# Objective
- Previously, `iter_combinations()` does not work on queries that have filters.
- Fixes#3651
## Solution
- Derived Copy on all `*Fetch<T>` structs, and manually implemented `Clone` to allow the test to pass (`.count()` does not work on `QueryCombinationIter` when `Clone` is derived)

# Objective
- Make `set_active_camera` system correctly respond to camera deletion, while preserving its correct behavior on first ever frame and any consequent frame, and with multiple cameras of the same type available in the world.
- Fixes#4227
## Solution
- Add a check that the entity referred to by `ActiveCamera` still exists in the world.
# Objective
- In glTF, mesh can be named. This named is used to be able to reference the mesh, but not as a component on the entity
- Bevy only added the node name to the parent node.
## Solution
- Also adds the name on the mesh entity if there is one.
Limitation: In glTF, it's possible to have one mesh (which can be named) corresponding to several primitives (which can't, but are the actual mesh). I added the mesh name to the entity with the `PbrBundle` matching the primitives, which means that a mesh with several primitives would all have the same name. I think this is acceptable...
# Objective
- Make it possible to use `System`s outside of the scheduler/executor without having to define logic to track new archetypes and call `System::add_archetype()` for each.
## Solution
- Replace `System::add_archetype(&Archetype)` with `System::update_archetypes(&World)`, making systems responsible for tracking their own most recent archetype generation the way that `SystemState` already does.
This has minimal (or simplifying) effect on most of the code with the exception of `FunctionSystem`, which must now track the latest `ArchetypeGeneration` it saw instead of relying on the executor to do it.

# Objective
Fixes#4193
## Solution
When resetting a node's `Interaction` to `None`, ignore any `Clicked` node because that should be handled by the mouse release check exclusively.
Remove the 'chaining' api, as it's peculiar
~~Implement the label traits for `Box<dyn ThatTrait>` (n.b. I'm not confident about this change, but it was the quickest path to not regressing)~~
Remove the need for '`.system`' when using run criteria piping
# Objective
- While animating 501 https://github.com/KhronosGroup/glTF-Sample-Models/tree/master/2.0/BrainStem, I noticed things were getting a little slow
- Looking in tracy, the system `extract_skinned_meshes` is taking a lot of time, with a mean duration of 15.17ms
## Solution
- ~~Use `Vec` instead of a `SmallVec`~~
- ~~Don't use an temporary variable~~
- Compute the affine matrix as an `Affine3A` instead
- Remove the `temp` vec
| |mean|
|---|---|
|base|15.17ms|
|~~vec~~|~~9.31ms~~|
|~~no temp variable~~|~~11.31ms~~|
|removing the temp vector|8.43ms|
|affine|13.21ms|
|all together|7.23ms|
# Objective
- Make use of storage buffers, where they are available, for clustered forward bindings to support far more point lights in a scene
- Fixes#3605
- Based on top of #4079
This branch on an M1 Max can keep 60fps with about 2150 point lights of radius 1m in the Sponza scene where I've been testing. The bottleneck is mostly assigning lights to clusters which grows faster than linearly (I think 1000 lights was about 1.5ms and 5000 was 7.5ms). I have seen papers and presentations leveraging compute shaders that can get this up to over 1 million. That said, I think any further optimisations should probably be done in a separate PR.
## Solution
- Add `RenderDevice` to the `Material` and `SpecializedMaterial` trait `::key()` functions to allow setting flags on the keys depending on feature/limit availability
- Make `GpuPointLights` and `ViewClusterBuffers` into enums containing `UniformVec` and `StorageBuffer` variants. Implement the necessary API on them to make usage the same for both cases, and the only difference is at initialisation time.
- Appropriate shader defs in the shader code to handle the two cases
## Context on some decisions / open questions
- I'm using `max_storage_buffers_per_shader_stage >= 3` as a check to see if storage buffers are supported. I was thinking about diving into 'binding resource management' but it feels like we don't have enough use cases to understand the problem yet, and it is mostly a separate concern to this PR, so I think it should be handled separately.
- Should `ViewClusterBuffers` and `ViewClusterBindings` be merged, duplicating the count variables into the enum variants?

