# Release 0.3.0 (2020-06-13)
### Enhancements
- [`Ratio` now implements `ToPrimitive`][52].
- [`Ratio` now implements additional formatting traits][56]:
- `Binary`, `Octal`, `LowerHex`, `UpperHex`, `LowerExp`, `UpperExp`
- [The `Pow` implementations have been expanded][70].
- `Pow<BigInt>` and `Pow<BigUint>` are now implemented.
- `Pow<_> for &Ratio<T>` now uses `&T: Pow`.
- The inherent `pow` method now uses `&T: Pow`.
### Breaking Changes
- [`num-rational` now requires Rust 1.31 or greater][66].
- The "i128" opt-in feature was removed, now always available.
- [The "num-bigint-std" feature replaces "bigint" with `std` enabled][80].
- The "num-bigint" feature without `std` uses `alloc` on Rust 1.36+.

# Release 0.2.3 (2020-01-09)
- [`Ratio` now performs earlier reductions to avoid overflow with `+-*/%` operators][42].
- [`Ratio::{new_raw, numer, denom}` are now `const fn` for Rust 1.31 and later][48].
- [Updated the `autocfg` build dependency to 1.0][63].

# Release 0.2.2 (2019-06-10)
- [`Ratio` now implements `Zero::set_zero` and `One::set_one`][47].

# Release 0.2.1 (2018-06-22)
- Maintenance release to fix `html_root_url`.
# Release 0.2.0 (2018-06-19)
### Enhancements
- [`Ratio` now implements `One::is_one` and the `Inv` trait][19].
- [`Ratio` now implements `Sum` and `Product`][25].
- [`Ratio` now supports `i128` and `u128` components][29] with Rust 1.26+.
- [`Ratio` now implements the `Pow` trait][21].
### Breaking Changes
- [`num-rational` now requires rustc 1.15 or greater][18].
- [There is now a `std` feature][23], enabled by default, along with the
implication that building *without* this feature makes this a `#![no_std]`
crate. A few methods now require `FloatCore` instead of `Float`.
- [The `serde` dependency has been updated to 1.0][24], and `rustc-serialize`
is no longer supported by `num-rational`.
- The optional `num-bigint` dependency has been updated to 0.2, and should be
enabled using the `bigint-std` feature. In the future, it may be possible
to use the `bigint` feature with `no_std`.

# Release 0.1.42 (2018-02-08)
- Maintenance release to update dependencies.
# Release 0.1.41 (2018-01-26)
- [num-rational now has its own source repository][num-356] at [rust-num/num-rational][home].
- [`Ratio` now implements `CheckedAdd`, `CheckedSub`, `CheckedMul`, and `CheckedDiv`][11].
- [`Ratio` now implements `AddAssign`, `SubAssign`, `MulAssign`, `DivAssign`, and `RemAssign`][12]
with either `Ratio` or an integer on the right side. The non-assignment operators now also
accept integers as an operand.
- [`Ratio` operators now make fewer `clone()` calls][14].
