# Objective
Fixes#17098
It seems that it's not totally obvious how to fix this, but that
reverting might be part of the solution anyway.
Let's get the repo back into a working state.
## Solution
Revert the [recent
optimization](https://github.com/bevyengine/bevy/pull/17078) that broke
"many-to-one main->render world entities" for 2d.
## Testing
`cargo run --example text2d`
`cargo run --example sprite_slice`
# Objective
Fixes#3450
## Solution
Scale the input to account for the range
## Testing
Updated unit tests
## Migration Guide
`GamepadButtonChangedEvent.value` is now linearly rescaled to be from
`0.0..=1.0` (instead of `low..=high`) and
`GamepadAxisChangedEvent.value` is now linearly rescaled to be from
`-1.0..=0.0`/`0.0..=1.0` (accounting for the deadzone).
# Objective
We want to deny the following lints:
* `clippy::allow_attributes` - Because there's no reason to
`#[allow(...)]` an attribute if it wouldn't lint against anything; you
should always use `#[expect(...)]`
* `clippy::allow_attributes_without_reason` - Because documenting the
reason for allowing/expecting a lint is always good
## Solution
Set the `clippy::allow_attributes` and
`clippy::allow_attributes_without_reason` lints to `deny`, and bring
`bevy_reflect` in line with the new restrictions.
No code changes have been made - except if a lint that was previously
`allow(...)`'d could be removed via small code changes. For example,
`unused_variables` can be handled by adding a `_` to the beginning of a
field's name.
## Testing
I ran `cargo clippy`, and received no errors.
# Objective
Remove the reliance on `#[allow(clippy::excessive_precision)]`.
## Solution
Remove the `#[allow(clippy::excessive_precision)]`, and truncate the
float literals to the value rustc would normally truncate them to.
## Testing
I ran `cargo test -p bevy_color`, and received no errors.
# Objective
Use the latest version of `typos` and fix the typos that it now detects
# Additional Info
By the way, `typos` has a "low priority typo suggestions issue" where we
can throw typos we find that `typos` doesn't catch.

# Background
In `no_std` compatible crates, there is often an `std` feature which
will allow access to the standard library. Currently, with the `std`
feature _enabled_, the
[`std::prelude`](https://doc.rust-lang.org/std/prelude/index.html) is
implicitly imported in all modules. With the feature _disabled_, instead
the [`core::prelude`](https://doc.rust-lang.org/core/prelude/index.html)
is implicitly imported. This creates a subtle and pervasive issue where
`alloc` items _may_ be implicitly included (if `std` is enabled), or
must be explicitly included (if `std` is not enabled).
# Objective
- Make the implicit imports for `no_std` crates consistent regardless of
what features are/not enabled.
## Solution
- Replace the `cfg_attr` "double negative" `no_std` attribute with
conditional compilation to _include_ `std` as an external crate.
```rust
// Before
#![cfg_attr(not(feature = "std"), no_std)]
// After
#![no_std]
#[cfg(feature = "std")]
extern crate std;
```
- Fix imports that are currently broken but are only now visible with
the above fix.
## Testing
- CI
## Notes
I had previously used the "double negative" version of `no_std` based on
general consensus that it was "cleaner" within the Rust embedded
community. However, this implicit prelude issue likely was considered
when forming this consensus. I believe the reason why is the items most
affected by this issue are provided by the `alloc` crate, which is
rarely used within embedded but extensively used within Bevy.

# Objective
The UI debug overlay draws an outline for every UI node even if it is
invisible or clipped.
Disable debug outlines for hidden and clipped nodes by default and add
options to renable them if needed.
## Solution
* Add `show_hidden` and `show_clipped` fields to `UiDebugOptions`:
```rust
/// Show outlines for non-visible UI nodes
pub show_hidden: bool,
/// Show outlines for clipped sections of UI nodes
pub show_clipped: bool,
```
* Only extract debug outlines for hidden and clipped UI nodes if the
respective field in `UiDebugOptions` is set to `true`.
## Testing
Also added some extra features to the `testbed_ui` example that
demonstrate the new options:
cargo run --example testbed_ui --features "bevy_ui_debug"

