So we changed to a more secure state ID.. and then send those "secure" ID cards to users via the mail. Because we all know the mail is never abused by identity thiefs :/
Can't speak for the new Illinois license but based on new license in a couple of other states they are probably a bit less durable. However, the changes are in security features that become more noticeable when going through security lines at the airport. It is those security features that allegedly make it impossible to tampering.
