## [0.22.0] - WIP ## [0.22.0]
In this release, we are using the new version 0.2 of simba. One major change of that version is that the
use of `libm` is now opt-in when building targetting `no-std` environment. If you are using floating-point
operations with nalgebra in a `no-std` environment, you will need to enable the new `libm` feature
of nalgebra for your code to compile again.
### Added ### Added
* The `libm` feature that enables `libm` when building for `no-std` environment.
* The `libm-force` feature that enables `libm` even when building for a not `no-std` environment.
* `Cholesky::new_unchecked` which build a Cholesky decomposition without checking that its input is * `Cholesky::new_unchecked` which build a Cholesky decomposition without checking that its input is
positive-definite. It can be use with SIMD types. positive-definite. It can be use with SIMD types.
