Foundation Passport v2.1.0: P2TR, BIP-85, Nostr, SeedQR Export & More

New features

• "Backported our firmware from Batch 2 to Founder’s Edition, bringing firmware parity for all of our early supporters."
• "Added support for sending to Taproot (“P2TR”) addresses."
• "Added a “Key Manager” extension for enabling advanced functionalities. You can use Key Manager to generate and export:
  
  - BIP 85 child seeds, allowing you to backup only Passport’s seed and be able to recover other wallets directly from Passport’s seed
  
  - Nostr private keys, allowing you to securely generate, easily backup, and recover your Nostr private keys directly from Passport or Passport’s seed.
  
  - Simply display your Nostr key as a QR code and login directly to your favorite app with a single scan. No more copy-pasting private keys."

"Thanks to greenart7c3 you can use this today in Amethyst, a fantastic Android Nostr app!"

• "Please note that if you export keys as QR codes, you should be careful what you scan them with! Apps like Google Camera will often open the content of the QR code in your default search engine, exposing that key to Google etc."
• "Any keys you set up will be automatically backed up to microSD in an encrypted format, making recovery a breeze."
• "Added support for exporting BIP 85 seeds via SeedQR. Exports are possible via SeedQR and Compact SeedQR. Importing SeedQR is coming soon."
• "Allow users to display their PIN when entering it by pressing the “UP” key during PIN entry."

Improvements

• "Cleaned up our C code, optimizing our firmware and giving more space for amazing new features."
• "Make “Erase Now” no longer the default selected option when you enter the erase screen, just to be sure an itchy trigger finger won’t accidentally erase your Passport."
• "Ensure Founder’s Edition properly communicates its device information to Envoy."
• "Passport will now indicate that it’s 30 seconds away from auto-shutdown by dimming its screen."
• "Removed support for 18-word seed phrases as they are very, very rarely used."

Bug fixes

• "Improved error handling and prevention in displaying transaction info."
• "Better handling of errors caused by other wallets’ multisig config formats."
• "Fixed a display issue with the screen brightness icon."
• "Fixed an issue that would prevent signing of PSBTs in sub-directories on microSD."
