    • SecureSendingSeqNrService instances: one per MaS
    • Access policies according to AN193

Breaking changes

The following table lists the breaking changes, i.e. the ones that require re-compilation or even modification of the source code:

Topic Description
.NET Standard 2.0 The .NET Standard 2.0 format can only be referenced from .NET Framework v4.6.1 or higher; i.e. it could be required to change the target framework to a newer version.
KNX Secure For KNX Data Security and KNX IP Security, System.Security.Cryptography.ProtectedData needs to be referenced, i.e. by using the NuGet package manager. Avoid storing sensitive information decrypted. On Windows, the protected memory (DPAPI) is automatically used. For other systems: provide proprietary implementations and use RegisterProtectedDataProvider in order to register.
External assemblies

These are minimal versions for the external assemblies log4net and Autofac:

  • log4net 2.0.8
  • Autofac 4.6.2

It is recommended to reference them via NuGet, in order to get the correct dependencies for the corresponding target platform.
