- Add serialize feature to bevy_color
- "Fixes #12527".
## Solution
- Added feature for serialization
---
## Changelog
- Serde serialization is now optional, with flag 'serialize'
## Migration Guide
- If user wants color data structures to be serializable, then
application needs to be build with flag 'serialize'

# Objective
We already collect a lot of system information on startup when possible
but we don't make this information available. With the upcoming work on
a diagnostic overlay it would be useful to be able to display this
information.
## Solution
Make the already existing SystemInfo a Resource
---
## Changelog
Added `SystemInfo` Resource

# Objective
get_asset_paths tries to check whether a folder is empty, and if so
delete it. However rather than checking whether any subfolder contains
files it checks whether _all_ subfolders have files.
Also cleanup various BoxedFutures in async recursive functions like
these, rust 1.77 now allows recursive async functions (albeit still by
boxing), hurray! This is a followup to #12550 (sorta). More BoxedFuture
stuff can be removed now that rust 1.77 is out, which can use async
recursive functions! This is mainly just cleaner code wise - the
recursion still boxes the future so not much to win there.
PR is mainly whitespace changes so do disable whitespace diffs for
easier review.
# Objective
Follow up from PR #12369 to extract lighting structs from light/mod.rs
into their own file.
Part of the Purdue Refactoring Team's goals issue #12349
## Solution
- Moved PointLight from light/mod.rs to light/point_light.rs
- Moved SpotLight from light/mod.rs to light/spot_light.rs
- Moved DirectionalLight from light/mod.rs to light/directional_light.rs
# Objective
Remove color specialization from `SpritePipeline` after it became
useless in #9597
## Solution
Removed the `COLORED` flag from the pipeline key and removed the
specializing the pipeline over it.
---
## Changelog
### Removed
- `SpritePipelineKey` no longer contains the `COLORED` flag. The flag
has had no effect on how the pipeline operates for a while.
## Migration Guide
- The raw values for the `HDR`, `TONEMAP_IN_SHADER` and `DEBAND_DITHER`
flags have changed, so if you were constructing the pipeline key from
raw `u32`s you'll have to account for that.
# Objective
I was reading some of the Archetype and Bundle code and was getting
confused a little bit in some places (is the `archetype_id` in
`AddBundle` the source or the target archetype id?).
Small PR that adds some docstrings to make it easier for first-time
readers.
# Objective
* Adopted #12025 to fix merge conflicts
* In some cases we used manual impls for certain types, though they are
(at least, now) unnecessary.
## Solution
* Use macros and reflecting-by-value to avoid this clutter.
* Though there were linker issues with Reflect and the CowArc in
AssetPath (see https://github.com/bevyengine/bevy/issues/9747), I
checked these are resolved by using #[reflect_value].

# Objective
- Clarify that `ButtonInput::just_release` and
`ButtonInput::just_pressed` don't imply information about the state of
`ButtonInput::pressed` or their counterparts.
Fixes#12600
## Solution
Removed Into<AssetId<T>> for Handle<T> as proposed in Issue
conversation, fixed dependent code
## Migration guide
If you use passing Handle by value as AssetId, you should pass reference
or call .id() method on it
Before (0.13):
`assets.insert(handle, value);`
After (0.14):
`assets.insert(&handle, value);`
or
`assets.insert(handle.id(), value);`
# Objective
- Implements maths and `Animatable` for `Srgba` as suggested
[here](https://github.com/bevyengine/bevy/issues/12617#issuecomment-2013494774).
## Solution
- Implements `Animatable` and maths for `Srgba` just like their
implemented for other colors.
---
## Changelog
- Updated the example to mention `Srgba`.
## Migration Guide
- The previously existing implementation of mul/div for `Srgba` did not
modify `alpha` but these operations do modify `alpha` now. Users need to
be aware of this change.
# Objective
- Allow registering of systems from Commands with
`Commands::register_one_shot_system`
- Make registering of one shot systems more easy
## Solution
- Add the Command `RegisterSystem` for Commands use.
- Creation of SystemId based on lazy insertion of the System
- Changed the privacy of the fields in SystemId so Commands can return
the SystemId
---
## Changelog
### Added
- Added command `RegisterSystem`
- Added function `Commands::register_one_shot_system`
- Added function `App::register_one_shot_system`
### Changed
- Changed the privacy and the type of struct tuple to regular struct of
SystemId
## Migration Guide
- Changed SystemId fields from tuple struct to a normal struct
If you want to access the entity field, you should use
`SystemId::entity` instead of `SystemId::0`
## Showcase
> Before, if you wanted to register a system with `Commands`, you would
need to do:
```rust
commands.add(|world: &mut World| {
let id = world.register_system(your_system);
// You would need to insert the SystemId inside an entity or similar
})
```
> Now, you can:
```rust
let id = commands.register_one_shot_system(your_system);
// Do what you want with the Id
```

# Objective
I'm reading through the ecs query code for the first time, and updating
the docs:
- fixed some typos
- added some docs about things I was confused about (in particular what
the difference between `matches_component_set` and
`update_component_access` was)
# Objective
Fixes#12200 .
## Solution
I added a Hue Trait with the rotate_hue method to enable hue rotation.
Additionally, I modified the implementation of animations in the
animated_material sample.
---
## Changelog
- Added a `Hue` trait to `bevy_color/src/color_ops.rs`.
- Added the `Hue` trait implementation to `Hsla`, `Hsva`, `Hwba`,
`Lcha`, and `Oklcha`.
- Updated animated_material sample.
## Migration Guide
Users of Oklcha need to change their usage to use the with_hue method
instead of the with_h method.

# Objective
- Fixes#12202
## Solution
- Implements `Animatable` for all color types implementing arithmetic
operations.
- the colors returned by `Animatable`s methods are already clamped.
- Adds a `color_animation.rs` example.
- Implements the `*Assign` operators for color types that already had
the corresponding operators. This is just a 'nice to have' and I am
happy to remove this if it's not wanted.

