Release Summary

‌DIGIT 2.0 is a baselined release that has got few functional changes, but more of non-functional standardisation changes.

  • Functional: Introducing advance payment feature and Advance collection integration with W/S.

  • Non-functional: Upgrading spring boot and tracer version of all the backend services to enhance the range of non-functional benefits like performance, metrics, and security. Also, all digit services/configs are baselined to follow the Semantic Versioning. These would enable the partner eco-system, system Integrators and state teams for easy on-going upgrades and integrations.
