# Objective
- Fixes#7636.
## Solution
`apply_state_transitions::<S>` runs in `CoreSet::StateTransitions` which is already scheduled before `CoreSet::Update`. Therefore explicitly scheduling `OnUpdate` after `apply_state_transitions::<S>` is not necessary.
# Objective
- Fixes#7442.
## Solution
- Added `report_sets` option to `ScheduleBuildSettings` like described in the linked issue.
The output of the `3d_scene` example when reporting ambiguities with `report_sets` and `use_shortnames` set to `true` (and with #7755 applied) now looks like this:
```
82 pairs of systems with conflicting data access have indeterminate execution order. Consider adding `before`, `after`, or `ambiguous_with` relationships between these:

# Objective
While working on #7442 i discovered that `get_short_name` does not work well with sub paths after closing brackets. It currently turns `bevy_asset::assets::Assets<bevy_scene::dynamic_scene::DynamicScene>::asset_event_system` into `Assets<DynamicScene>asset_event_system`. This PR fixes that.
## Solution
- Retain `::` after a closing bracket like `>`, `)` or `]`.
- Add a test for all sub path after closing bracket cases.
# Objective
- Add basic spatial audio support to Bevy
- this is what rodio supports, so no HRTF, just simple stereo channel manipulation
- no "built-in" ECS support: `Emitter` and `Listener` should be components that would automatically update the positions
This PR goal is to just expose rodio functionality, made possible with the recent update to rodio 0.16. A proper ECS integration opens a lot more questions, and would probably require an RFC
Also updates rodio and fixes#6122
# Objective
Allow using `Local<WorldId>` in systems.
## Solution
- Describe the solution used to achieve the objective above.
---
## Changelog
+ `WorldId` now implements the `FromWorld` trait.
# Objective
- Nothing render
```
ERROR bevy_render::render_resource::pipeline_cache: failed to process shader: Invalid shader def definition for '_import_path': bevy_pbr
```
## Solution
- Fix define regex so that it must have one whitespace after `define`
# Objective
- Fixes#7494
- It is now possible to define a ShaderDef from inside a shader. This can be useful to centralise a value, or making sure an import is only interpreted once
## Solution
- Support `#define <SHADERDEF_NAME> <optional value>`
# Objective
- ambiguities bad
## Solution
- solve ambiguities
- by either ignoring (e.g. on `queue_mesh_view_bind_groups` since `LightMeta` access is different)
- by introducing a dependency (`prepare_windows -> prepare_*` because the latter use the fallback Msaa)
- make `prepare_assets` public so that we can do a proper `.after`
# Objective
Currently, it is quite awkward to use the `pbr` function in a custom shader without binding a mesh bind group.
This is because the `pbr` function depends on the `MESH_FLAGS_SHADOW_RECEIVER_BIT` flag.
## Solution
I have removed this dependency by adding the flag as a parameter to the `PbrInput` struct.
I am not sure if this is the ideal solution since the mesh flag indicates both `MESH_FLAGS_SIGN_DETERMINANT_MODEL_3X3_BIT` and `MESH_FLAGS_SHADOW_RECEIVER_BIT`.
The former seems to be unrelated to PBR. Maybe the flag should be split.
# Objective
- Fix the environment map shader not working under webgl due to textureNumLevels() not being supported
- Fixes https://github.com/bevyengine/bevy/issues/7722
## Solution
- Instead of using textureNumLevels(), put an extra field in the GpuLights uniform to store the mip count
# Objective
Splits tone mapping from https://github.com/bevyengine/bevy/pull/6677 into a separate PR.
Address https://github.com/bevyengine/bevy/issues/2264.
Adds tone mapping options:
- None: Bypasses tonemapping for instances where users want colors output to match those set.
- Reinhard
- Reinhard Luminance: Bevy's exiting tonemapping
- [ACES](https://github.com/TheRealMJP/BakingLab/blob/master/BakingLab/ACES.hlsl) (Fitted version, based on the same implementation that Godot 4 uses) see https://github.com/bevyengine/bevy/issues/2264
- [AgX](https://github.com/sobotka/AgX)
- SomewhatBoringDisplayTransform
- TonyMcMapface
- Blender Filmic
This PR also adds support for EXR images so they can be used to compare tonemapping options with reference images.
## Migration Guide
- Tonemapping is now an enum with NONE and the various tonemappers.
- The DebandDither is now a separate component.

…top sort. reduce mem alloc
# Objective
- Reduce alloc count.
- Improve code quality.
