This project adheres to [Semantic Versioning](https://semver.org/).
## [0.21.0]
In this release, we are no longer relying on traits from the __alga__ crate for our generic code.
Instead, we use traits from the new [simba](https://crates.io/crates/simba) crate which are both
simpler, and allow for significant optimizations like AoSoA SIMD.
Refer to the [monthly Rustsim blogpost](https://www.rustsim.org/blog/2020/04/01/this-month-in-rustsim/)
for details about this switch and its benefits.
### Added
* It is now possible to use SIMD types like `simba::f32x4` as scalar types for nalgebra's matrices and
geometric types.
### Modified
* Use of traits like `alga::general::{RealField, ComplexField}` have now been replaced by
`simba::scalar::{RealField, ComplexField}`.
* The implementation of traits from the __alga__ crate (and well as the dependency to _alga__) are now
omitted unless the `alga` cargo feature is activated.
### Removed
* The `Neg` unary operator is no longer implemented for `UnitComplex` and `UnitQuaternion`. This caused
hard-to-track errors when we mistakenly write, e.g., `-q * v` instead of `-(q * v)`.
* The `na::convert_unchecked` is no longer marked as unsafe.
## [0.20.0]
### Added
* `cholesky.rank_one_update(...)` which performs a rank-one update on the cholesky decomposition of a matrix.
