Version History

Go here for details about the current version!

Obsolete Versions

Version 4.0.2 - April 7, 2021

  • New feature: "Countdown and Brick" (Mk3 only)
    • set a special PIN code, and when used, the Coldcard is immediately bricked while a normal-looking countdown for login is shown (default 1 hour). As an alternative to bricking, you can make it consume all but the final PIN attempt.
  • Enhancements to "Login Countdown" feature:
    • turning off the Coldcard will not clear the countdown, it continues on next power-up.
    • login countdown time delays are more accurate now.
    • Important: for the first login when firmware runs (immediately after upgrade), the login countdown delay, if you had previously enabled it, will not be enforced. However, the setting is then migrated to a new spot and takes effect going forward without any action needed.
  • Enhancement: Settings > Display Units: Select how to show Bitcoin amounts when displayed on-screen. Choices are BTC (default), mBTC (millibit), bits (aka uBTC), and sats (an integer).
  • Enhancement: Settings > Disable USB: New setting to disable USB port if your plan is air-gap only. Default remains USB port enabled.
  • Bugfix: Formating of larger SD Cards works again (FAT32 support).
  • Bugfix: Reject transactions whose outputs are greater than inputs.
  • Downgrades to v3 no longer supported.

Version 4.0.1 - March 29, 2021

  • Fixes security issue in v4.0.0. (3.x.x Unaffected)
  • Known issue: formatting of SD Card does not work and leads to a crash.

Version 4.0.0 - Mar 17, 2021

  • Major internal changes.
    • now using Bitcoin Core's "libsecp256k1" for all EC crypto operations
    • super fast pure-assembly AES256-CTR code makes USB communications faster
    • newly optimized SHA256 and SHA256(SHA256) code
    • all crypto and BIP-39 related code replaced
    • huge thanks to @switck for the new library!
  • Enhancement: During seed phrase import, after 23 words provided, Coldcard will calculate the correct checksum and show the valid choices for the last word (there will be 8 typically). This means you can pick seed words by drawing from a hat.
  • New feature: Secure Device Cloning. Using a MicroSD card, copy your Coldcard's secrets and settings to a blank Coldcard. Very quick and easy, uses public key encryption (Diffie-Hellman key exchange) and AES-256-CBC for the transfer.
  • Bugfix: CSV of addresses explorer export via Address Explorer, when account number was used, did not reflect the (non-zero) account number.
  • Enhancement: Reproducible builds! Checkout code, "cd stm32; make repro" should do it all.
  • Enhancement: Paper wallet feature restored as it was previously. Same cautions apply.
  • Enhancement: Inside encrypted backup files (7z), the cleartext filename is no longer fixed as ckcc-backup.txt. Instead it's a random word and number. Improves plausible deniability when backup files discovered.
  • Enhancement: Show a progress bar during slow parts of the login process.
  • Enhancement: Long menus, like the seed-word picking system, now wrap around from top/bottom, so you can get to Z by going up from A.
  • Limitation: Mk2 (older hardware, with less memory) may struggle with some of the new features, but can still run this firmware release... so you can clone it to your new Mk3!
  • HSM/CKBunker mode changes:
    • IMPORTANT: users with passwords will have to be reconstructed as hash algo has changed
    • when unlocking HSM mode from "boot to HSM mode" (using secret PIN immediately after bootup) the HSM policy is no longer removed automatically.
    • time limit to escape "boot to HSM" mode has doubled from 30 seconds to 1 minute.
  • Remaining GPL code has been removed, so license is now MIT+CC on everything.

Version 3.2.2 - Jan 14, 2021

  • Major Address Explorer enhancements! Thanks go to @switck for this major feature bump.
    • View sub-accounts as exported, just enter the account number.
    • Multisig wallet support! (Caveat: addresses are for verification purposes and never for direct use as deposit, so they are partially redacted)
    • Enter any custom derivation path, by entering numbers directly; for gurus.
    • Warning screen can be suppressed after reading first time (press 6)
    • Export of addresses now named "addresses.csv" not ".txt"
  • Bugfix: Disable a few more path derivation checks for "Skip Checks" for multisig compatibility. Handles error shown when working with previously-imported Spectre multisig wallets (ie. multisig.py: 891).
  • Bugfix: Generic wallet export (JSON) name for BIP-49 wallets changed from "p2wpkh-p2sh" to "p2sh-p2wpkh". Thanks @craigraw