# Objective
- Changing animation mid animation can leave the model not in its original position
- ~~The movement speed is fixed, no matter the size of the model~~
## Solution
- when changing animation, set it to its initial state and wait for one frame before changing the animation
- ~~when settings the camera controller, use the camera transform to know how far it is from the origin and use the distance for the speed~~
# Objective
The `bevy_app` crate has a lot of inconsistencies in the documentation (formatting, spelling, phrasing, consistency).
## Solution
Make it more consistent.
# Objective
- Fix#4416
- The scene has two root nodes, with the second one being the animation root
## Solution
- Check all scene root nodes, and add the `AnimationPlayer` component to nodes that are also animation roots
The scene viewer example doesn't run on wasm because it sets the asset folder to `std::env::var("CARGO_MANIFEST_DIR").unwrap()`, which isn't supported on the web.
Solution: set the asset folder to `"."` instead.
# Objective
Make `FromWorld` more useful for abstractions with a form similar to
```rs
trait FancyAbstraction {
type PreInitializedData: FromWorld;
}
```
## Solution
Add a `FromWorld` implementation for `SystemState` as well as a way to group together multiple `FromWorld` implementing types as one.
Note: I plan to follow up this PR with another to add `Local` support to exclusive systems, which should get a fair amount of use from the `FromWorld` implementation on `SystemState`.
# Objective
Avoid crashing if `RenderDevice` doesn't exist (required for headless mode).
Fixes#4392.
## Solution
Use `CompressedImageFormats::all()` if there is no `RenderDevice`.
# Objective
- Revert #4410
- `Input<T>.clear()` is the method call at the end of each frame for inputs. Clearing `pressed` in it mean that checking if a key is pressed will always return false
# Objective
- Fixes#1616, fixes#2225
- Let user specify an anchor for a sprite
## Solution
- Add an enum for an anchor point for most common values, with a variant for a custom point
- Defaults to Center to not change current behaviour

Fixes#3408#3001 also solves this but I dont see it getting merged any time soon so...
# Objective
make bevy ecs a lil bit less unsound
## Solution
make `EntityMut::get_component_mut` return borrows from self instead of `'w`
# Objective
- `Local`s can no longer be accessed outside of their creating system, but these docs say they can be.
- There's also little reason to have a pure wrapper type for `Local`s; they can just use the real type. The parameter name should be sufficiently documenting.
# Objective
- Animation is using `Name` to be able to address nodes in an entity free way
- When loading random animated gltf files, I noticed some had animations without names sometimes
## Solution
- Add default names to all nodes
# Objective
- Fixes https://github.com/bevyengine/bevy/issues/2096
## Solution
- This PR enables the drag-and-drop feature for winit on windows again, as the collision issue between cpal and winit has been fixed in https://github.com/RustAudio/cpal/pull/597. I confirmed the drag and drop example working on windows 10 with this change.
- ~~It also bumps the rodio version, though this is not strictly necessary.~~
# Objective
- While playing with animated models, I noticed some were a little off
## Solution
- Some animations curves only have one keyframe, they are used to set a transform to a given value
- Those were ignored as we're never exactly at the ts 0.0 of an animation. going there explicitly (`.set_elapsed(0.0).pause()`) would crash
- Special case this as there isn't much to animate in this case
https://en.wikipedia.org/wiki/HSL_and_HSV#From_RGB
# Objective
Fixes#4382
## Solution
- Describe the solution used to achieve the objective above.
Fixed conversion formula to account for red and green component being max and equal
---
## Changelog
Fixed RGB -> HSL colorspace conversion
## Migration Guide

