PyOTA v2.0.4

⚠️ This release contains a few changes that may be backwards-incompatible, depending on how your application is configured. Check the Backwards-Incompatible Changes section for more information! ⚠️

Backwards-Incompatible Changes

Renamed CLI Command

The iota-cli command has been renamed to pyota-cli, to avoid conflicts with the cli-app project.

If PyOTA is already installed, the iota-cli command will continue to work (the pyota-cli command will be installed alongside it). However, if you install PyOTA into a new virtualenv, it will not install the iota-cli command, only pyota-cli!

Deprecated Methods

The following methods now emit a DeprecationWarning when invoked. Depending on how your application is configured, these warnings may be converted into exceptions.

  • TryteString.as_bytes() (use TryteString.encode() instead).
  • TryteString.as_string() (use TryteString.decode() instead).
  • TryteString.from_string() (use TryteString.from_unicode() instead).

To resolve the DeprecationWarning, replace usages of the deprecated methods with the replacement versions as noted above.

Tip: After making this change, your application will no longer be compatible with PyOTA <= 2.0.4; it is recommended that you also add pyota >= 2.0.4 to your project's setup.py or requirements.txt file!

If your application does not use any of the methods listed above, no action is required.

Changelog

  • (#121) Added is_promotable and promote_transaction API methods (thanks @scottbelden!).
  • (#38) Added is_reattachable API method (thanks @jinnerbichler!).

  • (#111) add_neighbor and remove_neighbor now also accept URIs that start with tcp:// (thanks @danielfaust for reporting!).
  • (#92) Added offset and length arguments to PyCurl methods (thanks @mlouielu!).
  • (#90) Renamed the following methods:
    • TryteString.as_bytes() => TryteString.encode()
    • TryteString.as_string() => TryteString.decode()
    • TryteString.from_string() => TryteString.from_unicode()
  • (#130) Fixed incorrect type in get_tips response (thanks @za-uz for reporting!)
  • (#120) Fixed references to "standard" API in the documentation (thanks @rpitonak!).
  • Added helpers namespace to Iota (thanks @scottbelden!).
  • Added missing fields in transaction documentation (thanks @GalRogozinski!).
  • Made examples/send_transfer.py easier to read (thanks @maeck70!).
  • Added new setuptools extra "test-runner", to install detox.
    • Added more information about running unit tests to README.rst.
  • Added metadata check to the build process and fixed invalid syntax in README.rst.
  • Fixed incorrect type hint for find_transaction_objects.

**⚠️ This release contains a few changes that may be backwards-incompatible, depending on how your application is configured.  Check the Backwards-Incompatible Changes section for more information! ⚠️**

## Backwards-Incompatible Changes
### Renamed CLI Command
The `iota-cli` command has been renamed to `pyota-cli`, to avoid conflicts with the [cli-app](https://github.com/iotaledger/cli-app/blob/v1.0.8/package.json#L31) project.

If PyOTA is already installed, the `iota-cli` command will continue to work (the `pyota-cli` command will be installed alongside it).  However, if you install PyOTA into a new virtualenv, it will **not** install the `iota-cli` command, only `pyota-cli`!

### Deprecated Methods
The following methods now emit a `DeprecationWarning` when invoked.  Depending on how your application is configured, these warnings may be converted into exceptions.

* `TryteString.as_bytes()` (use `TryteString.encode()` instead).
* `TryteString.as_string()` (use `TryteString.decode()` instead).
* `TryteString.from_string()` (use `TryteString.from_unicode()` instead).

To resolve the `DeprecationWarning`, replace usages of the deprecated methods with the replacement versions as noted above.

**Tip: After making this change, your application will no longer be compatible with PyOTA < 2.0.4; it is recommended that you also add `pyota >= 2.0.4` to your project's `setup.py` or `requirements.txt` file!**

If your application does not use any of the methods listed above, no action is required.