# Objective
- It can be useful to have access to the path of the current asset being
processed, for example if you want to need a second file that is
relative to the current file being processed.
## Solution
- I added a `path()` function to the `ProcessContext`
# Objective
- Fixes#12570
## Solution
Previously, cardinal splines constructed by `CubicCardinalSpline` would
leave out their endpoints when constructing the cubic curve segments
connecting their points. (See the linked issue for details.)
Now, cardinal splines include the endpoints. For instance, the provided
usage example
```rust
let points = [
vec2(-1.0, -20.0),
vec2(3.0, 2.0),
vec2(5.0, 3.0),
vec2(9.0, 8.0),
];
let cardinal = CubicCardinalSpline::new(0.3, points).to_curve();
let positions: Vec<_> = cardinal.iter_positions(100).collect();
```
will actually produce a spline that connects all four of these points
instead of just the middle two "interior" points.
Internally, this is achieved by duplicating the endpoints of the vector
of control points before performing the construction of the associated
`CubicCurve`. This amounts to specifying that the tangents at the
endpoints `P_0` and `P_n` (say) should be parallel to `P_1 - P_0` and
`P_n - P_{n-1}`.
---
## Migration Guide
Any users relying on the old behavior of `CubicCardinalSpline` will have
to truncate any parametrizations they used in order to access a curve
identical to the one they had previously. This would be done by chopping
off a unit-distance segment from each end of the parametrizing interval.
For instance, if a user's existing code looks as follows
```rust
fn interpolate(t: f32) -> Vec2 {
let points = [
vec2(-1.0, -20.0),
vec2(3.0, 2.0),
vec2(5.0, 3.0),
vec2(9.0, 8.0),
];
let my_curve = CubicCardinalSpline::new(0.3, points).to_curve();
my_curve.position(t)
}
```
then in order to obtain similar behavior, `t` will need to be shifted up
by 1, since the output of `CubicCardinalSpline::to_curve` has introduced
a new segment in the interval [0,1], displacing the old segment from
[0,1] to [1,2]:
```rust
fn interpolate(t: f32) -> Vec2 {
let points = [
vec2(-1.0, -20.0),
vec2(3.0, 2.0),
vec2(5.0, 3.0),
vec2(9.0, 8.0),
];
let my_curve = CubicCardinalSpline::new(0.3, points).to_curve();
my_curve.position(t+1)
}
```
(Note that this does not provide identical output for values of `t`
outside of the interval [0,1].)
On the other hand, any user who was specifying additional endpoint
tangents simply to get the curve to pass through the right points (i.e.
not requiring exactly the same output) can simply omit the endpoints
that were being supplied only for control purposes.
---
## Discussion
### Design considerations
This is one of the two approaches outlined in #12570 — in this PR, we
are basically declaring that the docs are right and the implementation
was flawed.
One semi-interesting question is how the endpoint tangents actually
ought to be defined when we include them, and another option considered
was mirroring the control points adjacent to the endpoints instead of
duplicating them, which would have had the advantage that the expected
length of the corresponding difference should be more similar to that of
the other difference-tangents, provided that the points are equally
spaced.
In this PR, the duplication method (which produces smaller tangents) was
chosen for a couple reasons:
- It seems to be more standard
- It is exceptionally simple to implement
- I was a little concerned that the aforementioned alternative would
result in some over-extrapolation
### An annoyance
If you look at the code, you'll see I was unable to find a satisfactory
way of doing this without allocating a new vector. This doesn't seem
like a big problem given the context, but it does bother me. In
particular, if there is some easy parallel to `slice::windows` for
iterators that doesn't pull in an external dependency, I would love to
know about it.
# Objective
Lets say I have the following `.meta` file:
```RON
(
meta_format_version: "1.0",
asset: Ignore,
)
```
When a file is inside the `assets` directory and processing is enabled,
the processor will copy the file into `imported_assets` although it
should be ignored and therefore not copied.
## Solution
- I added a simple check that does not copy the assets if the
AssetAction is `Ignore`.
## Migration Guide
- The public `ProcessResult` enum now has a `ProcessResult::Ignore`
variant that must be handled.
# Objective
Fix Pr CI failing over dead code in tests and main branch CI failing
over a missing semicolon. Fixes#12620.
## Solution
Add dead_code annotations and a semicolon.
# Objective
- #12500 use the primary window resolution to do all its calculation.
This means bad support for multiple windows or multiple ui camera
## Solution
- Use camera driven UI (https://github.com/bevyengine/bevy/pull/10559)
# Objective
- since #12500, text is a little bit more gray in UI
## Solution
- don't multiply color by alpha. I think this was done in the original
PR (#8973) for shadows which were not added in #12500
# Objective
- Currently the fps_overlay affects any other ui node spawned. This
should not happen
## Solution
- Use position absolute and a ZIndex of `i32::MAX - 32`
- I also modified the example a little bit to center it correctly. It
only worked previously because the overlay was pushing it down. I also
took the opportunity to simplify the text spawning code a little bit.
# Objective
- #12500 broke images and background colors in UI. Try examples
`overflow`, `ui_scaling` or `ui_texture_atlas`
## Solution
- Makes the component `BorderRadius` optional in the query, as it's not
always present. Use `[0.; 4]` as border radius in the extracted node
when none was found
# Objective
Fixes#12224.
## Solution
- Expand `with_` methods for the `Oklch` to their full names.
- Expand `l` to `lightness` in `Oklaba` comments.
## Migration Guide
The following methods have been renamed for the `Oklch` color space:
- `with_l` -> `with_lightness`.
- `with_c` -> `with_chroma`.
- `with_h` -> `with_hue`.
# Objective
- Many types in bevy_render doesn't reflect Default even if it could.
## Solution
- Reflect it.
---
---------
Co-authored-by: Pablo Reinhardt <pabloreinhardt@gmail.com>
# Objective
- Fixes#12202
## Solution
- This PR implements componentwise (including alpha) addition,
subtraction and scalar multiplication/division for some color types.
- The mentioned color types are `Laba`, `Oklaba`, `LinearRgba` and
`Xyza` as all of them are either physically or perceptually linear as
mentioned by @alice-i-cecile in the issue.
---
## Changelog
- Scalar mul/div for `LinearRgba` may modify alpha now.
## Migration Guide
- Users of scalar mul/div for `LinearRgba` need to be aware of the
change and maybe use the `.clamp()` methods or manually set the `alpha`
channel.
# Objective
Implements border radius for UI nodes. Adopted from #8973, but excludes
shadows.
## Solution
- Add a component `BorderRadius` which contains a radius value for each
corner of the UI node.
- Use a fragment shader to generate the rounded corners using a signed
distance function.

## Changelog
- `BorderRadius`: New component that holds the border radius values.
- `NodeBundle` & `ButtonBundle`: Added a `border_radius: BorderRadius`
field.
- `extract_uinode_borders`: Stripped down, most of the work is done in
the shader now. Borders are no longer assembled from multiple rects,
instead the shader uses a signed distance function to draw the border.
- `UiVertex`: Added size, border and radius fields.
- `UiPipeline`: Added three vertex attributes to the vertex buffer
layout, to accept the UI node's size, border thickness and border
radius.
- Examples: Added rounded corners to the UI element in the `button`
example, and a `rounded_borders` example.

