Changelog

• Unreleased

• v0.16.0

  • Bump PyO3 version to 0.16 (#259)
  • Support object arrays (#216)
  • Support borrowing arrays that are part of other Python objects via PyArray::borrow_from_array (#230)
  • Fixed downcasting ignoring element type and dimensionality (#265)
  • PyArray::new is now unsafe, as it produces uninitialized arrays (#220)
  • PyArray::iter, NpySingleIterBuilder::readwrite and NpyMultiIterBuilder::add_readwrite are now unsafe, as they allow aliasing mutable references to be created (#278/)
  • The npyiter module is deprecated as rust-ndarray's facilities for iteration are more flexible and performant (#280)
  • PyArray::from_exact_iter does not unsoundly trust ExactSizeIterator::len any more (#262)
  • PyArray::as_cell_slice was removed as it unsoundly interacts with PyReadonlyArray allowing safe code to violate aliasing rules (#260)
  • rayon feature is now removed, and directly specifying the feature via ndarray dependency is recommended (#250)
  • Element trait and PyArrayDescr changes (#256):
    • Element trait has been simplified to get_dtype() and IS_COPY
    • New PyArrayDescr methods: of, into_dtype_ptr, is_equiv_to
    • Added numpy::dtype function
    • Element is now implemented for isize
    • c32 / c64 have been renamed with Complex32 / Complex64
    • ShapeError has been split into TypeError and DimensionalityError
    • i32, i64, u32, u64 are now guaranteed to map to np.u?int{32,64}.
    • Removed cfg_if dependency
    • Removed DataType enum
  • Added PyArrayDescr::new constructor (#266)
  • New PyArrayDescr methods (#266):
    • num, base, ndim, shape, byteorder, char, kind, itemsize, alignment, flags, has_object, is_aligned_struct, names, get_field, has_subarray, has_fields, is_native_byteorder
    • Renamed get_type to typeobj

• v0.15.1

  • Make arrays produced via IntoPyArray, i.e. those owning Rust data, writeable (#235)
  • Fix thread-safety in internal API globals (#222)

  • Remove resolver from Cargo.toml
  • Bump PyO3 to 0.15

• v0.14.1

  • Fix MSRV support

• v0.14
