remove the “jquery-migrate” script.
As a consequence, any code that still uses jQuery
live()and possibly other old code will likely break. Most notably, WP All Import uses
This means all users that upgrade to WordPress 5.5 and have WP All Import activated (and likely other plugins from your team) will face major breakages in the WordPress admin. It is recommended to update old jQuery code as soon as possible.
