+## [Unreleased]
+
+## [1.8.2] - 2021-10-22 <a name="1.8.2"></a>
+### Fixed
+- Remove cargo resolver=2 from manifest to resolve errors in older versions of Rust that still
+  worked with 1.8.0. 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>

+- More README documentation.
+- Badges and categories in crate metadata.
