Changelog

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

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.0.0] - Unreleased

Changed

  • Complete rewrite of the library (and dependencies) to use asynchronous and (strictly) typed Python 3.
  • Support for different versions of XEP-0384 via separate backend packages.
  • Mostly following Keep a Changelog now (except for the date format).

0.14.0 - 12th of March, 2022

Changed

  • Adjusted signature of the SessionManager.encryptRatchetForwardingMessage method to accept exactly one bare JID + device id pair
  • Updated the license in the setup.py, which was desync with the LICENSE file
  • Adjusted the copyright year

Removed

  • Removed Python 3.4 from the list of supported Python versions
  • Removed some mentions of Python 2 from the README

0.13.0 - 15th of December 2021

Added

  • Added a method to retrieve the receiving chain length of a single session form the SessionManager

Changed

  • The storage interface has been modified to use asyncio coroutines instead of callbacks.
  • All methods of the session manager that returned promises previously have been replaced with equivalent asyncio coroutines.

Removed

  • Dropped Python 2 support and removed a bit of Python 2 compatibility clutter
  • Removed synchronous APIs
  • Removed thread-based promise implementation in favor of asyncio futures and coroutines

0.12.0 - 28th of March, 2020

Changed

  • The JSONFileStorage now encodes JIDs using hashes, to avoid various issues regarding the file system. WARNING, THERE ARE KNOWN ISSUES WITH THIS VERSION OF THE STORAGE IMPLEMENTATION.
  • Sending 12 byte IVs instead of 16 now.
  • SessionManager.encryptKeyTransportMessage now receives the optional plaintext as a parameter directly, instead of using a callback to encrypt external data. If the plaintext is omitted, a shared secret is returned that can be used for purposes external to this library.
  • Switched to MIT license with the agreement of all contributors!

Fixed

  • Fixed the way key transport messages are sent and received to be compatible with other implementations.

0.11.0 - 13th of December, 2019

Added

  • Added a new method resetTrust, which allows going back to the trust level undecided.

Changed

  • Merged the trust and distrust methods into setTrust.
  • Storage.storeTrust must now be able to handle the value None for the trust parameter.

Removed

  • Removed the SessionManagerAsyncIO, in preparation for the big Python 3 update coming soon™.

Fixed

  • Fixed a bug in the SessionManager, where the contents of a parameter (passed by reference) were modified.

0.10.5 - 21st of July, 2019

Fixed

  • Fixed two bugs in the JSONFileStorage implementation.
  • Fixed a type issue in the __str__ of the TrustException.
  • Fixed a rare bug where sessions uncapable of encrypting messages would be stored.

0.10.4 - 1st of February, 2019

Added

  • Added an implementation of the storage using a simple directory structure and JSON files.

Changed

  • RatchetForwardingMessages do not require the recipient to be trusted any more, as they contain no user-generated content. See #22 for information.
  • Renamed UntrustedException to TrustException and added a fourth field problem to get the type of problem (untrusted vs. undecided).

0.10.3 - 29th of December, 2018

Added

  • Added a method for requesting trust information from the storage at bulk. This can be overridden for better performance.
  • Added a method for requesting sessions from the storage at bulk. This can be overridden for better performance.
  • Added a public method to delete an existing session. This is useful to recover from broken sessions.
  • Added a public method to retrieve a list of all managed JIDs.
  • Added a stresstest, mostly to test recursion depth.

Changed

  • Turned the changelog upside-down, so that the first entry is the newest.
  • Modified no_coroutine in the promise lib to use a loop instead of recursion.
  • Modified the promise constructor to run promises in threads.

0.10.2 - 29th of December, 2018

Added

  • Added methods to retrieve trust information from the SessionManager: getTrustForDevice and getTrustForJID.

Changed

  • Introduced an exception hierarchy to allow for more fine-grained exception catching and type checking.
  • Most exceptions now implement __str__ to generate human-readable messages.

Fixed

  • Fixed a bug that tried to instantiate an object of the wrong class from serialized data.

0.10.1 - 27th of December, 2018

Added

  • Added CHANGELOG.

Changed

  • Upon serialization the current library version is added to the serialized structures, to allow for seamless updates in the future.
