## 2.1.5-wip

- Fixed `operator -()` of Quaternion (Contributed by tlserver)
- Fixed `Matrix3.rotationY` direction (Contributed by tlserver, moritzblume)
- Added an operator== to Quaternion so that two instances of quaternions can
  be evaluated for equality.
- Require Dart 3.1

## 2.1.4

- Refactor the locations of the `SimplexNoise` related part files.

## 2.1.3

- `operator ==` overrides no longer take nullable arguments. This is only
  visible for classes that implement the interfaces defined in this package
  which no longer need to also widen the argument type.
- Deprecate `SimplexNoise` (see https:github.com/google/vector_math.dart/issues/270
  for more information).

## 2.1.2

- Fix to `Quad.copy` ([#221](https://github.com/google/vector_math.dart/issues/221))
