There's also now improved reliability for synching Safari bookmarks and Reading List and a fix for an issue where an 'Unable to purchase' alert displayed after a successful purchase.You can either get the update the 'old' way, using iTunes after plugging the device into a computer. Or you can get it over-the-air (OTA), by heading to Settings > General > Software Update. It's around 54MB in size, so make sure you are in a Wi-Fi zone.
