Delegation evidence now supports conditions, which may reference attributes such as validFrom, validUntil, or certifications. Party-related endpoints have been redesigned with a new parties-and-claims structure to improve portability across data spaces. Verifiable Credentials support added, including standardised credential formats and presentation flows for identity and authorisation. Operational With introduction of Verifiable Credentials the roles and responsibilities are updated in the iSHARE Role model. Updated and clarified onboarding process for participants.
