### 19.3.1 About Upgrading to jQuery 3.6.4

Learn about upgrading to jQuery 3.6.4.

jQuery 3.x breaks compatibility with earlier 2.x versions. If you application relies on removed jQuery 2.x functionality, you can use the jQuery Migrate plug-in. To include the jQuery Migrate plug-in, go to the User Interface page and set Include jQuery Migrate to On.

Note:

If your application relies on removed 1.x jQuery APIs, be aware that this functionality no longer works as of Oracle APEX release 18.1. You must update the JavaScript to only use jQuery 3.5+ APIs. See the jQuery migration guides to learn more:

- To migrate from 1.x to 2.x, see http://jquery.com/upgrade-guide/1.9/
- To migrate from 2.x to 3.5.x, see https://jquery.com/upgrade-guide/3.5/
