Deprecation Guide for Optional Feature: jquery-integration

Setting the jquery-integration optional feature to true has been deprecated. You must set this feature to false, disabling jQuery integration. This only disables integration with Ember, jQuery can still be included and used as an independent library via the @ember/jquery addon.

For more details on this optional feature, including the changes in behavior disabling it causes and how you can disable it, see the optional features section of the Ember guides.
