Going forward, MSRV increases will be major version increases. Fixes [#48]. + +## [1.8.1] - 2021-10-21 - **Yanked** <a name="1.8.1"></a> +### ***Yanked*** +*Not recommended due to introducing compilation error in Rust versions that worked with 1.8.0.* +### Changed +- Now uses cargo resolver version 2 to prevent dev-dependencies from enabling `std` feature on + optional dependencies. + +### Fixed +- Fixed compile failure when `std` feature is not enabled and `num-traits` is enabled under new + resolver. Now properly uses `libm` num-traits feature. + +## [1.8.0] - 2021-10-13 <a name="1.8.0"></a> +### Changed +- Now always implements `Add`, `Div`, `Mul`, `Neg`, `Rem`, and `Sub` traits. + Previously, these were only implemented under the `num-traits` feature. Keep in mind they still + convert to `f32` and back in the implementation. +- Minimum supported Rust version is now 1.51. +- Made crate package [REUSE compliant](https://reuse.software/). +- Docs now use intra-doc links instead of manual (and hard to maintain) links. +- The following methods on both `f16` and `bf16` are now `const`: + - `to_le_bytes` + - `to_be_bytes` + - `to_ne_bytes` + - `from_le_bytes` + - `from_be_bytes` + - `from_ne_bytes` + - `is_normal` + - `classify` + - `signum` + +### Added +- Added optional implementations of `zerocopy` traits `AsBytes` and `FromBytes` + under `zerocopy` cargo feature. By [@samcrow]. +- Implemented the `core::iter::Product` and `core::iter::Sum` traits, with the same caveat as above + about converting to `f32` and back under the hood. +- Added new associated const `NEG_ONE` to both `f16` and `bf16`. +- Added the following new methods on both `f16` and `bf16`: + - `copysign` + - `max` + - `min` + - `clamp` + +### Fixed +- Fixed a number of minor lints discovered due to improved CI. + +## [1.7.1] - 2021-01-17 <a name="1.7.1"></a> +### Fixed +- Docs.rs now generates docs for `bytemuck` and `num-traits` optional features. + +## [1.7.0] - 2021-01-17 <a name="1.7.0"></a> +### Added +- Added optional implementations of `bytemuck` traits `Zeroable` and `Pod` under `bytemuck` cargo + feature. By [@charles-r-earp]. +- Added optional implementations of `num-traits` traits `ToPrimitive` and `FromPrimitive` under + `num-traits` cargo feature. By [@charles-r-earp]. +- Added implementations of `Binary`, `Octal`, `LowerHex`, and `UpperHex` string format traits to + format raw `f16`/`bf16` bytes to string. + +### Changed +- `Debug` trait implementation now formats `f16`/`bf16` as float instead of raw bytes hex. Use newly + implemented formatting traits to format in hex instead of `Debug`. Fixes [#37]. + + +## [1.6.0] - 2020-05-09 <a name="1.6.0"></a> +### Added +- Added `LOG2_10` and `LOG10_2` constants to both `f16` and `bf16`, which were added to `f32` and + `f64` in the standard library in 1.43.0. By [@tspiteri]. +- Added `to_le/be/ne_bytes` and `from_le/be/ne_bytes` to both `f16` and `bf16`, which were added to + the standard library in 1.40.0. By [@bzm3r]. + +## [1.5.0] - 2020-03-03 <a name="1.5.0"></a> +### Added +- Added the `alloc` feature to support the `alloc` crate in `no_std` environments. By [@zserik]. The + `vec` module is now available with either `alloc` or `std` feature. + +## [1.4.1] - 2020-02-10 <a name="1.4.1"></a> +### Fixed +- Added `#[repr(transparent)]` to `f16`/`bf16` to remove undefined behavior. By [@jfrimmel]. + +## [1.4.0] - 2019-10-13 <a name="1.4.0"></a> +### Added +- Added a `bf16` type implementing the alternative + [`bfloat16`](https://en.wikipedia.org/wiki/Bfloat16_floating-point_format) 16-bit floating point + format. By [@tspiteri]. +- `f16::from_bits`, `f16::to_bits`, `f16::is_nan`, `f16::is_infinite`, `f16::is_finite`, + `f16::is_sign_positive`, and `f16::is_sign_negative` are now `const` fns. +- `slice::HalfBitsSliceExt` and `slice::HalfBitsSliceExt` extension traits have been added for + performing efficient reinterpret casts and conversions of slices to and from `[f16]` and + `[bf16]`. These traits will use hardware SIMD conversion instructions when available and the + `use-intrinsics` cargo feature is enabled. +- `vec::HalfBitsVecExt` and `vec::HalfFloatVecExt` extension traits have been added for + performing efficient reinterpret casts to and from `Vec<f16>` and `Vec<bf16>`. These traits + are only available with the `std` cargo feature. +- `prelude` has been added, for easy importing of most common functionality. Currently the + prelude imports `f16`, `bf16`, and the new slice and vec extension traits. +- New associated constants on `f16` type to replace deprecated `consts` module. + +### Fixed +- Software conversion (when not using `use-intrinsics` feature) now matches hardware rounding + by rounding to nearest, ties to even. Fixes [#24], by [@tspiteri]. +- NaN value conversions now behave like `f32` to `f64` conversions, retaining sign. Fixes [#23], + by [@tspiteri]. + +### Changed +- Minimum rustc version bumped to 1.32. +- Runtime target host feature detection is now used if both `std` and `use-intrinsics` features are + enabled and the compile target host does not support required features. +- When `use-intrinsics` feature is enabled, will now always compile and run without error correctly + regardless of compile target options. + +### Deprecated +- `consts` module and all its constants have been deprecated; use the associated constants on `f16` + instead. +- `slice::from_bits` has been deprecated; use `slice::HalfBitsSliceExt::reinterpret_cast` instead. +- `slice::from_bits_mut` has been deprecated; use `slice::HalfBitsSliceExt::reinterpret_cast_mut` + instead. +- `slice::to_bits` has been deprecated; use `slice::HalfFloatSliceExt::reinterpret_cast` instead. +- `slice::to_bits_mut` has been deprecated; use `slice::HalfFloatSliceExt::reinterpret_cast_mut` + instead. +- `vec::from_bits` has been deprecated; use `vec::HalfBitsVecExt::reinterpret_into` instead. +- `vec::to_bits` has been deprecated; use `vec::HalfFloatVecExt::reinterpret_into` instead. + +## [1.3.1] - 2019-10-04 <a name="1.3.1"></a> +### Fixed +- Corrected values of constants `EPSILON`, `MAX_10_EXP`, `MAX_EXP`, `MIN_10_EXP`, and `MIN_EXP` + in `consts` module, as well as setting `consts::NAN` to match value of `f32::NAN` converted to + `f16`. By [@tspiteri]. + +## [1.3.0] - 2018-10-02 <a name="1.3.0"></a> +### Added +- `slice::from_bits_mut` and `slice::to_bits_mut` for conversion between mutable `u16` and `f16` + slices. Fixes [#16], by [@johannesvollmer]. + +## [1.2.0] - 2018-09-03 <a name="1.2.0"></a> +### Added +- `slice` and optional `vec` (only included with `std` feature) modules for conversions between + `u16` and `f16` buffers. Fixes [#14], by [@johannesvollmer]. +- `to_bits` added to replace `as_bits`. Fixes [#12], by [@tspiteri]. +### Fixed +- `serde` optional dependency no longer uses its default `std` feature. +### Deprecated +- `as_bits` has been deprecated; use `to_bits` instead. +- `serialize` cargo feature is deprecated; use `serde` instead. + +## [1.1.2] - 2018-07-12 <a name="1.1.2"></a> +### Fixed +- Fixed compilation error in 1.1.1 on rustc < 1.27, now compiles again on rustc >= 1.10. Fixes + [#11]. + +## [1.1.1] - 2018-06-24 - **Yanked** <a name="1.1.1"></a> +### ***Yanked*** +*Not recommended due to introducing compilation error on rustc versions prior to 1.27.