Changes

New Device Support: Embed Fire

This device shares similarities with the WonderMV but stands out with its larger 2.4" touchscreen.

New Device Support: WonderK PRO

From the wonderful land of Korea, a new creation arrives: the WonderK PRO. Created by an entrepreneur who loves the Krux project, the WonderK follows in the footsteps of the WonderMV, but boasts a larger 2.8" display and better USB-C compatibility. Computer simulator for the WonderK device is also included.

Loading a Descriptor Sets Wallet Attributes

Loading a descriptor is now a quick way to set wallet attributes, as all necessary information is extracted automatically. This eliminates the need for manual configuration and ensures consistency with your coordinator wallet.

Changed BIP39 Passphrase Validation

Krux now displays a warning instead of blocking QR-encoded passphrases that contain non-ASCII characters. Users are encouraged to use QR codes containing only ASCII passphrases or non-ASCII that have already been normalized to NFKD.

Easier to Scan UR QR Codes

Exported Uniform Resource (UR) QR codes, a widely adopted standard for exchanging PSBTs, now use uppercase data to reduce QR density, improving scan reliability without increasing the number of frames.
