Version Compatibility

Each new version of the API maintains backward compatibility with all versions of the adTempus server beginning with 4.0. Some features of the API will not be available when connected to an older server. The [RequiredVersion] attribute on API elements indicates the required minimum server version for that feature. Elements that are not marked with this attribute are supported on server version 4 and later.

Attempting to use an unsupported feature produces a FeatureNotSupportedException. Use Scheduler.ServerVersion or Scheduler.ServerVersionIsAtLeast to check the version of the connected server.

The API generally cannot connect to a server running a newer major version of adTempus (a connection error will be returned). Connections to newer versions within the same major version generally are supported.
