Hi everyone,
I maintain two applications, and one depends heavily on jQuery.

That is https://github.com/matiasdelellis/quicknotes and now stopped working in NC24, but I can't find any relevant changes that refer to something related.

Uncaught ReferenceError: jQuery is not defined
    <anonymous> https://delellis.com.ar/apps/quicknotes/vendor/colorPick.js?v=30f1e4c7-79:173
colorPick.js:173:1

Of course I am aware of the deprecation warnings for several versions, but it does not seem that you finally remove it.. 🤔
My first attempt is to add jquery to my own installation, but the result is exactly the same. I don't have enough time to port it to VUE, and working with vanilla will still be an important job, but first I need to know what changed in NC24

Please, any help is welcome..

This is the way to go. Bundle it with your app.
