# Objective
Some of the reflection impls for container types had unnecessary `Clone` bounds on their generic arguments. These come from before `FromReflect` when types were instead bound by `Reflect + Clone`. With `FromReflect` this is no longer necessary.
## Solution
Removed all leftover `Clone` bounds from types that use `FromReflect` instead.
## Note
I skipped `Result<T, E>`, `HashSet<T>`, and `Range<T>` since those do not use `FromReflect`. This should probably be handled in a separate PR since it would be a breaking change.
---
## Changelog
- Remove unnecessary `Clone` bounds on reflected containers
# Objective
#5658 made it so that `FromReflect` was used as the bound for `T` in `Option<T>`. However, it did not use this change effectively for the implementation of `Reflect::apply` (it was still using `take`, which would fail for Dynamic types).
Additionally, the changes were not consistent with other methods within the file, such as the ones for `Vec<T>` and `HashMap<K, V>`.
## Solution
Update `Option<T>` to fallback on `FromReflect` if `take` fails, instead of wholly relying on one or the other.
I also chose to update the error messages, as they weren't all too descriptive before.
---
## Changelog
- Use `FromReflect::from_reflect` as a fallback in the `Reflect::apply` implementation for `Option<T>`
# Objective
`SmallVec<T>` was missing a `GetTypeRegistration` impl.
## Solution
Added a `GetTypeRegistration` impl.
---
## Changelog
* Added a `GetTypeRegistration` impl for `SmallVec<T>`
Type registrations were only present for some of the `bevy_math` types, and missing for others. This is a very strange inconsistency, given that they all impl `Reflect` and `FromReflect`. In practice, this means these types cannot be used in scenes.
In particular, this is especially problematic, because `Affine3A` is one of the missing types, and it is now used in `GlobalTransform`. Trying to create a bevy scene that contains `GlobalTransform`s results in an error due to the missing type registration.
# Objective
- While generating https://github.com/jakobhellermann/bevy_reflect_ts_type_export/blob/main/generated/types.ts, I noticed that some types that implement `Reflect` did not register themselves
- `Viewport` isn't reflect but can be (there's a TODO)
## Solution
- register all reflected types
- derive `Reflect` for `Viewport`
## Changelog
- more types are not registered in the type registry
- remove `Serialize`, `Deserialize` impls from `Viewport`
I also decided to remove the `Serialize, Deserialize` from the `Viewport`, since they were (AFAIK) only used for reflection, which now is done without serde. So this is technically a breaking change for people who relied on that impl directly.
Personally I don't think that every bevy type should implement `Serialize, Deserialize`, as that would lead to a ton of code generation that mostly isn't necessary because we can do the same with `Reflect`, but if this is deemed controversial I can remove it from this PR.
## Migration Guide
- `KeyCode` now implements `Reflect` not as `reflect_value`, but with proper struct reflection. The `Serialize` and `Deserialize` impls were removed, now that they are no longer required for scene serialization.
# Objective
Fix a nasty system ordering bug between `update_frusta` and `camera_system` that lead to incorrect frustum s, leading to excessive culling and extremely hard-to-debug visual glitches
## Solution
- add explicit system ordering
# Objective
Very small convenience constructors added to `Size`.
Does not change current examples too much but I'm working on a rather complex UI use-case where this cuts down on some extra typing :)
# Objective
- Fixes#4451
## Solution
- Conditionally compile entity ID cursor as `AtomicI32` when compiling on a platform that does not support 64-bit atomics.
- This effectively raises the MSRV to 1.60 as it uses a `#[cfg]` that was only just stabilized there. (should this be noted in changelog?)
---
## Changelog
- Added `bevy_ecs` support for platforms without 64-bit atomic ints
## Migration Guide
N/A
# Objective
- Morten Mikkelsen clarified that the world normal and tangent must be normalized in the vertex stage and the interpolated values must not be normalized in the fragment stage. This is in order to match the mikktspace approach exactly.
