A new version of the Internet Channel (the Opera browser for Wii) was released today. Long story short, it supports hardware keyboards, opening links from the message board, sending links to friends, selecting text for searching… and Wiidgets 🙂
If you have the previous version, you should be able to upgrade for free from the Wii Shop Channel.
Update: A more complete changelog can be found on our Wii product pages. There's more to it than meets the eye.
