 * As you know WordPress devs finally decided to upgrade to current JQuery version
   in 2020. Now WP core uses latest Jquery + JQuery Migrate, but in the future (
   in WP 5.7 actually – [https://core.trac.wordpress.org/ticket/51812](https://core.trac.wordpress.org/ticket/51812))
   JQuery Migrate will be gone and all deprecations will turn into errors.
    Your
   plugin has following deprecated jQuery events in settings.min.js:
 * jQuery.isFunction()
 * You can see more detailed info about this deprication here – [https://api.jquery.com/jquery.isfunction/](https://api.jquery.com/jquery.isfunction/)
   
   Can you please update the code?

 * Hello again!
 * Thank you for the report 🙂
 * I recently addressed all warnings (not errors) for Extension Manager, but I cannot
   recall ever using or needing `jQuery.isFunction()` in the past.
 * Please make sure that the message is addressed correctly, for we rely on WordPress
   Core code that hasn’t been updated accordingly, which might spawn those messages
   still. It’d be up to the Core developers to address those issues.
 * Nevertheless, if there are upcoming **breaking** changes in WordPress, browsers,
   or PHP, I always make sure to send out updates before the public notices them.
   Deprecation notices and warnings don’t receive such a high priority… if any.
