# Version 0.1.1 (March 04, 2024)

* Updated crate's metadata inside `Cargo.toml` file.

# Version 0.1.2 (March 04, 2024)

* Deprecated trait function `MatrixExt::is_one_dimension` in favor of a more concise name that is `MatrixExt::is_vector`.
* Updated `README` file: added library description and the `IdentityMatrix` example.

# Version 0.1.3 (March 05, 2024)

* Made a more prettier output produced by functions `print_rows_debug`, `print_columns_debug` and `print_diagonals_debug`.

* Corrected variable name in `print_diagonals_debug`: ~`cols`~ => `diags`

* Updated example in `README.md` and added output.

* Updated `Cargo.toml` file


# Version 0.2.0 (March 06, 2024)

* Added structs: `IntoRows`, `IntoCols` and `IntoDiags`, and their associated functions: `into_rows`, `into_cols`, `into_diags`.

* Added method `into_iter`.

* Added unchecked (unsafe) version of `row`, `col`, `diag`, `row_mut`, `col_mut` and `diag_mut` methods.

* Put description on `Row`, `Column`, `Diag`, `RowMut`, `ColumnMut` and `DiagMut` (The 1 dimensional iterators).

* Changed manual implementation of `Copy` and `Clone` to derive macro on 1D iterators (hope that will never cause a crash).

* Updated `README` file: added properties display on example.


# Version 0.3.0 (March 14, 2024) 

## 🚨 **BREAKING CHANGES**

* Removed method `into_iter` and changed clause `Into<Vec<Self::Element>>` into `Sized + IntoIterator<Self::Element>` on methods `into_rows`, `into_cols` and `into_diags`.

* Added clause `<I as IntoIterator>::IntoIter: ExactSizeIterator` inside `from_iter` method from `MatrixExtFromIter` trait.

* Removed the `Copy` constraint on generic parameter `T` inside `TransformStrategy<[[T; N]; M]> for Transpose` implementation

* Added `no_std` support, making now use of `std` module optional.


# Version 0.4.0 (March 15, 2024) 

## 🚨 **BREAKING CHANGES**

* Removed method `duplicate` in `MatrixExtMut`'s provided methods.

* Added method `diag_len`.

* Added methods `first` and `first_mut`.

* Added methods `last` and `last_mut`.

* Fixed `num_diags` overflow error: It now returns 0 for an empty matrix.

* Added a `prelude` module.

* Fields of struct `Observer` are now public.

* `InPlace` trait now requires Matrix as `MatrixExtMut` instead of `MatrixExt`.

* Implementation of `DoubleEndedIterator` for iterators `Row(Mut)`, `Column(Mut)`, `Diag(Mut)` now follows the behavior from the rust standard library documentation.

* Added implementation of `TransformStrategy` and `InPlace` for immutable references implementing these traits.

* Merged structs `IntoRows`, `IntoCols`, and `IntoDiags` into `IntoAxes`. Each function returning the old struct now returns `IntoAxes`

* Changed `Self: Sized + IntoIterator<Self::Element>` clause to `Self: Sized + IntoIterator, <Self as IntoIterator>::Item: IntoIterator<Item = Self::Element>` 

* Added new `InPlace` strategy struct: `SortBy`.

* Effectively added "std" feature.


# Version 0.5.0 (March 19, 2024)

## 🚨 **BREAKING CHANGES**

* Removed conditional compilation based on whether the `std` library is available (did not work as expected).

* Iterator `Enumerator` no more implements `DoubleEndedIterator`.

* Added `serde derive` attribute on `SortBy` struct.

* Added `impls` feature to enable use of `[[T; M]; N]` 2D array as a matrix.

* Removed method `clone_into` on `Access<'a, MatrixMutExt, AccessStrategy>`.

* Changed method `clone_into2` to `clone_into` on `Access<'a, MatrixExt, AccessStrategy>`.
 
* Removed `edition="2021"` inside `Cargo.toml`. 


# Version 0.6.0 (April 7, 2024)

## 🚨 **BREAKING CHANGES**

* Deprecated method name `dimensions` in favor of `shape` (hope this make things more concise).

* Added methods `swap_cols` and `swap_rows` on `MatrixMutExt` trait.

* Field `strategy` from struct `AccessMut` is now public.

* Renamed `SubMatrix` to `Submatrix`.

* Changed `PartialEq<Iterator<MatrixA>> for Iterator<MatrixA>` to `PartialEq<Iterator<MatrixA>> for Iterator<MatrixB>` for each 1D Iterator (Row, Column, Diag, Iter, and their -Mut versions).

* Added `Reshape`,  a new `AccessStrategy`. Panics if dimensions provided does not fit the number of elements of the matrix.

* Updated `Submatrix`: An end-bound Range index is now brought back to the index bound (cols - 1 or rows - 1) if it has a greater or equal value. 

* `edition="2021"` is back inside `Cargo.toml` ... 



# Version 0.7.0 (May 18, 2024)

* Replaced core::mem::swap by core::ptr::swap as gently suggested by the clippy tool.

* Refactored code inside MatrixExt implementation of 2D array `[[T; N]; M]` (an alert from clippy too)

* Updated some comments

* Added method `product2` and `neighbours` to `MatrixExt` trait methods
