## [0.10.0] - unreleased

### Added
- Lisk support #197

- `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`

- 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
- build: split requirements to separate files
- 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 `xfail`ed tests selectively based on `pytest.ini`
- docs: updated README with clearer install instructions #185
- docs: switched changelog to Keep a Changelog format #94

### Deprecated
- `ckd_public` is only maintained in `tests.support` submodule and considered private
- `TrezorClient.expand_path` is moved to plain function `tools.parse_path`
- `TrezorDevice` is deprecated in favor of `transport.enumerate_devices` and `transport.get_transport`
- XPUB-related handling in `tools` is slated for removal

### Removed
- most Python 2 compatibility constructs are gone #229
- `TrezorClientVerbose` and `VerboseWireMixin` is removed
- specific `tx_api.TxApi*` classes removed in favor of `coins.tx_api`
- `client.PRIME_DERIVATION_FLAG` is removed in favor of `tools.HARDENED_FLAG` and `tools.H_()`
- hard dependency on Ethereum libraries and HIDAPI is changed into extras that need to be
  specified explicitly. Require `trezor[hidapi]` or `trezor[ethereum]` to get them.

### Fixed
- WebUSB enumeration returning bad devices on Windows 10 #223
- `sign_tx` operation sending empty address string #237
- Wrongly formatted Ethereum signatures #236
- protobuf layer would wrongly encode signed integers #249, #250
- protobuf pretty-printing broken on Python 3.4 #256

  - add pretty-printing of features and protobuf debug dumps (fixes #199)
  - support `TREZOR_PATH` environment variable to preselect a Trezor device.

### Removed
- gradually dropping Python 2 compatibility (pypi package will now be marked as Python 3 only)
