jQuery Migrate's warning about andSelf() is a bit early. It was not removed in jQuery 1.8 or any other version. It is still supported in jQuery 1.11 (latest) and 2.x.

So this isn't a perquisite for the current migration cycle of jQuery. jQuery UI chooses to continue using andSelf instead of addBack so that it is compatible with both old and new jQuery versions. If and when jQuery core removes andSelf, jQuery UI will likely use feature detection and thus no longer trigger this warning.

Cause: The .andSelf() method has been renamed to .addBack() as of jQuery 1.9 to better reflect its purpose of adding back the previous set of results. The old alias was removed in jQuery 3.0.

Still you want to remove this warning.

Solution: Replace any use of .andSelf() with .addBack().

I hope this will help
