The following new features are available in WCS 220.127.116.11
802.11n support-The introduction of the Cisco Aironet 1250 series access point, a business-class access point based on the IEEE 802.11n draft 2.0 standard. The access point offers combined data rates of up to 600 Mbps to meet bandwidth requirements. Cisco WCS display screens include a listing for configuring, managing, and monitoring 802.11n access points and their associated wireless LAN controllers.
The newest WLC and WCS 5.0 trains are now released as well :)
As Rob mentioned, you do need to have the 4.2 code on the WLC's. Also the 1252's require more power that what 802.af can provide. If you use a power adapter or a power injector, then you can run both radio's. If you have the ap plugged into a PoE port that only supplies 15.4W then you can only run one radio. I think you have to remove the other radio, but not sure. There is a new cod for the E series switches that allow for full power and also a new code for the 6500's to supply 16.8W which allows for both radios to power up but only allow the 2.4GHz radio to run at 25mW.
