There was a release for Infomodel Serializer with some performance improvements (v5.0.3). These changes could be integrated into messaging services, if no problems arise.
The Infomodel itself got also updated. It may be discussed, if the Infomodel is backwards compatible and could be integrated smoothly into messaging services and then into DSC (but needs good compatibility checks). The reason is that IAIS is working on integrating messaging services into Broker Core for MDS see https://github.com/Mobility-Data-Space/MDS-Broker-Core/tree/feature/ids_messaging_services They would like to use the latest updates of serializer and infomodel dependencies in messaging-services