Version 3.2.1 - Jan 8, 2021

  • Major Multisig improvements! If you are using multisig features, please backup your Coldcard before upgrade, just in case (but shouldn't be a problem).
    • Tracks derivation path for each co-signer and no longer assumes they all use a shared derivation path. Blocks multiple instances of same XFP in the wallet (not supported anymore, bad idea). Various displays updated to reflect derivation path change. Text file import: "Derivation:" line can be repeated, applies to all following xpubs.
    • Show Ypub/Zpub formated values from SLIP-132 when viewing details of wallet.
    • Standardize on "p2sh-p2wsh" nomenclature, rather than "p2wsh-p2sh", thanks to @humanumbrella. For airgaped multisig wallet creation, you must use same firmware verison on all Coldcards or this change can make trouble.
    • Address type (p2sh-p2wsh, p2sh, p2wsh) is captured from MS wallets created by PSBT file import.
    • Can now store multiple wallets involving same set of XFP values, if they have differing subkey paths and/or address formats.
    • New mode which disables certain multisig checks to assist bug compatibility.
  • Enhancement: Add support for signing Payjoin PSBT files based on BIP-78.
  • Enhancement: Promoted the address explorer to the main menu. It's useful! (credit to @matt_odell)
  • Bugfix: zero-length BIP-39 passphrase, when saved, would cause a crash when restore attempted. We recommend longer passphrases, but fixed the issue.
  • Enhancement: Move the "blockchain" setting deeper into the "Danger Zone" and add warning screen. This mitigates a concern raised by @benma (Marko Bencun) where an attacker could socially-engineer you to sign a transaction on Testnet, which corresponds to real UTXO being stolen. Only developers should be using Testnet.
  • Bugfix: Display of amounts could be incorrect by a few sats in final digits.
  • Bugfix: Incorrect digest method picked when P2SH-P2WSH incorrectly identified as plain P2SH.
  • Bugfix: Better error reporting when importing bogus multisig wallet files.
  • Enhancement: Files created on MicroSD will have date and time determined by the version of firmware that made them. Downstream systems might use this to know when the Coldcard should be upgraded, or which firmware version created the data. Idea from @sancoder
  • Enhancement: Show version of secure element, under Advanced > Upgrade > Show Version.
  • Enhancement: Improve 'None of the keys involved...' message to show XFP value actually found inside PSBT file.
  • Enhancement: "Invalid PSBT" errors are shown with more information now.
  • Paper Wallet features temporarily removed to free space; will return in future version.
  • License changed from GPL to MIT+CC on files for which the GPL doesn't apply.

Version 3.1.8 and 3.1.9 - Aug 6, 2020

  • Massive Enhancement: Optimized and improved drawing speed on screen, and responsiveness of keypad entry. You'll see some slight changes to login screen (centered now) and massive drawing performance improvements system-wide. Laggy and unresponsive keypad is no more!
  • New feature: New setting, "Delete PSBTs", will blank and securely erase input PSBT files when they are no longer needed. Also renames signed transaction to be (txid).txn (in hex)
  • Enhancement: The current XFP (xpub fingerprint) is shown on the "Ready To Sign" screen, if you have entered an BIP-39 Passphrase.
  • Enhancement: File names from SD Card are now shown in sorted order.
  • Enhancement: Can show the SHA256(file contents) for any file on SD Card. Use Advanced > MicroSD > List Files and pick your file. Thanks to B.O. for this idea.
  • Enhancement: Enable full BIP-85 support on older Mk2 hardware (derived entropy feature).
  • Enhancement: Minor text changes based on feedback from customers.
  • Enhancement: Two assertions promoted to text error messags related to bad PSBT files.
  • (v3.1.9) Enhancement: Very minor change so that login feels more responsive.
  • (v3.1.9) Bugfix: Small bug in production selftest. No other changes.

