# Objective
- Progress towards #19887.
## Solution
- Rewrite the FromWorld impls to systems that create the pipeline
resources.
## Testing
- Ran the `anti_aliasing` example and it still works.
A few versions ago, wgpu made it possible to set shader entry point to
`None`, which will select the correct entry point in file where only a
single entrypoint is specified. This makes it possible to implement
`Default` for pipeline descriptors. This PR does so and attempts to
`..default()` everything possible.
# Objective
- This unblocks some work I am doing for #19887.
## Solution
- Rename `RenderGraphApp` to `RenderGraphExt`.
- Implement `RenderGraphExt` for `World`.
- Change `SubApp` and `App` to call the `World` impl.
# Objective
- Progress towards #19024.
## Solution
- Remove `Handle::Weak`!
If users were relying on `Handle::Weak` for some purpose, they can
almost certainly replace it with raw `AssetId` instead. If they cannot,
they can make their own enum that holds either a Handle or an AssetId.
In either case, we don't need weak handles!
Sadly we still need Uuid handles since we rely on them for "default"
assets and "invalid" assets, as well as anywhere where a component wants
to impl default with a non-defaulted asset handle. One step at a time
though!
# Objective
- Related to #19024.
## Solution
- Remove the `FULLSCREEN_SHADER_HANDLE` `weak_handle` with a resource
holding the shader handle.
- This also changes us from using `load_internal_asset` to
`embedded_asset`/`load_embedded_asset`.
- All uses have been migrated to clone the `FullscreenShader` resource
and use its `to_vertex_state` method.
## Testing
- `anti_aliasing` example still works.
- `bloom_3d` example still works.

# Objective
Improve the performance of `FilteredEntity(Ref|Mut)` and
`Entity(Ref|Mut)Except`.
`FilteredEntityRef` needs an `Access<ComponentId>` to determine what
components it can access. There is one stored in the query state, but
query items cannot borrow from the state, so it has to `clone()` the
access for each row. Cloning the access involves memory allocations and
can be expensive.
## Solution
Let query items borrow from their query state.
Add an `'s` lifetime to `WorldQuery::Item` and `WorldQuery::Fetch`,
similar to the one in `SystemParam`, and provide `&'s Self::State` to
the fetch so that it can borrow from the state.
Unfortunately, there are a few cases where we currently return query
items from temporary query states: the sorted iteration methods create a
temporary state to query the sort keys, and the
`EntityRef::components<Q>()` methods create a temporary state for their
query.
To allow these to continue to work with most `QueryData`
implementations, introduce a new subtrait `ReleaseStateQueryData` that
converts a `QueryItem<'w, 's>` to `QueryItem<'w, 'static>`, and is
implemented for everything except `FilteredEntity(Ref|Mut)` and
`Entity(Ref|Mut)Except`.
`#[derive(QueryData)]` will generate `ReleaseStateQueryData`
implementations that apply when all of the subqueries implement
`ReleaseStateQueryData`.
This PR does not actually change the implementation of
`FilteredEntity(Ref|Mut)` or `Entity(Ref|Mut)Except`! That will be done
as a follow-up PR so that the changes are easier to review. I have
pushed the changes as chescock/bevy#5.
## Testing
I ran performance traces of many_foxes, both against main and against
chescock/bevy#5, both including #15282. These changes do appear to make
generalized animation a bit faster:
(Red is main, yellow is chescock/bevy#5)
## Migration Guide
The `WorldQuery::Item` and `WorldQuery::Fetch` associated types and the
`QueryItem` and `ROQueryItem` type aliases now have an additional
lifetime parameter corresponding to the `'s` lifetime in `Query`. Manual
implementations of `WorldQuery` will need to update the method
signatures to include the new lifetimes. Other uses of the types will
need to be updated to include a lifetime parameter, although it can
usually be passed as `'_`. In particular, `ROQueryItem` is used when
implementing `RenderCommand`.
Before:
```rust
fn render<'w>(
item: &P,
view: ROQueryItem<'w, Self::ViewQuery>,
entity: Option<ROQueryItem<'w, Self::ItemQuery>>,
param: SystemParamItem<'w, '_, Self::Param>,
pass: &mut TrackedRenderPass<'w>,
) -> RenderCommandResult;
```
After:
```rust
fn render<'w>(
item: &P,
view: ROQueryItem<'w, '_, Self::ViewQuery>,
entity: Option<ROQueryItem<'w, '_, Self::ItemQuery>>,
param: SystemParamItem<'w, '_, Self::Param>,
pass: &mut TrackedRenderPass<'w>,
) -> RenderCommandResult;
```
---
Methods on `QueryState` that take `&mut self` may now result in
conflicting borrows if the query items capture the lifetime of the
mutable reference. This affects `get()`, `iter()`, and others. To fix
the errors, first call `QueryState::update_archetypes()`, and then
replace a call `state.foo(world, param)` with
`state.query_manual(world).foo_inner(param)`. Alternately, you may be
able to restructure the code to call `state.query(world)` once and then
make multiple calls using the `Query`.