# Objective
- Only move the camera when explicitly wanted, otherwise the camera goes crazy if the cursor isn't already in the middle of the window when it opens.
## Solution
- Check if the Left mouse button is pressed before updating the mouse delta
- Input is configurable
# Objective
- Part of the splitting process of #3503.
## Solution
- Remove the `face_toward.rs` file containing the `FaceToward` trait.
## Reasons
- It is unused inside of `bevy`.
- The method `Mat4::face_toward` of the trait is identical to `Mat4::look_at_rh` (see https://docs.rs/glam/latest/glam/f32/struct.Mat4.html#method.look_at_rh).
- Discussion in #3503.
## Changelog
### Removed
- The `FaceToward` trait got removed.
## Migration Guide
- The `FaceToward` trait got removed. To migrate you just have to change every occurrence of `Mat4::face_toward` to `Mat4::look_at_rh`.
The example was broken in #3635 when the `ActiveCamera` logic was introduced, after which there could only be one active `Camera3d` globally.
Ideally there could be one `Camera3d` per render target, not globally, but that isn't the case yet.
To fix the example, we need to
- don't use `Camera3d` twice, add a new `SecondWindowCamera3d` marker
- add the `CameraTypePlugin::<SecondWindowCamera3d>`
- extract the correct `RenderPhase`s
- add a 3d pass driver node for the secondary camera
Fixes#4378

# Objective
- Since #4224, using labels which only refer to one system doesn't make sense.
## Solution
- Remove some of those.
## Future work
- We should remove the ability to use strings as system labels entirely. I haven't in this PR because there are tests which use this, and that's a lot of code to change.
- The only use cases for labels are either intra-crate, which use #4224, or inter-crate, which should either use #4224 or explicit types. Neither of those should use strings.

<p>This change adds a minimum runner version(node12 -> node16), which can break users using an out-of-date/fork of the runner. This would be most commonly affecting users on GHES 3.3 or before, as those runners do not support node16 actions and they can use actions from github.com via <a href="https://docs.github.com/en/enterprise-server@3.0/admin/github-actions/managing-access-to-actions-from-githubcom/enabling-automatic-access-to-githubcom-actions-using-github-connect">github connect</a> or manually copying the repo to their GHES instance.</p>
</li>
<li>
<p>Few dependencies and cache action usage examples have also been updated.</p>
</li>
</ul>

</ul>
<h2>v2.1.3</h2>
<ul>
<li>Upgrades <code>@actions/core</code> to v1.2.6 for <a href="https://github.com/advisories/GHSA-mfwh-5m23-j46w">CVE-2020-15228</a>. This action was not using the affected methods.</li>
<li>Fix error handling in <code>uploadChunk</code> where 400-level errors were not being detected and handled correctly</li>
</ul>
<h2>v2.1.2</h2>
<ul>
<li>Adds input to limit the chunk upload size, useful for self-hosted runners with slower upload speeds</li>
<li>No-op when executing on GHES</li>
</ul>
<h2>v2.1.1</h2>

# Objective
- std's new APIs do the same thing as `Query::get_multiple_mut`, but are called `get_many`: https://github.com/rust-lang/rust/pull/83608
## Solution
- Find and replace `get_multiple` with `get_many`
# Objective
Make it so that loading in a mesh without normals that is not a `TriangleList` succeeds.
## Solution
Flat normals can only be calculated on a mesh made of triangles.
Check whether the mesh is a `TriangleList` before trying to compute missing normals.
## Additional changes
The panic condition in `duplicate_vertices` did not make sense to me. I moved it to `compute_flat_normals` where the algorithm would produce incorrect results if the mesh is not a `TriangleList`.

# Objective
- Clarify `RemovedComponents` are flushed in `CoreStage::Last` and systems relying on that should run before that stage
## Solution
- Update `RemovedComponents` doc comment
# Objective
CONTRIBUTING.md contains links to pages that are restricted to Bevy Engine Org members.
First time contributors who read CONTRIBUTING.md will end up on a confusing 404 page if they try to follow the link.
Relevant discussion: #4365
## Solution
Replace links with directions to the Triage Team page.
### Note
I'm not sure if `assign themselves as a member` is accurate. I think that is what `automatically request membership` was referring to, but i can't check for myself 😉

