Wii U System Software 5.4.0 is released. It patches the still-in-progress webkit exploit according to Hykem.
It has been more than 6 months since the last Wii U firmware update 5.3.2 was released. That is a long time considering Wii U is a current gen console. With the 5.4.0 update, official change log includes “Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience” and “Removed “Nintendo TVii” icon on Wii U and HOME menu (because the service will never be launched in Europe)”. The last part is for European Consoles only. It was announced 4 months age that the “TVii” service would never arrive in Europe, so it is only logical to remove the icon.
It is no secret that Hykem who you probably know from Vitasploit (a Playstation Vita hack depending on Webkit) is one of the people working on a webkit exploit for Wii U. According to his tweet, this update patches the vulnerability so if you are waiting for a Wii U exploit like me, it is advised to stay on firmware 5.3.2 and below.
