This is an extremely simple plugin that just adds a link to the toolbar that allows site admins to force WordPress to run a check for plugin updates.

This plugin updates <a href="http://jquery.com/" rel="nofollow ugc">jQuery</a> to the latest official stable version, which is most likely not available within the latest stable release of WordPress. 
jQuery Migrate is also included for backwards compatibility.
No files are replaced, therefore deactivation of this plugin returns your site to it`s original state.
Since WordPress 5.6 includes an up-to-date version of jQuery 3, upgrading shouldn’t`t be necessary in most cases.
Warning
If you are not familiar with beta testing, bugfixing, javascript or running bleeding edge software it`s not recommended. 
I will not provide help on JavaScript and jQuery, only on plugin related issues (PHP)!
Reporting problems
Please post bug reports and request for help on <a href="https://wordpress.org/support/plugin/jquery-updater" rel="ugc">WordPress.org Support Forums</a>.
If you run into any bugs, turning this plugin off will fully deactivate everything.
