# Objective
- Partially addresses https://github.com/bevyengine/bevy/issues/11470
(I'd like to add Spatiotemporal Blue Noise in the future, but that's a
bit more controversial).
- Fix cluster_debug_visualization which has not compiled for a while
---
## Changelog
- Added random white noise shader functions to `bevy_pbr::utils`
## Migration Guide
- The `bevy_pbr::utils::random1D` shader function has been replaced by
the similar `bevy_pbr::utils::rand_f`.
# Objective
- During rendering of different gizmo groups, the ordering is random
between executions
## Solution
- Make the ordering stable
- It's using a `TypeIdMap`, its iteration order depends on the insertion
order. so insert when adding a group instead of when adding a gizmo
- Also changed `extract_gizmo_data` to not be group dependent. there
will be only one of those systems, no matter the number of gizmo groups
added

# Objective
`CameraProjectionPlugin<T>`'s bounds are `T: CameraProjection`. But the
bounds for `CameraProjectionPlugin` implementing `Plugin` are `T:
CameraProjection + Component + GetTypeRegistration`. This means that if
`T` is valid for `CameraProjectionPlugin`'s bounds, but not the plugin
implementation's bounds, then `CameraProjectionPlugin` would not
implement `Plugin`. Which is weird because you'd expect a struct with
`Plugin` in the name to implement `Plugin`.
## Solution
Make `CameraProjectionPlugin<T>`'s bounds `T: CameraProjection +
Component + GetTypeRegistration`. I also rearranged some of the code.
---
## Changelog
- Changed `CameraProjectionPlugin<T>`'s bounds to `T: CameraProjection +
Component + GetTypeRegistration`
## Migration Guide
`CameraProjectionPlugin<T>`'s trait bounds now require `T` to implement
`CameraProjection`, `Component`, and `GetTypeRegistration`. This
shouldn't affect most existing code as `CameraProjectionPlugin<T>` never
implemented `Plugin` unless those bounds were met.
# Objective
Split up from #12017, add an aligned version of `Direction3d` for SIMD,
and move direction types out of `primitives`.
## Solution
Add `Direction3dA` and move direction types into a new `direction`
module.
---
## Migration Guide
The `Direction2d`, `Direction3d`, and `InvalidDirectionError` types have
been moved out of `bevy::math::primitives`.
Before:
```rust
use bevy::math::primitives::Direction3d;
```
After:
```rust
use bevy::math::Direction3d;

# Objective
- Improve compatibility with CSS Module 4
- Simplify `Hsla` conversion functions
## Solution
- Added `Hsva` which implements the HSV color model.
- Added `Hwba` which implements the HWB color model.
- Updated `Color` and `LegacyColor` accordingly.
## Migration Guide
- Convert `Hsva` / `Hwba` to either `Hsla` or `Srgba` using the provided
`From` implementations and then handle accordingly.
## Notes
While the HSL color space is older than HWB, the formulation for HWB is
more directly related to RGB. Likewise, HSV is more closely related to
HWB than HSL. This makes the conversion of HSL to/from RGB more
naturally represented as the compound operation HSL <-> HSV <-> HWB <->
RGB. All `From` implementations for HSL, HSV, and HWB have been designed
to take the shortest path between itself and the target space.

# Objective
- We should move towards a consistent use of the new `bevy_color` crate.
- As discussed in #12089, splitting this work up into small pieces makes
it easier to review.
## Solution
- Port all uses of `LegacyColor` in the `bevy_core_pipeline` to
`LinearRgba`
- `LinearRgba` is the correct type to use for internal rendering types
- Added `LinearRgba::BLACK` and `WHITE` (used during migration)
- Add `LinearRgba::grey` to more easily construct balanced grey colors
(used during migration)
- Add a conversion from `LinearRgba` to `wgpu::Color`. The converse was
not done at this time, as this is typically a user error.
I did not change the field type of the clear color on the cameras: as
this is user-facing, this should be done in concert with the other
configurable fields.
## Migration Guide
`ColorAttachment` now stores a `LinearRgba` color, rather than a Bevy
0.13 `Color`.
`set_blend_constant` now takes a `LinearRgba` argument, rather than a
Bevy 0.13 `Color`.

# Objective
Right now when using egui, systems are inserted without any identifier
and to the root. I'd like to name those systems and insert them as
children to a root entity. This helps to keep the editor organized.
## Solution
- Although the `SystemId` is documented as an opaque type, examples
depicted above benefit from tear down of the abstraction.

# Objective
- followup to https://github.com/bevyengine/bevy/pull/11671
- I forgot to change the alpha masked phases.
## Solution
- Change the sorting for alpha mask phases to sort by pipeline+mesh
instead of distance, for much better batching for alpha masked
materials.
I also fixed some docs that I missed in the previous PR.
---
## Changelog
- Alpha masked materials are now sorted by pipeline and mesh.

# Objective
The multi-threaded executor currently runs in a dedicated task on a
single thread. When a system finishes running, it needs to notify that
task and wait for the thread to be available and running before the
executor can process the completion.
See #8304
## Solution
Run the multi-threaded executor at the end of each system task. This
allows it to run immediately instead of needing to wait for the main
thread to wake up. Move the mutable executor state into a separate
struct and wrap it in a mutex so it can be shared among the worker
threads.
While this should be faster in theory, I don't actually know how to
measure the performance impact myself.

# Objective
Partially address #888. Gilrs is initialized on a separate thread, and
thus conditionally implements `Send`, and all platforms other than Wasm.
This means the `NonSend` resource constraint is likely too conservative.
## Solution
Relax the requirement, and conditionally derive Resource on a wrapper
around it, using `SyncCell` to satisfy the `Sync` requirement on it.
# Objective
- Fixes#12081
