# Objective
- In 0.14, ZIndex and GlobalZIndex where split from a shared enum into
separate components. There have been a few people confused by the
behavior of ZIndex when they really needed GlobalZIndex.
## Solution
- Update ZIndex docs to improve discoverability of GlobalZIndex.

# Objective
Fixes#16531
I also added change detection when creating the pipeline, which
technically isn't needed but it felt weird leaving it as is.
## Solution
Remove the pipeline if CAS is disabled. The uniform was already being
removed, which caused flickering / weirdness.
## Testing
Tested the anti_alias example by toggling CAS a bunch on/off.
# Objective
Animating component fields requires too much boilerplate at the moment:
```rust
#[derive(Reflect)]
struct FontSizeProperty;
impl AnimatableProperty for FontSizeProperty {
type Component = TextFont;
type Property = f32;
fn get_mut(component: &mut Self::Component) -> Option<&mut Self::Property> {
Some(&mut component.font_size)
}
}
animation_clip.add_curve_to_target(
animation_target_id,
AnimatableKeyframeCurve::new(
[0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0]
.into_iter()
.zip([24.0, 80.0, 24.0, 80.0, 24.0, 80.0, 24.0]),
)
.map(AnimatableCurve::<FontSizeProperty, _>::from_curve)
.expect("should be able to build translation curve because we pass in valid samples"),
);
```
## Solution
This adds `AnimatedField` and an `animated_field!` macro, enabling the
following:
```rust
animation_clip.add_curve_to_target(
animation_target_id,
AnimatableCurve::new(
animated_field!(TextFont::font_size),
AnimatableKeyframeCurve::new(
[0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0]
.into_iter()
.zip([24.0, 80.0, 24.0, 80.0, 24.0, 80.0, 24.0]),
)
.expect(
"should be able to build translation curve because we pass in valid samples",
),
),
);
```
This required reworking the internals a bit, namely stripping out a lot
of the `Reflect` usage, as that implementation was fundamentally
incompatible with the `AnimatedField` pattern. `Reflect` was being used
in this context just to downcast traits. But we can get downcasting
behavior without the `Reflect` requirement by implementing `Downcast`
for `AnimationCurveEvaluator`.
This also reworks "evaluator identity" to support either a (Component /
Field) pair, or a TypeId. This allows properties to reuse evaluators,
even if they have different accessor methods. The "contract" here is
that for a given (Component / Field) pair, the accessor will return the
same value. Fields are identified by their Reflect-ed field index. The
(TypeId, usize) is prehashed and cached to optimize for lookup speed.
This removes the built-in hard-coded TranslationCurve / RotationCurve /
ScaleCurve in favor of AnimatableField.

# Objective
The documentation for `bevy_app::App.world()` (and its mut variant)
could confuse some into thinking that this is the only World that the
App will contain.
## Solution
Clarify the documentation for `bevy_app::App.world()` (and its mut
variant), to say that it returns the main subapp's world. This helps
imply that Apps can contain more than one world (albeit, only one per
SubApp).
## Testing
This is a documentation change, with no changes to doctests. Thus,
testing is not necessary beyond ensuring the link syntax is correct.
# Objective
Fixes#16521
## Solution
If an empty span is encountered (such as the default `Text` value), we
skip it entirely when updating buffers. This prevents unnecessarily
bailing when the font doesn't exist (ex: when the default font is
disabled)
This reverts commit 3476a9f3a658fe7c8326ca0e618ad543914ca7f4.
# Objective
#16517 makes it impossible to select a libc version, now that the
"breaking" libc release was yanked
## Solution
Revert the version bump so we can select a version of sysinfo that
builds (the previous version)
# Objective
- Fixes#16363
- Ensure that someone using minimum version doesn't get the bugs that
were fixed in the 23.0.1 patch
## Solution
- Use wgpu 23.0.1
# Objective
In the [*Similar parameters* section of
`Query`](https://dev-docs.bevyengine.org/bevy/ecs/prelude/struct.Query.html#similar-parameters),
the doc link for `Single` actually links to `Query::single`, and
`Option<Single>` just links to `Option`. They should both link to
`Single`!
The first link is broken because there is a reference-style link defined
for `single`, but not for `Single`, and rustdoc treats the link as
case-insensitive for some reason.
## Solution
Fix the links!
## Testing
I built the docs locally with `cargo doc` and tested the links.
# Objective
- Refactor
## Solution

