Both the Nintendo Switch and Nintendo Switch 2 have received an official firmware update. System software version 20.4.0 has rolled out to consoles, and you'll never guess what Nintendo tweaked with this brand new update: "General system stability improvements to enhance the user's experience." Scene dataminer OatmealDome looked into the new firmware, and discovered that for the Switch 1, the web browser was updated, alongside the controller-handling code, while the changes for the Switch 2's firmware are a bit more unclear. Currently, Nintendo's website only shows the update having released for those with Japanese consoles.

Wow! Another boring update!

So the switch part is switching firmware numbers. Got it.

 

[MPRTwice]

A generally grievous and uncivilized situation.

Switch firmware receives updates more frequently than Apple at this point.

Does atmosphere work on this or do we need to wait for an update?

 

[NotUsingAnAltAccount]

Still on 19.0.1 and thanks to Sphaira I'm playing all the new games. Newest updates are also not a problem.

My living grandfather (the green beret) would be fast to ask why you have such a slow-witted comment.

Speaking of dead, when will we get the Nintendo switch 3?

Version 20.4.0 sounds like a significant milestone. Can’t wait to see if there are hidden features or quality-of-life improvements waiting to be discovered.

 

[Reploid]

it's time to stop​

 

[NeoGranzon]

As always, we wait for the release of the new Atmosphere before updating.

 

[DeadSkullzJr]

Guess I'll be updating sometime later today. Thanks for the heads up!

Does atmosphere work on this or do we need to wait for an update?

NO, you always have to wait for a upgraded Atmosphère, sometimes is so simple as add the version number but sometimes Michael needs to make lots of changes.

@impeeza that's what i wrote in the previous post.

I just downloaded the 20.4.0 firmware, It uses the existing keys so no new PickLock is needed.

Sigpatches and SYS-Patch Sysmodule are the same so current versions works fine.

Bootlogos are exactly the same set of patches so no need to rebuild new ones.

@JK_ 's PNGShot will work fine because no new patches are needed.

NXThemesInstaller do not need to download new set of patches.

So we need just to wait for new Atmosphère and Hekate for update.

No news on https://switchbrew.org/wiki/FirmwareNews about the 20.4.0 firmware so we do not know yet which changes are included.

I didn't see it sorry.

everytime you update your switch. mario gain's an extra life don't it boy's and girl's shrooms are bad!!!!

Wow! Another boring update!

For me personally, the most exciting update they gave us for Switch enabled Bluetooth audio. Nothing else was memorable, and just anti-homebrew/anti-piracy updates to keep breaking Atmosphere.

"Web browser update"... If only we got an actually usable web browser in HorizonOS 21, but there's no way that's happening.