# Objective
- Allow configuring of platform-specific panic handlers.
- Remove the silent overwrite of the WASM panic handler
- Closes#12546
## Solution
- Separates the panic handler to a new plugin, `PanicHandlerPlugin`.
- `PanicHandlerPlugin` was added to `DefaultPlugins`.
- Can be disabled on `DefaultPlugins`, in the case someone needs to
configure custom panic handlers.
---
## Changelog
### Added
- A `PanicHandlerPlugin` was added to the `DefaultPlugins`, which now
sets sensible target-specific panic handlers.
### Changed
- On WASM, the panic stack trace was output to the console through the
`BevyLogPlugin`. Since this was separated out into `PanicHandlerPlugin`,
you may need to add the new `PanicHandlerPlugin` (included in
`DefaultPlugins`).
## Migration Guide
- If you used `MinimalPlugins` with `LogPlugin` for a WASM-target build,
you will need to add the new `PanicHandlerPlugin` to set the panic
behavior to output to the console. Otherwise, you will see the default
panic handler (opaque, `unreachable` errors in the console).
# Objective
- This is an adopted version of #10420
- The objective is to help debugging the Ui layout tree with helpful
outlines, that can be easily enabled/disabled
## Solution
- Like #10420, the solution is using the bevy_gizmos in outlining the
nodes
---
## Changelog
### Added
- Added debug_overlay mod to `bevy_dev_tools`
- Added bevy_ui_debug feature to `bevy_dev_tools`
## How to use
- The user must use `bevy_dev_tools` feature in TOML
- The user must use the plugin UiDebugPlugin, that can be found on
`bevy::dev_tools::debug_overlay`
- Finally, to enable the function, the user must set
`UiDebugOptions::enabled` to true
Someone can easily toggle the function with something like:
```rust
fn toggle_overlay(input: Res<ButtonInput<KeyCode>>, options: ResMut<UiDebugOptions>) {
if input.just_pressed(KeyCode::Space) {
// The toggle method will enable if disabled and disable if enabled
options.toggle();
}
}
```
Note that this feature can be disabled from dev_tools, as its in fact
behind a default feature there, being the feature bevy_ui_debug.
# Limitations
Currently, due to limitations with gizmos itself, it's not possible to
support this feature to more the one window, so this tool is limited to
the primary window only.
# Showcase
Ui example with debug_overlay enabled
And disabled

(mit license) json.
## Discussion
Are there other popular alternatives we should be looking at? Something
new and fancy involving a really long acronym like CIELUVLCh? I'm not a
tailwind user or color expert, but I really like the way it's broken up
into distinct but plentiful hue and lightness groups.
It beats needing some shades of red, scrolling through the [current
palette](https://docs.rs/bevy/latest/bevy/prelude/enum.Color.html),
choosing a few of `CRIMSON`, `MAROON`, `RED`, `TOMATO` at random and
calling it a day.
The best information I was able to dig up about the Tailwind palette is
from this thread:
https://twitter.com/steveschoger/status/1303795136703410180. Here are
some key excerpts:
> Tried to the "perceptually uniform" thing for Tailwind UI.
> Ultimately, it just resulted in a bunch of useless shades for colors
like yellow and green that are inherently brighter.
> With that said you're guaranteed to get a contrast ratio of 4.5:1 when
using any 700 shade (in some cases 600) on a 100 shade of the same hue.
> We just spent a lot of time looking at sites to figure out which
colors are popular and tried to fill all the gaps.
> Even the lime green is questionable but felt there needed to be
something in between the jump from yellow to green 😅

# Objective
Simplify implementing some asset traits without Box::pin(async move{})
shenanigans.
Fixes (in part) https://github.com/bevyengine/bevy/issues/11308
## Solution
Use async-fn in traits when possible in all traits. Traits with return
position impl trait are not object safe however, and as AssetReader and
AssetWriter are both used with dynamic dispatch, you need a Boxed
version of these futures anyway.
In the future, Rust is [adding
](https://blog.rust-lang.org/2023/12/21/async-fn-rpit-in-traits.html)proc
macros to generate these traits automatically, and at some point in the
future dyn traits should 'just work'. Until then.... this seemed liked
the right approach given more ErasedXXX already exist, but, no clue if
there's plans here! Especially since these are public now, it's a bit of
an unfortunate API, and means this is a breaking change.
In theory this saves some performance when these traits are used with
static dispatch, but, seems like most code paths go through dynamic
dispatch, which boxes anyway.
I also suspect a bunch of the lifetime annotations on these function
could be simplified now as the BoxedFuture was often the only thing
returned which needed a lifetime annotation, but I'm not touching that
for now as traits + lifetimes can be so tricky.
This is a revival of
[pull/11362](https://github.com/bevyengine/bevy/pull/11362) after a
spectacular merge f*ckup, with updates to the latest Bevy. Just to recap
some discussion:
- Overall this seems like a win for code quality, especially when
implementing these traits, but a loss for having to deal with ErasedXXX
variants.
- `ConditionalSend` was the preferred name for the trait that might be
Send, to deal with wasm platforms.
- When reviewing be sure to disable whitespace difference, as that's 95%
of the PR.
## Changelog
- AssetReader, AssetWriter, AssetLoader, AssetSaver and Process now use
async-fn in traits rather than boxed futures.
## Migration Guide
- Custom implementations of AssetReader, AssetWriter, AssetLoader,
AssetSaver and Process should switch to async fn rather than returning a
bevy_utils::BoxedFuture.
- Simultaniously, to use dynamic dispatch on these traits you should
instead use dyn ErasedXXX.
# Objective
- Not all materials need shadow, but a queue_shadows system is always
added to the `Render` schedule and executed
## Solution
- Make a setting for shadows, it defaults to true
## Changelog
- Added `shadows_enabled` setting to `MaterialPlugin`
## Migration Guide
- `MaterialPlugin` now has a `shadows_enabled` setting, if you didn't
spawn the plugin using `::default()` or `..default()`, you'll need to
set it. `shadows_enabled: true` is the same behavior as the previous
version, and also the default value.
# Objective
Currently in order to retrieve the inner values from direction types is
that you need to use the `Deref` trait or `From`/`Into`. `Deref` that is
currently implemented is an anti-pattern that I believe should be less
relied upon.
This pull-request add getters for retrieving the inner values for
direction types.
Advantages of getters:
- Let rust-analyzer to list out available methods for users to
understand better to on how to get the inner value. (This happens to me.
I really don't know how to get the value until I look through the source
code.)
- They are simple.
- Generally won't be ambiguous in most context. Traits such as
`From`/`Into` will require fully qualified syntax from time to time.
- Unsurprising result.
Disadvantages of getters:
- More verbose
Advantages of deref polymorphism:
- You reduce boilerplate for getting the value and call inner methods
by:
```rust
let dir = Dir3::new(Vec3::UP).unwrap();
// getting value
let value = *dir;
// instead of using getters
let value = dir.vec3();
// calling methods for the inner vector
dir.xy();
// instead of using getters
dir.vec3().xy();
```
Disadvantages of deref polymorphism:
- When under more level of indirection, it will requires more
dereferencing which will get ugly in some part:
```rust
// getting value
let value = **dir;
// instead of using getters
let value = dir.vec3();
// calling methods for the inner vector
dir.xy();
// instead of using getters
dir.vec3().xy();
```
[More detail
here](https://rust-unofficial.github.io/patterns/anti_patterns/deref.html).
Edit: Update information for From/Into trait.
Edit: Advantages and disadvantages.
## Solution
Add `vec2` method for Dir2.
Add `vec3` method for Dir3.
Add `vec3a` method for Dir3A.
# Objective
prevent gpu buffer allocations when running `as_bind_group` for assets
with texture dependencies that are not yet available.
## Solution
reorder the binding creation so that fallible items are created first.
# Objective
Resolves#12431.
## Solution
Added a `skip_taskbar` field to the `Window` struct (defaults to
`false`). Used in `create_windows` if the target OS is Windows.