Version 3.1.7 - July 3, 2020

  • Enhancement: Detect, report and block the recently reported type of attack against BIP-143 (replay of segwit inputs) with an error message. No changes needed to your input PBST files. Will show errors similar to: "Input#0: Expected 15 but PSBT claims 5.00001 BTC"
  • Enhancement: When the Coldcard is finalizing the transaction, we show the TXID (hex transaction ID) of the transaction on the screen.
  • Enhancement: Export deterministically-derived entropy in the form of seed phrases (BIP-39), XPRV, private key (WIF), or hex digits using new BIP-85 standard. Useful for seeding other wallets from your Coldcard, so you don't need to backup "yet another" seed phrase. Derived values (all types) can be easly recreated from Coldcard later, or the backup of the Coldcard. Does not expose the Coldcard's master secret, should new wallet be compromised.
  • Bugfix: When scrambled keypad used with the login delay feature, the PIN-entry sequence was not scrambled after the forced delay was complete. Thanks to an anon customer for reporting this.
  • Bugfix: Scrambled keypad didn't change between PIN prefix and suffix.
  • Enhancement: QR Code rendering improved. Should be more readable in more cases. Faster.
  • Enhancement: View percent consumed of the settings flash space (just for debug)
  • Enhancement: New command to clear the UTXO history, in rare case of false positive.
  • (v3.1.6) Bugfix: Signing PSBT with finalization from MicroSD card, did not work. Error about "HexWriter" was shown, or "Assertion" error in 3.1.5.
  • (v3.1.7) Bugfix: Support longer bag numbers now in use at factory.

Version 3.1.3 - April 30, 2020

  • Enhancement: Save your BIP-39 passphrases, encrypted, onto a specific SDCard, if desired. Passphrases are encrypted with AES-256 (CTR mode) using a key derived from the master secret and hash of the serial number of the SDCard. You cannot copy the file to another card. To use this feature, press (1) after you've successfully entered your passphrase. 'Restore Saved' menu item will appear at top of passphrase-entry menu, when correctly-encrypted file is detected.
  • Enhancement: Export a generic JSON skeleton file, not aligned with any particular desktop/mobile wallet, but useful for any such integrations. Includes XPUB (and associated data) needed for P2PKH, P2WPKH (segwit) and P2WPKH-P2SH wallets, which conform to BIP-44, BIP-84, and BIP-49 respectively. Thanks to @craigraw the idea.
  • Enhancement: when signing a text file from MicroSD card, if you specify a derivation path that starts with m/84'/... indicating that you are following BIP-84 for segwit addresses, the resulting signature will be formatted as P2WPKH in Bech32.
  • Minor code cleanups and optimizations.

Version 3.1.2 - Feb 27, 2020

  • Enhancement: New setting to enable a scrambled numeric keypad during PIN login.
  • Enhancement: Press 4 when viewing a payment address (triggered by USB command) to see the QR code on-screen (Mk3 only).
  • Enhancement: Can enter non-zero account numbers when exporting wallet files for Electrum and Bitcoin Core. This makes importing seeds from other systems easier and safer.
  • Enhancement: Dims the display when entering HSM Mode.
  • Bugfix: Trust PSBT setting (for multisig wallets) was being ignored. Thanks to @CasaHODL for reporting this.
  • Bugfix: XPUB values volunteered in the global section of a PSBT for single-signer files would cause errors (but ok in multisig). Coldcard will now handle this, although it doesn't need them.
  • Bugfix: 3.1.1 had a bug which broke the new "non-zero account export" feature.

Version 3.1.0 - Feb 20, 2020

  • HSM (Hardware Security Module) mode: give Coldcard spending rules, including whitelisted addresses, velocity limits, subsets of authorizing users ... and Coldcard can sign with no human present. Requires companion software to setup (ckbunker or ckcc-protocol), and disabled by default, with multi-step on-screen confirmation required to enable. Mk3 only.
  • Enhancement: New "user management" menu. Advanced > User Management shows a menu with usernames, some details and a 'delete user' command. USB commands must be used to create user accounts and they are only used to authenticate txn approvals in HSM mode.
  • Enhancement: PSBT transaction can be "visualized" over USB, meaning you can view what the Coldcard will show on the screen during approval process, as text, downloaded over USB. That text can be signed (always with root key) to prove authenticity.
  • Enhancement: Sending large PSBT files, and firmware upgrades over USB should be a little faster.
  • IMPORTANT: This release is NOT COMPATIBLE with Mk1 hardware. It will brick Mk1 Coldcards.

