Recently bought Wifi shield (official) needs firmware update ?

Hello,

I recently bought Wifi official shield, and I don't know if it requires an update.

On this page, http://arduino.cc/en/Hacking/WiFiShieldFirmwareUpgrading, link to the latest version is broken.

Could you provide me some information ?

Thanks

You probably need to upgrade. The new firmware files are included with the IDE.
