Kendo UI for jQuery is tested and compatible with latest jQuery version. Here is the issue that has been closed regarding this: https://github.com/telerik/kendo-ui-core/issues/5019
The jQuery support article soon will be updated shortly.
We are currently not aware of any compatibility problems so far so in case you are experiencing issues please write back to us with the reproduction details so we could be able to research them on our side.
Therefore, you could simply remove the 1.12.4 reference and include the 3.4.1 version.
Hope this helps and lease contact us back in case of further questions.