Version 3.1.0 - Feb 20, 2020

Requires companion software to setup (ckbunker or ckcc-protocol), and disabled by default, with multi-step on-screen confirmation required to enable. Mk3 only.
  • Enhancement: New "user management" menu. Advanced > User Management shows a menu with usernames, some details and a 'delete user' command. USB commands must be used to create user accounts and they are only used to authenticate txn approvals in HSM mode.
  • Enhancement: PSBT transaction can be "visualized" over USB, meaning you can view what the Coldcard will show on the screen during approval process, as text, downloaded over USB. That text can be signed (always with root key) to prove authenticity.
  • Enhancement: Sending large PSBT files, and firmware upgrades over USB should be a little faster.
  • IMPORTANT: This release is NOT COMPATIBLE with Mk1 hardware. It will brick Mk1 Coldcards.

Version 3.0.6 - Dec 19, 2019

  • Security Bugfix: Fixed a multisig PSBT-tampering issue, that could allow a MitM to steal funds. Please upgrade ASAP.
  • Enhancement: Sign a text file from MicroSD. Input file must have extension .TXT and contain a single line of text. Signing-key subpath can be provided on the second line.
  • Enhancement: Now shows the change outputs of the transaction during signing process. This additional data can be ignored, but it is useful for those who wish to verify all parts of the new transaction.
  • Enhancement: PSBT files on MicroSD can now be provided in base64 or hex encodings. Resulting (signed) PSBT will be written in same encoding as the input PSBT.
  • Bugfix: crashed on entry into the Address Explorer (some users, sometimes).
  • Bugfix: add blank line between addresses shown if sending to multiple destinations.
  • Bugfix: multisig outputs were not checked to see if they are change (would have been shown as regular outputs), if the PSBT did not have XPUB data in globals section.
  • NOTE: This is the final version to support Mk1 hardware.

Version 3.0.5 - Nov 25, 2019

  • Address explorer can show QR code for any address (Mk3 only). Press 4 to view. Once shown, press 1 to invert image, and 5/8 for next address. Successful scanning requires the best phone camera, and some patience, due to limited screen size.
  • Export a command file for Bitcoin Core to create an air-gapped, watch-only wallet. Requires v0.18 or higher of Bitcoin Core. docs/bitcoin-core-usage.md has been updated. Thanks to @Sjors for creating this new feature!
  • Paper Wallets! Creates random private key (or use your own dice for entropy), completely unrelated to your seed words, and saves deposit address and private key (WIF format) into a text file on MicroSD. If you have a Mk3, it will also add a QR code inside the text file, and if you provide a special PDF-like template file (example in paperwallet.pdf) then it will superimpose the QR codes into the template, and save the resulting ready-to-print PDF to MicroSD. CAUTION: Paper wallets carry MANY RISKS and should only be used for SMALL AMOUNTS.
  • Adds a "Format Card" command for erasing MicroSD contents and reformatting (FAT32).
  • Bugfix: Idle-timeout setting should only take effect after the login countdown. Thanks to @aoeui21 for reporting this.