PyOTA v2.0.0

⚠️ This release contains several changes that are not backwards compatible with the previous version. Please review the Backwards-Incompatible Changes before upgrading! ⚠️

Backwards-Incompatible Changes

  • PyOTA now requires pip v9 or later.
    • If you are unable to install the latest version of PyOTA, run pip install --upgrade pip first.
  • [#39] PyOTA now requires requests 2.4.1 or later.
    • If you install PyOTA using pip, you do not need to do anything special; dependencies will be updated automatically when you run pip install --upgrade pyota.
    • If you install PyOTA by cloning the GitHub repo, you must re-run pip install . to install missing dependencies.
  • [#61] PyOTA now uses the new Kerl and Curl-P-81 algorithms.
    • This change introduces a dependency on the pysha3 library. See previous bullet point for installation instructions.
    • These changes are coordinated with the Tangle snapshot created on 21 August, 2017.
    • If your application maintains a local database of keys/addresses, you may need to regenerate them.
    • More information:
    • Thanks @alon-e for assistance with PyKerl implementation!
  • [#51] Removed address caches for security reasons.
  • Reversed the behavior of the head_to_tail parameter in Bundle.as_tryte_strings.
    • Previously, setting head_to_tail=True would return transactions in reverse order (and mutatis mutandis), which is incorrect. Now it returns the transactions in the correct order.
  • Digest now requires that its length be a multiple of 81 trytes.
  • Removed iota symlink at the top level of the package structure, renamed src to iota.
    • This only impacts developers who have cloned the repository; if you install PyOTA via pip, this will not affect you.

New Features

  • [#10] Implemented multisig support.
  • [#28] Added support for address security levels.
  • [#67] Added support for attachment timestamps (thanks @normpad!).
  • [#53] Reduced default min_weight_magnitude (thanks @johngrantuk!):
    • New mainnet value: 14
    • New testnet value: 9
  • [#18] Added convert_value_to_standard_unit (thanks @vynes!).
  • Installing via pip now automatically installs iota-cli app into env path.
    • This replaces examples/repl.py.
  • Added support for PyOTA-CCurl extension.
    This is an optional C extension that improves the performance of Curl-P-81 significantly (speedups of 60x are common).
    • Thanks @elk for making the extension compatible with Python 2!

Enhancements and Bugfixes

  • TryteString (and subclasses) now support creating new instances from unicode values. It is no longer necessary to convert values into byte strings first.
  • [#44] Seed.random now generates 81-tryte seeds by default.
    • Previously, it was generating 82-tryte seeds.
  • [#42] Transaction.from_tryte_string now accepts optional hash argument (thanks @alon-e for reporting!).
  • [#41] Fixed error when invoking help(api) in the REPL script.
  • Address.with_valid_checksum now also copies balance, key_index and security_level.
  • [#47] Added example script showing proof-of-concept for integrating with JS MAM library.
    • A Python implementation of MAM is coming; for now it is necessary to use the JS library.
  • [#63] Fixed conflict when importing PyOTA in a Django project (thanks @labovich!).
  • Improved PyCurl performance by ~7%.
  • Split out the transactions module into its own package.
    • Existing imports should still work; please file an issue on the PyOTA Issue Tracker if you notice any broken imports.
  • Made JSON representations of certain objects more comprehensive.
  • Added IPython repr integrations.
  • Improved documentation, fixed a few minor issues.
  • Fixed incorrect behavior of examples/address_generator.py (thanks @ivoscc!).
  • Fixed node URI in examples/sandbox.py.
  • [#34] Added example script demonstrating how to route PoW to local node (thanks @johngrantuk)!.
  • [#31] Added example script demonstrating how to send IOTAs to an address (thanks @johngrantuk!).
  • PyOTA now ships universal wheels.
  • Travis CI now only deploys tagged releases to PyPI.
    • After v2.0.0, master will only contain the latest production release of PyOTA.
  • Added contributor guide.
  • Removed unnecessary dependencies from Python 3 installs. If you use Python 3, you may uninstall the following libraries:
    • mock
    • typing

Huge thanks to @normpad and @alon-e for helping test the v2.0.0 beta and making sure it is stable for production release!

