This is a short blog post to give you a clear picture of the two versions of the Data Access Extension(DAE) SDKs we currently support in SAP Lumira. If you are starting to develop a new data access extension, we recommend you to use the Version 2 SDK. The following table will give you a better idea of the new features that we support with the V2 SDK,