Version 3.0.3 - Nov 6, 2019

  • Add "Login Countdown" feature: once enabled, you must enter you PIN correctly, and then wait out a forced delay (of minutes/hours/days) while a count down is shown on-screen. Then enter your PIN correctly, a second time, to get in. You must provide continuous power to the Coldcard during this entire period! Go to Settings > "Login Countdown" for the time intervals to pick from. Thanks to @JurrienSaelens for this feature suggestion.
  • Nickname feature: Enter a short text name for your personal Coldcard. It's displayed at startup time before PIN is entered. Try it out in Settings > "Set Nickname"
  • Bugfix: Adding a second signature (multisig) onto a PSBT already signed by a different Coldcard could fail with "psbt.py:351" error.
Version 3.0.2 - Nov 1, 2019
  • New command in Danger Zone menu to view the seed words on-screen, so you can make another on-paper backup as needed.
  • Robustness: Analyse paths used for change outputs and show a warning if they are not similar in structure to the inputs of that same transaction. These are imperfect heuristics and if you receive a false positive, or are doing weird things that don't suit the rules below, please send an example PSBT to support and we'll see if we can handle it better:
    • same derivation path length
    • shared pattern of hardened/not path components
    • 2nd-last position is one or zero (change/not change convention)
    • last position within 200 units of highest value observed on inputs
  • Robustness: Improve checking on key path derivations when we encounter them as text.
    • accept 10h and 10p as if they are 10' (alternative syntax)
    • define a max depth (12) for all derivations
    • thanks to @TheCharlatan
  • Security Improvement: during secure logout, wipe entire contents of serial flash, which might contain PSBT, signed or unsigned (for more privacy, deniability)
Version 3.0.1 - Oct 10, 2019
  • MARK3 SUPPORT!
    • Adds support for Mark 3 hardware: larger CPU and better secure element (608)
    • Many invisible changes inside the secure element (ATECC608A).
    • Mark3 will brick itself after 13 incorrect PIN codes, so lots of warning are shown.
  • Contains all the features of 2.1.6 and still works on Mk1 and Mk2 hardware
  • Visual changes to login process (rounded boxes, different prompts, more warnings)
  • New USB command to report if Bitcoin versus Testnet setting is in effect.
Major changes in v2.x.x:
  • NEW for 2.1.6: "Address Explorer": view receive addresses on the screen of the Coldcard, so you can be certain your funds are going to the right place. Can also write first 250 addresses onto the SDCard in a simple text (CSV) format. Special thanks go to @hodlwave for creating this feature.
  • Major release with Multisig support!
    • New menu under: Settings > Multisig Wallets
    • Lists all imported M-of-N wallets already setup
    • Export, import for air-gapped creation
    • Related settings and more
  • Broad change: extended public key finger (XFP) values used to be shown in the wrong endian (byte swapped), and prefixed with 0x to indicate they were a number. In fact, they are a byte string and should be shown in network order. Everywhere you might be used to seeing your XFP value has been switched, so 0x0f056943 becomes 4369050F (all caps, no 0x prefix). Affected areas include:
    • BIP-39 password confirmation screen
    • Advanced > View Identity screen
    • Electrum skeleton wallet export (label of wallet)
    • Dump public data file (text in file header)
    • xfp command in ckcc CLI helper (can show opposite endian, if needed)
  • New feature: Create seed words from D6 dice rolls (v2.1.1):
    • under "Import Existing > Dice Rolls"
    • just keep pressing 1 - 6 as you roll. At least 99 rolls are required for 256-bit security
    • seed is sha256(over all rolls, as ascii string)
    • normal seed words are shown so you can write those down instead of the rolls
    • can also "mix in" dice rolls: after Coldcard picks the seed words and shows them, press 4 and you can then do some dice rolls (as many or as few as desired) and get a new set of words, which adds those rolls as additional entropy.
  • Export skeleton wallets for Wasabi Wallet https://wasabiwallet.io/ to support air-gapped use.
  • Summary file (public.txt) has been reworked to include more XPUB values and a warning about using addresses your blockchain-monitoring wallet might not be ready for.
  • When BIP-39 passphrase is given over USB, and approved, the new XFP is shown on-screen for reference.
  • Use with Electrum will require our updated plugin changes.

Changes in version 2.1.6:

  • NEW: "Address Explorer" feature (see above)
  • Bugfix: Improve error message shown when depth of XPUB of multisig cosigner conflicts with path details provided in PSBT or USB 'show address' command.
  • Bugfix: When we don't know derivation paths for a multisig wallet, or when all do not share a common path-prefix, don't show anything.

Changes in version 2.1.5:

  • Bugfix: Changes to redeem vs. witness script content in PSBTs. Affects multisig change outputs, primarily.
  • Bugfix: Import of multisig wallet from xpubs in PSBT could fail if attempted from SD Card.
  • Bugfix: Improved message shown if import of multsig wallet was refused during PSBT signing.

Changes in version 2.1.4:

  • Bugfix: For multisig change outputs, many cases were incorrected flagged as fraudulent.

Changes in version 2.1.3:

  • Visual change: unknown components of multsig co-signer derivation paths used to be shown as m/?/?/0/1 but will now be shown as m/_/_/0/1. The blank indicates better that we can't prove what is in that spot, not that we don't know what value is claimed.
  • Bugfix: Some backup files would hit an error during restore (random, less than 6%). Those existing backup files will be read correctly by this new version of firmware.
  • Bugfix: P2SH-P2WPKH change outputs incorrectly flagged as fraudulent (regression from v1.1.0)
  • Bugfix: Wanted redeem script, but should be witness script for P2WSH change outputs.