<ul>
<li><code>DecodeSliceError::OutputSliceTooSmall</code> is now
conservative rather than precise. That is, the error will only occur if
the decoded output <em>cannot</em> fit, meaning that
<code>Engine::decode_slice</code> can now be used with exactly-sized
output slices. As part of this, <code>Engine::internal_decode</code> now
returns <code>DecodeSliceError</code> instead of
<code>DecodeError</code>, but that is not expected to affect any
external callers.</li>
<li><code>DecodeError::InvalidLength</code> now refers specifically to
the <em>number of valid symbols</em> being invalid (i.e. <code>len % 4
== 1</code>), rather than just the number of input bytes. This avoids
confusing scenarios when based on interpretation you could make a case
for either <code>InvalidLength</code> or <code>InvalidByte</code> being
appropriate.</li>

# Objective
Fixes#12549. WorldCell's support of everything a World can do is
incomplete, and represents an alternative, potentially confusing, and
less performant way of pulling multiple fetches from a `World`. The
typical approach is to use `SystemState` for a runtime cached and safe
way, or `UnsafeWorldCell` if the use of `unsafe` is tolerable.
## Solution
Remove it!
---
## Changelog
Removed: `WorldCell`
Removed: `World::cell`
## Migration Guide
`WorldCell` has been removed. If you were using it to fetch multiple
distinct values from a `&mut World`, use `SystemState` by calling
`SystemState::get` instead. Alternatively, if `SystemState` cannot be
used, `UnsafeWorldCell` can instead be used in unsafe contexts.
# Objective
- working with UI components in Bevy, I found myself wanting some of
these common traits, like `PartialEq` for comparing simple types
## Solution
- I added only (hopefully) uncontroversial `derive`s for some common UI
types
Note that many types, unfortunately, can't have `PartialEq` `derive`d
for them, because they contain `f32`s and / or `Vec`s.
# Objective
I wanted to have reflection for BinaryHeap for a personal project.
I'm running into some issues:
- I wanted to represent BinaryHeap as a reflect::List type since it's
essentially a wrapper around a Vec, however there's no public way to
access the underlying Vec, which makes it hard to implement the
reflect::List methods. I have omitted the reflect::List methods for
now.. I'm not sure if that's a blocker?
- what would be the alternatives? Simply not implement `reflect::List`?
It is possible to implement `FromReflect` without it. Would the type be
`Struct` then?

# Objective
Provide component access to `&'w T`, `Ref<'w, T>`, `Mut<'w, T>`,
`Ptr<'w>` and `MutUntyped<'w>` from `EntityMut<'w>`/`EntityWorldMut<'w>`
with the world `'w` lifetime instead of `'_`.
Fixes#12417
## Solution
Add `into_` prefixed methods for `EntityMut<'w>`/`EntityWorldMut<'w>`
that consume `self` and returns component access with the world `'w`
lifetime unlike the `get_` prefixed methods that takes `&'a self` and
returns component access with `'a` lifetime.
Methods implemented:
- EntityMut::into_borrow
- EntityMut::into_ref
- EntityMut::into_mut
- EntityMut::into_borrow_by_id
- EntityMut::into_mut_by_id
- EntityWorldMut::into_borrow
- EntityWorldMut::into_ref
- EntityWorldMut::into_mut
- EntityWorldMut::into_borrow_by_id
- EntityWorldMut::into_mut_by_id
# Objective
fix#12344
## Solution
use existing machinery in track_assets to determine if the asset is
unused before firing Asset::Unused event
~~most extract functions use `AssetEvent::Removed` to schedule deletion
of render world resources. `RenderAssetPlugin` was using
`AssetEvent::Unused` instead.
`Unused` fires when the last strong handle is dropped, even if a new one
is created. `Removed` only fires when a new one is not created.
as far as i can see, `Unused` is the same as `Removed` except for this
"feature", and that it also fires early if all handles for a loading
asset are dropped (`Removed` fires after the loading completes). note
that in that case, processing based on `Loaded` won't have been done
anyway.
i think we should get rid of `Unused` completely, it is not currently
used anywhere (except here, previously) and i think using it is probably
always a mistake.
i also am not sure why we keep loading assets that have been dropped
while loading, we should probably drop the loader task as well and
remove immediately.~~

Whenever a nodes size gets changed, its texture slices get updated a
frame later. This results in visual glitches when animating the size of
a node with a texture slice. See this video:

# Objective
It's useful to have access to render pipeline statistics, since they
provide more information than FPS alone. For example, the number of
drawn triangles can be used to debug culling and LODs. The number of
fragment shader invocations can provide a more stable alternative metric
than GPU elapsed time.
See also: Render node GPU timing overlay #8067, which doesn't provide
pipeline statistics, but adds a nice overlay.
## Solution
Add `RenderDiagnosticsPlugin`, which enables collecting pipeline
statistics and CPU & GPU timings.

