Nintendo released recently a small system update for improvements to system stability, software compatibility and other adjustments. Though the information was not specific, this version 4.0.3 must be the one update before the summer one which will let people get to the quick-start menu to play the recently-played titles, among other things.
The console downloads the update automatically, so by the time you turn on your system, it should give you a message. This update will just take a few minutes. It is already available in Europe and North America.
