This new update allows for you to back up your downloadable title's save files. Nothing else is known about the update, but it is safe to assume that there are some performance and security updates that came with this update.
In Europe and Japan, you get the same update, plus some new Streetpass features, including new games called Streetpass Squad, Streetpass Garden, Streetpass Battle, Streetpass Mansion. Then there are new puzzles, and now outfits. Rumors have it that the US will get these at a later date.
If you don't know how to do it, you go into your Settings, then go to the selection on the bottom right labeled "Other Settings", then got to the fourth page and select "System Update".

Now Europe and Japan got a different update.
3DS users in Japan and Europe also receive a rather large update for Street Pass Mii Plaza. Here is the changelog:
Two kinds of games in a "bigger" Mii Plaza - ones you've already, plus ones to purchase!
We've now got a Shop, and Exchange Booth, a Check for Updates button and a new Play icon, along with a new second screen menu.
New games - Streetpass Squad, Streetpass Garden, Streetpass Battle, Streetpass Mansion.
New game selection section.
Games are bought with real money, as in eShop purchases.
Streetpass Squad is like Streetpass Quest. Takes place in space. Battle the Gold Bone Gang. Costs £4.49.
Streetpass Garden. You move in to a house in Leafington and try to become a Master Gardener, under the tutelage of Mr Mendel. Grow flowers and decorate your garden. Costs £4.49.
Streetpass Battle. Game of strategy and luck. Rule a remote country in a wartorn land. Your butler, Wentworth, helps you build an army via Streetpass to battle other generals. Ultimate goal to conquer the world! Costs £4.49.
Streetpass Mansion. Spooky paranormal investigation. You're a detective trying to solve the mystery of a haunted house, helped by your assistant Ella Mentree. You work to uncover truth with the help of people you meet inside. Battle enemies to reach the top floor. Costs £4.49.
Exchange booth is locked. Clicking on it doesn't do anything yet.
I downloaded the update, North America doesn't have the new Streetpass. Just the save data backup for digital games. I can confirm that the GBA Ambassador Games, Zen Pinball 3D, and Marvel Pinball 3D can't be backed up. I heard digital New Leaf can't be backed up, but I can't be sure.
Awesome new update! To what firejonie said... really? Aww that sucks :/
No GBA ambassedor games will get backed up, NES ones will, 3DS eShop titles will get backed up, same as swap note, no DSi ware title will get backed up. That is all.