## Changelog
- Add `RenderDiagnosticsPlugin`
- Add `RenderContext::diagnostic_recorder` method

# Objective
`QueryState::archetype_component_access` is only really ever used to
extend `SystemMeta`'s. It can be removed to save some memory for every
`Query` in an app.
## Solution
* Remove it.
* Have `new_archetype` pass in a `&mut Access<ArchetypeComponentId>`
instead and pull it from `SystemMeta` directly.
* Split `QueryState::new` from `QueryState::new_with_access` and a
common `QueryState::new_uninitialized`.
* Split `new_archetype` into an internal and public version. Call the
internal version in `update_archetypes`.
This should make it faster to construct new QueryStates, and by proxy
lenses and joins as well.
`matched_tables` also similarly is only used to deduplicate inserting
into `matched_table_ids`. If we can find another efficient way to do so,
it might also be worth removing.
The [generated
assembly](https://github.com/james7132/bevy_asm_tests/compare/main...remove-query-state-archetype-component-access#diff-496530101f0b16e495b7e9b77c0e906ae3068c8adb69ed36c92d5a1be5a9efbe)
reflects this well, with all of the access related updates in
`QueryState` being removed.
---
## Changelog
Removed: `QueryState::archetype_component_access`.
Changed: `QueryState::new_archetype` now takes a `&mut
Access<ArchetypeComponentId>` argument, which will be updated with the
new accesses.
Changed: `QueryState::update_archetype_component_access` now takes a
`&mut Access<ArchetypeComponentId>` argument, which will be updated with
the new accesses.
## Migration Guide
TODO
# Objective
Improve code quality involving fixedbitset.
## Solution
Update to fixedbitset 0.5. Use the new `grow_and_insert` function
instead of `grow` and `insert` functions separately.
This should also speed up most of the set operations involving
fixedbitset. They should be ~2x faster, but testing this against the
stress tests seems to show little to no difference. The multithreaded
executor doesn't seem to be all that much faster in many_cubes and
many_foxes. These use cases are likely dominated by other operations or
the bitsets aren't big enough to make them the bottleneck.
This introduces a duplicate dependency due to petgraph and wgpu, but the
former may take some time to update.
## Changelog
Removed: `Access::grow`
## Migration Guide
`Access::grow` has been removed. It's no longer needed. Remove all
references to it.
# Objective
Make `Transform` APIs more ergonomic by allowing users to pass `Dir3` as
an argument where a direction is needed. Fixes#12481.
## Solution
Accept `impl TryInto<Dir3>` instead of `Vec3` for direction/axis
arguments in `Transform` APIs
---
## Changelog
The following `Transform` methods now accept an `impl TryInto<Dir3>`
argument where they previously accepted directions as `Vec3`:
* `Transform::{look_to,looking_to}`
* `Transform::{look_at,looking_at}`
* `Transform::{align,aligned_by}`
## Migration Guide
This is not a breaking change since the arguments were previously `Vec3`
which already implements `TryInto<Dir3>`, and behavior is unchanged.

# Objective
- Even if we have `Laba` and `Oklcha` colorspaces using lightness as the
L field name, `Oklaba` doesn't do the same
- The shorthand function for creating a new color should be named
`Oklaba::lab`, but is named `lch`
## Solution
- Rename field l in `Oklaba` to lightness
- Rename `Oklaba::lch` to `Oklaba::lab`
---
## Changelog
### Changed
- Changed name in l field in `Oklaba` to lightness
- Changed method name `Oklaba::lch` to `Oklaba::lab`
## Migration Guide
If you were creating a Oklaba instance directly, instead of using L, you
should use lightness
```rust
// Before
let oklaba = Oklaba { l: 1., ..Default::default() };
// Now
let oklaba = Oklaba { lightness: 1., ..Default::default() };
```
if you were using the function `Oklaba::lch`, now the method is named
`Oklaba::lab`
# Objective
Give easy methods for uniform point sampling in a variety of primitive
shapes (particularly useful for circles and spheres) because in a lot of
cases its quite easy to get wrong (non-uniform).
## Solution
Added the `ShapeSample` trait to `bevy_math` and implemented it for
`Circle`, `Sphere`, `Rectangle`, `Cuboid`, `Cylinder`, `Capsule2d` and
`Capsule3d`. There are a few other shapes it would be reasonable to
implement for like `Triangle`, `Ellipse` and `Torus` but I'm not
immediately sure how these would be implemented (other than rejection
which could be the best method, and could be more performant than some
of the solutions in this pr I'm not sure). This exposes the
`sample_volume` and `sample_surface` methods to get both a random point
from its interior or its surface. EDIT: Renamed `sample_volume` to
`sample_interior` and `sample_surface` to `sample_boundary`
This brings in `rand` as a default optional dependency (without default
features), and the methods take `&mut impl Rng` which allows them to use
any random source implementing `RngCore`.
---
## Changelog
### Added
Added the methods `sample_interior` and `sample_boundary` to a variety
of primitive shapes providing easy uniform point sampling.

# Objective
Fixes#12139
## Solution
- Derive `Debug` impl for `Entity`
- Add impl `Display` for `Entity`
- Add `entity_display` test to check the output contains all required
info
I decided to go with `0v0|1234` format as opposed to the `0v0[1234]`
which was initially discussed in the issue.
My rationale for this is that `[1234]` may be confused for index values,
which may be common in logs, and so searching for entities by text would
become harder. I figured `|1234` would help the entity IDs stand out
more.
Additionally, I'm a little concerned that this change is gonna break
existing logging for projects because `Debug` is now going to be a
multi-line output. But maybe this is ok.
We could implement `Debug` to be a single-line output, but then I don't
see why it would be different from `Display` at all.
@alice-i-cecile Let me know if we'd like to make any changes based on
these points.
# Objective
- Closes#11793
- Introduces a general API for aligning local coordinates of Transforms
with given vectors.
## Solution
- We introduce `Transform::align`, which allows a rotation to be
specified by four pieces of alignment data, as explained by the
documentation:
````rust
/// Rotates this [`Transform`] so that the `main_axis` vector, reinterpreted in local coordinates, points
/// in the given `main_direction`, while `secondary_axis` points towards `secondary_direction`.
///
/// For example, if a spaceship model has its nose pointing in the X-direction in its own local coordinates
/// and its dorsal fin pointing in the Y-direction, then `align(Vec3::X, v, Vec3::Y, w)` will make the spaceship's
/// nose point in the direction of `v`, while the dorsal fin does its best to point in the direction `w`.
///
/// More precisely, the [`Transform::rotation`] produced will be such that:
/// * applying it to `main_axis` results in `main_direction`
/// * applying it to `secondary_axis` produces a vector that lies in the half-plane generated by `main_direction` and
/// `secondary_direction` (with positive contribution by `secondary_direction`)
///
/// [`Transform::look_to`] is recovered, for instance, when `main_axis` is `Vec3::NEG_Z` (the [`Transform::forward`]
/// direction in the default orientation) and `secondary_axis` is `Vec3::Y` (the [`Transform::up`] direction in the default
/// orientation). (Failure cases may differ somewhat.)
///
/// In some cases a rotation cannot be constructed. Another axis will be picked in those cases:
/// * if `main_axis` or `main_direction` is zero, `Vec3::X` takes its place
/// * if `secondary_axis` or `secondary_direction` is zero, `Vec3::Y` takes its place
/// * if `main_axis` is parallel with `secondary_axis` or `main_direction` is parallel with `secondary_direction`,
/// a rotation is constructed which takes `main_axis` to `main_direction` along a great circle, ignoring the secondary
/// counterparts
///
/// Example
/// ```
/// # use bevy_math::{Vec3, Quat};
/// # use bevy_transform::components::Transform;
/// let mut t1 = Transform::IDENTITY;
/// let mut t2 = Transform::IDENTITY;
/// t1.align(Vec3::ZERO, Vec3::Z, Vec3::ZERO, Vec3::X);
/// t2.align(Vec3::X, Vec3::Z, Vec3::Y, Vec3::X);
/// assert_eq!(t1.rotation, t2.rotation);
///
/// t1.align(Vec3::X, Vec3::Z, Vec3::X, Vec3::Y);
/// assert_eq!(t1.rotation, Quat::from_rotation_arc(Vec3::X, Vec3::Z));
/// ```
pub fn align(
&mut self,
main_axis: Vec3,
main_direction: Vec3,
secondary_axis: Vec3,
secondary_direction: Vec3,
) { //... }
````
- We introduce `Transform::aligned_by`, the returning-Self version of
`align`:
````rust
pub fn aligned_by(
mut self,
main_axis: Vec3,
main_direction: Vec3,
secondary_axis: Vec3,
secondary_direction: Vec3,
) -> Self { //... }
````
- We introduce an example (examples/transforms/align.rs) that shows the
usage of this API. It is likely to be mathier than most other
`Transform` APIs, so when run, the example demonstrates what the API
does in space:

