Guest Access in 4.2.112/130 code

Question

I've just upgraded our controllers from 4.1.185 to 4.2.130 and have noticed some new settings and features for Guest access, specifically on the interfaces and the wlans. Can some one point me to an updated guide on the explanation of these new additions and the recommend setup now? Until I see an explanation on paper so as I can fully understand it, I don't want to change my current setup. i.e. Guest Lan, Ingress Interface, Egress Interface.

the nutshell....
"A growing number of companies recognizes the need to provide Internet access to its customers, partners, and consultants when they visit their facilities. With the new Wired Guest Access feature support on the Cisco WLAN Controllers that uses Cisco Unified Wireless Software Release 4.2.61.0 and later, IT managers can provide wired and wireless secured and controlled access to the Internet for guests on the same wireless LAN controller.
Guest users must be allowed to connect to designated Ethernet ports and access the guest network as configured by the administrator after they complete the configured authentication methods. Wireless guest users can easily connect to the WLAN Controllers with the current guest access features. In addition, WCS, along with basic configuration and management of WLAN Controllers, provides enhanced guest user services. For customers who have already deployed or plan to deploy WLAN Controllers and WCS in their network, they can leverage the same infrastructure for wired guest access. This provides a unified wireless and wired guest access experience to the end users."
