0.9.2 (2024-10-03)

Technical release with source distribution.

0.9.1 (2024-10-01)

Bug fix

Fixed a bug in the construction of nullable arrays using :func:`ndonnx.asarray` where the shape of the null field would not match the values field if the provided np.ma.MaskedArray's mask was scalar.
Fixed a bug in the implementation of :func:`ndonnx.ones_like` where the static shape was being used to construct the array of ones.

0.9.0 (2024-08-30)

New features

User defined data types can now define how arrays with that dtype are constructed by implementing the make_array function.
User defined data types can now define how they are indexed (via __getitem__) by implementing the getitem function.
:class:`ndonnx.NullableCore` is now public, encapsulating nullable variants of `CoreType`s exported by ndonnx.

Bug fixes

Various operations that depend on the array's shape have been updated to work correctly with lazy arrays.
:func:`ndonnx.cumulative_sum` now correctly applies the include_initial parameter and works around missing onnxruntime kernels for unsigned integral types.
:func:`ndonnx.additional.make_nullable` applies broadcasting to the provided null array (instead of reshape like it did previously). This allows writing make_nullable(x, False) to turn an array into nullable.
User-defined data types that implement :class:`ndonnx._core.UniformShapeOperations` may now implement :func:`ndonnx.where` without requiring both data types be promotable.

Breaking change

Iterating over dynamic dimensions of :class:`~ndonnx.Array` is no longer allowed since it commonly lead to infinite loops when used without an explicit break condition.

0.8.0 (2024-08-22)

Bug fixes

Fixes parsing numpy arrays of type object (consisting of strings) as utf8. Previously this worked correctly only for 1d arrays.

Breaking change

:meth:`ndonnx.Array.shape` now strictly returns a tuple[int | None, ...], with unknown dimensions denoted by None. This relies on ONNX shape inference for lazy arrays.

0.7.0 (2024-08-12)

New features

Expose the :func:`ndonnx.isdtype` function.
Custom data types can now override array functions:
The :class:`ndonnx._experimental.UniformShapeOperations` now provides implementations of shape operations that are generic across all data types where each constituent field has the same shape (that of the overall array).

Other changes

Fixed various deprecation warnings.
Invoking a function using arrays with data types that lack a corresponding implementation now raise a :class:`UnsupportedOperationError`.

Bug fixes

Numerical operations like :func:`sin` now raise :class:`UnsupportedOperationError` when invoked using invalid data types like ndx.utf8 rather than implicitly casting.
Fixes bug causing a promotion error when implementing numerical operations like :func:`add` that involve type promotion.
Fixes scalar promotion logic to more accurately reflect the Array API standard. Promotion requires at least one array to be present and scalars adopt the dtype of the arrays being promoted with it. ndx.utf8 and ndx.nutf8 cannot be promoted with any other dtypes.
Fixes failure when broadcasting nullable data type arrays together in :func:`broadcast_arrays`.

0.6.1 (2024-07-12)

Bug fixes

Division now complies more strictly with the Array API standard by returning a floating-point result regardless of input data types.

0.6.0 (2024-07-11)

Other changes

ndonnx.promote_nullable is now publicly exported.

0.5.0 (2024-07-01)

Other changes

ndonnx now exports type annotations.

Bug fixes

__array_namespace__ now accepts the optional api_version argument to specify the version of the Array API to use.

0.4.0 (2024-05-16)

Breaking changes

The constant propagated value is no longer accessed from the eager_value property but instead the to_numpy() method.
Non Array API functions have been moved to the ndonnx.additional namespace.