## Changelog
- Added methods `align`, `aligned_by` to `Transform`.
- Added transforms/align.rs to examples.
---
## Discussion
### On the form of `align`
The original issue linked above suggests an API similar to that of the
existing `Transform::look_to` method:
````rust
pub fn align_to(&mut self, direction: Vec3, up: Vec3) { //... }
````
Not allowing an input axis of some sort that is to be aligned with
`direction` would not really solve the problem in the issue, since the
user could easily be in a scenario where they have to compose with
another rotation on their own (undesirable). This leads to something
like:
````rust
pub fn align_to(&mut self, axis: Vec3, direction: Vec3, up: Vec3) { //... }
````
However, this still has two problems:
- If the vector that the user wants to align is parallel to the Y-axis,
then the API basically does not work (we cannot fully specify a
rotation)
- More generally, it does not give the user the freedom to specify which
direction is to be treated as the local "up" direction, so it fails as a
general alignment API
Specifying both leads us to the present situation, with two local axis
inputs (`main_axis` and `secondary_axis`) and two target directions
(`main_direction` and `secondary_direction`). This might seem a little
cumbersome for general use, but for the time being I stand by the
decision not to expand further without prompting from users. I'll expand
on this below.
### Additional APIs?
Presently, this PR introduces only `align` and `aligned_by`. Other
potentially useful bundles of API surface arrange into a few different
categories:
1. Inferring direction from position, a la `Transform::look_at`, which
might look something like this:
````rust
pub fn align_at(&mut self, axis: Vec3, target: Vec3, up: Vec3) {
self.align(axis, target - self.translation, Vec3::Y, up);
}
````
(This is simple but still runs into issues when the user wants to point
the local Y-axis somewhere.)
2. Filling in some data for the user for common use-cases; e.g.:
````rust
pub fn align_x(&mut self, direction: Vec3, up: Vec3) {
self.align(Vec3::X, direction, Vec3::Y, up);
}
````
(Here, use of the `up` vector doesn't lose any generality, but it might
be less convenient to specify than something else. This does naturally
leave open the question of what `align_y` would look like if we provided
it.)
Morally speaking, I do think that the `up` business is more pertinent
when the intention is to work with cameras, which the `look_at` and
`look_to` APIs seem to cover pretty well. If that's the case, then I'm
not sure what the ideal shape for these API functions would be, since it
seems like a lot of input would have to be baked into the function
definitions. For some cases, this might not be the end of the world:
````rust
pub fn align_x_z(&mut self, direction: Vec3, weak_direction: Vec3) {
self.align(Vec3::X, direction, Vec3::Z, weak_direction);
}
````
(However, this is not symmetrical in x and z, so you'd still need six
API functions just to support the standard positive coordinate axes, and
if you support negative axes then things really start to balloon.)
The reasons that these are not actually produced in this PR are as
follows:
1. Without prompting from actual users in the wild, it is unknown to me
whether these additional APIs would actually see a lot of use. Extending
these to our users in the future would be trivial if we see there is a
demand for something specific from the above-mentioned categories.
2. As discussed above, there are so many permutations of these that
could be provided that trying to do so looks like it risks unduly
ballooning the API surface for this feature.
3. Finally, and most importantly, creating these helper functions in
user-space is trivial, since they all just involve specializing `align`
to particular inputs; e.g.:
````rust
fn align_ship(ship_transform: &mut Transform, nose_direction: Vec3, dorsal_direction: Vec3) {
ship_transform.align(Ship::NOSE, nose_direction, Ship::DORSAL, dorsal_direction);
}
````
With that in mind, I would prefer instead to focus on making the
documentation and examples for a thin API as clear as possible, so that
users can get a grip on the tool and specialize it for their own needs
when they feel the desire to do so.
### `Dir3`?
As in the case of `Transform::look_to` and `Transform::look_at`, the
inputs to this function are, morally speaking, *directions* rather than
vectors (actually, if we're being pedantic, the input is *really really*
a pair of orthonormal frames), so it's worth asking whether we should
really be using `Dir3` as inputs instead of `Vec3`. I opted for `Vec3`
for the following reasons:
1. Specifying a `Dir3` in user-space is just more annoying than
providing a `Vec3`. Even in the most basic cases (e.g. providing a
vector literal), you still have to do error handling or call an unsafe
unwrap in your function invocations.
2. The existing API mentioned above uses `Vec3`, so we are just adhering
to the same thing.
Of course, the use of `Vec3` has its own downsides; it can be argued
that the replacement of zero-vectors with fixed ones (which we do in
`Transform::align` as well as `Transform::look_to`) more-or-less amounts
to failing silently.
### Future steps
The question of additional APIs was addressed above. For me, the main
thing here to handle more immediately is actually just upstreaming this
API (or something similar and slightly mathier) to `glam::Quat`. The
reason that this would be desirable for users is that this API currently
only works with `Transform`s even though all it's actually doing is
specifying a rotation. Upstreaming to `glam::Quat`, properly done, could
buy a lot basically for free, since a number of `Transform` methods take
a rotation as an input. Using these together would require a little bit
of mathematical savvy, but it opens up some good things (e.g.
`Transform::rotate_around`).
# Objective
- Addresses #12462
- When we serialize an enum, deserialize it, then reserialize it, the
correct variant should be selected.
## Solution
- Change `dynamic_enum.set_variant` to
`dynamic_enum.set_variant_with_index` in `EnumVisitor`
# Objective
- Adds 3d grids, suggestion of #9400
## Solution
- Added 3d grids (grids spanning all three dimensions, not flat grids)
to bevy_gizmos
---
## Changelog
- `gizmos.grid(...)` and `gizmos.grid_2d(...)` now return a
`GridBuilder2d`.
- Added `gizmos.grid_3d(...)` which returns a `GridBuilder3d`.
- The difference between them is basically only that `GridBuilder3d`
exposes some methods for configuring the z axis while the 2d version
doesn't.
- Allowed for drawing the outer edges along a specific axis by calling
`.outer_edges_x()`, etc. on the builder.
## Additional information
Please note that I have not added the 3d grid to any example as not to
clutter them.
Here is an image of what the 3d grid looks like:

