With the Wii Shop Channel being down for 3 hours yesterday, it was because Nintendo updated the firmware on the Wii to include many small but nice features and even according to anecdotal evidence increase the speed of the UI. Also updated is the Wii Shopping Channel.
Channels:
Digital Clock added to the Wii Menu right under the channel bar
Forecast Channel now displays the current condition (cloudy, raining, etc.) directly in the Wii Menu in the Forecast Channel box
News Channel can now show 2 scrolling headlines at a time in the Wii Menu, 3 when you click on the button
Message Board now has the "Today's Accomplishments" message as a white message which allows it to stand out from other messages
Address Book entries can now be shifted around using A+B (supposed to be a launch feature) but only to empty spaces.
Calendar in Message Board no longer shows "Today's Accomplishment" only days as having messages.
Wii Shop Channel Overhauled
New Welcome screen detailing 4 Recommended Titles and the points they cost (gone is the title screen bar that had linkable games)
Titles You've Downloaded was moved to the main shop menu
New ways to browse
Popular Titles (2 pages of 10 and includes launch games so not only based on recent info)
