+	<li>The previous LteHelper method ActivateEpsBearer has been now replaced by two alternative methods: ActivateDataRadioBearer (to be used when the EPC model is not used) and ActivateDedicatedEpsBearer (to be used when the EPC model is used). In the case where the EPC model is used, the default EPS bearer is not automatically activated without the need for a specific method to be called.</li>
