- Enhancement: Scan any QR and report if it is part of a wallet this Coldcard knows the key for. Includes #MultiSig and #SingleSig wallets.
- searches up to the first 1528 addresses (external and change addresses)
- stores data as it goes to accelerate future uses
- worst case, it can take up to 2 minutes to rule out an address, but after that it is fast!
- Enhancement: #CalculatorLoginMode. When enabled, the usual PIN entry screen is replaced with a functional calculator. Enter your PIN as `12-12` or `12 12` to get it. To verify anti-phishing words, use `12-`.
- Bugfix: Key right of L was giving back quote, should have been single-quote. SYM+E for back quote.
- Bugfix: Constant `AFC_BECH32M` incorrectly set `AFC_WRAPPED` and `AFC_BECH32`.
- Bugfix: Base64 PSBT via QR was not properly decoded.
- Bugfix: Fix inability to activate Duress Wallet as temporary seed when master seed is 12 words.
- Bugfix: Switch to BBQr for larger data exports at a new lower size threshold.
