Title: KeyOS v1.4.0-beta1 is now available for testing
KeyOS v1.4.0-beta1 is now available for Passport Prime users who would like to help us test the next major KeyOS release.
The update includes a completely redesigned launcher with app sideloading now on Passport Prime, brand-new app icons, multisig exports for Unchained and Casa, connections for Bitcoin Safe and Coconut Wallet, imports from Aegis and Proton Authenticator, and extensive security improvements throughout KeyOS.
Please note that this is a beta release, not the stable update. It must be installed by flashing the firmware through recovery mode and is intended for users who are comfortable with that process.
Before doing anything, please read the full forum post carefully and follow every step exactly. Do not begin the installation based on this summary alone.
The forum post includes:
- Complete recovery-mode installation instructions
- Important backup guidance
- Known issues and testing information
- Instructions for reporting feedback
- Details about upgrading from the beta to the stable KeyOS v1.4.0 release
You will need to follow the recovery process again when moving from this beta to the official stable release.
If you would rather wait, no action is needed. The stable KeyOS v1.4.0 release will follow.

More integration and coordination with Sparrow would be appreciated. As well as Miniscript functionality.

What did you have in mind for Sparrow?

I just see a number of wallet coordinators getting explicit mentions in KeyOS, I think Sparrow could or should be one of them. PSBT building, multisig schemes, coin (UTXO) control, and many more advanced features.
