June 2025 — affinidi/affinidi-ssi-dart: Focused on stabilization and data contract integrity. Delivered a critical bug fix to CredentialStatus toJson serialization for V1 and V2, ensuring accurate revocation status and deterministic output order by always including id and type before other fields. This improvement enhances interoperability with external systems and downstream processors. No new features were released this month; the primary achievement was the fix, which reduces integration errors and support risk. Commit: 7c489011c19fc0c52ad503ab3a4639a4c649f6a4.