## Solution
Passing the `Affine2` as a neatly packed `mat3x2` breaks WebGL with
`drawElementsInstanced: Buffer for uniform block is smaller than
UNIFORM_BLOCK_DATA_SIZE.`
I fixed this by using a `mat3x3` instead.
Alternative solutions that come to mind:
- Pass in a `mat3x2` on non-webgl targets and a `mat3x3` otherwise. I
guess I could use `#ifdef SIXTEEN_BYTE_ALIGNMENT` for this, but it
doesn't seem quite right? This would be more efficient, but decrease
code quality.
- Do something about `UNIFORM_BLOCK_DATA_SIZE`. I don't know how, so I'd
need some guidance here.
@superdump let me know if you'd like me to implement other variants.
Otherwise, I vote for merging this as a quick fix for `main` and then
improving the packing in subsequent PRs :)
## Additional notes
Ideally we should merge this before @JMS55 rebases #10164 so that they
don't have to rebase everything a second time.
# Objective
- Fixes#12068
## Solution
- Split `bevy_render::color::colorspace` across the various space
implementations in `bevy_color` as appropriate.
- Moved `From` implementations involving
`bevy_render::color::LegacyColor` into `bevy_render::color`

# Objective
- The bloom effect is currently somewhat costly (in terms of GPU time
used), due to using fragment shaders for down- and upscaling (compute
shaders generally perform better for such tasks).
- Additionally, one might have a `BloomSettings` on a camera whose
`intensity` is only occasionally set to a non-zero value (eg. in outside
areas or areas with bright lighting). Currently, the cost of the bloom
shader is always incurred as long as the `BloomSettings` exists.
## Solution
- Bail out of the bloom render node when `intensity == 0.0`, making the
effect free as long as it is turned all the way down.
# Objective
- Fixes#751
## Solution
- Added `PluginGroupBuilder::add_group`, which accepts an owned `impl
PluginGroup` and adds those plugins to self, following
`PluginGroupBuilder::add`'s replacement rules.
- Split `PluginGroupBuilder::upsert_plugin_state` into two functions,
one of the same name, and
`PluginGroupBuilder::upsert_plugin_entry_state` which takes a
`PluginEntry` and `TypeId` directly. This allows for shared behaviour
between `add` and `add_group`.
- Added 2 unit tests documenting the replacement behaviour in
`PluginGroupBuilder::add_group`.

# Objective
- The 3D Lighting example is meant to show using multiple lights in the
same scene.
- It currently looks very dark. (See [this
image](4fdb1455d5 (r1494653511)).)
- Resetting the physical camera properties sets the shutter speed to 1 /
125, even though it initially starts at 1 / 100.
## Solution
- Increase the intensity of all 3 lights in the example.
- Now it is much closer to the example in Bevy 0.12.
- I had to remove the comment explaining the lightbulb equivalent of the
intensities because I don't know how it was calculated. Does anyone know
what light emits 100,000 lumens?
- Set the initial shutter speed to 1 / 125.

# Objective
#7348 added `bevy_utils::Parallel` and replaced the usage of the
`ThreadLocal<Cell<Vec<...>>>` in `check_visibility`, but we were also
using it in `extract_meshes`.
## Solution
Refactor the system to use `Parallel` instead.
# Objective
The physical width and height (pixels) of an image is always integers,
but for `GpuImage` bevy currently stores them as `Vec2` (`f32`).
Switching to `UVec2` makes this more consistent with the [underlying
texture data](https://docs.rs/wgpu/latest/wgpu/struct.Extent3d.html).
I'm not sure if this is worth the change in the surface level API. If
not, feel free to close this PR.
## Solution
- Replace uses of `Vec2` with `UVec2` when referring to texture
dimensions.
- Use integer types for the texture atlas dimensions and sections.
[`Sprite::rect`](a81a2d1da3/crates/bevy_sprite/src/sprite.rs (L29))
remains unchanged, so manually specifying a sub-pixel region of an image
is still possible.
---
## Changelog
- `GpuImage` now stores its size as `UVec2` instead of `Vec2`.
- Texture atlases store their size and sections as `UVec2` and `URect`
respectively.
- `UiImageSize` stores its size as `UVec2`.
## Migration Guide
- Change floating point types (`Vec2`, `Rect`) to their respective
unsigned integer versions (`UVec2`, `URect`) when using `GpuImage`,
`TextureAtlasLayout`, `TextureAtlasBuilder`,
`DynamicAtlasTextureBuilder` or `FontAtlas`.
# Objective
- I hit an issue using the `file_watcher` feature to hot reload assets
for my game. The change in this PR allows me to now hot reload assets.
- The issue stemmed from my project being a multi crate workspace
project structured like so:
```
└── my_game
├── my_game_core
│ ├── src
│ └── assets
├── my_game_editor
│ └── src/main.rs
└── my_game
└── src/main.rs
```
- `my_game_core` is a crate that holds all my game logic and assets
- `my_game` is the crate that creates the binary for my game (depends on
the game logic and assets in `my_game_core`)
- `my_game_editor` is an editor tool for my game (it also depends on the
game logic and assets in `my_game_core`)
Whilst running `my_game` and `my_game_editor` from cargo during
development I would use `AssetPlugin` like so:
```rust
default_plugins.set(AssetPlugin {
watch_for_changes_override: Some(true),
file_path: "../my_game_core/assets".to_string(),
..Default::default()
})
```
This works fine; bevy picks up the assets. However on saving an asset I
would get the following panic from `file_watcher`. It wouldn't kill the
app, but I wouldn't see the asset hot reload:
```
thread 'notify-rs debouncer loop' panicked at /Users/ian/.cargo/registry/src/index.crates.io-6f17d22bba15001f/bevy_asset-0.12.1/src/io/file/file_watcher.rs:48:58:
called `Result::unwrap()` on an `Err` value: StripPrefixError(())
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```
## Solution
- The solution is to collapse dot segments in the root asset path
`FileWatcher` is using
- There was already bevy code to do this in `AssetPath`, so I extracted
that code so it could be reused in `FileWatcher`
# Objective