Beginning of refactoring of light.rs in bevy_pbr, as per issue #12349
Create and move light.rs to its own directory, and extract AmbientLight
struct.
## Solution
- moved light.rs to light/mod.rs
- extracted AmbientLight struct to light/ambient_light.rs
# Objective
Fixes#12064
## Solution
Prior to #11326, the "global physical" translation of text was rounded.
After #11326, only the "offset" is being rounded.
This moves things around so that the "global translation" is converted
to physical pixels, rounded, and then converted back to logical pixels,
which is what I believe was happening before / what the comments above
describe.
## Discussion
This seems to work and fix an obvious mistake in some code, but I don't
fully grok the ui / text pipelines / math here.
## Before / After and test example

# Objective
`System<f32>` currently does not implement `Eq` even though it should
## Solution
Manually implement `Eq` like other traits are manually implemented
# Objective
To have a user level workaround for #12237.
## Solution
Workaround to the problem is described in:
https://github.com/bevyengine/bevy/issues/12237#issuecomment-1983680632
## Changelog
### Changed
- `CreateWindowParams` type and `create_windows` system from
`bevy_winit` is now public, which allows library authors and game
developers to manually trigger window creation when needed.
# Objective
Fixes#12301. Provide more comprehensive crate level docs for bevy_ptr,
explaining it's methodology and design.
## Solution
Write out said docs.

# Objective
- Reduce allocations on the UI hot path.
## Solution
- Cache buffers used by the `ui_stack_system`.
## Follow-Up
- `sort_by_key` is potentially-allocating. It might be worthwhile to
include the child index as part of the sort-key and use unstable sort.
# Objective
- Closes#11954
## Solution
Change the load_meshes field in `GltfLoaderSettings` from a bool to
`RenderAssetUsages` flag, and add a new load_materials flag.
Use these to determine where the gLTF mesh and material assets are
retained in memory (if the provided flags are empty, then the assets are
skipped during load).
---
## Migration Guide
When loading gLTF assets with `asset_server.load_with_settings`, use
`RenderAssetUsages` instead of `bool` when setting load_meshes e.g.
```rust
let _ = asset_server.load_with_settings("...", |s: &mut GltfLoaderSettings| {
s.load_meshes = RenderAssetUsages::RENDER_WORLD;
});
```
Use the new load_materials field for controlling material load &
retention behaviour instead of load_meshes.
gLTF .meta files need similar updates e.g
```
load_meshes: true,
```
to
```
load_meshes: ("MAIN_WORLD | RENDER_WORLD"),
```

# Objective
Add a `scale_around_center` method to the `BoundingVolume` trait, as per
#12130.
## Solution
Added `scale_around_center` to the `BoundingVolume` trait, implemented
in `Aabb2d`, `Aabb3d`, `BoundingCircle`, and `BoundingSphere` (with
tests).
# Objective
- Fix GamepadEvent::Connection not being sent for devices connected at
startup.
## Solution
- GamepadConnectionEvent was being sent directly for gamepads connected
at startup, which causes consumers of GamepadEvent to not receive those
events.
- Instead send GamepadEvent. The gamepad_event_system splits
GamepadEvent up, so consumers of GamepadConnectionEvent will still
receive the events.
# Objective
- Part of #12351
- Add fps overlay
## Solution
- Create `FpsOverlayPlugin`
- Allow for configuration through resource `FpsOverlayConfig`
- Allow for configuration during runtime

# Objective
- Adds gizmo line joints, suggestion of #9400
## Solution
- Adds `line_joints: GizmoLineJoint` to `GizmoConfig`. Currently the
following values are supported:
- `GizmoLineJoint::None`: does not draw line joints, same behaviour as
previously
- `GizmoLineJoint::Bevel`: draws a single triangle between the lines
- `GizmoLineJoint::Miter` / 'spiky joints': draws two triangles between
the lines extending them until they meet at a (miter) point.
- NOTE: for very small angles between the lines, which happens
frequently in 3d, the miter point will be very far away from the point
at which the lines meet.
- `GizmoLineJoint::Round(resolution)`: Draw a circle arc between the
lines. The circle is a triangle fan of `resolution` triangles.
---
## Changelog
- Added `GizmoLineJoint`, use that in `GizmoConfig` and added necessary
pipelines and draw commands.
- Added a new `line_joints.wgsl` shader containing three vertex shaders
`vertex_bevel`, `vertex_miter` and `vertex_round` as well as a basic
`fragment` shader.
## Migration Guide
Any manually created `GizmoConfig`s must now set the `.line_joints`
field.
## Known issues
- The way we currently create basic closed shapes like rectangles,
circles, triangles or really any closed 2d shape means that one of the
corners will not be drawn with joints, although that would probably be
expected. (see the triangle in the 2d image)
- This could be somewhat mitigated by introducing line caps or fixed by
adding another segment overlapping the first of the strip. (Maybe in a
followup PR?)
- 3d shapes can look 'off' with line joints (especially bevel) because
wherever 3 or more lines meet one of them may stick out beyond the joint
drawn between the other 2.
- Adding additional lines so that there is a joint between every line at
a corner would fix this but would probably be too computationally
expensive.
- Miter joints are 'unreasonably long' for very small angles between the
lines (the angle is the angle between the lines in screen space). This
is technically correct but distracting and does not feel right,
especially in 3d contexts. I think limiting the length of the miter to
the point at which the lines meet might be a good idea.
- The joints may be drawn with a different gizmo in-between them and
their corresponding lines in 2d. Some sort of z-ordering would probably
be good here, but I believe this may be out of scope for this PR.

- The black lines shooting out from the cube are miter joints that get
very long because the lines between which they are drawn are (almost)
collinear in screen space.

