UNRELEASED

  • Expose new methods OlmMachine::set_room_settings and OlmMachine::get_room_settings. (#3042)

  • Add new properties session_rotation_period and session_rotation_period_msgs to store::RoomSettings. (#3042)

  • Fix bug which caused SecretStorageKey to incorrectly reject secret storage keys whose metadata lacked check fields. (#3046)

  • Add new API Device::encrypt_event_raw that allows to encrypt an event to a specific device. (#3091)

0.7.0

  • Add method to mark a list of inbound group sessions as backed up: CryptoStore::mark_inbound_group_sessions_as_backed_up

  • OlmMachine::toggle_room_key_forwarding is replaced by two separate methods:

    • OlmMachine::set_room_key_requests_enabled, which controls whether outgoing room key requests are enabled, and:

    • OlmMachine::set_room_key_forwarding_enabled, which controls whether we automatically reply to incoming room key requests.

    OlmMachine::is_room_key_forwarding_enabled is updated to return the setting of OlmMachine::set_room_key_forwarding_enabled, while OlmMachine::are_room_key_requests_enabled is added to return the setting of OlmMachine::set_room_key_requests_enabled.

    (#2902)

  • Improve performance of share_room_key. (#2862)

  • get_missing_sessions: Don't block waiting for /keys/query requests on blacklisted servers, and improve performance. (#2845)

  • Generalize olm::Session::encrypt to accept any value implementing Serialize for the value parameter, instead of specifically serde_json::Value. Note that references to Serialize-implementing types themselves implement Serialize.

  • Change the argument to OlmMachine::receive_sync_changes to be an EncryptionSyncChanges struct packing all the arguments instead of many single arguments. The new next_batch_token field there should be the next_batch value read from the latest sync response.

  • Handle missing devices in /keys/claim responses. (#2805)

  • Add the higher level decryption method decrypt_session_data to the BackupDecryptionKey type.

  • Add a higher level method to create signatures for the backup info. The OlmMachine::backup_machine()::sign_backup() method can be used to add signatures to a RoomKeyBackupInfo.

  • Remove the backups_v1 feature, backups support is now enabled by default.

  • Use the Signatures type as the return value for the MegolmV1BackupKey::signatures() method.

  • Add two new methods to import room keys, OlmMachine::store()::import_exported_room_keys() for file exports and OlmMachine::backup_machine()::import_backed_up_room_keys() for backups. The OlmMachine::import_room_keys() method is now deprecated.

  • The parameter order of OlmMachine::encrypt_room_event_raw and OutboundGroupSession::encrypt has changed, content is now last

    • The parameter type of content has also changed, from serde_json::Value to &Raw<AnyMessageLikeEventContent>

  • Change the return value of bootstrap_cross_signing so it returns an extra keys upload request. The three requests must be sent in the order they appear in the return tuple.

  • Stop logging large quantities of data about the Store during olm decryption.

  • Remove spurious "Unknown outgoing secret request" warning which was logged for every outgoing secret request.

  • Clean up the logging of to-device messages in share_room_key.

  • Expose new OlmMachine::get_room_event_encryption_info method.

  • Add support for secret storage.

  • Add initial support for MSC3814 - dehydrated devices.

  • Mark our OwnUserIdentity as verified if we successfully import the matching private keys.

  • The OlmMachine::export_cross_signing_keys() method now returns a Result. This removes an unwrap() from the codebase.

  • Add support for the hkdf-hmac-sha256.v2 SAS message authentication code.

  • Ensure that the correct short authentication strings are used when accepting a SAS verification with the Sas::accept() method.

  • Add a new optional message-ids feature which adds a unique ID to the content of m.room.encrypted event contents which get sent out.

  • Disable the automatic-key-forwarding feature by default.

  • Add a new variant to the VerificationRequestState enum called Transitioned. This enum variant is used when a VerificationRequest transitions into a concrete Verification object. The concrete Verification object is given as associated data in the Transitioned enum variant.

  • Replace the libolm backup encryption code with a native Rust version. This adds WASM support to the backups_v1 feature.

  • Add new API store::Store::room_keys_received_stream to provide updates of room keys being received.

  • Add new method identities::device::Device::first_time_seen_ts that allows to get a local timestamp of when the device was first seen by the sdk (in seconds since epoch).

  • When rejecting a key-verification request over to-device messages, send the m.key.verification.cancel to the device that made the request, rather than broadcasting to all devices.

  • Expose VerificationRequest::time_remaining.

  • For verification-via-emojis, return the word "Aeroplane" rather than "Airplane", for consistency with the Matrix spec.

  • Fix handling of SAS verification start events once we have shown a QR code.

  • Fix a bug which could cause generated one-time-keys not to be persisted.

  • Fix parsing error for POST /_matrix/client/v3/keys/signatures/upload responses generated by Synapse.

  • Add new API OlmMachine::query_keys_for_users for generating out-of-band key queries.

  • Rename "recovery key" to "backup decryption key" to avoid confusion with the secret-storage key which is also known as a recovery key.

    This affects the matrix_sdk_crypto::store::RecoveryKey struct itself (now renamed to BackupDecryptionKey, as well as BackupMachine::save_recovery_key (now save_decryption_key).

  • Change the returned success value type of BackupMachine::backup from OutgoingRequest to (OwnedTransactionId, KeysBackupRequest).
