Big thank you to the release manager @​yf711, along with @​adrianlizarraga, @​HectorSVC, @​jywu-msft, and everyone else who helped to make this patch release process a smooth one!

ONNX Runtime v1.20.0

Release Manager: @​apsonawane

Announcements

  • All ONNX Runtime Training packages have been deprecated. ORT 1.19.2 was the last release for which onnxruntime-training (PyPI), onnxruntime-training-cpu (PyPI), Microsoft.ML.OnnxRuntime.Training (Nuget), onnxruntime-training-c (CocoaPods), onnxruntime-training-objc (CocoaPods), and onnxruntime-training-android (Maven Central) were published.
  • ONNX Runtime packages will stop supporting Python 3.8 and Python 3.9. This decision aligns with NumPy Python version support. To continue using ORT with Python 3.8 and Python 3.9, you can use ORT 1.19.2 and earlier.
  • ONNX Runtime 1.20 CUDA packages will include new dependencies that were not required in 1.19 packages. The following dependencies are new: libcudnn_adv.so.9, libcudnn_cnn.so.9, libcudnn_engines_precompiled.so.9, libcudnn_engines_runtime_compiled.so.9, libcudnn_graph.so.9, libcudnn_heuristic.so.9, libcudnn_ops.so.9, libnvrtc.so.12, and libz.so.1.

Build System & Packages

  • Python 3.13 support is included in PyPI packages.
  • ONNX 1.17 support will be delayed until a future release, but the ONNX version used by ONNX Runtime has been patched to include a shape inference change to the Einsum op.
  • DLLs in the Maven build are now digitally signed (fix for issue reported here).
  • (Experimental) vcpkg support added for the CPU EP. The DML EP does not yet support vcpkg, and other EPs have not been tested.

Core

  • MultiLoRA support.
  • Reduced memory utilization.
    • Fixed alignment that was causing mmap to fail for external weights.
    • Eliminated double allocations when deserializing external weights.
    • Added ability to serialize pre-packed weights so that they don’t cause an increase in memory utilization when the model is loaded.
  • Support bfloat16 and float8 data types in python I/O binding API.

Performance

  • INT4 quantized embedding support on CPU and CUDA EPs.
