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.

• 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

Added

• trezorlib now has a hardcoded check preventing use of outdated firmware versions #283

• Zencash support #287
• Cardano support #300
• Ontology support #301

• protobuf.dict_to_proto can create a protobuf instance from a plain dict
• support for smarter methods in trezord 2.0.25 and up

• 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

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
