Version 1.0.0-alpha.37

Changes to JSON serialization format:

• Use of optional fields in snapshots where relevant (#12): collections which may be empty, null for optional parameters, and empty strings for applicationData.
• Optional text is nullable, rather than default empty string. This includes removing StudyInvitation.empty(), for which null is now preferred.
• Encoding of default values can now be disabled (and is disabled by default serializer) (cfdccc6).
• Duration is now serialized using ISO standard, rather than microseconds (#287).

Dependency updates:

• Kotlin 1.5.31
• coroutines 1.5.2

Common

• BatteryAwareSampling.low is no longer nullable (f57e39d).
• Bugfix: Make default sampling schemes in BatteryAwareSamplingScheme public (b603b9e).
• Renamed:
  • inputType to inputDataType in ParticipantAttribute and InputDataTypeList (fa78283).
  • InputElement.name to prompt (#262).
• MAC address builder can now use either : or - separators and accepts both lowercase and uppercase (8b28201).
• Removed DeviceRegistration.fromJson and toJson methods (6cf30f2). Use the default json.serialization encode/decode functions instead.
• Added DeviceDescriptor.getDefaultSamplingConfiguration() to facilitate client implementations (#311).
