Changelog

The changelog records significant changes to both the firmware and the bootloader. Since the bootloader has a separate release cycle and existing customers cannot upgrade their bootloader, its changes are recorded separately.

Firmware

[Unreleased]

  • Bitcoin: warn if the transaction fee is higher than 10% of the coins sent
  • ETH Testnets: add Goerli and remove deprecated Rinkeby and Ropsten

9.13.1

  • Fix bug introduced in 9.13.0: remove double cancel confirmation in the 'Restore from recovery words' workflow

9.13.0

  • Bitcoin: allow displaying BTC values in the 'sat' unit
  • Allow skipping the microSD card backup in favor of backing up using the recovery words
  • Allow arbitrary input sequence numbers (fixes compatibility with Taproot transactions in Sparrow wallet)
  • The BackupData.length field is now obsolete and always set to 0
  • Port remaining protobuf code to Rust, remove the C nanopb protobuf dependency.
  • Ethereum: replace ERC20 token names with their unit codes in the receive screen
  • SetPassword now returns the UserAbort error instead of the Generic error if the user cancelled

9.12.0

  • Ethereum: add support for EIP-712 structured data signing
  • UI: add a 1px padding for left/right-aligned text for better visibility

9.11.0

  • Add SSD1312 driver for new OLED screens

9.10.0 [2022-03-10]

  • Bitcoin: add support for BIP-86: receive to taproot addresses and sign transactions with taproot inputs
  • Ethereum: add support for the Binance Smart Chain, Optimism, Polygon, Fantom Opera and Arbitrum One networks

9.9.1 [2022-02-07]

  • Cardano: support sending to legacy Byron addresses
  • Cardano: disallow duplicate token keys in an output

9.9.0 [released 2022-01-10]

  • Support sending to taproot addresses
  • ListBackups: ported to Rust
  • Confirm restore from microSD before setting a device password
  • Cardano: allow transactions with a zero TTL value
  • Cardano: add support for sending tokens
  • Protobuf: rename BTCSignOutputRequest.hash to BTCSignOutputRequest.payload

9.7.0 [released 2021-09-06]

  • Allow mainnet keypaths (m/44'/60'/0'/0/*) Rinkeby and Ropsten, and testnet keypaths (m/44'/1'/0'/0/*) for Ethereum mainnet
  • Display granular error codes when unlock fails unexpectedly
  • Remove RandomNumber API endpoint

9.6.0 [released 2021-05-20]

  • Attempt to fix flaky SD behavior
  • Add securechip_model to DeviceInfo: ATECCC608A or ATECC608B.
  • Added reboot purpose for clearer UX: "Proceed to upgrade?" vs. "Go to startup settings?"
  • Allow creation of 128 bit seeds (12 BIP39 recovery words)
  • Increase maximum number of registered multisig accounts from 10 to 25.

9.5.0 [released 2021-03-10]
