Nope nothing new that I know of has came out. They decided its legal to OC in Overland Park and have not stated if required to obtain the CCW permit to OC. As of now I like how its staying OC and not OC with a crap load restrictions.
Update: Called Overland Park Police Department
Notified that you do not need a CCW/permit to open carry in Overland Park. As long as your legal to own and use a firearm you can open carry.
Kansas City, Kansas: Does not allow open carry any where. No new information has been released about legalizing OC.
