omemo_dart/CHANGELOG.md

0.1.0

• Initial version
• Implement the Double Ratchet, X3DH and OMEMO specific bits
• Add a Blind-Trust-Before-Verification TrustManager
• Supported OMEMO version: 0.8.3

0.1.3

• Fix bug with the Double Ratchet causing only the initial message to be decryptable
• Expose getDeviceMap as a developer usable function

0.2.0

• Add convenience functions getDeviceId and getDeviceBundle
• Creating a new ratchet with an id for which we already have a ratchet will now overwrite the old ratchet
• Ratchet now carry an "acknowledged" attribute

0.2.1

• Add isRatchetAcknowledged
• Ratchets that are created due to accepting a kex are now unacknowledged

0.3.0

• Implement enabling and disabling ratchets via the TrustManager interface
• Fix deserialization of the various objects
• Remove the BTBV TrustManager's loadState method. Just use the constructor
• Allow removing all ratchets for a given Jid
• If an error occurs while decrypting the message, the ratchet will now be reset to its prior state
• Fix a bug within the Varint encoding function. This should fix some occasional UnknownSignedPrekeyExceptions
• Remove OmemoSessionManager's toJson and fromJson. Use toJsonWithoutSessions and fromJsonWithoutSessions. Restoring sessions is not out-of-scope for that function

0.3.1

• Fix a bug that caused the device's id to change when replacing a OPK
• Every decryption failure now causes the ratchet to be restored to a pre-decryption state
• Add method to get the device's fingerprint

0.4.0

• Deprecate OmemoSessionManager. Use OmemoManager instead.
• Implement queued access to the ratchets inside the OmemoManager.
• Implement heartbeat messages.
• [BREAKING] Rename Device to OmemoDevice.

0.4.1

• Fix fetching the current device and building a ratchet session with it when encrypting for our own JID

0.4.2

• Fix removeAllRatchets not removing, well, all ratchets. In fact, it did not remove any ratchet.

0.4.3

• Fix bug that causes ratchets to be unable to decrypt anything after receiving a heartbeat with a completely new session

0.5.0

This version is a complete rework of omemo_dart!

• Removed events from OmemoManager
• Removed OmemoSessionManager
• Removed serialization/deserialization code
• Replace exceptions with errors inside a result type
• Ratchets and trust data is now loaded and cached on demand
• Accessing the trust manager must happen via withTrustManager
• Overriding the base implementations is replaced by providing callback functions

0.5.1

• Remove added and replaced from the data passed to the CommitRatchetsCallback
• Added a list of newly added and replaced ratchets to the encryption and decryption results. This is useful for displaying messages like "Contact added a new device"