## Migration Guide
`RenderCreation::Manual` variant fields are now wrapped in a struct
called `RenderResources`
# Objective
`TemporaryRenderEntity` currently uses `SparseSet` storage, but doesn't
seem to fit the criteria for a component that would benefit from this.
Typical usage of `TemporaryRenderEntity` (and all current usages of it
in engine as far as I can tell) would be to spawn an entity with it once
and then iterate over it once to despawn that entity.
`SparseSet` is said to be useful for insert/removal perf at the cost of
iteration perf.
## Solution
Use the default table storage
## Testing
Possibly this could show up in stress tests like `many_buttons`. I
didn't do any benchmarking.
# Objective
When using a rect for a ui image, its content size is still equal to the
size of the full image instead of the size of the rect.
## Solution
Use the rect size if it is present.
## Testing
I tested it using all 4 possible combinations of having a rect and
texture atlas or not. See the showcase section.

# Objective
Original motivation was a bundle I am migrating that is `Copy` which
needs to be synced to the render world. It probably doesn't actually
*need* to be `Copy`, so this isn't critical or anything.
I am continuing to use this bundle while bundles still exist to give
users an easier migration path.
## Solution
These ZSTs might as well be `Copy`. Add `Copy` derives.
PR #15164 made Bevy consider the center of the mesh to be the center of
the axis-aligned bounding box (AABB). Unfortunately, this breaks
crossfading in many cases. LODs may have different AABBs and so the
center of the AABB may differ for different LODs of the same mesh. The
crossfading, however, relies on all LODs having *precisely* the same
position.
To address this problem, this PR adds a new field, `use_aabb`, to
`VisibilityRange`, which makes the AABB center point behavior opt-in.
@BenjaminBrienen first noticed this issue when reviewing PR #16286. That
PR contains a video showing the effects of this regression on the
`visibility_range` example. This commit fixes that example.
## Migration Guide
* The `VisibilityRange` component now has an extra field, `use_aabb`.
Generally, you can safely set it to false.
We have an early-out to avoid updating `RenderVisibilityRanges` when a
`VisibilityRange` component is *modified*, but not when one is
*removed*. This means that removing `VisibilityRange` from an entity
might not update the rendering.
This PR fixes the issue by adding a check for removed
`VisibilityRange`s.
# Objective
- Fixes#16472.
## Solution
- Add flags to `SpritePlugin` and `UiPlugin` to disable their picking
backends.
## Testing
- The change is pretty trivial, so not much to test!
---
## Migration Guide
- `UiPlugin` now contains an extra `add_picking` field if
`bevy_ui_picking_backend` is enabled.
- `SpritePlugin` is no longer a unit struct, and has one field if
`bevy_sprite_picking_backend` is enabled (otherwise no fields).
# Objective
- Fixes#16469.
## Solution
- Make the picking backend features not enabled by default in each
sub-crate.
- Make features in `bevy_internal` to set the backend features
- Make the root `bevy` crate set the features by default.
## Testing
- The mesh and sprite picking examples still work correctly.
I'm not sure why, but somehow `#[derive(Reflect)]` on a tuple struct
with a boxed trait object can result in linker errors when dynamic
linking is used on Windows using `rust-lld`:
```

```
etc.
Adding `#[reflect(opaque)]` to the `Reflect` derive fixes the problem,
and that's what this patch does. I think that adding
`#[reflect(opaque)]` is harmless, as there's little that reflection
allows with a boxed trait object anyhow.
# Objective
- Fixes#16406 even more. The previous implementation did not take into
account the depth of the requiree when setting the depth relative to the
required_by component.
## Solution
- Add the depth of the requiree!
## Testing
- Added a test.

# Objective
We switch back and forwards between logical and physical coordinates all
over the place. Systems have to query for cameras and the UiScale when
they shouldn't need to. It's confusing and fragile and new scale factor
bugs get found constantly.
## Solution
* Use physical coordinates whereever possible in `bevy_ui`.
* Store physical coords in `ComputedNode` and tear out all the unneeded
scale factor calculations and queries.
* Add an `inverse_scale_factor` field to `ComputedNode` and set nodes
changed when their scale factor changes.
## Migration Guide
`ComputedNode`'s fields and methods now use physical coordinates.
`ComputedNode` has a new field `inverse_scale_factor`. Multiplying the
physical coordinates by the `inverse_scale_factor` will give the logical
values.

