To all EU peeps I've successfully updated to the above firmware. No idea what the improvements are other than it now includes the Ukranian language. Anyway, it makes me feel better to have the latest and greatest.(dance)
Nothing obvious. I've already said that I've no idea what the improvements are. I was on 59.00.502 so it's probably bug fixes plus Ukrainian. Anyway, this is for EU only and not North America so you won't be able to install it anyway.
