Support for Arduino API Core
This release adds support for Arduino API core. It means that as Arduino switch over to this new core our libraries should continue to work. It also fixes the immediate issue with MKR compilation.
There is one user level change in this release, and that is to ensure that when using the BasicArduinoInterruptAbstraction that you include the required header  BasicArduinoInterruptAbstraction.h . This is to allow for Arduino boards that are not fully supported so that in this case, any problems with the attachInterrupt method don't stop compilation.
