- Migrate to the new `Bound` API introduced by PyO3 0.21. ([#410](https://github.com/PyO3/rust-numpy/pull/410)) ([#411](https://github.com/PyO3/rust-numpy/pull/411)) ([#412](https://github.com/PyO3/rust-numpy/pull/412)) ([#415](https://github.com/PyO3/rust-numpy/pull/415)) ([#416](https://github.com/PyO3/rust-numpy/pull/416)) ([#418](https://github.com/PyO3/rust-numpy/pull/418)) ([#419](https://github.com/PyO3/rust-numpy/pull/419)) ([#420](https://github.com/PyO3/rust-numpy/pull/420)) ([#421](https://github.com/PyO3/rust-numpy/pull/421)) ([#422](https://github.com/PyO3/rust-numpy/pull/422))
- Add a `prelude` module to simplify importing method traits required by the `Bound` API. ([#417](https://github.com/PyO3/rust-numpy/pull/417))
- Extend documentation to cover some more surprising behaviours. ([#405](https://github.com/PyO3/rust-numpy/pull/405)) ([#414](https://github.com/PyO3/rust-numpy/pull/414))
- v0.20.0
- Increase MSRV to 1.56 released in October 2021 and available in Debain 12, RHEL 9 and Alpine 3.17 following the same change for PyO3. ([#378](https://github.com/PyO3/rust-numpy/pull/378))
- Add support for ASCII (`PyFixedString<N>`) and Unicode (`PyFixedUnicode<N>`) string arrays, i.e. dtypes `SN` and `UN` where `N` is the number of characters. ([#378](https://github.com/PyO3/rust-numpy/pull/378))
- Add support for the `bfloat16` dtype by extending the optional integration with the `half` crate. Note that the `bfloat16` dtype is not part of NumPy itself so that usage requires third-party packages like Tensorflow. ([#381](https://github.com/PyO3/rust-numpy/pull/381))
- Add `PyArrayLike` type which extracts `PyReadonlyArray` if a NumPy array of the correct type is given and attempts a conversion using `numpy.asarray` otherwise. ([#383](https://github.com/PyO3/rust-numpy/pull/383))
- v0.19.0
- Add `PyUntypedArray` as an untyped base type for `PyArray` which can be used to inspect arguments before more targeted downcasts. This is accompanied by some methods like `dtype` and `shape` moving from `PyArray` to `PyUntypedArray`. They are still accessible though, as `PyArray` dereferences to `PyUntypedArray` via the `Deref` trait. ([#369](https://github.com/PyO3/rust-numpy/pull/369))
- Drop deprecated `PyArray::from_exact_iter` as it does not provide any benefits over `PyArray::from_iter`. ([#370](https://github.com/PyO3/rust-numpy/pull/370))
- v0.18.0
- Add conversions from and to datatypes provided by the [`nalgebra` crate](https://nalgebra.org/). ([#347](https://github.com/PyO3/rust-numpy/pull/347))
- Drop our wrapper for NumPy iterators which were deprecated in v0.16.0 as ndarray's iteration facilities are almost always preferable. ([#324](https://github.com/PyO3/rust-numpy/pull/324))
- Dynamic borrow checking now uses a capsule-based API and therefore works across multiple extensions using PyO3 and potentially other bindings or languages. ([#361](https://github.com/PyO3/rust-numpy/pull/361))
- v0.17.2
- Fix unsound aliasing into `Box<[T]>` when converting them into NumPy arrays. ([#351](https://github.com/PyO3/rust-numpy/pull/351))
- v0.17.1
- Fix use-after-free in `PyArray::resize`, `PyArray::reshape` and `PyArray::reshape_with_order`. ([#341](https://github.com/PyO3/rust-numpy/pull/341))
- Fix UB in `ToNpyDims::as_dims_ptr` with dimensions of dynamic size (-1). ([#344](https://github.com/PyO3/rust-numpy/pull/344))
- v0.17.0
- Add dynamic borrow checking to safely construct references into the interior of NumPy arrays. ([#274](https://github.com/PyO3/rust-numpy/pull/274))
- The deprecated iterator builders `NpySingleIterBuilder::{readonly,readwrite}` and `NpyMultiIterBuilder::add_{readonly,readwrite}` now take referencces to `PyReadonlyArray` and `PyReadwriteArray` instead of consuming them.