- Fixes#5514 by ensuring the tangent basis matrix (TBN) is orthonormal
## Solution
- Normalize the world normal in the vertex stage and not the fragment stage
- Normalize the world tangent xyz in the vertex stage
- Take into account the sign of the determinant of the local to world matrix when calculating the bitangent
---
## Changelog
- Fixed - scaling a model that uses normal mapping now has correct lighting again
# Objective
- Fixes#5365
- The `assert!()` when the resource from `World::resource_scope` is inserted into the world is not descriptive.
## Solution
- Add more context to the assert inside of `World::resource_scope` when the `FnOnce` param inserts the resource.
# Objective
`FromReflect` is a commonly used component to the Reflect API. It's required as a bound for reflecting things like `Vec<T>` and `HashMap<K, V>` and is generally useful (if not necessary) to derive on most structs or enums.
Currently, however, it is not exported in `bevy_reflect`'s prelude. This means a module that uses `bevy_reflect` might have the following two lines:
```rust
use bevy_reflect::prelude::*;
use bevy_reflect::FromReflect;
```
Additionally, users of the full engine might need to put:
```rust
use bevy::prelude::*;
use bevy::reflect::FromReflect;
```
## Solution
Add `FromReflect` to the prelude of `bevy_reflect`.
---
## Changelog
- Added `FromReflect` to the prelude of `bevy_reflect`
# Objective
- Similar to `SystemChangeTick`, probably somewhat useful for debugging messages.
---
## Changelog
- Added `SystemName` which copies the `SystemMeta::name` field so it can be accessed within a system.
Probably a copy-paste error, but `Add<Color>` and `AddAssign<Color>` should use `rhs.as_hlsa_f32()` instead of `rhs.as_linear_rgba_f32()` when the LHS is a `Color::Hsla`. Fixes#5543.

# Objective
The reflection impls on `Option<T>` have the bound `T: Reflect + Clone`. This means that using `FromReflect` requires `Clone` even though we can normally get away with just `FromReflect`.
## Solution
Update the bounds on `Option<T>` to match that of `Vec<T>`, where `T: FromReflect`.
This helps remove a `Clone` implementation that may be undesired but added for the sole purpose of getting the code to compile.
---
## Changelog
* Reflection on `Option<T>` now has `T` bound by `FromReflect` rather than `Reflect + Clone`
* Added a `FromReflect` impl for `Instant`
## Migration Guide
If using `Option<T>` with Bevy's reflection API, `T` now needs to implement `FromReflect` rather than just `Clone`. This can be achieved easily by simply deriving `FromReflect`:
```rust
// OLD
#[derive(Reflect, Clone)]
struct Foo;
let reflected: Box<dyn Reflect> = Box::new(Some(Foo));
// NEW
#[derive(Reflect, FromReflect)]
struct Foo;
let reflected: Box<dyn Reflect> = Box::new(Some(Foo));
```
> Note: You can still derive `Clone`, but it's not required in order to compile.
# Objective
Rust 1.63 resolved [an issue](https://github.com/rust-lang/rust/issues/83701) that prevents you from combining explicit generic arguments with `impl Trait` arguments.
Now, we no longer need to use dynamic dispatch to work around this.
## Migration Guide
The methods `Schedule::get_stage` and `get_stage_mut` now accept `impl StageLabel` instead of `&dyn StageLabel`.
### Before
```rust
let stage = schedule.get_stage_mut::<SystemStage>(&MyLabel)?;
```
### After
```rust
let stage = schedule.get_stage_mut::<SystemStage>(MyLabel)?;
```
# Objective
- Replace the square with a circle in the breakout example.
- Fixes#4324, adopted from #4682 by @shaderduck.
## Solution
- Uses the Mesh2D APIs to draw a circle. The collision still uses the AABB algorithm, but it seems to be working fine, and I haven't seen any odd looking cases.
# Objective
This PR changes it possible to use vertex colors without a texture using the bevy_sprite ColorMaterial.
Fixes#5679
## Solution
- Made multiplication of the output color independent of the COLOR_MATERIAL_FLAGS_TEXTURE_BIT bit
- Extended mesh2d_vertex_color_texture example to show off both vertex colors and tinting
Not sure if extending the existing example was the right call but it seems to be reasonable to me.