## Solution
- use `TarjanScc::run` directly, which calls a closure with each scc, in closure, we can detect cycles and flatten nodes
# Objective
`ChangeTrackers<>` is a `WorldQuery` type that lets you access the change ticks for a component. #7097 has added `Ref<>`, which gives access to a component's value in addition to its change ticks. Since bevy's access model does not separate a component's value from its change ticks, there is no benefit to using `ChangeTrackers<T>` over `Ref<T>`.
## Solution
Deprecate `ChangeTrackers<>`.
---
## Changelog
* `ChangeTrackers<T>` has been deprecated. It will be removed in Bevy 0.11.
## Migration Guide
`ChangeTrackers<T>` has been deprecated, and will be removed in the next release. Any usage should be replaced with `Ref<T>`.
```rust
// Before (0.9)
fn my_system(q: Query<(&MyComponent, ChangeTrackers<MyComponent>)>) {
for (value, trackers) in &q {
if trackers.is_changed() {
// Do something with `value`.
}
}
}
// After (0.10)
fn my_system(q: Query<Ref<MyComponent>>) {
for value in &q {
if value.is_changed() {
// Do something with `value`.
}
}
}
```
# Objective
- Updates list of plugins and feature information in `DefaultPlugins` doc comment
- Solve the short term issue of https://github.com/bevyengine/bevy/issues/7332
## Solution
- Update doc comment to reflect current implementation
- Sort plugins by appearance in implementation
# Objective
Fixes#7736
## Solution
Implement the `SystemParam` trait for `WorldId`
## Changelog
- `WorldId` can now be taken as a system parameter and will return the id of the world the system is running in
# Objective
Closes#7573
- Make `StartupSet` a base set
## Solution
- Add `#[system_set(base)]` to the enum declaration
- Replace `.in_set(StartupSet::...)` with `.in_base_set(StartupSet::...)`
**Note**: I don't really know what I'm doing and what exactly the difference between base and non-base sets are. I mostly opened this PR based on discussion in Discord. I also don't really know how to test that I didn't break everything. Your reviews are appreciated!
---
## Changelog
- `StartupSet` is now a base set
## Migration Guide
`StartupSet` is now a base set. This means that you have to use `.in_base_set` instead of `.in_set`:
### Before
```rs
app.add_system(foo.in_set(StartupSet::PreStartup))
```
### After
```rs
app.add_system(foo.in_base_set(StartupSet::PreStartup))
```
# Objective
-0.0 should typically be treated exactly the same as 0.0, but this assertion was rejecting it while allowing 0.0. The `Duration` API handles this correctly (on recent Rust versions) and returns a zero `Duration` for both -0.0 and 0.0.
## Solution
Check for `ratio >= 0.0`, which is true if `ratio` is `-0.0`.
---
## Changelog
Allow relative speed of -0.0 in the `Time::set_relative_speed_fXX` methods.
# Objective
- Fixes#7659.
## Solution
- This PR extracted the `distributive_run_if` part of #7676, because it does not require the controversial introduction of anonymous system sets.
- The distinctive name should make the user aware about the differences between `IntoSystemConfig::run_if` and `IntoSystemConfigs::distributive_run_if`.
- The documentation explains in detail the consequences of using the API and possible pit falls when using it.
- A test demonstrates the possibility of changing the condition result, resulting in some of the systems not being run.
---
## Changelog
### Added
- Add `distributive_run_if` to `IntoSystemConfigs` to enable adding a run condition to each system when using `add_systems`.
# Objective
`bevy_reflect` can be a moderately complex crate to try and understand. It has many moving parts, a handful of gotchas, and a few subtle contracts that aren't immediately obvious to users and even other contributors.
The current README does an okay job demonstrating how the crate can be used. However, the crate's actual documentation should give a better overview of the crate, its inner-workings, and show some of its own examples.
## Solution
Added crate-level documentation that attempts to summarize the main parts of `bevy_reflect` into small sections.
This PR also updates the documentation for:
- `Reflect`
- `FromReflect`
- The reflection subtraits
- Other important types and traits
- The reflection macros (including the derive macros)
- Crate features
### Open Questions
1. ~~Should I update the docs for the Dynamic types? I was originally going to, but I'm getting a little concerned about the size of this PR 😅~~ Decided to not do this in this PR. It'll be better served from its own PR.
2. Should derive macro documentation be moved to the trait itself? This could improve visibility and allow for better doc links, but could also clutter up the trait's documentation (as well as not being on the actual derive macro's documentation).
### TODO
- [ ] ~~Document Dynamic types (?)~~ I think this should be done in a separate PR.
