I thought it might be for the new Nintendo Channel, but it doesn't seem to have affected anything... if anyone can tell what has changed other than it now being version 4.1E please tell me. Perhaps it is an update just to get ready for the new Nintendo Channel features.

The US version has also been updated. If this is true, than this is the biggest update Nintendo has ever done = the main Nintendo news story of the day (maybe the week). Check it out, http://gonintendo.com/viewstory.php?id=89463

Hmm, another update? Wonder what it is...

That whole list FreeTalkLive mentioned, well, I don't buy it. That would be crazy, and thoroughly unlike Nintendo, totally.

@FreeTalkLive, wow, that is really the Nintendo update email yesterday that I didn't look at.

I'm really excited about the demos and almost all of those features related to Club Nintendo integration.

I updated it yesterday and didn't noticed any change

@FreeTalkLive, that list has to be fake, i dont think nintendo will do all these updates quietly like this

@FreeTalk... is someone pulling someones entire set of limbs off there?....I am pretty sure that the list is bunkum.

All I know is I have got the PAL update, and I can't tell what has happened so there was certainly not any of that.

I don't know if this list is real or not, I have not updated my Wii yet :)

4.1 is just a pre-emptive bug fix for Wii Sports Resort, as far as I know.

That list was a joke on GoNintendo. None of that is in the update.
The 4.1 update was released in Japan about a week after the release of Wii Sports Resort, to fix a bug that caused a conflict between that game and use of the SD card menu. I'm guessing the 4.1 update in other territories is the same thing, only coming before the release of WSR in your case.