I couldn't find any tests for the shaders and I think adding shader testing would be beyond the scope of this PR. So no tests in this PR. 😬

# Objective
While poking around the hierarchy code, I wondered why some asserts in tests were duplicated.
Some git blame later, I found out that commit ( 8eb0440f1e ) added already existing asserts while removing others.
## Solution
Remove the duplicated asserts.
# Objective
When an invalid attribute is inserted and the LogPlugin is not enabled the full error is not printed which means makes it hard to diagnose.
## Solution
- Always print the full message in the panic.
## Notes
I originally had a separate error log because I wanted to make it clearer for users, but this is probably causing more issues than necessary.
# Objective
Remove unused `enum DepthCalculation` and its usages. This was used to compute visible entities in the [old renderer](db665b96c0/crates/bevy_render/src/camera/visible_entities.rs), but is now unused.
## Solution
`sed 's/DepthCalculation//g'`
---
## Changelog
### Changed
Removed `bevy_render:📷:DepthCalculation`.
## Migration Guide
Remove references to `bevy_render:📷:DepthCalculation`, such as `use bevy_render:📷:DepthCalculation`. Remove `depth_calculation` fields from Projections.
# Objective
The `deny.toml` file defines some crates that are skipped for duplicate dependency detection, because the issues are deeper in the dependency tree and not easily fixable.
However, two of those exceptions are no longer necessary.
## Solution
Remove `hashbrown` and `mio` from the skipped crates, according to `cargo deny check` this is no longer needed.
# Objective
Fixes#5668.
The Rust version used in the CI `build` step previously depended on the default Rust version defined by GitHub in the Ubuntu image: <https://github.com/actions/runner-images/blob/main/images/linux/Ubuntu2004-Readme.md#rust-tools>
This currently doesn't allow us to use Rust 1.63 features until this version is updated.
## Solution
We now use the `actions-rs/toolchain@v1` action to always use the latest stable Rust version.
This is already used for other CI jobs that we have.
# Objective
Make CI pass on bevy main.
Update to rust-1.63, updated clippy to 1.63 which introduced the following enhancements:
- [undocumented_unsafe_blocks](https://rust-lang.github.io/rust-clippy/master/index.html#undocumented_unsafe_blocks): Now also lints on unsafe trait implementations
This caught two incorrectly written ( but existing) safety comments for unsafe traits.
## Solution
Fix the comment to use `SAFETY:`
# Objective
While trying out the lint `unsafe_op_in_unsafe_fn` I noticed that `insert_resource_by_id` didn't drop the old value if it already existed, and reimplemented `Column::replace` manually for no apparent reason.
## Solution
- use `Column::replace` and add a test expecting the correct drop count
---
## Changelog
- `World::insert_resource_by_id` will now correctly drop the old resource value, if one already existed
# Objective
- The `Display` impl for `ReflectPathError` is pretty unspecific (e.g. `the current struct doesn't have a field with the given name`
- it has info for better messages available
## Solution
- make the display impl more descriptive by including values from the type
# Objective
- `ReflectMut` served no purpose that wasn't met by `Mut<dyn Reflect>` which is easier to understand since you have to deal with fewer types
- there is another `ReflectMut` type that could be confused with this one
## Solution/Changelog
- relax `T: ?Sized` bound in `Mut<T>`
- replace all instances of `ReflectMut` with `Mut<dyn Reflect>`
# Objective
Provide a safe API to access an `EntityMut`'s `World`.
## Solution
* Add `EntityMut::into_world_mut` for safe access to the entity's world.
---
## Changelog
* Add `EntityMut::into_world_mut` for safe access to the entity's world.
# Objective
`ShaderData` is marked as public, but is an internal type only used by one other
internal type, so it should be made private.
## Solution
`ShaderData` is only used in `ShaderCache`, and the latter is private,
so there is no need to make the former public. This change removes the
`pub` keyword from `ShaderData`, hidding it as the implementation detail
it is.
Split from #5600
# Objective
- I often have UI nodes that are completely transparent and just for organisation
- Don't render them
- I doesn't bring a lot of improvements, but it doesn't add a lot of complexity either
*This PR description is an edited copy of #5007, written by @alice-i-cecile.*
# Objective
Follow-up to https://github.com/bevyengine/bevy/pull/2254. The `Resource` trait currently has a blanket implementation for all types that meet its bounds.