Additional thanks to the following individuals for contributing code and identifying issues during the development of PyOTA v2:

    * **If you install PyOTA by cloning the GitHub repo, you must re-run `pip install .` to install missing dependencies.**
* [#61] PyOTA now uses the new Kerl and Curl-P-81 algorithms.
    * These changes are coordinated with the Tangle snapshot created on 21 August, 2017.
    * **If your application maintains a local database of keys/addresses, you may need to regenerate them.**
    * More information:
        * https://forum.iota.org/t/snapshot-public-validation-22-09-2017/4256
    * Thanks @alon-e for assistance with PyKerl implementation!

### New Features
* [#53] Reduced default `min_weight_magnitude` (thanks @johngrantuk!):
    * New mainnet value: 14
    * New testnet value: 9
* Removed unnecessary dependencies from Python 3 installs.
    * If you use Python 3, you may uninstall the following libraries:
        * `mock`
        * `typing`

### Bugfixes
* [#63] Fixed conflict when importing PyOTA in a Django project (thanks @labovich!).

## Misc
* [#34] Added example script demonstrating how to route PoW to local node (thanks @johngrantuk)!.
* [#31] Added example script demonstrating how to send IOTAs to an address (thanks @johngrantuk!).
* PyOTA now ships universal wheels.
* Fixed incorrect PEP-484 type hints.
* Improved docstrings and comments.

Pre-release

PyOTA v1.2.0-beta1

⚠️ This is pre-release software! Do not use in production contexts! ⚠️

⚠️ This release contains several changes that are not backwards compatible with the previous version. Please review the Backwards-Incompatible Changes before upgrading! ⚠️

Backwards-Incompatible Changes

  • [#51] Removed address caches.
  • [#39] PyOTA now requires requests 2.4.1 or later.
  • Reversed the behavior of the head_to_tail parameter in Bundle.as_tryte_strings.
    • Previously, setting head_to_tail=True would return transactions in reverse order (and mutatis mutandis), which is incorrect. Now it returns the transactions in the correct order.
  • Digest now requires that its length be a multiple of 81 trytes.
  • Removed iota symlink at the top level of the package structure, renamed src to iota.
    • This only impacts developers who have cloned the repository; if you install PyOTA via pip, this will not affect you.

New Features

  • [#10] Implemented multisig support.
  • [#28] Added support for address security levels.
  • [#18] Added convert_value_to_standard_unit (thanks @vynes!).
  • Installing via pip now automatically installs iota-cli app into env path.
    • This replaces examples/repl.py.
  • Added support for pyota-ccurl extension (Python 3 only, for the moment).

Enhancements and Bugfixes

  • TryteString (and subclasses) now support creating new instances from unicode values.
    • It is no longer necessary to convert values into byte strings first.
  • [#44] Seed.random now generates 81-tryte seeds by default.
    • Previously, it was generating 82-tryte seeds.
  • [#42] Transaction.from_tryte_string now accepts optional hash argument (thanks @alon-e for reporting!).
  • [#41] Fixed error when invoking help(api) in the REPL script.
  • Address.with_valid_checksum now also copies balance, key_index and security_level.
  • No longer installs unnecessary dependencies on Python 3.
    • If you are using Python 3, you may uninstall the typing and mock libraries.
  • [#47] Added example script showing proof-of-concept for integrating with JS MAM library.
    • A Python implementation of MAM is coming; for now it is necessary to use the JS library.
  • Improved PyCurl performance by ~7%.
  • Split out the transactions module into its own package.
    • Existing imports should still work; please file an issue on the PyOTA Issue Tracker if you notice any broken imports.
  • Made JSON representations of certain objects more comprehensive.
  • Added IPython repr integrations.
  • Improved documentation, fixed a few minor issues.
  • Fixed incorrect behavior of examples/address_generator.py (thanks @ivoscc!).
  • Fixed node URI in examples/sandbox.py.
  • Added contributor guide.
