Today Nintendo has upgraded the Wii's Firmware to version 3.1 The only noticeable feature in this update is that USB keyboards are now fully supported for everything on the Wii, though certain upgrades via the Wii Shop Channel may also be required.
It may or may not also be notable that Nintendo has updated their Internet Usage Policy, but as long as you use the channels as they were designed to be used, it really shouldn't bother you in the slightest.
