# DirectML 1.4.2

- Add PIX markers support to redist to enable profiling graph at operator level.

# DirectML 1.4.1

- Bug fixes related to metacomands:
  - Fix DML_OPERATOR_BATCH_NORMALIZATION crash when the operator is created with DimensionCount > 5.
  - Fix DML_OPERATOR_MAX_POOLING1/2 binding order for optional output indices tensor. This did not affect the output, but when running with GPU validation enabled, an error would happen "Supplied parameters size doesn't match enumerated size".

# DirectML 1.4.0

- First release of DirectML as a redistributable NuGet package, [Microsoft.AI.DirectML](https://www.nuget.org/packages/Microsoft.AI.DirectML).
- Introduces two new feature levels since DirectML 1.1.0: [DML_FEATURE_LEVEL_3_0](https://docs.microsoft.com/windows/win32/direct3d12/dml-feature-level-history#dml_feature_level_3_0) and [DML_FEATURE_LEVEL_2_1](https://docs.microsoft.com/windows/win32/direct3d12/dml-feature-level-history#dml_feature_level_2_1).
  - Adds 44 new operators.
  - The maximum number of tensor dimensions has been increased from 5 to 8.
  - Select operators support additional tensor data types.
- Substantial performance improvements for several operators.
- Bug fixes.

- Introduces a new feature level: [DML_FEATURE_LEVEL_2_0](https://docs.microsoft.com/windows/win32/direct3d12/dml-feature-level-history#dml_feature_level_2_0).
  - Adds 19 new operators.
  - When binding an input resource for dispatch of an IDMLOperatorInitializer, it is now legal to provide a resource with D3D12_HEAP_TYPE_CUSTOM (in addition to D3D12_HEAP_TYPE_DEFAULT), as long as appropriate heap properties are also set.
  - Select operators support 8-bit integer tensors.
  - 5D activation functions now support the use of strides on their input and output tensors.
- Substantial performance improvements for several operators.
- Bug fixes.
