# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog], and this project adheres to
[Semantic Versioning].
## [Unreleased]
## [0.8.7] - 2020-04-28
### Added
* Added `Quat::slerp` - note that this uses a `sin` approximation.
* Added `angle_between` method for `Vec2` and `Vec3`.
* Implemented `Debug`, `Display`, `PartialEq`, `Eq`, `PartialOrd`, `Ord`,
`Hash`, and `AsRef` traits for `Vec2Mask`, `Vec3Mask` and `Vec4Mask`.
* Added conversion functions from `Vec2Mask`, `Vec3Mask` and `Vec4Mask` to an
array of `[u32]`.
* Added `build.rs` to simplify conditional feature compilation.
### Changed
* Removed `cfg-if` dependency.
* Increased test coverage.
## [0.8.6] - 2020-02-18
### Added
* Added the `packed-vec3` feature flag to disable using SIMD types for `Vec3`
and `Mat3` types. This avoids wasting some space due to 16 byte alignment at
the cost of some performance.
* Added `x_mut`, `y_mut`, `z_mut`, `w_mut` where appropriate to `Vec2`, `Vec3`
and `Vec4`.
* Added implementation of `core::ops::Index` and `core::ops::IndexMut` for
`Vec2`, `Vec3` and `Vec4`.
### Changed
* Merged SSE2 and scalar `Vec3` and `Vec4` implementations into single files
using the `cfg-if` crate.
## [0.8.5] - 2020-01-02
### Added
* Added projection functions `Mat4::perspective_lh`,
`Mat4::perspective_infinite_lh`, `Mat4::perspective_infinite_reverse_lh`,
`Mat4::orthgraphic_lh` and `Mat4::orthographic_rh`.
* Added `round`, `ceil` and `floor` methods to `Vec2`, `Vec3` and `Vec4`.
## [0.8.4] - 2019-12-17
### Added
* Added `Mat4::to_scale_rotation_translation` for extracting scale, rotation and
translation from a 4x4 homogeneous transformation matrix.
* Added `cargo-deny` GitHub Action.
### Changed
* Renamed `Quat::new` to `Quat::from_xyzw`.
## [0.8.3] - 2019-11-27
### Added
* Added `Mat4::orthographic_rh_gl`.
### Changed
* Renamed `Mat4::perspective_glu_rh` to `Mat4::perspective_rh_gl`.
* SSE2 optimizations for `Mat2::determinant`, `Mat2::inverse`,
`Mat2::transpose`, `Mat3::transpose`, `Quat::conjugate`, `Quat::lerp`,
`Quat::mul_vec3`, `Quat::mul_quat` and `Quat::from_rotation_ypr`.
* Disabled optimizations to `Mat4::transform_point3` and
`Mat4::transform_vector3` as they are probably incorrect and need
investigating.
* Added missing `#[repr(C)]` to `Mat2`, `Mat3` and `Mat4`.
* Benchmarks now store output of functions to better estimate the cost of a
function call.
### Removed
* Removed deprecated functions `Mat2::new`, `Mat3::new` and `Mat4::new`.
## [0.8.2] - 2019-11-06
### Changed
* `glam_assert!` is no longer enabled by default in debug builds, it can be
enabled in any configuration using the `glam-assert` feature or in debug
builds only using the `debug-glam-assert` feature.
### Removed
* `glam_assert!`'s checking `lerp` is bounded between 0.0 and 1.0 and that
matrix scales are non-zero have been removed.
## [0.8.1] - 2019-11-03
### Added
* Added `Display` trait implementations for `Mat2`, `Mat3` and `Mat4`.
### Changed
* Disabled `glam`'s SSE2 `sin_cos` implementation - it became less precise for
large angle values.
* Reduced the default epsilon used by the `is_normalized!` macro from
`std::f32::EPSILON` to `1e-6`.
## [0.8.0] - 2019-10-14
### Removed
* Removed the `approx` crate dependency. Each `glam` type has an `abs_diff_eq`
method added which is used by unit tests for approximate floating point
comparisons.
* Removed the `Angle` type. All angles are now `f32` and are expected to
be in radians.
* Removed the deprecated `Vec2b`, `Vec3b` and `Vec4b` types and the `mask`
methods on `Vec2Mask`, `Vec3Mask` and `Vec4Mask`.
### Changed
* The `rand` crate dependency has been removed from default features. This was
required for benchmarking but a simple random number generator has been added
to the benches `support` module instead.
* The `From` trait implementation converting between 1D and 2D `f32` arrays and
matrix types have been removed. It was ambiguous how array data would map to
matrix columns so these have been replaced with explicit methods
`from_cols_array` and `from_cols_array_2d`.
* Matrix `new` methods have been renamed to `from_cols` to be consistent with
the other methods that create matrices from data.
* Renamed `Mat4::perspective_glu` to `Mat4::perspective_glu_rh`.
## [0.7.2] - 2019-09-22
### Fixed
* Fixed incorrect projection matrix methods `Mat4::look_at_lh`
and `Mat4::look_at_rh`.
### Added
* Added support for building infinite projection matrices, including both
standard and reverse depth `Mat4::perspective_infinite_rh` and
`Mat4::perspective_infinite_rh`.
* Added `Vec2Mask::new`, `Vec3Mask::new` and `Vec4Mask::new` methods.
* Implemented `std::ops` `BitAnd`, `BitAndAssign`, `BitOr`, `BitOrAssign`
and `Not` traits for `Vec2Mask`, `Vec3Mask` and `Vec4Mask`.
* Added method documentation for `Vec4` and `Vec4Mask` types.
* Added missing `serde` implementations for `Mat2`, `Mat3` and `Mat4`.
* Updated `rand` and `criterion` versions.
## [0.7.1] - 2019-07-08
### Fixed
* The SSE2 implementation of `Vec4` `dot` was missing a shuffle, meaning the
`dot`, `length`, `length_squared`, `length_reciprocal` and `normalize`
methods were sometimes incorrect.
### Added
* Added the `glam_assert` macro which behaves like Rust's `debug_assert` but
can be enabled separately to `debug_assert`. This is used to perform
asserts on correctness.
* Added `is_normalized` method to `Vec2`, `Vec3` and `Vec4`.
### Changed
* Replaced usage of `std::mem::uninitialized` with `std::mem::MaybeUninit`. This
change requires stable Rust 1.36.
* Renamed `Vec2b` to `Vec2Mask`, `Vec3b` to `Vec3Mask` and `Vec4b` to
`Vec4Mask`. Old names are aliased to the new name and deprecated.
* Deprecate `VecNMask` `mask` method, use new `bitmask` method instead
* Made fallback version of `VecNMask` types the same size and alignment as the
SIMD versions.
* Added `Default` support to `VecNMask` types, will add more common traits in
the future.
* Added `#[inline]` to `mat2`, `mat3` and `mat4` functions.
## [0.7.0] - 2019-06-28
### Added
* Added `Mat2` into `[f32; 4]`, `Mat3` into `[f32; 9]` and `Mat4` into
`[f32; 16]`.
### Changed
* Removed `impl Mul<&Vec2> for Mat2` and `impl Mul<&Vec3> for Vec3` as these
don't exist for any other types.
## [0.6.1] - 2019-06-22
### Changed
* `Mat2` now uses a `Vec4` internally which gives it some performance
improvements when SSE2 is available.
## 0.6.0 - 2019-06-13
### Changed
* Switched from row vectors to column vectors
* Vectors are now on the right of multiplications with matrices and quaternions.
