Added

  • #1639: Introduce PublicStorageProvider trait to independently allow for the storage of PublicGroup instances.
  • #1641: Extend the PublicGroup API with add_proposal(), remove_proposal(), and queued_proposals().

  • #1638: Remove serde from PublicGroup. PublicGroup::load() becomes public to load a group from the storage provider.
  • #1642: OpenMlsProvider is no longer required for the PublicGroup API. The PublicGroup API now uses the PublicStorageProvider trait directly. ProcessMessageError::InvalidSignature was removed and replaced with ValidationError::InvalidSignature.

Removed

Fixed

  • #1641: Fixed missing storage of queued proposals & clearing of the queued proposals.

0.6.0-pre.1 (2024-07-22)

Added

  • #1629: Add add_members_without_update function to MlsGroup to allow the creation of add-only commits
  • #1506: Add StagedWelcome and StagedCoreWelcome to make joining a group staged in order to inspect the Welcome message. This was followed up with PR #1533 to adjust the API.
  • #1516: Add MlsGroup::clear_pending_proposals to the public API; this allows users to clear a group's internal ProposalStore
  • #1565: Add new StorageProvider trait to the openmls_traits crate.

Changed

  • #1464: Add builder pattern for MlsGroup; split MlsGroupJoinConfig into MlsGroupCreateConfig and MlsGroupJoinConfig
  • #1473: Allow setting group context extensions when building an MlsGroup(Config).
  • #1475: Fully process GroupContextExtension proposals
  • #1477: Allow setting leaf node extensions and capabilities of the group creator when creating an MlsGroup(Config)
  • #1478: Remove explicit functions to set RequiredCapabilitiesExtension and ExternalSendersExtension when building an MlsGroup(Config) in favor of the more general function to set group context extensions
  • #1479: Allow the use of extensions with ExtensionType::Unknown in group context, key packages and leaf nodes
  • #1488: Allow unknown credentials. Credentials other than the basic credential or X.509 may be used now as long as they are encoded as variable-sized vectors.
  • #1527: CredentialType::Unknown is now called CredentialType::Other.
  • #1543: PreSharedKeyId.write_to_key_store() no longer requires the cipher suite.
  • #1546: Add experimental ciphersuite based on the PQ-secure XWing hybrid KEM (currently supported only by the libcrux crypto provider).
  • #1548: CryptoConfig is now replaced by just Ciphersuite.
  • #1542: Add support for custom proposals. ProposalType::Unknown is now called ProposalType::Other. Proposal::Unknown is now called Proposal::Other.
  • #1559: Remove the PartialEq type constraint on the error type of both the OpenMlsRand and OpenMlsKeyStore traits. Additionally, remove the Clone type constraint on the error type of the OpenMlsRand trait.
  • #1565: Removed OpenMlsKeyStore and replace it with a new StorageProvider trait in the openmls_traits crate.
  • #1606: Added additional LeafNodeParameters argument to MlsGroup.self_update() and MlsGroup.propose_self_update() to allow for updating the leaf node with custom parameters. MlsGroup::join_by_external_commit() now also takes optional parameters to set the capabilities and the extensions of the LeafNode.
  • #1615: Changes the AAD handling. The AAD is no longer persisted and needs to be set before every API call that generates an MlsMessageOut. The functions ProccessedMessage to accees the AAD has been renamed to aad().

Fixed

  • #1503: Fix CoreGroup to check for LastResortExtension before deleting leaf encryption keypair from the key store in new_from_welcome; this allows the same KeyPackage (with last resort extension) to be used to join multiple groups

0.5.0 (2023-07-20)

This release has many breaking API changes, a few of them are listed below:

  • #902: Implement External Add proposal (NewMember sender only) and replace Sender::NewMember by Sender::NewMemberProposal and Sender::NewMemberCommit for external proposals and external commits repectively
  • #903: Rename MlsGroup's resumptionn_secret to resumption_secret
  • #1058: Rename resumption_secret to resumption_psk
  • #900: Expose SerializedMlsGroup until issue #245 is done

  • #1123: Rename ResumptionPsk to ResumptionPskSecret and resumption_psk to resumption_psk_secret
  • #1155: MlsGroup.members() now returns an iterator over group members, MlsGroup.merge_staged_commit() no longer returns a Result
  • #1193: MlsGroup.propose_self_update takes the new LeafNode now instead of a KeyPackage. LeafNode.generate can be used to generate a new LeafNode for an update proposal.

  • #873: Signature sub-module of the ciphersuite module is now public.
  • #873: Signature keys can be imported and exported with the crypto-subtle feature.