# Objective
Rotating vectors is a very common task. It is required for a variety of
things both within Bevy itself and in many third party plugins, for
example all over physics and collision detection, and for things like
Bevy's bounding volumes and several gizmo implementations.
For 3D, we can do this using a `Quat`, but for 2D, we do not have a
clear and efficient option. `Mat2` can be used for rotating vectors if
created using `Mat2::from_angle`, but this is not obvious to many users,
it doesn't have many rotation helpers, and the type does not give any
guarantees that it represents a valid rotation.
We should have a proper type for 2D rotations. In addition to allowing
for potential optimization, it would allow us to have a consistent and
explicitly documented representation used throughout the engine, i.e.
counterclockwise and in radians.
## Representation
The mathematical formula for rotating a 2D vector is the following:
```
new_x = x * cos - y * sin
new_y = x * sin + y * cos
```
Here, `sin` and `cos` are the sine and cosine of the rotation angle.
Computing these every time when a vector needs to be rotated can be
expensive, so the rotation shouldn't be just an `f32` angle. Instead, it
is often more efficient to represent the rotation using the sine and
cosine of the angle instead of storing the angle itself. This can be
freely passed around and reused without unnecessary computations.
The two options are either a 2x2 rotation matrix or a unit complex
number where the cosine is the real part and the sine is the imaginary
part. These are equivalent for the most part, but the unit complex
representation is a bit more memory efficient (two `f32`s instead of
four), so I chose that. This is like Nalgebra's
[`UnitComplex`](https://docs.rs/nalgebra/latest/nalgebra/geometry/type.UnitComplex.html)
type, which can be used for the
[`Rotation2`](https://docs.rs/nalgebra/latest/nalgebra/geometry/type.Rotation2.html)
type.
## Implementation
Add a `Rotation2d` type represented as a unit complex number:
```rust
/// A counterclockwise 2D rotation in radians.
///
/// The rotation angle is wrapped to be within the `]-pi, pi]` range.
pub struct Rotation2d {
/// The cosine of the rotation angle in radians.
///
/// This is the real part of the unit complex number representing the rotation.
pub cos: f32,
/// The sine of the rotation angle in radians.
///
/// This is the imaginary part of the unit complex number representing the rotation.
pub sin: f32,
}
```
Using it is similar to using `Quat`, but in 2D:
```rust
let rotation = Rotation2d::radians(PI / 2.0);
// Rotate vector (also works on Direction2d!)
assert_eq!(rotation * Vec2::X, Vec2::Y);
// Get angle as degrees
assert_eq!(rotation.as_degrees(), 90.0);
// Getting sin and cos is free
let (sin, cos) = rotation.sin_cos();
// "Subtract" rotations
let rotation2 = Rotation2d::FRAC_PI_4; // there are constants!
let diff = rotation * rotation2.inverse();
assert_eq!(diff.as_radians(), PI / 4.0);
// This is equivalent to the above
assert_eq!(rotation2.angle_between(rotation), PI / 4.0);
// Lerp
let rotation1 = Rotation2d::IDENTITY;
let rotation2 = Rotation2d::FRAC_PI_2;
let result = rotation1.lerp(rotation2, 0.5);
assert_eq!(result.as_radians(), std::f32::consts::FRAC_PI_4);
// Slerp
let rotation1 = Rotation2d::FRAC_PI_4);
let rotation2 = Rotation2d::degrees(-180.0); // we can use degrees too!
let result = rotation1.slerp(rotation2, 1.0 / 3.0);
assert_eq!(result.as_radians(), std::f32::consts::FRAC_PI_2);
```
There's also a `From<f32>` implementation for `Rotation2d`, which means
that methods can still accept radians as floats if the argument uses
`impl Into<Rotation2d>`. This means that adding `Rotation2d` shouldn't
even be a breaking change.
---
## Changelog
- Added `Rotation2d`
- Bounding volume methods now take an `impl Into<Rotation2d>`
- Gizmo methods with rotation now take an `impl Into<Rotation2d>`
## Future use cases
- Collision detection (a type like this is quite essential considering
how common vector rotations are)
- `Transform` helpers (e.g. return a 2D rotation about the Z axis from a
`Transform`)
- The rotation used for `Transform2d` (#8268)
- More gizmos, maybe meshes... everything in 2D that uses rotation

# Objective
- Add a way to combine 2 queries together in a similar way to
`Query::transmute_lens`
- Fixes#1658
## Solution
- Use a similar method to query transmute, but take the intersection of
matched archetypes between the 2 queries and the union of the accesses
to create the new underlying QueryState.
---
## Changelog
- Add query joins
---------
Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com>
# Objective
Fix#10876. Improve `Query` and `QueryState`'s docs.
## Solution
Explicitly denote that Query is always guaranteed to return results from
all matching entities once and only once for each entity, and that
iteration order is not guaranteed in any way.
# Objective
Fixes#12402
## Solution
Use `despawn_recursive` instead of `despawn` for despawning
`PlaybackMode::Despawn` audio.
## Migration Guide
`PlaybackSettings::DESPAWN` (`PlaybackMode::Despawn`) now despawns the
audio entity's children as well. If you were relying on the previous
behavior, you may be able to use `PlaybackMode::Remove`, or you may need
to use `PlaybackMode::Once` and manage your audio component lifecycle
manually.
# Objective
- `toml_edit` released a new patch that deprecates `Document`
- this warns when Bevy builds, and CI deny warns
## Solution
- fix deprecation warnings
Updates the requirements on
[ruzstd](https://github.com/KillingSpark/zstd-rs) to permit the latest

Full backtraces (`RUST_BACKTRACE=full`) are unchanged.
## Alternative solutions
Write a custom panic hook. This could potentially let use exclude a few
more callstack frames but requires a dependency on `backtrace` and is
incompatible with user-provided panic hooks.
---
## Changelog
- Backtraces now exclude many Bevy internals (unless
`RUST_BACKTRACE=full` is used)

# Objective
fix occasional crash from commands.insert when quickly spawning and
despawning skinned/morphed meshes
## Solution
use `try_insert` instead of `insert`. if the entity is deleted we don't
mind failing to add the `NoAutomaticBatching` marker.
# Objective
- Fixes https://github.com/bevyengine/bevy/issues/12380
## Solution
- Before #11986 AssetEvents were scheduled after PostUpdate. That pr
moved these into First. This PR moves them into Last which is closer to
how they were scheduled before.
# Objective
- After #12370, ci testing with minimal plugins doesn't hang but it
crash as the resource `ScreenshotManager` doesn't exist
## Solution
- Check if the resource exists
# Objective
Fix missing `TextBundle` (and many others) which are present in the main
crate as default features but optional in the sub-crate. See:
- https://docs.rs/bevy/0.13.0/bevy/ui/node_bundles/index.html
- https://docs.rs/bevy_ui/0.13.0/bevy_ui/node_bundles/index.html
~~There are probably other instances in other crates that I could track
down, but maybe "all-features = true" should be used by default in all
sub-crates? Not sure.~~ (There were many.) I only noticed this because
rust-analyzer's "open docs" features takes me to the sub-crate, not the
main one.
## Solution
Add "all-features = true" to docs.rs metadata for crates that use
features.
## Changelog
### Changed
- Unified features documented on docs.rs between main crate and
sub-crates
