 This project adheres to [Semantic Versioning](https://semver.org/).
 
+## [0.31.0] (30 Apr. 2022)
+
+### Breaking changes
+- Switch to `cust` 0.3 (for CUDA support).
+- Switch to `rkyv` 0.7
+- Remove support for serialization based on `abomonation`.
+- Remove support for conversions between `nalgebra` types and `glam` 0.13.
+
+### Modified
+- The aliases for `Const` types have been simplified to help `rust-analyzer`.
+
+### Added
+- Add `TryFrom` conversion between `UnitVector2/3/4` and `glam`’s `Vec2/3/4`.
+- `nalgebra-sparse`: added support for serialization of sparse matrices with `serde`.
+- `nalgebra-sparse`: add a CSC matrix constructor from unsorted (but valid) data.
+- `nalgebra-lapack`: add generalized eigenvalues/eigenvectors calculation + QZ decomposition.
+
+### Fixed
+- Improve stability of SVD.
+- Fix slerp for `UnitComplex`.
+
 ## [0.30.1] (09 Jan. 2022)
+
 ### Added
 - Add conversion from/to types of `glam` 0.19 and 0.20.

 This project adheres to [Semantic Versioning](https://semver.org/).
 
+## [0.31.0] (30 Apr. 2022)
+
+### Breaking changes
+- Switch to `cust` 0.3 (for CUDA support).
+- Switch to `rkyv` 0.7
+- Remove support for serialization based on `abomonation`.
+- Remove support for conversions between `nalgebra` types and `glam` 0.13.
+
+### Modified
+- The aliases for `Const` types have been simplified to help `rust-analyzer`.
+
+### Added
+- Add `TryFrom` conversion between `UnitVector2/3/4` and `glam`’s `Vec2/3/4`.
+- `nalgebra-sparse`: added support for serialization of sparse matrices with `serde`.
+- `nalgebra-sparse`: add a CSC matrix constructor from unsorted (but valid) data.
+- `nalgebra-lapack`: add generalized eigenvalues/eigenvectors calculation + QZ decomposition.
+
+### Fixed
+- Improve stability of SVD.
+- Fix slerp for `UnitComplex`.
+
 ## [0.30.1] (09 Jan. 2022)
+
 ### Added
 - Add conversion from/to types of `glam` 0.19 and 0.20.

Subject: [PATCH 131/356] Implement `cast` for `Unit<Vector<T, D, S>>`

Currently, `cast` is resolved via `Unit`'s `Deref` impl, which leads
to it confusingly stripping the `Unit` from `UnitVector`s. Add an
inherent impl which takes precedence, similar to the existing
specialization for `UnitQuaternion`.

+## [0.31.1] (31 July 2022)
+
+### Modified
+- Improve performances of multiplication of two sparse matrices.
+
+### Added
+- Add `Matrix::from_row_iterator` to build a matrix from an iterator yielding components in row-major order.
+- Add support for conversion from/to types of `glam` 0.21.
+- `nalgebra-sparse`: add support for the matrix-market export of sparse matrices.
+- `nalgebra-lapack`: add a `GE` for solving the generalized eigenvalues problem.
+
+### Fixed
+- Fix `Rotation3::from_matrix` and `UnitQuaternion::from_matrix` when the input matrix is already a valid
+  rotation matrix.

Subject: [PATCH 207/356] Deprecate MatrixSliceMutMN

In the past, MatrixSliceMut did not have the same defaults. However,
for a while now MatrixSliceMut has served the exact same purpose
(in fact their definitions are identical), so we should
deprecate MatrixSliceMutMN.

Subject: [PATCH 208/356] Deprecate MatrixSliceMutN

There is no other type alias with this naming convention. I believe it
is a remnant from the past, when we had e.g. MatrixN type aliases. But
these no longer exist, therefore I believe this alias should also be
removed, instead of updated to "MatrixViewMutN".

+## [0.32.0] (14 Jan. 2023)
+
+### Modified
+- Renamed all `MatrixSlice` types to `MatrixView`. In general all occurrences of the world `Slice` or `slice` have been
+  replaced by `View` or `view`.
+- Deprecated all the types involving `Slice` in its name, in favor of the word `View`.
+- Make it so that most `nalgebra` objects archive as themselves (when using `rkyv` for serialization).
+- Renamed `Dynamic` to `Dyn` and make `Dyn` a tuple struct.
+
+### Added
+- Add `Cholesky::ln_determinant` to compute the natural logarithm of the determinant of a matrix decomposed 
+  with Cholesky. This can be more numerically stable than computing the determinant itself when very small and/or
+  large values are involved.
+- Added new methods `Matrix::as_view` and `Matrix::as_view_mut`, which are very useful when working with view-based APIs.
+- Added parallel column iterator using `rayon`: `Matrix::par_column_iter` and `Matrix::par_column_iter_mut`. The `rayon`
+  feature must be enabled to access these methods.
+- Implement `ReshapableStorage` for matrix slices (only for unit strides at the moment).
+- Add `U0, U1, …` constants alongside the `U0, U1, …` types. This lets us write `U4` instead of `U4::name()` or
+  `Const::<4>` when we need const dimensions.
+
+### Fixed
+- Fixed the implementation of `Rotation3::euler_angles` to return the angles in the documented order (roll, pitch, yaw).

 ## Unreleased
 
+### Modified
+- Statically sized matrices are now serialized as tuples to match how serde
+  serialized plain arrays.
+- Don’t require `Scalar` for matrix `PartialEq` and `Eq`.
+
+### Added
+- Allow trailing punctuation in macros `vector!`, `matrix!`, `point!`, etc.
+- Add the methods `Matrix1::as_scalar`, `::as_scalar_mut`, `::to_scalar`, `::into_scalar`.
+- Add `Rotation3::euler_angles_ordered`, a generalized euler angles calculation.
+- Add the `glam-0.24` feature to enable conversion from/to types from `glam` v0.24.
+- Add the `lerp` method to points.
+- Implement `Clone` for `MatrixIter`.
+
 ### Fixed
 - Fixed severe catastrophic cancellation issue in variance calculation.

