As regular as they can be, Nintendo has released a new (and tiny) update for the regular and New Nintendo 3DS (both the XL and normal versions of the handheld).
The update version 9.7.0-25 went live on April 20, 2015 and was detailed on the official website of Nintendo where they usually list down all the patch notes.
However, you are not going to find any surprises in that department as well because the notes for the update have brought us that one general statement that Nintendo provides with every update that is made to their consoles and handheld:
Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience.
They did not share any other detail and they also did not explain what the update does to improve the stability and what exactly are those adjustments that they have made to the handheld.
Talking of, if you have downloaded the patch and installed it, you might have experienced some changes. If you have, do share them with us.
The last time we talked about Nintendo 3DS was when Project X Zone 2 was announced; prior to that it was the comparatively much more interesting news from Unity Technologies who revealed that the Unity Engine was now going to support the new 3DS.
Keep checking back for more updates.
