Improved region checking for discs and titles, the system menu now.Checks for region converted Korean Wii (checks for korean common key inside EEPROM?) if so then brick with a 003 Error.Updates your boot2 to boot2v4, overwriting BootMii/boot2.Most of the IOS's have been updated or stubbed.Use WiiSCU or DOP-Mii to update the shop channel. There is a very small chance of bricking, and the newer methods are very foolproof.

I've softmodded my Wii to run HomeBrew software, and haven't updated the main Wii OS since, the changes are not that important, and if you wait for the new softmod to be avaibable for the new version, you can do it that way.
