#COLDCARD Firmware Update

# Shared Mk4 & Q

New Features:

📳 PushTX: once enabled with a service provider's URL, you can tap the COLDCARD and your phone will open a webpage that transmits your freshly-signed transaction onto the blockchain. See Settings > NFC Push Tx to enable and select service provider, or your own webpage. More at pushtx org. You can also use this to broadcast any transaction found on the MicroSD card (See Tools > NFC Tools > Push Transaction).

🕵️‍♂️ Transaction Output Explorer: allows viewing all output details for larger txn (10+ output, 20+ change) before signing. Offered for large transactions only because we are already showing all the details for typical transactions.

🏷️ Setting to enable always showing XFP as first item in home menu.

Enhancement:

⏫ When signing, show sum of outgoing value at top. Always show number of inputs/outputs and total change value.
⏫ Add Sign PSBT shortcut to NFC Tools menu
⏫ Stricter p2sh-p2wpkh validation checks.
⏫ Show master XFP of BIP-85 derived wallet in story before activation. Only words and extended private key cases.
⏫ Add Theya option to Export Wallet
⏫ Mention the need to remove old duress wallets before locking down temporary seed.

Bugfix:

👨‍🔧 Fix PSBTv2 PSBT_GLOBAL_TX_MODIFIABLE parsing.
👨‍🔧 Decrypting Tapsigner backup failed even for correct key.
👨‍🔧 Clear any pending keystrokes before PSBT approval screen.
👨‍🔧 Display max 20 change outputs in when signing, and max 10 of largest outputs, and offer the Transaction Output Explorer if more to be seen.
👨‍🔧 Calculate progress bar correctly in Address Explorer after first page.
👨‍🔧 Search also Wrapped Segwit single sig addresses if P2SH address provided, not just multisig (multisig has precedence for P2SH addresses)
👨‍🔧 Address search would not find addresses for non-zero account numbers that had been exported but not yet seen in a PSBT.

## Mk4 Specific Changes 5.3.2 - 2024-06-26

👨‍🔧 Displaying change address in Address Explorer fails if NFC and Vdisk not enabled.

## Q Specific Changes 1.2.2Q - 2024-06-26

⏫ Coldcard multisg export/import format detected in Scan Any QR Code.
⏫ Support newer-version QR scanner modules.
👨‍🔧 Exporting BIP-85 derived entropy via NFC was offered even when NFC disabled, leading to a Yikes error.