- [x] Document crate features
- [x] Update docs for `GetTypeRegistration`
- [x] Update docs for `TypeRegistration`
- [x] Update docs for `derive_from_reflect`
- [x] Document `reflect_trait`
- [x] Document `impl_reflect_value`
- [x] Document `impl_from_reflect_value`
---
## Changelog
- Updated documentation across the `bevy_reflect` crate
- Removed `#[module]` helper attribute for `Reflect` derives (this is not currently used)
## Migration Guide
- Removed `#[module]` helper attribute for `Reflect` derives. If your code is relying on this attribute, please replace it with either `#[reflect]` or `#[reflect_value]` (dependent on use-case).

follow-up to https://github.com/bevyengine/bevy/pull/7716
# Objective
System access is only populated in `System::initialize`, so without calling `initialize` it's actually impossible to see most ambiguities.
## Solution
- make `initialize` public. The method is idempotent, so calling it multiple times doesn't hurt
# Objective
Continuation of https://github.com/bevyengine/bevy/pull/5719
Now that we have a definable type for the iterator.
---
## Changelog
- Implemented IntoIterator for EventReader so you can now do `&mut reader` instead of `reader.iter()` for events.
# Objective
- bevy_ggrs uses `reflect_hash` in order to produce checksums for its world snapshots. These checksums are sent between clients in order to detect desyncronization.
- However, since we currently use `async::AHasher` with the `std` feature, this means that hashes will always be different for different peers, even if the state is identical.
- This means bevy_ggrs needs a way to get a deterministic (fixed) hash.
## Solution
- ~~Add a feature to use `bevy_utils::FixedState` for the hasher used by bevy_reflect.~~
- Always use `bevy_utils::FixedState` for initializing the bevy_reflect hasher.
---
## Changelog
- bevy_reflect now uses a fixed state for its hasher, which means the output of `Reflect::reflect_hash` is now deterministic across processes.
# Objective
Fix#7440. Fix#7441.
## Solution
* Remove builder functions on `ScheduleBuildSettings` in favor of public fields, move docs to the fields.
* Add `use_shortnames` and use it in `get_node_name` to feed it through `bevy_utils::get_short_name`.
# Objective
Allow for creating pipelines that use push constants. To be able to use push constants. Fixes#4825
As of right now, trying to call `RenderPass::set_push_constants` will trigger the following error:
```
thread 'main' panicked at 'wgpu error: Validation Error
Caused by:
In a RenderPass
note: encoder = `<CommandBuffer-(0, 59, Vulkan)>`
In a set_push_constant command
provided push constant is for stage(s) VERTEX | FRAGMENT | VERTEX_FRAGMENT, however the pipeline layout has no push constant range for the stage(s) VERTEX | FRAGMENT | VERTEX_FRAGMENT
```
## Solution
Add a field push_constant_ranges to` RenderPipelineDescriptor` and `ComputePipelineDescriptor`.
This PR supersedes #4908 which now contains merge conflicts due to significant changes to `bevy_render`.
Meanwhile, this PR also made the `layout` field of `RenderPipelineDescriptor` and `ComputePipelineDescriptor` non-optional. If the user do not need to specify the bind group layouts, they can simply supply an empty vector here. No need for it to be optional.
---
## Changelog
- Add a field push_constant_ranges to RenderPipelineDescriptor and ComputePipelineDescriptor
- Made the `layout` field of RenderPipelineDescriptor and ComputePipelineDescriptor non-optional.
## Migration Guide
- Add push_constant_ranges: Vec::new() to every `RenderPipelineDescriptor` and `ComputePipelineDescriptor`
- Unwrap the optional values on the `layout` field of `RenderPipelineDescriptor` and `ComputePipelineDescriptor`. If the descriptor has no layout, supply an empty vector.

# Objective
Fixes#7295
Should we maybe default to 4x if 2x/8x is selected but not supported?
---
## Changelog
- Added 2x and 8x sample counts for MSAA.
# Objective
- Environment maps use these formats, and in the future rendering LUTs will need textures loaded by default in the engine
## Solution
- Make ktx2 and zstd part of the default feature
- Let examples assume these features are enabled
---
## Changelog
- `ktx2` and `zstd` are now party of bevy's default enabled features
## Migration Guide
- If you used the `ktx2` or `zstd` features, you no longer need to explicitly enable them, as they are now part of bevy's default enabled features
# Objective
The type `SyncCell<T>` (added in #5483) is used to force any wrapped type to be `Sync`, by only allowing exclusive access to the wrapped value. This restriction is unnecessary for types which are already `Sync`.
