Aries Framework JavaScript

Aries Framework JavaScript release 0.4.0 was (as noted above) a major milestone. The smooth deployment of AFJ 0.4.0 into Aries Bifold was impressive, especially the seamless upgrade of Mobile Wallets from [Indy SDK ]to Aries Askar storage. The addition of OpenID4VCs exchange protocols expands the use cases for Aries Framework JavaScript. The maintainers of the Aries Framework JavaScript library are looking to coordinate efforts to support the EU’s EUDI/ARF efforts in at least Aries Framework JavaScript and, ideally, all Aries implementations.

Aries Cloud Agent Python

Aries Cloud Agent Python (ACA-Py) Release 0.9.0 was an important upgrade that changes the dependency on the now archived Hyperledger Ursa project to its updated, improved replacement, AnonCreds CL Signatures. ACA-Py users are strongly encouraged to use Aries Askar for all deployments, and to eliminate the use of the Indy SDK. An Indy SDK to Askar migration document has been added to the documentation site, and a deprecation warning added to the ACA-Py startup.

Aries Framework Go

There was a significant uptick in activity around Aries Framework Go this quarter. The focus has been on adding support for the proposed SD-JWT verifiable credential approach, as well as updates to the DIF Presentation Exchange implementation, and VC Data Integrity Specification handling.
