I wonder when the decision to rebrand the OSes was made. This is on an iPad running 26.

Perhaps it was just being held close internally.

I wonder when they decided to name it iOS 26, since for the AirPods Pro beta firmware it says: „Turn on pre-release beta updates to test new AirPods features in iOS 19.0.“

I love that you can toggle the beta firmware through settings on iOS26 without needing to enable developer mode through Xcode. At least I was able to with an iPhone 15 Pro Max and AirPods Pro 2 USB-C.
*looks like you need to be on developer not appleseed*

Wait, version "8A5279d"?

Why not AirPodsOS 26?
I guess they do not feel the need to name it as an OS. These numbers are used for all their system software, eg. macOS 26 beta 1 is called 25A5279m. Notice that it starts with 25, I believe this is a tidbit from the Darwin OS the OS that all the "Apple OS's" are based upon, and uses the major version number from the year it is released. Darwin OS version number would be the version number like internal Windows version, and iOS 26, macOS 26 etc. will all be on Darwin OS 25. So now they will be a version "behind". The 8 in AirPods Pro signals that it is the 8 major version of the firmware for the AirPods Pro 2.

Sorry, I should have added "on iOS26". I have updated my post.

It's in the AirPods settings. At least it shows on my AirPods Pro 2 USB-C on an iPhone 15 Pro Max running iOS26.
Toggle is not shown on my AirPods Pro Max Lightning, must only show when a beta firmware is available or only on certain AirPods.
I have 26 running on a 15 pro max also. Only difference is that I have the older AirPods Pro 2, not usb c. Weird. Keep seeing that dialogue in screenshots and I can’t get it to show up.

Might be worth reporting issues updating or the menu option not showing with the feedback app just in case.
Make sure you’re on developer beta option and not appleseed.