---
## Changelog
+ Added the method `read` to `SyncCell`, which allows shared access to values that already implement the `Sync` trait.
# Objective
Web builds do not support running on multiple threads right now. Defaulting to the multi-threaded executor has significant overhead without any benefit.
## Solution
Default to the single threaded executor on wasm32 builds.
# Objective
- other tools (bevy_mod_debugdump) would like to have access to the ambiguities so that they can do their own reporting/visualization
## Solution
- store `conflicting_systems` in `ScheduleGraph` after calling `build_schedule`
The solution isn't very pretty and as pointed out it https://github.com/bevyengine/bevy/pull/7522, there may be a better way of exposing this, but this is the quick and dirty way if we want to have this functionality exposed in 0.10.
# Objective
- RemovedComponents is just a thin wrapper around Events/ManualEventReader which is the same as an EventReader, so most usecases that of an EventReader will probably be useful for RemovedComponents too.
I was thinking of making a trait for this but I don't think it is worth the overhead currently.
## Solution
- Mirror the api surface of EventReader
# Objective
Motivated by #7469.
`EventReader` iterators use the default implementations for `.nth()` and `.last()`, which includes iterating over and throwing out all events before the desired one.
## Solution
Add specialized implementations for these methods that directly updates the unread event counter and returns a reference to the desired event.
TODO:
- [x] Add a unit test.
- [x] ~~Add a benchmark, to see if the compiler was doing this automatically already.~~ *On second thought, this doesn't feel like a very useful thing to include in the benchmark suite.*
# Objective
- it would be nice to be able to associate a `NodeId` of a system type set to the `NodeId` of the actual system (used in bevy_mod_debugdump)
## Solution
- make `system_type` return the type id of the system
- that way you can check if a `dyn SystemSet` is the system type set of a `dyn System`
- I don't know if this information is already present somewhere else in the scheduler or if there is a better way to expose it
# Objective
Fixes#7702.
## Solution
- Added an test that ensures that no error is returned if a system or set is inside two different sets that share the same base set.
- Added an check to only return an error if the two base sets are not equal.
# Objective
The `ScheduleGraph` should be expose so that crates like [bevy_mod_debugdump](https://github.com/jakobhellermann/bevy_mod_debugdump/blob/stageless/docs/README.md) can access useful information.
## Solution
- expose `ScheduleGraph`, `NodeId`, `BaseSetMembership`, `Dag`
- add accessor functions for sets and systems
## Changelog
- expose `ScheduleGraph` for use in third party tools
This does expose our use of `petgraph` as a graph library, so we can only change that as a breaking change.
# Objective
- Fixes#5432
- Fixes#6680
## Solution
- move code responsible for generating the `impl TypeUuid` from `type_uuid_derive` into a new function, `gen_impl_type_uuid`.
- this allows the new proc macro, `impl_type_uuid`, to call the code for generation.
- added struct `TypeUuidDef` and implemented `syn::Parse` to allow parsing of the input for the new macro.
- finally, used the new macro `impl_type_uuid` to implement `TypeUuid` for the standard library (in `crates/bevy_reflect/src/type_uuid_impl.rs`).
- fixes#6680 by doing a wrapping add of the param's index to its `TYPE_UUID`

# Objective
The trait `Condition<>` is implemented for any type that can be converted into a `ReadOnlySystem` which takes no inputs and returns a bool. However, due to the current implementation, consumers of the trait cannot rely on the fact that `<T as Condition>::System` implements `ReadOnlySystem`. In cases such as the `not` combinator (added in #7559), we are required to add redundant `T::System: ReadOnlySystem` trait bounds, even though this should be implied by the `Condition<>` trait.
## Solution
Add a hidden associated type which allows the compiler to figure out that the `System` associated type implements `ReadOnlySystem`.
…able like Table. Rename clear to clear_entities to clarify that metadata keeps, only value cleared
# Objective
- Provide some inspectability for SparseSets.
## Solution
- `Tables` has these three methods, len, is_empty and iter too. Add these methods to `SparseSets`, so user can print the shape of storage.

- Add `len`, `is_empty`, `iter` methods on SparseSets.
- Rename `clear` to `clear_entities` to clarify its purpose.
- Add `new_for_test` on `ComponentInfo` to make test code easy.
- Add test case covering new methods.
## Migration Guide
> This section is optional. If there are no breaking changes, you can delete this section.
- Simply adding new functionality is not a breaking change.
# Objective
This PR improves message that caused by duplicate components in bundle.
## Solution
Show names of duplicate components.
