Measurement Plug-In SDK for Python v3.0.1

What's Changed

• Bump versions to 3.0.1 for patch release (#1251)
• Restore session_management module export to service package (#1250)
  • Version 3.0.0 removed internal submodules from the session_management subpackage. However, previously shipped example code references these submodules, so version 3.0.1 re-adds the submodules for compatibility purposes.

Measurement Plug-In SDK for Python v3.0.0

What's Changed

• Add support for Measurement Remote Execution by populating deployment_target (#1194)
• Remove hardcoded nims references from _dotenvpath (#1213)
• gRPC stubs have been extracted into separate packages (#1212 #1216 #1217 #1218)
  • ni_measurement_plugin_sdk_service._internal.stubs has moved to ni.protobuf.types, ni.measurementlink.discovery.v1.proto, ni.measurementlink.pinmap.v1.proto, ni.measurementlink.sessionmanagement.v1.proto, and other packages.
  • These were technically internal APIs, but some of them were used externally and will now redirect to the new location. The redirects will be deprecated and removed in future releases.
• gRPC extensions and client classes have been extracted into separate packages (#1220 #1222 #1228)
  • ni_measurement_plugin_sdk_service.discovery has moved to ni.measurementlink.discovery.v1.client.
  • ni_measurement_plugin_sdk_service.pin_map has moved to ni.measurementlink.pinmap.v1.client.
  • ni_measurement_plugin_sdk_service.session_management has moved to ni.measurementlink.sessionmanagement.v1.client
  • These are public APIs, so the existing modules now redirect to the new location. The redirects will be deprecated and removed in future releases.
  • Previously deprecated functionality has been removed:
    • DiscoveryClient.register_measurement_service was replaced by register_service in version 1.2.0.
    • DiscoveryClient.registration_id and DiscoveryClient.stub were deprecated in version 1.2.0.
    • session_management.Reservation was replaced by MultiSessionReservation in version 1.1.0.
• Fix tests with resource names when InstrumentStudio 2025Q3 is installed (#1225)
• Enable PyPI "Trusted Publishing" (#1230)

Measurement Plug-In SDK for Python v2.1.0

Compatibility Notes

• The version for a measurement plug-in is now specified in the .serviceconfig file. If your plug-in specifies version using the constructor of the MeasurementService 'version' parameter and not with a 'version' element in the .serviceconfig file, the version will be ignored and your service will be registered as version 0.1.0.
• Configuration parameters with array types should be treated as Sequence[T] or Iterable[T] rather than List[T]. You can still index, iterate, slice, etc. but some operations such as concatenating with another list or tuple are not supported. If you need the parameter to be converted to a list or a tuple, you should do that in your measure() function. See this example.

New Measurement Plug-In Client Generator
