Nintendo released an update to the Wii U's system software today, a minor revision that brings "further improvements to overall system stability" to the console.
The small, 30 MB update (version 2.1.3 U), released today, is the most recent since Nintendo's December update to the console, which offered similar stability improvements and "other minor adjustments ... to enhance the user experience."
On its support site, Nintendo notes the previously announced Wii U system update scheduled for spring will be released sometime in April. It will add "new features and further improvements to the user experience," Nintendo says.
In January, Nintendo president Satoru Iwata promised two system updates in spring and summer, adding Virtual Console support and speeding up the Wii U's sluggish menus.