# Objective
Needing to derive `AnimationEvent` for `Event` is unnecessary, and the
trigger logic coupled to it feels like we're coupling "event producer"
logic with the event itself, which feels wrong. It also comes with a
bunch of complexity, which is again unnecessary. We can have the
flexibility of "custom animation event trigger logic" without this
coupling and complexity.
The current `animation_events` example is also needlessly complicated,
due to it needing to work around system ordering issues. The docs
describing it are also slightly wrong. We can make this all a non-issue
by solving the underlying ordering problem.
Related to this, we use the `bevy_animation::Animation` system set to
solve PostUpdate animation order-of-operations issues. If we move this
to bevy_app as part of our "core schedule", we can cut out needless
`bevy_animation` crate dependencies in these instances.
## Solution
- Remove `AnimationEvent`, the derive, and all other infrastructure
associated with it (such as the `bevy_animation/derive` crate)
- Replace all instances of `AnimationEvent` traits with `Event + Clone`
- Store and use functions for custom animation trigger logic (ex:
`clip.add_event_fn()`). For "normal" cases users dont need to think
about this and should use the simpler `clip.add_event()`
- Run the `Animation` system set _before_ updating text
- Move `bevy_animation::Animation` to `bevy_app::Animation`. Remove
unnecessary `bevy_animation` dependency from `bevy_ui`
- Adjust `animation_events` example to use the simpler `clip.add_event`
API, as the workarounds are no longer necessary
This is polishing work that will land in 0.15, and I think it is simple
enough and valuable enough to land in 0.15 with it, in the interest of
making the feature as compelling as possible.
# Objective
A new user is likely to try `Query<Component>` instead of
`Query<&Component>`. The error message should guide them to the right
solution.
## Solution
Add a note to the on_unimplemented message for `QueryData` recommending
`&T` and `&mut T`.
The full error message now looks like:
```

Alternative to #16450
# Objective
detailed_trace! in its current form does not work (and breaks CI)
## Solution
Fix detailed_trace by checking for the feature properly, adding it to
the correct crates, and removing it from the incorrect crates
# Objective
- Fixes#16406
- Fixes an issue where registering a "deeper" required component, then a
"shallower" required component, would result in the wrong required
constructor being used for the root component.
## Solution
- Make `register_required_components` add any "parent" of a component as
`required_by` to the new "child".
- Assign the depth of the `requiree` plus 1 as the depth of a new
runtime required component.
## Testing
- Added two new tests.
# Objective
- Add methods to facilitate `TextFont` component creation and insertion.
## Solution
- Added `from_font` and `from_font_size` which return a new `TextFont`
with said attributes provided as parameters.
- Added `with_font` and `with_font_size` which return an existing
`TextFont` modifying said attributes with the values provided as
parameters.
## Testing
- CI Checks.
- Tested methods locally by changing values and running the `text_debug`
example.
# Objective
Run this without this PR:
`cargo build -p bevy_hierarchy --no-default-features`
You'll get:
```

#[cfg_attr(feature = "reflect", derive(Reflect), reflect(Debug, PartialEq))]

## Testing

# Objective
It looks like this file was created based on the `ui_texture_slice`
rendering code and some variable names weren't updated.
## Solution
Rename "texture slice" variable names to "box shadow".
# Objective
#16222 regressed the user experience of actually using gamepads:
```rust
// Before 16222
gamepad.just_pressed(GamepadButton::South)
// After 16222
gamepad.digital.just_pressed(GamepadButton::South)
// Before 16222
gamepad.get(GamepadButton::RightTrigger2)
// After 16222
gamepad.analog.get(GamepadButton::RighTrigger2)
```
Users shouldn't need to think about "digital vs analog" when checking if
a button is pressed. This abstraction was intentional and I strongly
believe it is in our users' best interest. Buttons and Axes are _both_
digital and analog, and this is largely an implementation detail. I
don't think reverting this will be controversial.
## Solution
- Revert most of #16222
- Add the `Into<T>` from #16222 to the internals
- Expose read/write `digital` and `analog` accessors on gamepad, in the
interest of enabling the mocking scenarios covered in #16222 (and
allowing the minority of users that care about the "digital" vs "analog"
distinction in this context to make that distinction)

