Changelog

1.0.0-rc.1 (2023-09-29)

Full Changelog

This version introduces a new DID method targeting the IOTA UTXO ledger. This method works fundamentally differently from the previous method and introduces new capabilities to interact with Layer 1 assets like Native Tokens, NFTs and various Output types.

This version changes the credential and presentation format to JWT, as specified by the VC Data Model v1.1.

Note: Identities and credentials created with the earlier versions cannot be resolved with this version of the library.

v0.7.0-alpha.1 (2022-09-19)

Full Changelog

This version introduces a new DID method targeting the IOTA UTXO ledger. This method works fundamentally differently from the previous method and introduces new capabilities to interact with Layer 1 entities like native tokens, NFTs and smart contracts.

This is an early alpha release, so there may be breaking changes in upcoming versions that invalidate DIDs created with this version. The method at this point is only intended for experimentation.

Note: Identities created with the earlier versions cannot be resolved with this version of the library.

  • Support case insensitive serialization of RentStructure #1012
  • Update stronghold to 0.6.4 #928

v0.6.0 (2022-06-15)

Full Changelog

The main feature of this release is the addition of the RevocationBitmap2022 specification, offering efficient credential revocation on-Tangle. This is the replacement for the MerkleKeyCollection removed in v0.5.0, which offered similar functionality but fundamentally failed to scale beyond a few thousand revocations.

Other changes include encryption support using Elliptic Curve Diffie-Hellman (ECDH) and quality of life improvements for verifiable credential and presentation types in the Wasm bindings.

DID Documents created with v0.5.0 remain compatible with v0.6.0. This will be the last major release prior to changes for the Stardust update.

Changed

  • Rename crates to use underscores #895
  • Change remove_service to return boolean #877
  • Change DIDUrl::join to borrow self #871
  • Add BaseEncoding to replace encode_b58, decode_b58, encode_multibase, decode_multibase #870
  • Add RevocationBitmap2022, bump MSRV to 1.60 #861
  • Add Wasm Credential and Presentation field getters and constructors #815
  • Add Diffie-Hellman key exchange for encryption to Account #809

Added

  • Implement ECDH-ES+A256KW for Storage encryption #867
  • Add Client option for retry publishing behaviour #820
  • Implement Storage test suite #791

Patch

  • Unpin iota-crypto version #834

Removed

  • Remove unused resolution code #862

v0.5.0 (2022-03-31)

Full Changelog

This release introduces multiple breaking changes to the structure of IOTA DID Documents and their Tangle messages, rendering any identity created with a prior version incompatible and unresolvable. A versioning system has been introduced so any new identities should hopefully be forward compatible with any future breaking changes to the message structure.

The main feature of this release is the introduction of WebAssembly (Wasm) bindings for the high-level Account API for Javascript/Typescript in both Node.js and the browser. This includes preliminary Stronghold storage bindings but only for Node.js, as it was determined that compiling Stronghold to Wasm for the browser would not be sufficiently secure. Stronghold offers best-effort secure software storage for cryptographic keys, written in Rust. To use the Stronghold storage package install @iota/identity-stronghold-nodejs and follow the instructions of the package README.

Note that all features related to diff chain updates are now marked as deprecated. Diff chains are a useful optimisation when publishing many updates to a DID Document. However, their design may be incompatible with upcoming changes to the IOTA network and should be considered unstable.

Another major change is the removal of the MerkleKeyCollection verification method type, which provided a compact representation for issuing and revoking Verifiable Credentials with multiple cryptographic keys. The MerkleKeyCollection suffered from disadvantages which limited scalability when managing more than a few thousand keys. While these disadvantages could be mitigated somewhat, the decision was made to replace it with one or more alternatives not affected by its fundamental limitations, upcoming in the next major release.