* +### Fixed +- Fix subnormal float conversions when `use-intrinsics` is not enabled. By [@Moongoodboy-K]. + +## [1.1.0] - 2018-03-17 <a name="1.1.0"></a> +### Added +- Made `to_f32` and `to_f64` public. Fixes [#7], by [@PSeitz]. + +## [1.0.2] - 2018-01-12 <a name="1.0.2"></a> +### Changed +- Update behavior of `is_sign_positive` and `is_sign_negative` to match the IEEE754 conforming + behavior of the standard library since Rust 1.20.0. Fixes [#3], by [@tspiteri]. +- Small optimization on `is_nan` and `is_infinite` from [@tspiteri]. +### Fixed +- Fix comparisons of +0 to -0 and comparisons involving negative numbers. Fixes [#2], by + [@tspiteri]. +- Fix loss of sign when converting `f16` and `f32` to `f16`, and case where `f64` NaN could be + converted to `f16` infinity instead of NaN. Fixes [#5], by [@tspiteri]. + +## [1.0.1] - 2017-08-30 <a name="1.0.1"></a> +### Added +- More README documentation. +- Badges and categories in crate metadata. +### Changed +- `serde` dependency updated to 1.0 stable. +- Writing changelog manually. + +## [1.0.0] - 2017-02-03 <a name="1.0.0"></a> +### Added +- Update to `serde` 0.9 and stable Rust 1.15 for `serialize` feature. + +## [0.1.1] - 2017-01-08 <a name="0.1.1"></a> +### Added +- Add `serde` support under new `serialize` feature. +### Changed +- Use `no_std` for crate by default. + +## 0.1.0 - 2016-03-17 <a name="0.1.0"></a> +### Added +- Initial release of `f16` type. + +[#2]: https://github.com/starkat99/half-rs/issues/2 +[#3]: https://github.com/starkat99/half-rs/issues/3 +[#5]: https://github.com/starkat99/half-rs/issues/5 +[#7]: https://github.com/starkat99/half-rs/issues/7 +[#11]: https://github.com/starkat99/half-rs/issues/11 +[#12]: https://github.com/starkat99/half-rs/issues/12 +[#14]: https://github.com/starkat99/half-rs/issues/14 +[#16]: https://github.com/starkat99/half-rs/issues/16 +[#23]: https://github.com/starkat99/half-rs/issues/23 +[#24]: https://github.com/starkat99/half-rs/issues/24 +[#37]: https://github.com/starkat99/half-rs/issues/37 +[#48]: https://github.com/starkat99/half-rs/issues/48 + +[@tspiteri]: https://github.com/tspiteri +[@PSeitz]: https://github.com/PSeitz +[@Moongoodboy-K]: https://github.com/Moongoodboy-K +[@johannesvollmer]: https://github.com/johannesvollmer +[@jfrimmel]: https://github.com/jfrimmel +[@zserik]: https://github.com/zserik +[@bzm3r]: https://github.com/bzm3r +[@charles-r-earp]: https://github.com/charles-r-earp +[@samcrow]: https://github.com/samcrow + + +[Unreleased]: https://github.com/starkat99/half-rs/compare/v1.8.2...HEAD +[1.8.2]: https://github.com/starkat99/half-rs/compare/v1.8.1...v1.8.2 +[1.8.1]: https://github.com/starkat99/half-rs/compare/v1.8.0...v1.8.1 +[1.8.0]: https://github.com/starkat99/half-rs/compare/v1.7.1...v1.8.0 +[1.7.1]: https://github.com/starkat99/half-rs/compare/v1.7.0...v1.7.1 +[1.7.0]: https://github.com/starkat99/half-rs/compare/v1.6.0...v1.7.0 +[1.6.0]: https://github.com/starkat99/half-rs/compare/v1.5.0...v1.6.0 +[1.5.0]: https://github.com/starkat99/half-rs/compare/v1.4.1...v1.5.0 +[1.4.1]: https://github.com/starkat99/half-rs/compare/v1.4.0...v1.4.1 +[1.4.0]: https://github.com/starkat99/half-rs/compare/v1.3.1...v1.4.0 +[1.3.1]: https://github.com/starkat99/half-rs/compare/v1.3.0...v1.3.1 +[1.3.0]: https://github.com/starkat99/half-rs/compare/v1.2.0...v1.3.0 +[1.2.0]: https://github.com/starkat99/half-rs/compare/v1.1.2...v1.2.0 +[1.1.2]: https://github.com/starkat99/half-rs/compare/v1.1.1...v1.1.2 +[1.1.1]: https://github.com/starkat99/half-rs/compare/v1.1.0...v1.1.1 +[1.1.0]: https://github.com/starkat99/half-rs/compare/v1.0.2...v1.1.0 +[1.0.2]: https://github.com/starkat99/half-rs/compare/v1.0.1...v1.0.2 +[1.0.1]: https://github.com/starkat99/half-rs/compare/v1.0.0...v1.0.1 +[1.0.0]: https://github.com/starkat99/half-rs/compare/v0.1.1...v1.0.0 +[0.1.1]: https://github.com/starkat99/half-rs/compare/v0.1.0...v0.1.1 |
