## [0.28.0]
### Added
- Implement `Hash` for `Transform`.
- Implement `Borrow` and `BorrowMut` for contiguous slices.
### Modified
- The `OPoint<T, D>` type has been added. It takes the dimension number as a type-level integer (e.g. `Const<3>`) instead
of a const-generic. The type `Point<T, const D: usize>` is now an alias for `OPoint`. This changes doesn't affect any
of the existing code using `Point`. However, it will allow the use `OPoint` in a generic context where the dimension
cannot be easily expressed as a const-generic (because of the current limitation of const-generics in Rust).
- Several clippy warnings were fixed. This results in some method signature changes (e.g. taking `self` instead of `&self`)
but this should not have any practical infulances on existing codebase.
- The `Point::new` constructors are no longer const-fn. This is due to some limitations in const-fn
not allowing custom trait-bounds. Use the `point!` macro instead to build points in const environments.
- `Dynamic::new` and `Unit::new_unchecked` are now const-fn.
- Methods returning `Result<(), ()>` now return `bool` instead.
### Fixed
- Fixed a potential unsoundess issue when converting a mutable slice to a `&mut[T]`.
## [0.27.1]
### Fixed
- Fixed a bug in the conversion from `glam::Vec2` or `glam::DVec2` to `Isometry2`.
## [0.27.0]
This removes the `convert-glam` and `convert-glam-unchecked` optional features.
Instead, this adds the `convert-glam013`, `convert-glam014`, and `convert-glam015` optional features for
