COLDCARD Q v0.0.6-beta: Source Code Is Now Public
COLDCARD Q is the higher-end COLDCARD that comes with a full QWERTY keyboard, a larger LCD screen, a real QR scanner and more. The Q uses exactly the same security model as the Mk4 COLDCARD, with dual multi-vendor secure elements.

What's new
- bugfix: randomize keys for PIN entry
- when picking files, we just skip to showing you the files options (or picking the single winner) rather than talking about it first.
- BIP-39 passphrase process completely streamlined
- batch signing now offered when we see two or more signable PSBT's on the card
- bugfix: can now reformat SD card in B slot
- move away from `44'` (prime) for hardened derivation paths, in favour of `44h`; both accepted for input, but we are going to display `44h` style going forward.
- bugfix: (QR) or other double-wide chars would be garbled if half off right edge
- cleanups, bugfixes
