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


## 1.3.5Q - 2025-11-03

- Enhancement: Address format guessing changed away from using PSBT XPUB's derivation paths.
  Now based on witness/redeem script of first PSBT input instead.
- Enhancement: Show master XFP of backup secret and ask user for confirmation before loading backup.
- Enhancement: Show firmware version added to hobbled Advanced/Tools menu.
- Bugfix: Exiting text input of Custom Backup Password caused yikes.
- Bugfix: Temporary seeds in SSSP mode were not able to update block height.
- Enhancement: Show backup filename at the top of the screen during backup password entry.


## 1.3.4Q - 2025-09-30

- Spending policies for "Single Signers" adds new spending policy options:
    - limit your Coldcard so it refuses to sign transactions that are "too big"
    - require 2FA authentication before signing any transaction (NFC+web)
    - velocity limits can restrict how often new transactions can be signed
    - see `docs/spending-policy.md` for more details
    - "Enable HSM" and "User Management" have moved into `Advanced > Spending Policy`.
    - Old "CCC" feature has been renamed and moved into that menu as well: "Co-Sign Multisig"
- Added `Bull Bitcoin` export to `Export Wallet` menu.
- Enhancement: Added warning for zero value outputs if not `OP_RETURN`.
- Enhancement: Show QR codes of output addresses in transaction output explorer. Explorer is
  now offered for transactions of all sizes, not just complex ones.
- Enhancement: Added file rename, when listing contents of SD card.
- Enhancement: Added ability to restore Coldcard backup via USB (needs latest of ckcc version)
- Enhancement: Address ownership allows to specify particular multisig wallet in which to search,
  if `wallet` query parameter is provided via trivial extension to
  [BIP-21](https://github.com/bitcoin/bips/blob/master/bip-0021.mediawiki).
  Example: `tb1q4d67p7stxml3kdudrgkg5mgaxsrgzcqzjrrj4gg62nxtvnsnvqjsxjkej0?wallet=Haystack`
- Bugfix: If all change outputs have `nValue=0`, they were not shown in UX.
- Bugfix: Disallow negative input/output amounts in PSBT.
- Bugfix: Fix filesystem initialization after Wipe LFS or Destroy Seed.
- Bugfix: Fix MicroSD selftest code.

- Bugfix: Ownership check failing to find addresses near max (~760), needed to be re-run to succeed
- (Q only) Enhancement: Enters "forever calculator" mode when Q would otherwise be electronic waste
  (ie. after 13 PIN failures). Always enabled, regardless of "login calculator" setting.
- (Q only) Bugfix: Correct line positioning when 24 seed words displayed.


## 1.3.3Q - 2025-05-14

- Enhancement: Text word-wrap done more carefully so never cuts off any text, and yet
  doesn't waste space.
- Bugfix: `Add current tmp` option, which could be shown in `Seed Vault` menu under
  specific circumstances, would corrupt master settings if selected.
- Bugfix: PUSHDATA2 in bitcoin script caused yikes.
- Bugfix: Warning for unknown scripts was not shown at the top of the signing story.

- Bugfix: Do not allow to teleport PSBTs from SD card when CC has no secrets.
- Bugfix: Calculator login mode: added "rand()" command, removed support
  for variables/assignments.


