# Change Log
All notable changes to `nalgebra`, starting with the version 0.6.0 will be
documented in this file (sorry I didn't maintain one before).
documented here.
This project adheres to [Semantic Versioning](http://semver.org/).
## [unreleased] [0.6.0]
## [0.6.0]
**Announcement:** a users forum has been created for `nalgebra`, `ncollide`, and `nphysics`. See
you [there](http://users.nphysics.org)!
### Added
* (feature=generic_sizes): Dependency to [generic-array](https://crates.io/crates/generic-array)
* (feature=ganedic_sizes): Staticly sized vectors with user-defined sizes: `VecN`.
* Dependency to [generic-array](https://crates.io/crates/generic-array). Feature-gated: requires
`features="generic_sizes"`.
* Staticly sized vectors with user-defined sizes: `VecN`. Feature-gated: requires
`features="generic_sizes"`.
* Similarity transformations (an uniform scale followed by a rotation followed
by a translation): `Sim2`, `Sim3`.
### Removed
* Zero-sized elements `Vec0`, `Pnt0`.
* Incomplete 4-dimensional transformations `Rot4` and `Iso4`.
* Removed zero-sized elements `Vec0`, `Pnt0`.
* Removed 4-dimensional transformations `Rot4` and `Iso4` (which had an implementation to incomplete to be useful).
### Modified
* Vectors are now multipliable à isometries. This will result into a pure rotation (this is how
vectors differ from point semantically: they design directions so they are not translatable).
* `{Iso3, Rot3}::look_at` reimplemented and renamed to `::look_at_rh` and `::look_at_lh` to agree
with the computer graphics community (in particuliar, the GLM library). Use the `::look_at_rh`
variant to build a view matrix that
may be successfully used with `Persp` and `Ortho`.
* The old `{Iso3, Rot3}::look_at` implementations are now called `::new_observer_frame`.
* Rename every `fov` on `Persp` to `fovy.
* Fixed the perspective and orthographic projection matrices.