Before:
```rust
let mut state: QueryState<_, _> = ...;
let d1 = state.get(world, e1);
let d2 = state.get(world, e2); // Error: cannot borrow `state` as mutable more than once at a time
println!("{d1:?}");
println!("{d2:?}");
```
After:
```rust
let mut state: QueryState<_, _> = ...;
state.update_archetypes(world);
let d1 = state.get_manual(world, e1);
let d2 = state.get_manual(world, e2);
// OR
state.update_archetypes(world);
let d1 = state.query(world).get_inner(e1);
let d2 = state.query(world).get_inner(e2);
// OR
let query = state.query(world);
let d1 = query.get_inner(e1);
let d1 = query.get_inner(e2);
println!("{d1:?}");
println!("{d2:?}");
```
The first 4 commits are designed to be reviewed independently.
- Mark TAA non-experimental now that motion vectors are written for
skinned and morphed meshes, along with skyboxes, and add it to
DefaultPlugins
- Adjust halton sequence to match what DLSS is going to use, doesn't
really affect anything, but may as well
- Make MipBias a required component on TAA instead of inserting it in
the render world
- Remove MipBias, TemporalJitter, RenderLayers, etc from the render
world if they're removed from the main world (fixes a retained render
world bug)
- Remove TAA components from the render world properly if
TemporalAntiAliasing is removed from the main world (fixes a retained
render world bug)
- extract_taa_settings() now has to query over `Option<&mut
TemporalAntiAliasing>`, which will match every single camera, in order
to cover cameras that had TemporalAntiAliasing removed this frame. This
kind of sucks, but I can't think of anything better.
- We probably have the same bug with every other rendering feature
component we have.

# Objective
- Related to #19024
## Solution
- Use the new `load_shader_library` macro for the shader libraries and
`embedded_asset`/`load_embedded_asset` for the "shader binaries" in
`bevy_anti_aliasing`.
## Testing
- `anti_aliasing` example still works.
P.S. I don't think this needs a migration guide. Technically users could
be using the `pub` weak handles, but there's no actual good use for
them, so omitting it seems fine. Alternatively, we could mix this in
with the migration guide notes for #19137.
# Objective
Fixes a part of #14274.
Bevy has an incredibly inconsistent naming convention for its system
sets, both internally and across the ecosystem.
<img alt="System sets in Bevy"

width="450" />
*Names of public system set types in Bevy*
Most Bevy types use a naming of `FooSystem` or just `Foo`, but there are
also a few `FooSystems` and `FooSet` types. In ecosystem crates on the
other hand, `FooSet` is perhaps the most commonly used name in general.
Conventions being so wildly inconsistent can make it harder for users to
pick names for their own types, to search for system sets on docs.rs, or
to even discern which types *are* system sets.
To reign in the inconsistency a bit and help unify the ecosystem, it
would be good to establish a common recommended naming convention for
system sets in Bevy itself, similar to how plugins are commonly suffixed
with `Plugin` (ex: `TimePlugin`). By adopting a consistent naming
convention in first-party Bevy, we can softly nudge ecosystem crates to
follow suit (for types where it makes sense to do so).
Choosing a naming convention is also relevant now, as the [`bevy_cli`
recently adopted
lints](https://github.com/TheBevyFlock/bevy_cli/pull/345) to enforce
naming for plugins and system sets, and the recommended naming used for
system sets is still a bit open.
## Which Name To Use?
Now the contentious part: what naming convention should we actually
adopt?
This was discussed on the Bevy Discord at the end of last year, starting
[here](<https://discord.com/channels/691052431525675048/692572690833473578/1310659954683936789>).
`FooSet` and `FooSystems` were the clear favorites, with `FooSet` very
narrowly winning an unofficial poll. However, it seems to me like the
consensus was broadly moving towards `FooSystems` at the end and after
the poll, with Cart
([source](https://discord.com/channels/691052431525675048/692572690833473578/1311140204974706708))
and later Alice
([source](https://discord.com/channels/691052431525675048/692572690833473578/1311092530732859533))
and also me being in favor of it.
Let's do a quick pros and cons list! Of course these are just what I
thought of, so take it with a grain of salt.
`FooSet`:
- Pro: Nice and short!
- Pro: Used by many ecosystem crates.
- Pro: The `Set` suffix comes directly from the trait name `SystemSet`.
- Pro: Pairs nicely with existing APIs like `in_set` and
`configure_sets`.
- Con: `Set` by itself doesn't actually indicate that it's related to
systems *at all*, apart from the implemented trait. A set of what?
- Con: Is `FooSet` a set of `Foo`s or a system set related to `Foo`? Ex:
`ContactSet`, `MeshSet`, `EnemySet`...
`FooSystems`:
- Pro: Very clearly indicates that the type represents a collection of
systems. The actual core concept, system(s), is in the name.
- Pro: Parallels nicely with `FooPlugins` for plugin groups.
- Pro: Low risk of conflicts with other names or misunderstandings about
what the type is.