# Objective
make bevy ecs a lil bit less unsound
## Solution
make unsound API unsafe so that there is an unsafe block to blame:
```rust
use bevy_ecs::prelude::*;
#[derive(Debug, Component)]
struct Foo(u8);
fn main() {
let mut world = World::new();
let e1 = world.spawn().id();
let e2 = world.spawn().insert(Foo(2)).id();
world.entities_mut().meta[0] = world.entities_mut().meta[1].clone();
let foo = world.entity(e1).get::<Foo>().unwrap();
// whoo i love having components i dont have
dbg!(foo);
}
```
This is not _strictly_ speaking UB, however:
- `Query::get_multiple` cannot work if this is allowed
- bevy_ecs is a pile of unsafe code whose soundness generally depends on the world being in a "correct" state with "no funny business" so it seems best to disallow this
- it is trivial to get bevy to panic inside of functions with safety invariants that have been violated (the entity location is not valid)
- it seems to violate what the safety invariant on `Entities::flush` is trying to ensure
# Objective
An entity spawned with `MaterialMesh2dBundle<M>` cannot be saved and spawned using `DynamicScene` because the `Mesh2dHandle` component does not `impl Reflect`.
## Solution
Add `#[derive(Reflect)]` and `#[reflect(Component)]` to `Mesh2dHandle`, and call `register_type` in `SpritePlugin`. Also add `#[derive(Debug)]` since I'm touching the `derive`s anyway.
# Objective
Animation with shadows crashes with:
```
thread 'main' panicked at 'wgpu error: Validation Error
Caused by:
In Device::create_render_pipeline
note: label = `shadow_pipeline`
error matching VERTEX shader requirements against the pipeline
shader global ResourceBinding { group: 1, binding: 1 } is not available in the layout pipeline layout
visibility flags don't include the shader stage
```
Animation with wireframe crashes with:
```
thread 'main' panicked at 'wgpu error: Validation Error
Caused by:
In Device::create_render_pipeline
note: label = `opaque_mesh_pipeline`
error matching VERTEX shader requirements against the pipeline
shader global ResourceBinding { group: 2, binding: 0 } is not available in the layout pipeline layout
binding is missing from the pipeline layout
```
## Solution
- Fix the bindings
# Objective
- The inability to have multiple active mutable borrows into a query is a common source of borrow-checker pain for users.
- This is a pointless restriction if and only if we can guarantee that the entities they are accessing are unique.
- This could already by bypassed with get_unchecked, but that is an extremely unsafe API.
- Closes https://github.com/bevyengine/bevy/issues/2042.
## Solution
- Add `get_multiple`, `get_multiple_mut` and their unchecked equivalents (`multiple` and `multiple_mut`) to `Query` and `QueryState`.
- Improve the `QueryEntityError` type to provide more useful error information.
## Changelog
- Added `get_multiple`, `get_multiple_mut` and their unchecked equivalents (`multiple` and `multiple_mut`) to Query and QueryState.
## Migration Guide
- The `QueryEntityError` enum now has a `AliasedMutability variant, and returns the offending entity.
## Context
This is a fresh attempt at #3333; rebasing was behaving very badly and it was important to rebase on top of the recent query soundness fixes. Many thanks to all the reviewers in that thread, especially @BoxyUwU for the help with lifetimes.
## To-do
- [x] Add compile fail tests
- [x] Successfully deduplicate code
- [x] Decide what to do about failing doc tests
- [x] Get some reviews for lifetime soundness
# Objective
Add a system parameter `ParamSet` to be used as container for conflicting parameters.
## Solution
Added two methods to the SystemParamState trait, which gives the access used by the parameter. Did the implementation. Added some convenience methods to FilteredAccessSet. Changed `get_conflicts` to return every conflicting component instead of breaking on the first conflicting `FilteredAccess`.

# Objective
Cleans up some duplicated color -> u32 conversion code in `bevy_sprite` and `bevy_ui`
## Solution
Use `as_linear_rgba_u32` which was added recently by #4088
# Objective
Fixes#4344.
## Solution
Add a new component `Text2dBounds` to `Text2dBundle` that specifies the maximum width and height of text. Text will wrap according to this size.