Changes in version 2.1.2:

  • Add extra warning screen added about forgetting your PIN.
  • Remove warning screen about Testnet vs Mainnet.
  • Bugfix: Change for XFP endian display introduced in 2.0.0 didn't actually correct endian display and it was still showing values in LE32. Correctly corrected now.
    • now showing both values in "Advanced > View Identity screen".
    • some matching changes to ckcc-protocol (CLI tool)
    • when making multisig wallets in airgap mode, you must use latest firmware on all the units
  • Bugfix: Error messages would sometimes disappear off the screen quickly. Now they stay up until OK pressed. Text of certain messages also improved.
  • Bugfix: Show a nicer message when given a PSBT with corrupted UTXO values.
  • Bugfix: Block access to multisig menu when no seed phrase yet defined.
  • Bugfix: Any command on multisig menu that used the MicroSD card would crash, if card was not present.
  • Bugfix: When offline multisig signing sometimes tried to finalize PSBT, but we can't.
  • Bugfix: For multi-pass-multisig signing, handle filenames better (end in -part, not -signed).
Versions v2.0.3 – 2.0.4

2019-05-13T1631-v2.0.4-coldcard.dfu built May 13, 2019.

  • Transaction signing speed improved by about 3X.
  • Will warn if miner's fee is over 5% of txn amount (was 1% before). Hard limit remains 10% (configurable, can be disabled completely).
  • Robustness: Tighten stack-depth checking, increase heap size, shuffle some memory.
  • Bugfix: Transactions with more than 10 outputs were not summarized correctly.
  • Bugfix: Consolidating transactions that move UTXO within same wallet are shown better.
  • Bugfix: Better recovery from too-complex transaction errors.
  • "Don't forget your PIN" warning message is more bold now.
  • (in 2.0.4) Bugfix: Clearing duress PIN would lead to a error screen.
  • (in 2.0.4) Bugfix: Advanced > "Lock Down Seed" command didn't work correctly.
  • (in 2.0.4) Bugfix: Importing seed words manually didn't work on second try (thanks @duck1123)
Versions 2.0.0 – 2.0.2
  • BIP-39 Passphrase support: enter up to 100 characters to create new wallets from your existing seed words. Each is a completely independant wallet to Electrum and PSBT files, so please make note of the extended master fingerprint (eight hex digits).
  • Support for Mark2 hardware, with membrane keypad replacing touch interface.
  • Adds activity light during MicroSD card read/write (Mk2 only)
  • New command: "Lock down seed" which converts BIP-39 seed words and passphrase into the master xprv and saves that as new wallet secret. Locks in the passphrase, deletes seed words.
  • New bootrom, version 1.2.1 with Mk2 hardware support and improved one-wire bus MitM defences.
  • Bugfix: extra keypress occurs during certain interactions involving key repeat.
  • (in 2.0.1) bugfix: underscore/space indicator shown on Settings > Idle Timeout menu
  • (in 2.0.2) Page up/down on long text displays with 7/9 keys
  • (in 2.0.2) Public summary file now includes extended master key fingerprint near top of file.
  • (in 2.0.2) Bugfix: signing larger transactions could fail due to lack of memory
Version 1.1.0

2018-11-26T1403-v1.1.0-coldcard.dfu built Nov 26, 2018.

Release Notes
  • Allow setting max network fee to a number of possible levels, or disable it (was previously fixed to 10%). Thanks to @crwatkins for this suggestion.

  • Touch improvements: two new setting, which are between the old 'Least Sensitive' and 'Most Sensitive' settings. New menu text.

  • Touch sensitivity preference is applied before login, so PIN entry is easier.

  • Although we do not use the bech32_decode() function recently found to have an buffer overflow bug, we've included the fix into our fork of the affected library. This change, and the original bug, does not affect the Coldcard firmware in any way.

  • Correctly include witness data in transactions when signing based on witness UTXO data (thanks to @SomberNight)

  • Bugfix: Fix divide-by-zero if transaction sends zero amount out (only possible if network fee equals 100% of inputs).

Version 1.0.2

2018-09-11T1428-v1.0.2-coldcard.dfu built Sep 11th, 2018.

Release Notes

    • yprv/zprv keys can now be imported
    • public.txt file includes both SLIP-132 and BIP-32 values where needed (segwit cases)
    • test cases added to match
  • Can create Electrum skeleton wallet for Segwit Native and Segwit P2SH now.
    • caveat: the plugin is not ready yet for P2SH/Segwit, but Segwit native is fine
  • Improvements in 'public.txt' output:
    • add SLIP-132 values where we can
    • correct names when used for Litecoin
