1.2.0b1

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.
