## 0.3.1

## 0.2.3

* Removed `BATCH_SIZE` generic constant value from `CellularAutomatonPlugin`
* Added `SimulationBatch` resource to handle parallel computation and batches
* Auto coloring job optimized

* Removed `2d_wireworld` example. A better standalone version is available [here](https://github.com/ManevilleF/wireworld-rs)

## 0.2.2

* Added `CellMap<T>::get_cell` method to retrieve a cell entity
* Added a `SimulationPause` resource to allow simulation pausing
* Improved logging in systems
* `CellMap<T>::insert_cell` now returns the previus entity if it was present

## 0.2.1

* `CellMap`:
  * Using a `bevy::utils::Hashmap` instead of the standard library one, which
  is slightly faster
* Cells system:
  * Removed reference counting `Arc` from the `RwLock` for the batched query iterations
* Using batched queries for the coloring systems (`auto-coloring` feature)
* Examples:
  * Improved examples map sizes
  * Reworked the color system for the provided `CellStates`
* Issues Github template

## 0.2.0

### Changed (**BREAKING CHANGES**)

* `3D` feature gate is no longer enabled by default
* Complete rework of the `auto-coloring` features, these changes are not detailed
as this feature is provided for example purposes.

Renamed:

* `Cell2d` -> `MooreCell2d`
* `Cell3d` -> `MooreCell3d`
* `ClassicCellState` -> `ConwayCellState`

### Added

* New `Cell` implementations:
  * `NeumannCell2d` (4 neighbors)
  * `NeumannCell3d` (6 neighbors)
  * `HexagonCell2d` (6 neighbors in cubic space)
* New `CellState` implementations:
  * `Conway4555CellState` for game of life *4555* rules
  * `ImmigrationCellState` for the immigration game (bi color)
  * `RainbowCellState` for the rainbow game (gray scale)

The `CellularAutomatonPlugin` now takes an additional `BATCH_SIZE: usize` const
parameter defining the new query batch size for better parallel execution.
The system handling cells and states now uses parallel querying with this new parameter

New examples are added.
