News via wiibrew:
Version 4.2 of the System Menu was released on September 28, 2009.
Deletes most homebrew, including the Homebrew Channel.
Now uses IOS70.
Wii Shop Channel updated. Use WiiSCU or Wii Shop and IOS61 installer to update the shop channel.
Most of the IOS's have been updated or stubbed.
Updates your boot2 to boot2v4 (what LU64+'s have). (That means no downgrading of any IOS, and due to that, you can't revert back to your old System Menu. So BootMii as boot2 installed is removed.)
Have Nintendo gotten rid of Homebrew ? only time will tell
