Wii: Mii Contest Channel updated

Mii Contest Channel for the Wii got an update today. In a mail from Nintendo I received on the Wii today it says:

Nintendo would like to inform you that an updated version of the Mii Contest Channel is available.

Included in this update are new features such as the ability to call all your previously-posted Miis in the Posting Plaza, and support for Parental Controls. Please check your Parental Control settings if you find that you are unable to access the Mii Contest Channel.