    It is often useful to convert one algebraic type to another. There are two main approaches for converting
    between types in `nalgebra-glm`:
    * Using function with the form `type1_to_type2` in order to convert an instance of `type1` into an instance of `type2`.

    `let sim: Similarity3<_> = na::convert(isometry)` will convert an `Isometry3` into a `Similarity3`.

Subject: [PATCH 317/356] Use std::hint::black_box consistently.

This also removes the `#![feature(bench_black_box)]`. This was
stabilized in Rust 1.66 and anyone building benchmarks will be
on that or later (as they previously would have been on nightly).

This also allows building `cargo build --all-targets` on stable
Rust as it no longer dies when hitting the feature addition in
the benchmarks.

Subject: [PATCH 319/356] `split_at` is only used by Rayon code.

This fixes an unused code warning. Since the code is `pub(crate)`,
it was only available within the crate and only used by Rayon
code, so it is no functional change to not compile it except
when the right feature is enabled.

Also, fix a minor typo in some non-doc comments.

Subject: [PATCH 346/356] Fix glm::is_normalized epsilon

The existing comparison bound of $\epsilon^2$ is improperly scaled for
testing an epsilon of the squared vector magnitude. Let $\epsilon$ be
our specified epsilon and $\delta$ be the permissible delta of the
squared magnitude. Thus, for a nearly-normalized vector, we have

$$\begin{align}
\sqrt{1 + \delta} &=  1 + \epsilon        \\
          \delta  &= (1 + \epsilon)^2 - 1 \\
          \delta  &=  \epsilon^2 + 2\epsilon
\text{ .}\end{align}$$

Since we only care about small epsilon, we can assume
that $\epsilon^2$ is small and just use $\delta = 2\epsilon$. And in
fact, [this is the bound used by GLM][GLM#isNormalized] (MIT license)
... except they're using `length` and not `length2` for some reason.

[GLM#isNormalized]: https://github.com/g-truc/glm/blob/b06b775c1c80af51a1183c0e167f9de3b2351a79/glm/gtx/vector_query.inl#L102

If we stick an epsilon of `1.0e-6` into the current implementation,
this gives us a computed delta of `1.0e-12`: smaller than the `f32`
machine epsilon, and thus no different than direct float comparison
without epsilon. This also gives an effetive epsilon of `5.0e-13`;
*much* less than the intended `1.0e-6` of intended permitted slack!
By doing a bit more algebra, we can find the effective epsilon is
$\sqrt{\texttt{epsilon}^2 + 1} - 1$. This patch makes the effective
epsilon $\sqrt{2\times\texttt{epsilon} + 1} - 1$ which still isn't
*perfect*, but it's effectively linear in the domain we care about,
only really making a practical difference above an epsilon of 10%.

TL;DR: the existing `is_normalized` considers a vector normalized if
the squared magnitude is within `epsilon*epsilon` of `1`. This is wrong
and it should be testing if it's within `2*epsilon`. This PR fixes it.

For absence of doubt, a comparison epsilon of $\texttt{epsilon}^2$ is
correct when comparing squared magnitude against zero, such as when
testing if a displacement vector is nearly zero.

 (#1369)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix: Normalize the column once more

The column may not be normalized if the `factor` is on a scale of 1e-40.
Possibly, f32 just runs out of precision.

There is likely a better solution to the problem.

* chore: Add test that fails before fix

* chore: add comment providing details on the householder fix.

* chore: rename regression test

 ### Breaking semantic change
-  * The implementation of slicing with steps now matches the documentation.
-    Before, step identified the number to add to pass from one column/row index
-    to the next one. This made 0 step invalid. Now (and on the documentation so
-    far), the step is the number of ignored row/columns between each
-    row/column. Thus, a step of 0 means that no row/column is ignored.  For
-    example, a step of, say, 3 on previous versions should now bet set to 2.

 ## [0.11.0]
+
 The [website](https://nalgebra.org) has been fully rewritten and gives a good
 overview of all the added/modified features.
 
 This version is a major rewrite of the library. Major changes are:
-  * Algebraic traits are now defined by the [alga](https://crates.io/crates/alga) crate.
-    All other mathematical traits, except `Axpy` have been removed from
-    **nalgebra**.
-  * Methods are now preferred to free functions because they do not require any
-    trait to be used anymore.
-  * Most algebraic entities can be parametrized by type-level integers
-    to specify their dimensions. Using `Dynamic` instead of a type-level
-    integer indicates that the dimension known at run-time only.
-  * Statically-sized **rectangular** matrices.
-  * More transformation types have been added: unit-sized complex numbers (for
-    2D rotations), affine/projective/general transformations with `Affine2/3`,
-    `Projective2/3`, and `Transform2/3`.
-  * Serde serialization is now supported instead of `rustc_serialize`. Enable
-    it with the `serde-serialize` feature.
-  * Matrix **slices** are now implemented.

 Lots of features including rectangular matrices, slices, and Serde
 serialization. Refer to the brand new [website](https://nalgebra.org) for more
 details. The following free-functions have been added as well:

-    of type `Id`.
-  * `::inf_sup()` that returns both the infimum and supremum of a value at the
-    same time.
-  * `::partial_sort2()` that attempts to sort two values in increasing order.
-  * `::wrap()` that moves a value to the given interval by adding or removing
-    the interval width to it.