## 1.3.2Q - 2025-04-16

- Feature: Key Teleport -- Easily and securely move seed phrases, secure notes/passwords,
  multisig PSBT files, and even full Coldcard backups, between two Q using QR codes
  and/or NFC with helper website. See protocol spec in
  [docs/key-teleport.md](https://github.com/Coldcard/firmware/blob/master/docs/key-teleport.md)
    - can send master seed (words, xprv), anything held in seed vault, secure notes/passwords 
      (singular, or all) and PSBT involved in a multisig to the other co-signers
    - full COLDCARD backup is possible as well, but receiver must be "unseeded" Q for best result
    - ECDH to create session key for AES-256-CTR, with another layer of AES-256-CTR using a
      short password (stretched by PBKDF2-SHA512) inside
    - receiver shows sender a (simple) QR and a numeric code; sender replies with larger BBQr
      and 8-char password
- Enhancement: Always choose the biggest possible display size for QR
- Bugfix: Only BBQr is allowed to export Coldcard, Core, and pretty descriptor
- Huge new feature: CCC - ColdCard Cosign
    - COLDCARD holds a key in a 2-of-3 multisig, in addition to the normal signing key it has.
    - it applies a spending policy like an HSM:
        - velocity and magnitude limits
        - whitelisted destination addresses
        - 2FA authentication using phone app ([RFC 6238](https://www.rfc-editor.org/rfc/rfc6238))
    - but will sign its part of a transaction automatically if those condition are met, 
      giving you 2 keys of the multisig and control over the funds
    - spending policy can be exceeded with help of the other co-signer (3rd key), when needed
    - cannot view or change the CCC spending policy once set, policy violations are not explained
    - existing multisig wallets can be used by importing the spending-policy-controlled key
- New Feature: Multisig transactions are finalized. Allows use of [PushTX](https://pushtx.org/)
  with multisig wallets.  Read more [here](https://github.com/Coldcard/firmware/blob/master/docs/limitations.md#p2sh--multisig)
- New Feature: Signing artifacts re-export to various media. Now you have the option of
  exporting the signing products (transaction/PSBT) to different media than the original source.
  Incoming PSBT over QR can be signed and saved to SD card if desired.
- New Feature: Multisig export files are signed now. Read more [here](https://github.com/Coldcard/firmware/blob/master/docs/msg-signing.md#signed-exports)
- Enhancement: NFC export usability upgrade: NFC keeps exporting until CANCEL/X is pressed
- Enhancement: Add `Bitcoin Safe` option to `Export Wallet`
- Enhancement: 10% performance improvement in USB upload speed for large files
- Bugfix: Do not allow change Main PIN to same value already used as Trick PIN, even if
  Trick PIN is hidden.
- Bugfix: Fix stuck progress bar under `Receiving...` after a USB communications failure
- Bugfix: Showing derivation path in Address Explorer for root key (m) showed double slash (//)
- Bugfix: Can restore developer backup with custom password other than 12 words format
- Bugfix: Virtual Disk auto mode ignores already signed PSBTs (with "-signed" in file name)
- Bugfix: Virtual Disk auto mode stuck on "Reading..." screen sometimes
- Bugfix: Finalization of foreign inputs from partial signatures. Thanks Christian Uebber
- Bugfix: Temporary seed from COLDCARD backup failed to load stored multisig wallets
- Change: `Destroy Seed` also removes all Trick PINs from SE2.
- Change: `Lock Down Seed` requires pressing confirm key (4) to execute

## 1.3.1Q - 2025-02-13

- New signing features:
    - Sign message from note text, or password note
    - JSON message signing. Use JSON object to pass data to sign in form
        `{"msg":"<required msg>","subpath":"<optional sp>","addr_fmt": "<optional af>"}`
    - Sign message with key resulting from positive ownership check. Press (0) and
      enter or scan message text to be signed.
    - Sign message with key selected from Address Explorer Custom Path menu. Press (2) and
      enter or scan message text to be signed.
- Enhancement: New address display format improves address verification on screen (groups of 4).
- Deltamode enhancements:
    - Hide Secure Notes & Passwords in Deltamode. Wipe seed if notes menu accessed. 
    - Hide Seed Vault in Deltamode. Wipe seed if Seed Vault menu accessed. 
    - Catch more DeltaMode cases in XOR submenus. Thanks [@dmonakhov](https://github.com/dmonakhov)
- Enhancement: Add ability to switch between BIP-32 xpub, and obsolete SLIP-132 format
  in `Export XPUB`
- Enhancement: Use the fact that master seed cannot be used as ephemeral seed, to show message 
  about successful master seed verification.
- Enhancement: Allow devs to override backup password.
- Enhancement: Add option to show/export full multisg addresses without censorship. Enable
  in `Settings > Multisig Wallets > Full Address View`.
- Enhancement: If derivation path is omitted during message signing, derivation path
  default is no longer root (m), instead it is based on requested address format
  (`m/44h/0h/0h/0/0` for p2pkh, and `m/84h/0h/0h/0/0` for p2wpkh). Conversely,
  if address format is not provided but subpath derivation starts with:
  `m/84h/...` or `m/49h/...`, then p2wpkh or p2sh-p2wpkh respectively, is used.
- Bugfix: Sometimes see a struck screen after _Verifying..._ in boot up sequence.
  On Q, result is blank screen, on Mk4, result is three-dots screen.
- Bugfix: Do not allow to enable/disable Seed Vault feature when in temporary seed mode.
- Bugfix: Bless Firmware causes hanging progress bar.
- Bugfix: Prevent yikes in ownership search.

- Enhancement: Sign/Verify Address in Sparrow via QR
- Enhancement: Sign scanned Simple Text by pressing (0). Next screen query information
  about which key to use.
- Enhancement: Add option to "Sort By Title" in Secure Notes and Passwords. Thanks to
  [@MTRitchey](https://x.com/MTRitchey) for suggestion.
- Bugfix: Properly re-draw status bar after Restore Master on COLDCARD without master seed.


## 1.3.0Q - 2024-09-12

## 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`).

    - if less than 12 frames would result, uses simpliest QR that can fit on 
      screen at 3x or 2x size. Result is easier to scan BBQr's.
    - progress bar along bottom drawn differently
    - in some cases, the status bar area (at top) will be used to show QR