# Objective
- bevy_render (poorly) implements gcd (which should be in bevy_math but
theres not enough justification to have it there either anyways cus its
just one usage)
## Solution
- hardcoded LUT replacement for the one usage
## Testing
- verified the alternative implementation of 4/gcd(4,x) agreed with
original for 0..200
# Objective
https://github.com/AccessKit/accesskit/pull/475 changed how text content
should be set for AccessKit nodes with a role of `Label`. This was
unfortunately missing from #16234.
## Solution
When building an `accesskit::Node` with `Role::Label`, calls `set_value`
instead of `set_label` on the node to set its content.
## Testing
I can't test this right now on my Windows machine due to a compilation
error with wgpu-hal I have no idea how to resolve.
**NOTE: This is based on, and should be merged alongside,
https://github.com/bevyengine/bevy/pull/15482.** I'll leave this in
draft until that PR is merged.
# Objective
Equivalent of https://github.com/bevyengine/bevy/pull/15482 but for
serialization. See that issue for the motivation.
Also part of this tracking issue:
https://github.com/bevyengine/bevy/issues/15518
This PR is non-breaking, just like the deserializer PR (because the new
type parameter `P` has a default `P = ()`).
## Solution
Identical solution to the deserializer PR.
## Testing
Added unit tests and a very comprehensive doc test outlining a clear
example and use case.
# Objective
Fixes#16406.
Currently, the `#[require(...)]` attribute internally registers
component requirements using `register_required_components_manual`. This
is done recursively in a way where every requirement in the "inheritance
tree" is added into a flat `RequiredComponents` hash map with component
constructors and inheritance depths stored.
However, this does not consider runtime requirements: if a plugins has
already registered `C` as required by `B`, and a component `A` requires
`B` through the macro attribute, spawning an entity with `A` won't add
`C`. The `required_by` hash set for `C` doesn't have `A`, and the
`RequiredComponents` of `A` don't have `C`.
Intuitively, I would've thought that the macro attribute's requirements
were always added *before* runtime requirements, and in that case I
believe this shouldn't have been an issue. But the macro requirements
are based on `Component::register_required_components`, which in a lot
of cases (I think) is only called *after* the first time a bundle with
the component is inserted. So if a runtime requirement is defined
*before* this (as is often the case, during `Plugin::build`), the macro
may not take it into account.
## Solution
Register requirements inherited from the `required` component in
`register_required_components_manual_unchecked`.
## Testing
I added a test, essentially the same as in #16406, and it now passes. I
also ran some of the tests in #16409, and they seem to work as expected.
All the existing tests for required components pass.
# Objective
Seemed to have missed the export of `DynamicComponentFetch` from #15593.
`TryFromFilteredError` which is returned by `impl
TryFrom<FiliteredEntityMut/Ref> for EntityRef/Mut` also seemed to have
been missing.
## Solution
Export both of them.
# Objective
MSRV in the standalone crates should be accurate
## Solution
Determine the msrv of each crate and set it
## Testing
Adding better msrv checks to the CI is a next-step.
# Objective
- Fix part of #15920
## Solution
- Keep track of the last written amount of bytes, and bind only that
much of the buffer.
## Testing
- Did you test these changes? If so, how? No
- Are there any parts that need more testing?
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?

## Migration Guide
- Fixed a bug with StorageBuffer and DynamicStorageBuffer binding data
from the previous frame(s) due to caching GPU buffers between frames.
# Objective
When adding custom BRP methods one might need to:
- Run custom systems in the `RemoteLast` schedule.
- Order those systems before/after request processing and cleanup.
For example in `bevy_remote_inspector` we need a way to perform some
preparation _before_ request processing. And to perform cleanup
_between_ request processing and watcher cleanup.
## Solution
- Make `RemoteLast` public
- Add `RemoteSet` with `ProcessRequests` and `Cleanup` variants.
I didn't mean to make this item private, fixing it for the 0.15 release
to be consistent with 0.14.
(maintainers: please make sure this gets merged into the 0.15 release
branch as well as main)
# Objective
- Fixes#16152
## Solution
- Put `bevy_window` and `bevy_a11y` behind the `bevy_window` feature.
they were the only difference
- Add `ScheduleRunnerPlugin` to the `DefaultPlugins` when `bevy_window`
is disabled
- Remove `HeadlessPlugins`
- Update the `headless` example
# Objective
- Fixes#16285
- Inactive camera are keeping the component `ViewUniformOffset` from
when they were active, still matching some queries trying to render to
them
## Solution
- Remove component `ViewUniformOffset` from cameras that are inactive
## Testing
- Ran example `render_primitives` and switched camera