- The destructive `PyArray::resize` method is now unsafe if used without an instance of `PyReadwriteArray`. ([#302](https://github.com/PyO3/rust-numpy/pull/302))
- Add support for `datetime64` and `timedelta64` element types via the `datetime` module. ([#308](https://github.com/PyO3/rust-numpy/pull/308))
- Add support for IEEE 754-2008 16-bit floating point numbers via an optional dependency on the `half` crate. ([#314](https://github.com/PyO3/rust-numpy/pull/314))
- The `inner`, `dot` and `einsum` functions can also return a scalar instead of a zero-dimensional array to match NumPy's types ([#285](https://github.com/PyO3/rust-numpy/pull/285))
- The `PyArray::resize` function supports n-dimensional contiguous arrays. ([#312](https://github.com/PyO3/rust-numpy/pull/312))
- Deprecate `PyArray::from_exact_iter` after optimizing `PyArray::from_iter`. ([#292](https://github.com/PyO3/rust-numpy/pull/292))
- Remove `DimensionalityError` and `TypeError` from the public API as they never used directly. ([#315](https://github.com/PyO3/rust-numpy/pull/315))
- Remove the deprecated `PyArrayDescr::get_type` which was replaced by `PyArrayDescr::typeobj` in the last cycle. ([#308](https://github.com/PyO3/rust-numpy/pull/308))
- Fix returning invalid slices from `PyArray::{strides,shape}` for rank zero arrays. ([#303](https://github.com/PyO3/rust-numpy/pull/303))
- v0.16.2
- Fix build on platforms where `c_char` is `u8` like Linux/AArch64. ([#296](https://github.com/PyO3/rust-numpy/pull/296))
- v0.16.1
- Fix build when PyO3's `multiple-pymethods` feature is used. ([#288](https://github.com/PyO3/rust-numpy/pull/288))
- v0.16.0
- Bump PyO3 version to 0.16 ([#259](https://github.com/PyO3/rust-numpy/pull/259))
- Support object arrays ([#216](https://github.com/PyO3/rust-numpy/pull/216))
- Support borrowing arrays that are part of other Python objects via `PyArray::borrow_from_array` ([#230](https://github.com/PyO3/rust-numpy/pull/230))
- Fixed downcasting ignoring element type and dimensionality ([#265](https://github.com/PyO3/rust-numpy/pull/265))
- `PyArray::new` is now `unsafe`, as it produces uninitialized arrays ([#220](https://github.com/PyO3/rust-numpy/pull/220))
- `PyArray::iter`, `NpySingleIterBuilder::readwrite` and `NpyMultiIterBuilder::add_readwrite` are now `unsafe`, as they allow aliasing mutable references to be created ([#278/](https://github.com/PyO3/rust-numpy/pull/278))
- The `npyiter` module is deprecated as rust-ndarray's facilities for iteration are more flexible and performant ([#280](https://github.com/PyO3/rust-numpy/pull/280))
- `PyArray::from_exact_iter` does not unsoundly trust `ExactSizeIterator::len` any more ([#262](https://github.com/PyO3/rust-numpy/pull/262))
- `PyArray::as_cell_slice` was removed as it unsoundly interacts with `PyReadonlyArray` allowing safe code to violate aliasing rules ([#260](https://github.com/PyO3/rust-numpy/pull/260))
- `rayon` feature is now removed, and directly specifying the feature via `ndarray` dependency is recommended ([#250](https://github.com/PyO3/rust-numpy/pull/250))
- `Element` trait and `PyArrayDescr` changes ([#256](https://github.com/PyO3/rust-numpy/pull/256)):
- `Element` trait has been simplified to `get_dtype()` and `IS_COPY`