While ergonomic, this results in several drawbacks:
* it is possible to make confusing, silent mistakes such as inserting a function pointer (Foo) rather than a value (Foo::Bar) as a resource
* it is challenging to discover if a type is intended to be used as a resource
* we cannot later add customization options (see the [RFC](https://github.com/bevyengine/rfcs/blob/main/rfcs/27-derive-component.md) for the equivalent choice for Component).
* dependencies can use the same Rust type as a resource in invisibly conflicting ways
* raw Rust types used as resources cannot preserve privacy appropriately, as anyone able to access that type can read and write to internal values
* we cannot capture a definitive list of possible resources to display to users in an editor
## Notes to reviewers
* Review this commit-by-commit; there's effectively no back-tracking and there's a lot of churn in some of these commits.
*ira: My commits are not as well organized :')*
* I've relaxed the bound on Local to Send + Sync + 'static: I don't think these concerns apply there, so this can keep things simple. Storing e.g. a u32 in a Local is fine, because there's a variable name attached explaining what it does.
* I think this is a bad place for the Resource trait to live, but I've left it in place to make reviewing easier. IMO that's best tackled with https://github.com/bevyengine/bevy/issues/4981.
## Changelog
`Resource` is no longer automatically implemented for all matching types. Instead, use the new `#[derive(Resource)]` macro.
## Migration Guide
Add `#[derive(Resource)]` to all types you are using as a resource.
If you are using a third party type as a resource, wrap it in a tuple struct to bypass orphan rules. Consider deriving `Deref` and `DerefMut` to improve ergonomics.
`ClearColor` no longer implements `Component`. Using `ClearColor` as a component in 0.8 did nothing.
Use the `ClearColorConfig` in the `Camera3d` and `Camera2d` components instead.

# Objective
The `LICENSE` file in the root directory was removed in #4966. This breaks the license shield link in the README.
## Solution
I changed the link to instead point at the license section of the readme on the main repo page. I think this is better than a 404, but I am unsure as to if it's the best solution. As such feedback is appreciated.
# Objective
`bevy::render::texture::ImageSettings` was added to prelude in #5566, so these `use` statements are unnecessary and the examples can be made a bit more concise.
## Solution
Remove `use bevy::render::texture::ImageSettings`
# Objective
- I wanted to have controls independent from keyboard layout and found that bevy doesn't have a proper implementation for that
## Solution
- I created a `ScanCode` enum with two hundreds scan codes and updated `keyboard_input_system` to include and update `ResMut<Input<ScanCode>>`
- closes both https://github.com/bevyengine/bevy/issues/2052 and https://github.com/bevyengine/bevy/issues/862

# Objective
- Fixes#5544
- Part of the splitting process of #3692.
## Solution
- Document everything in the `gamepad.rs` file.
- Add a doc example for mocking gamepad input.
---
## Changelog
- Added and updated the documentation inside of the `gamepad.rs` file.
# Objective
- Similar to #5512 , the `View` struct definition in the shaders in `bevy_sprite` and `bevy_ui` were out of sync with the rust-side `ViewUniform`. Only `view_proj` was being used and is the first member and as those shaders are not customisable it makes little difference in practice, unlike for `Mesh2d`.
## Solution
- Sync shader `View` struct definition in `bevy_sprite` and `bevy_ui` with the correct definition that matches `ViewUniform`

Change frametimediagnostic from seconds to milliseconds because this will always be less than one seconds and is the common diagnostic display unit for game engines.
## Solution
- multiplied the existing value by 1000

# Objective
In Bevy 0.8, the default filter mode was changed to linear (#4465). I believe this is a sensible default, but it's also very common to want to use point filtering (e.g. for pixel art games).
## Solution
I am proposing including `bevy_render::texture::ImageSettings` in the Bevy prelude so it is more ergonomic to change the filtering in such cases.
---
## Changelog
### Added
- Added `bevy_render::texture::ImageSettings` to prelude.