# Objective
- Sometimes, it is useful to get a `Handle<T>` from an `AssetId<T>`. For
example, when iterating `Assets` to find a specific asset. So much so
that it's possible to do so with `AssetServer::get_id_handle`
- However, `AssetServer::get_id_handle` doesn't work with assets
directly added to `Assets` using `Assets::add`.
- Fixes#12087
## Solution
- Add `Assets::get_strong_handle` to convert an `AssetId` into an
`Handle`
- Document `AssetServer::get_id_handle` to explain its limitation and
point to `get_strong_handle`.
- Add a test for `get_strong_handle`
- Add a `duplicate_handles` field to `Assets` to avoid dropping assets
with a live handle generated by `get_strong_handle` (more reference
counting yay…)
- Fix typos in `Assets` docs

## Changelog
- Add `Assets::get_strong_handle` to convert an `AssetId` into an
`Handle`

# Objective
The migration process for `bevy_color` (#12013) will be fairly involved:
there will be hundreds of affected files, and a large number of APIs.
## Solution
To allow us to proceed granularly, we're going to keep both
`bevy_color::Color` (new) and `bevy_render::Color` (old) around until
the migration is complete.
However, simply doing this directly is confusing! They're both called
`Color`, making it very hard to tell when a portion of the code has been
ported.
As discussed in #12056, by renaming the old `Color` type, we can make it
easier to gradually migrate over, one API at a time.
## Migration Guide

This change should not be shipped to end users: delete this section in
the final migration guide!

## Solution
* Run `System::apply_deferred` in `System::run` after executing the
system.
* Switch to using `System::run_unsafe` in `SingleThreadedExecutor` to
preserve the current behavior.
* Remove the `System::apply_deferred` in `SimpleExecutor` as it's now
redundant.
* Remove the `System::apply_deferred` when running one-shot systems, as
it's now redundant.

## Changelog
Changed: `System::run` will now immediately apply deferred system params
after running the system.
## Migration Guide
`System::run` will now always run `System::apply_deferred` immediately
after running the system now. If you were running systems and then
applying their deferred buffers at a later point in time, you can
eliminate the latter.

```
It would be nice if this could be backported to a 0.13.1 patch as well
if possible. I'm needing to rely on my own fork for now.
## Solution
Similar to the Globals uniform solution here:

# Objective
`Scope::spawn`, `Scope::spawn_on_external`, and `Scope::spawn_on_scope`
have different signatures depending on whether the `multi-threaded`
feature is enabled. The single-threaded version has a stricter signature
that prevents sending the `Scope` itself to spawned tasks.
## Solution
Changed the lifetime constraints in the single-threaded signatures from
`'env` to `'scope` to match the multi-threaded version.
This was split off from #11906.
# Objective
- Assist Bevy contributors in the creation of `bevy_color` spaces by

## Solution
Created a `pub(crate)` trait `StandardColor` which has all the
requirements for a typical color space (e.g, `Srgba`, `Color`, etc.).

## Changelog
- Implemented traits missing from certain color spaces.
## Migration Guide

This provides a new set of color types and operations for Bevy.
Fixes: #10986#1402