- Pro: In most cases, reads *very* nicely and clearly. Ex:
`PhysicsSystems` and `AnimationSystems` as opposed to `PhysicsSet` and
`AnimationSet`.
- Pro: Easy to search for on docs.rs.
- Con: Usually results in longer names.
- Con: Not yet as widely used.
Really the big problem with `FooSet` is that it doesn't actually
describe what it is. It describes what *kind of thing* it is (a set of
something), but not *what it is a set of*, unless you know the type or
check its docs or implemented traits. `FooSystems` on the other hand is
much more self-descriptive in this regard, at the cost of being a bit
longer to type.
Ultimately, in some ways it comes down to preference and how you think
of system sets. Personally, I was originally in favor of `FooSet`, but
have been increasingly on the side of `FooSystems`, especially after
seeing what the new names would actually look like in Avian and now
Bevy. I prefer it because it usually reads better, is much more clearly
related to groups of systems than `FooSet`, and overall *feels* more
correct and natural to me in the long term.
For these reasons, and because Alice and Cart also seemed to share a
preference for it when it was previously being discussed, I propose that
we adopt a `FooSystems` naming convention where applicable.
## Solution
Rename Bevy's system set types to use a consistent `FooSet` naming where
applicable.
- `AccessibilitySystem` → `AccessibilitySystems`
- `GizmoRenderSystem` → `GizmoRenderSystems`
- `PickSet` → `PickingSystems`
- `RunFixedMainLoopSystem` → `RunFixedMainLoopSystems`
- `TransformSystem` → `TransformSystems`
- `RemoteSet` → `RemoteSystems`
- `RenderSet` → `RenderSystems`
- `SpriteSystem` → `SpriteSystems`
- `StateTransitionSteps` → `StateTransitionSystems`
- `RenderUiSystem` → `RenderUiSystems`
- `UiSystem` → `UiSystems`
- `Animation` → `AnimationSystems`
- `AssetEvents` → `AssetEventSystems`
- `TrackAssets` → `AssetTrackingSystems`
- `UpdateGizmoMeshes` → `GizmoMeshSystems`
- `InputSystem` → `InputSystems`
- `InputFocusSet` → `InputFocusSystems`
- `ExtractMaterialsSet` → `MaterialExtractionSystems`
- `ExtractMeshesSet` → `MeshExtractionSystems`
- `RumbleSystem` → `RumbleSystems`
- `CameraUpdateSystem` → `CameraUpdateSystems`
- `ExtractAssetsSet` → `AssetExtractionSystems`
- `Update2dText` → `Text2dUpdateSystems`
- `TimeSystem` → `TimeSystems`
- `AudioPlaySet` → `AudioPlaybackSystems`
- `SendEvents` → `EventSenderSystems`
- `EventUpdates` → `EventUpdateSystems`
A lot of the names got slightly longer, but they are also a lot more
consistent, and in my opinion the majority of them read much better. For
a few of the names I took the liberty of rewording things a bit;
definitely open to any further naming improvements.
There are still also cases where the `FooSystems` naming doesn't really
make sense, and those I left alone. This primarily includes system sets
like `Interned<dyn SystemSet>`, `EnterSchedules<S>`, `ExitSchedules<S>`,
or `TransitionSchedules<S>`, where the type has some special purpose and
semantics.
## Todo
- [x] Should I keep all the old names as deprecated type aliases? I can
do this, but to avoid wasting work I'd prefer to first reach consensus
on whether these renames are even desired.
- [x] Migration guide
- [x] Release notes
# Objective
- Fixes https://github.com/bevyengine/bevy/issues/17891
- Cherry-picked from https://github.com/bevyengine/bevy/pull/18411
## Solution
The `name` argument could either be made permanent (by removing the
`#[cfg(...)]` condition) or eliminated entirely. I opted to remove it,
as debugging a specific DDS texture edge case in GLTF files doesn't seem
necessary, and there isn't any other foreseeable need to have it.
## Migration Guide
- `Image::from_buffer()` no longer has a `name` argument that's only
present in debug builds when the `"dds"` feature is enabled. If you
happen to pass a name, remove it.
# Objective
- Compile failure with `bevy_anti_aliasing` due to `dds` feature not
enabling `bevy_core_pipeline/dds`, causing a public API desync.
## Solution
- Ensured feature is enabled
## Testing
- CI
# Objective
- bevy_core_pipeline is getting really big and it's a big bottleneck for
compilation time. A lot of parts of it can be broken up
## Solution
- Add a new bevy_anti_aliasing crate that contains all the anti_aliasing
implementations
- I didn't move any MSAA related code to this new crate because that's a
lot more invasive
## Testing
- Tested the anti_aliasing example to make sure all methods still worked
---
## Showcase
before:
after:
Notice that now bevy_core_pipeline is 1s shorter and bevy_anti_aliasing
now compiles in parallel with bevy_pbr.
## Migration Guide
When using anti aliasing features, you now need to import them from
`bevy::anti_aliasing` instead of `bevy::core_pipeline`