The solution is not very elegant, in my opinion, I will be happy to listen to suggestions for improving it

# Objective
While porting my crate `bevy_trait_query` to bevy 0.10, I ran into an issue with the `DetectChangesMut` trait. Due to the way that the `set_if_neq` method (added in #6853) is implemented, you are forced to write a nonsense implementation of it for dynamically sized types. This edge case shows up when implementing trait queries, since `DetectChangesMut` is implemented for `Mut<dyn Trait>`.
## Solution
Simplify the generics for `set_if_neq` and add the `where Self::Target: Sized` trait bound to it. Add a default implementation so implementers don't need to implement a method with nonsensical trait bounds.
# Objective
The `SystemParamFunction` (and `ExclusiveSystemParamFunction`) trait is very cumbersome to use, due to it requiring four generic type parameters. These are currently all used as marker parameters to satisfy rust's trait coherence rules.
### Example (before)
```rust
pub fn pipe<AIn, Shared, BOut, A, AParam, AMarker, B, BParam, BMarker>(
mut system_a: A,
mut system_b: B,
) -> impl FnMut(In<AIn>, ParamSet<(AParam, BParam)>) -> BOut
where
A: SystemParamFunction<AIn, Shared, AParam, AMarker>,
B: SystemParamFunction<Shared, BOut, BParam, BMarker>,
AParam: SystemParam,
BParam: SystemParam,
```
## Solution
Turn the `In`, `Out`, and `Param` generics into associated types. Merge the marker types together to retain coherence.
### Example (after)
```rust
pub fn pipe<A, B, AMarker, BMarker>(
mut system_a: A,
mut system_b: B,
) -> impl FnMut(In<A::In>, ParamSet<(A::Param, B::Param)>) -> B::Out
where
A: SystemParamFunction<AMarker>,
B: SystemParamFunction<BMarker, In = A::Out>,
```
---
## Changelog
+ Simplified the `SystemParamFunction` and `ExclusiveSystemParamFunction` traits.
## Migration Guide
For users of the `SystemParamFunction` trait, the generic type parameters `In`, `Out`, and `Param` have been turned into associated types. The same has been done with the `ExclusiveSystemParamFunction` trait.
# Objective
The current doc comment for `flex-basis` states that it is "The initial size of the item", which is a bit confusing since size in Bevy is mostly used to refer to two-dimensional extents but `flex-basis` is a one-dimensional value.
It also needs to explain that:
* `flex-basis` sets the initial length of the main axis.
* Overrides `size` on the main axis.
* Obeys the `min_size` and `max_size` constraints.
# Objective
- #6402 changed `World::fetch_table` (now `UnsafeWorldCell::fetch_table`) to access the archetype in order to get the `table_id` and `table_row` of the entity involved. However this is useless since those were already present in the `EntityLocation`
- Moreover it's useless for `UnsafeWorldCell::fetch_table` to return the `TableRow` too, since the caller must already have access to the `EntityLocation` which contains the `TableRow`.
- The result is that `UnsafeWorldCell::fetch_table` now only does 2 memory fetches instead of 4.
## Solution
- Revert the changes to the implementation of `UnsafeWorldCell::fetch_table` made in #6402
…u64, so hash safety is not a concern
# Objective
- While reading the code, just noticed the BundleInfo's HashMap is std::collections::HashMap, which uses a slow but safe hasher.
## Solution
- Use bevy_utils::HashMap instead

## Changelog
> This section is optional. If this was a trivial fix, or has no externally-visible impact, you can delete this section.
- use bevy_utils::HashMap for Bundles::bundle_ids
## Migration Guide
> This section is optional. If there are no breaking changes, you can delete this section.
- Not a breaking change, hashmap is internal impl.
# Objective
We have a few old system labels that are now system sets but are still named or documented as labels. Documentation also generally mentioned system labels in some places.
## Solution
- Clean up naming and documentation regarding system sets
## Migration Guide
`PrepareAssetLabel` is now called `PrepareAssetSet`
# Objective
- Improve readability of the run condition for systems only running in a certain state
## Solution
- Rename `state_equals` to `in_state` (see [comment by cart](https://github.com/bevyengine/bevy/pull/7634#issuecomment-1428740311) in #7634 )
- `.run_if(state_equals(variant))` now is `.run_if(in_state(variant))`
This breaks the naming pattern a bit with the related conditions `state_exists` and `state_exists_and_equals` but I could not think of better names for those and think the improved readability of `in_state` is worth it.
# Objective
- Fixes#7612
- Since #7493, windows started as unfocused
## Solution
- Creating the window at the end of the event loop after the resume event instead of at the beginning of the loop of the next event fixes the focus
