With the update to WordPress 5.5, a migration tool known as <code>jquery-migrate</code> was no longer enabled by default. This may lead to lacking functionality or unexpected behavior in some themes or plugins that run older code.
This plugin serves as a temporary solution, enabling the migration script for your site to give your plugin and theme authors some more time to update, and test, their code.
With the update to WordPress 5.6, the included version of jQuery is also upgraded. This means that old code that previously caused warnings now may instead may cause errors or stop working entirely.
Some of the features no longer working will just stop working behind the scenes without any apparent problem.
The plugin will let you downgrade to a previous version of jQuery for a period, but as a site administrator you are encouraged to get the underlying issue fixed.

Also lets you know when it's no longer needed!!!!

This is what I call going above and beyond. I would rate 10 stars if I could. You deserve it.

Love it, super simple - perfect solution

DEPRECATED: As of WP v5.5 this plugins functionality is included in WP Core and this plugin is not required anymore. If you are running WP v5.5 or greater, you can de-activate and delete/remove this plugin. This plugin will still continue work fine with versions of WordPress less than v5.5.
WordPress will let you install a NEW plugin or theme from a zip file, but it does NOT allow you to upgrade them from a zip file. If you try to upgrade from a zip file, you will get an error message that says “destination already exists” and the upgrade will fail. WordPress will not allow you to upgrade from a zip file.
Update Theme and Plugins from Zip File will allow you to easily upgrade from a zip file, avoiding the “destination already exists” error message.
There is also an option to create a backup copy of the old plugin or theme, in case there is a problem with the new version.
