History-Q.md

See ChangeLog.md for more recent changes, these are historic versions

1.2.3Q - 2024-07-05

• New Feature: 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 https://pushtx.org. You can also use this to broadcast any transaction found on the MicroSD card (See Tools > NFC Tools > Push Transaction).

• New Feature: 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.

• New Feature: 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.

• Enhancement: Add Sign PSBT shortcut to NFC Tools menu

• Enhancement: Stricter p2sh-p2wpkh validation checks.

• Enhancement: Show master XFP of BIP-85 derived wallet in story before activation. Only words and extended private key cases.

• Enhancement: Add Theya option to Export Wallet

• Enhancement: Mention the need to remove old duress wallets before locking down temporary seed.

• Bugfix: Fix PSBTv2 PSBT_GLOBAL_TX_MODIFIABLE parsing.

• Bugfix: Decrypting Tapsigner backup failed even for correct key.

• Bugfix: Clear any pending keystrokes before PSBT approval screen.

• Bugfix: 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.

• Bugfix: Calculate progress bar correctly in Address Explorer after first page.

• Bugfix: Search also Wrapped Segwit single sig addresses if P2SH address provided, not just multisig (multisig has precedence for P2SH addresses)

• Bugfix: Address search would not find addresses for non-zero account numbers that had been exported but not yet seen in a PSBT.

• (v5.3.3/1.2.3Q) Bugfix: Trying to set custom URL for NFC push transaction caused yikes error.

• Enhancement: Coldcard multisg export/import format detected in Scan Any QR Code.

• Enhancement: Support newer-version QR scanner modules.

• Bugfix: Exporting BIP-85 derived entropy via NFC was offered even when NFC disabled, leading to a Yikes error.

• Bugfix: Properly clear LCD screen after simple QR code is shown

1.2.1Q - 2024-05-09

• Important Bugfix: Already imported multisig wallets would show errors when signing. This was caused by our internal change in key path notation from 84' (prime) to 84h (hardened).

• Enhancement: Add Nunchuk and Zeus options to Export Wallet

• Enhancement: View Identity shows temporary seed active at the top

• Enhancement: Can specify start index for address explorer export and browsing

• Enhancement: Allow unlimited index for BIP-85 derivations. Must be enabled first in Danger Zone

• Change: Passphrase menu item is no longer offered if BIP39 passphrase already in use. Use Restore Master with ability to keep or purge current passphrase wallet settings.

• Change: Removed ability to add passphrase to master seed if active temporary seed.

• Change: Wipe LFS during Lock Down Seed and Destroy Seed

• Bugfix: Do not allow non-ascii or ascii non-printable characters in multisig wallet name

• Bugfix: Brick Me option for If Wrong PIN caused yikes.

• Bugfix: Properly handle and finalize framing error response in USB protocol.

• Bugfix: Handle ZeroSecretException for BIP39 passphrase calculation when on temporary seed without master secret

• Bugfix: Saving passphrase on SD Card caused a freeze that required reboot

• Bugfix: Properly verify signed armored message with regtest address

• Bugfix: Create ownership file when generating addresses export CSV

• Recovery SD Card image building moved into its own repo: github.com/Coldcard/recovery-images

• Bugfix: Reload trick pins before checking for active duress wallet.

• Enhancement: Allow export of multisig XPUBs via BBQr

• Enhancement: Import multisig via QR/BBQr - both legacy COLDCARD export and descriptors supported

• Enhancement: Status bar text is sharper now

• Enhancement: Added ability to write signed PSBT/txn to lower (B) SD slot when both cards inserted

• Bugfix: Fullscreen display of v23 and v24 QRs were too dense and hard to read

• Bugfix: Battery idle timeout also considers last progress bar update

• Bugfix: Allow Send Password (keystrokes) of capital letters of alphabet

• Bugfix: Pressing SYM+SHIFT was toggling CAPS continuously. Now toggles once only

• Bugfix: Restrict keys that can be pressed during seed entry after final word inserted

1.1.0Q - 2024-04-02

• Enhancement: Scan any QR and report if it is part of a wallet this Coldcard knows the key for. Includes Multisig and single sig 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: Calculator login mode. 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.
  • Generally, won't show tiny QR anymore with 1:1 pixels.
  • Sparrow wallet export will always be BBQr now.
  • Most other exports fit into a reasonable single QR.
• Bugfix: fixed Type Passwords a.k.a emulated keystrokes
• Bugfix: Yikes when using BIP39 passphrase with temporary seed without master seed set.
• Tweak: Default idle timeout when on battery, was reduced to 10 minutes from 30.
• Tweak: Cursor movements wrap around if menu is longer than screen height.
• Tweak: Force default HW settings (USB,NFC,VDisk OFF) after clone/backup is restored.

• bugfix: very obscure bug in low level code could cause txid to be miscalculated if all the conditions occured just right
• Animated BBQr are shown as chunkier QR's to make them easier for other devices to scan.
• Supports QR export from Wallet Exports: will be either text file (U) or JSON (J) BBQr sequence, but only if it cannot fit into normal single QR.

0.0.6Q - 2024-02-22

• 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.
