1.4.0-dev0

• Merged Pull Requests

  • Full changelog: 1.3.0...1.4.0

• Resolved Issues

  • 820: Create a synchronization example for TDMS logging
  • 862: docs tox env fails on rdss-nidaqmxbot-win-10-py32

• Major Changes

1.3.0

1.3.0

• Merged Pull Requests

  • Full changelog: 1.2.0...1.3.0

• Resolved Issues

  • 843: read methods use task.in_stream.channels_to_read, which is slow
  • 639: first_samp_timestamp_val property does not work because LibraryInterpreter is missing a method

• Major Changes

  • (IN PROGRESS behind "WAVEFORM_SUPPORT" feature toggle) Added support for reading and writing Waveform data.
  • Simplify numpy and click version constraints.
    • nidaqmx supports a wider range of Python versions than numpy and click, so testing
      nidaqmx against its oldest supported Python version (currently 3.9) requires downgrading
      to older versions of numpy and click.
    • Previously, these testing-specific version constraints leaked into to the nidaqmx
      distribution package and affected clients. Adding PyPy-specific markers exacerbated
      this problem by requiring clients to specify the same markers.
    • numpy 2.0.x is the last version that supports Python 3.9, and it crashes with Python
      3.13, so the nidaqmx distribution package specifies two numpy version constraints:
      one for Python 3.9-3.12 (numpy>=1.22) and one for Python 3.13+ (numpy>=2.1).
    • The nidaqmx distribution package now specifies only a lower bound for click.
  • Clarify PyPy support and enable unit testing with PyPy.
  • Adopt ni-python-styleguide for hand-written code.
  • Upgrade to Poetry 2.x and migrate pyproject.toml format.
  • Add support for Python 3.14.
  • Add https://github.com/ni/ni-apis as a submodule of nidaqmx-python.
  • Add an optional dependency on ni.grpcdevice.v1.proto.
    • The internal session_pb2 submodule has been moved to the shared package ni.grpcdevice.v1.proto. Installing the nidaqmx package's grpc extra will automatically install this package.
    • If you get ModuleNotFoundError: No module named 'session_pb2', make sure you are installing the nidaqmx package's grpc extra.
