# Release 0.4.6 (2024-05-07)
- [Upgrade to 2021 edition, **MSRV 1.60**][121]
- [Add `const ZERO`/`ONE`/`I` and implement `ConstZero` and `ConstOne`][125]
- [Add `c32` and `c64` functions to help construct `Complex` values][126]

# Release 0.4.5 (2024-02-06)
- [Relaxed `T` bounds on `serde::Deserialize` for `Complex<T>`.][119]
**Contributors**: @cuviper, @WalterSmuts
[119]: https://github.com/rust-num/num-complex/pull/119
# Release 0.4.4 (2023-08-13)
- [Fixes NaN value for `powc` of zero][116]
**Contributors**: @cuviper, @domna
[116]: https://github.com/rust-num/num-complex/pull/116
# Release 0.4.3 (2023-01-19)
- [`Complex` now optionally supports `bytecheck` 0.6 and `rkyv` 0.7][110].
**Contributors**: @cuviper, @zyansheep
[110]: https://github.com/rust-num/num-complex/pull/110
# Release 0.4.2 (2022-06-17)
- [The new `ComplexFloat` trait][95] provides a generic abstraction between
floating-point `T` and `Complex<T>`.

# Release 0.4.1 (2022-04-29)
- [`Complex::from_str_radix` now returns an error for radix > 18][90], because
'i' and 'j' as digits are ambiguous with _i_ or _j_ imaginary parts.
- [`Complex<T>` now implements `bytemuck` traits when `T` does][100].
- [`Complex::cis` creates a complex with the given phase][101], _e_<sup>_i_ θ</sup>.

# Release 0.4.0 (2021-03-05)
- `rand` support has been updated to 0.8, requiring Rust 1.36.
**Contributors**: @cuviper
# Release 0.3.1 (2020-10-29)
- Clarify the license specification as "MIT OR Apache-2.0".
**Contributors**: @cuviper
# Release 0.3.0 (2020-06-13)
### Enhancements
- [The new "libm" feature passes through to `num-traits`][73], enabling `Float`
features on no-`std` builds.
### Breaking Changes
- `num-complex` now requires Rust 1.31 or greater.
- The "i128" opt-in feature was removed, now always available.
- [Updated public dependences][65]:
- `rand` support has been updated to 0.7, requiring Rust 1.32.
- [Methods for `T: Float` now take values instead of references][82], most
notably affecting the constructor `from_polar`.

# Release 0.2.4 (2020-01-09)
- [`Complex::new` is now a `const fn` for Rust 1.31 and later][63].
- [Updated the `autocfg` build dependency to 1.0][68].

# Release 0.2.3 (2019-06-11)
- [`Complex::sqrt()` is now more accurate for negative reals][60].
- [`Complex::cbrt()` computes the principal cube root][61].

# Release 0.2.2 (2019-06-10)
- [`Complex::l1_norm()` computes the Manhattan distance from the origin][43].
- [`Complex::fdiv()` and `finv()` use floating-point for inversion][41], which
may avoid overflows for some inputs, at the cost of trigonometric rounding.
- [`Complex` now implements `num_traits::MulAdd` and `MulAddAssign`][44].
- [`Complex` now implements `Zero::set_zero` and `One::set_one`][57].
- [`Complex` now implements `num_traits::Pow` and adds `powi` and `powu`][56].

# Release 0.2.1 (2018-10-08)
- [`Complex` now implements `ToPrimitive`, `FromPrimitive`, `AsPrimitive`, and `NumCast`][33].
**Contributors**: @cuviper, @termoshtt
[33]: https://github.com/rust-num/num-complex/pull/33
# Release 0.2.0 (2018-05-24)
### Enhancements
- [`Complex` now implements `num_traits::Inv` and `One::is_one`][17].
- [`Complex` now implements `Sum` and `Product`][11].
- [`Complex` now supports `i128` and `u128` components][27] with Rust 1.26+.
- [`Complex` now optionally supports `rand` 0.5][28], implementing the
`Standard` distribution and [a generic `ComplexDistribution`][30].
- [`Rem` with a scalar divisor now avoids `norm_sqr` overflow][25].
### Breaking Changes
- [`num-complex` now requires rustc 1.15 or greater][16].
- [There is now a `std` feature][22], enabled by default, along with the
implication that building *without* this feature makes this a `#![no_std]`
crate. A few methods now require `FloatCore`, and the remaining methods
based on `Float` are only supported with `std`.
- [The `serde` dependency has been updated to 1.0][7], and `rustc-serialize`
is no longer supported by `num-complex`.
