Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog.

At the moment, the project does not adhere to Semantic Versioning. That is expected to change with version 1.0.

0.11.0 - 2018-12-06

Incompatible changes

  • removed support for Python 3.3 and 3.4
  • major refactor of TrezorClient and UI handling. Implementers must now provide a "UI" object instead of overriding callbacks #307, #314
  • protobuf classes now use a get_fields() method instead of FIELDS field #312
  • all methods on TrezorClient class are now in separate modules and take a TrezorClient instance as argument #276
  • mixin classes are also removed, you are not supposed to extend TrezorClient anymore
  • TrezorClientDebugLink was moved to debuglink module
  • changed signature of trezorlib.btc.sign_tx
  • @field decorator was replaced by an argument to @expect

Added

  • trezorlib now has a hardcoded check preventing use of outdated firmware versions #283
  • Ripple support #286
  • Zencash support #287
  • Cardano support #300
  • Ontology support #301
  • Tezos support #302
  • Capricoin support #325
  • limited Monero support (can only get address/watch key, monerowallet is required for signing)
  • support for input flow in tests makes it easier to control complex UI workflows #314
  • protobuf.dict_to_proto can create a protobuf instance from a plain dict
  • support for smarter methods in trezord 2.0.25 and up
  • support for seedless setup
  • trezorctl: firmware handling is greatly improved #304, #308
  • trezorctl: Bitcoin-like signing flow is more user-friendly
  • tx_api now supports Blockbook backend servers

Changed

  • better reporting for debuglink expected messages
  • replaced Ed25519 module with a cleaner, optimized version
  • further reorganization of transports makes them more robust when dependencies are missing
  • codebase now follows Black code style
  • in Qt modules, Qt5 is imported first #315
  • TxApiInsight is just TxApi
  • device.reset and device.recover now have reasonable defaults for all arguments
  • protobuf classes are no longer part of the source distribution and must be compiled locally #284
  • Stellar: addresses are always strings

Removed

  • set_tx_api method on TrezorClient is replaced by an argument for sign_tx
  • caching functionality of TxApi was moved to a separate test-support class
  • Stellar: public key methods removed
  • EncryptMessage and DecryptMessage actions are gone

Fixed:

  • TrezorClient can now detect when a HID device is removed and a different one is plugged in on the same path
  • trezorctl now works with Click 7.0 and considers "_" and "-" as same in command names #314
  • bash completion fixed
  • Stellar: several bugs in the XDR parser were fixed

0.10.2 - 2018-06-21

Added

  • stellar_get_address and _public_key functions support show_display parameter
  • trezorctl: stellar_get_address and _public_key commands for the respective functionality

Removed

  • trezorctl: list_coins is removed because we no longer parse the relevant protobuf field (and newer Trezor firmwares don't send it) #277

Fixed

  • test support module was not included in the release, so code relying on the deprecated ckd_public module would fail #280

0.10.1 - 2018-06-11

Fixed

  • previous release fails to build on Windows #274

0.10.0 - 2018-06-08

Added

  • Lisk support #197
  • Stellar support #167, #268
  • Wanchain support #230
  • support for "auto lock delay" feature
  • TrezorClient takes an additional argument state that allows reusing the previously entered passphrase #241
  • USB transports mention udev rules in exception messages #245
  • log.enable_debug_output function turns on wire logging, instead of having to use TrezorClientVerbose
  • BIP32 paths now support 123h in addition to 123' to indicate hardening
  • trezorctl: -p now supports prefix search for device path #226
  • trezorctl: smarter handling of firmware updates #242, #269

Changed

  • reorganized transports and moved into their own transport submodule
  • protobuf messages and coins info is now regenerated at build time from the trezor-common repository #248
  • renamed ed25519raw to _ed25519 to indicate its privateness
  • renamed ed25519cosi to cosi and expanded its API
  • protobuf messages are now logged through Python's logging facility instead of custom printing through VerboseWireMixin
  • client.format_protobuf is moved to protobuf.format_message
  • tools.Hash is renamed to tools.btc_hash
  • coins module coins_txapi is renamed to tx_api.
    coins_slip44 is renamed to slip44.
  • build: stricter flake8 checks

  • tests: unified finding test device, while respecting TREZOR_PATH env variable.
  • tests: auto-skip appropriately marked tests based on Trezor device version
  • tests: only show wire output when run with -v
  • tests: allow running xfailed tests selectively based on pytest.ini
  • docs: updated README with clearer install instructions #185
