This issue groups minor (backwards compatible) extensions of the hierarchical platform metamodel - Enable direct connections between `OffChipNetworks` - Introduce `Sensor` and `Actuator` elements that can be connected to offchip networks - Enable modelling of the accessibility (e.g., private, public) of platform elements - Remove outdated platform architecture annotations - Add model migrators - While here, remove model migrators that have been active for at least 2 releases (keep generic ones) - Apply model migrators to all test & example models
