# Change Log

All notable changes to this project will be documented in this file, following
the format defined at [keepachangelog.com](http://keepachangelog.com/).
This project adheres to [Semantic Versioning](http://semver.org/).

## [Unreleased]

### Added
- Add missing by-ref and by-val permutations of `Quaternion` operators.
- Ease lifetime constraints by removing `'static` from some scalar type
  parameters.

### Removed
- Remove redundant `Point::{min, max}` methods - these are now covered by the
  `Array::{min, max}` methods that were introduced in 0.5.0.
- Removed `ToComponents`, `ToComponents2`, and `ToComponents3`. If you were
  relying on `ToComponents::decompose`, you can produce the same effect by
  accessing the fields on `Decomposed` directly. To create the scale vector,
  use: `Vector::from_value(transform.scale)`.
- Removed `CompositeTransform`, `CompositeTransform2`, and `CompositeTransform3`.

## [v0.6.0] - 2015-12-12

### Added
- This CHANGELOG for keeping track of notable changes.
- `Matrix4::{from_scale, from_nonuniform_scale}` for easily constructing
  homogeneous scale matrices.

### Changed
- Renamed `SquareMatrix::one` to `SquareMatrix::identity`. `identity` is easier
  to search for,
  and the more common name for the multiplicative identity for matrices.
- Matrix impls have now been constrained to `S: BaseFloat`.

## [v0.5.0] - 2015-11-20

### Changed
- Take many point and vector parameters by value.
- Take point and vector operator overloads by value.
- Divide `Matrix` trait into `Matrix` and `SquareMatrix`, opening the door for
  non-square matrices in the future.
- Make many trait type parameters associated types.
- Move element-wise methods from `Vector` and `Point` onto the `Array1` trait,
  and rename it to `Array`.
- Make pointer access methods on `Array` match the naming scheme of those in the
  standard library.

### Removed
- Removed collision types: `Ray`, `Plane`, `Frustum`, `Aabb2`, `Aabb3` `Obb2`,
  `Obb3` `Sphere`, `Cylinder`. These can now be found at
  [csherratt/collision-rs](https://github.com/csherratt/collision-rs).
- Remove `Array2` trait, moving methods onto the `Matrix` trait.
