## [0.29.1] - WIP
|
||||
|
||||
### Added
|
||||
|
||||
- The conversion trait `From<Vec<T>>` and method `from_vec_storage` for `RowDVector`. See [#975](https://github.com/dimforge/nalgebra/issues/975)
|
||||
|
||||
## [0.29.0]
|
||||
### Breaking changes
|
||||
- We updated to the version 0.6 of `simba`. This means that the trait bounds `T: na::RealField`, `na::ComplexField`,

### Modified
|
||||
* Use of traits like `alga::general::{RealField, ComplexField}` have now been replaced by
|
||||
`simba::scalar::{RealField, ComplexField}`.
|
||||
`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.
|
||||
* `From<&Matrix>` is now implemented for matrix slices.
|
||||
* `.try_set_magnitude(...)` which sets the magnitude of a vector, while keeping its direction.
|
||||
* Implementations of `From` and `Into` for the conversion between matrix slices and standard (`&[N]` `&mut [N]`) slices.
|
||||
|
||||
|
||||
### Modified
|
||||
* We started some major changes in order to allow non-Copy types to be used as scalar types inside of matrices/vectors.

||||

`UpperHex`, `Binary`, `Pointer`.

|
||||