# Objective
- Fixes https://github.com/bevyengine/bevy/issues/16556
- Closes https://github.com/bevyengine/bevy/issues/11807
## Solution
- Simplify custom projections by using a single source of truth -
`Projection`, removing all existing generic systems and types.
- Existing perspective and orthographic structs are no longer components
- I could dissolve these to simplify further, but keeping them around
was the fast way to implement this.
- Instead of generics, introduce a third variant, with a trait object.
- Do an object safety dance with an intermediate trait to allow cloning
boxed camera projections. This is a normal rust polymorphism papercut.
You can do this with a crate but a manual impl is short and sweet.
## Testing
- Added a custom projection example
---
## Showcase
- Custom projections and projection handling has been simplified.
- Projection systems are no longer generic, with the potential for many
different projection components on the same camera.
- Instead `Projection` is now the single source of truth for camera
projections, and is the only projection component.
- Custom projections are still supported, and can be constructed with
`Projection::custom()`.
## Migration Guide
- `PerspectiveProjection` and `OrthographicProjection` are no longer
components. Use `Projection` instead.
- Custom projections should no longer be inserted as a component.
Instead, simply set the custom projection as a value of `Projection`
with `Projection::custom()`.
# Objective
- As stated in the related issue, this PR is to better align the feature
flag name with what it actually does and the plans for the future.
- Fixes#16852
## Solution
- Simple find / replace
## Testing
- Local run of `cargo run -p ci`
## Migration Guide
The `track_change_detection` feature flag has been renamed to
`track_location` to better reflect its extended capabilities.
# Objective
- Fix sprite rendering performance regression since retained render
world changes
- The retained render world changes moved `ExtractedSprites` from using
the highly-optimised `EntityHasher` with an `Entity` to using
`FixedHasher` with `(Entity, MainEntity)`. This was enough to regress
framerate in bevymark by 25%.
## Solution
- Move the render world entity into a member of `ExtractedSprite` and
change `ExtractedSprites` to use `MainEntityHashMap` for its storage
- Disable sprite picking in bevymark

## Migration Guide
- `ExtractedSprites` is now using `MainEntityHashMap` for storage, which
is keyed on `MainEntity`.
- The render world entity corresponding to an `ExtractedSprite` is now
stored in the `render_entity` member of it.
# Objective
Remove the `atlas_scaling` field from `ExtractedUiItem::Gylphs`.
It's only ever set to `Vec2::ONE`. I don't remember why/if this field
was ever needed, maybe it was useful before the scale factor clean up.
## Migration Guide
The `atlas_scaling` field from `ExtractedUiItem::Gylphs` has been
removed. This shouldn't affect any existing code as it wasn't used for
anything.
# Objective
Tab navigation can fail in all manner of ways. The current API
recognizes this, but merely logs a warning and returns `None`.
We should supply the actual reason for failure to the caller, so they
can handle it in whatever fashion they please (including logging a
warning!).
Swapping to a Result-oriented pattern is also a bit more idiomatic and
makes the code's control flow easier to follow.
## Solution
- Refactor the `tab_navigation` module to return a `Result` rather than
an `Option` from its key APIs.
- Move the logging to the provided prebuilt observer. This leaves the
default behavior largely unchanged, but allows for better user control.
- Make the case where no tab group was found for the currently focused
entity an error branch, but provide enough information that we can still
recover from it.
## Testing
The `tab_navigation` example continues to function as intended.
# Objective
Resolves#17064
## Solution
- Bevy no longer converts asset file extensions to lowercase before
trying to resolve an asset loader
## Testing
- I adapted the `custom_asset` example (see comment in #17064)
- The changes were tested on Linux
As far as I know, Windows has a case-insensitive file system by default,
so case-sensitive asset file extensions are probably bad practice in a
game. But we should be case-sensitive everywhere or handle asset paths
completely case-insensitive.
Before this PR:
* asset loader extensions are case-sensitive
* asset file names are case-sensitive
* asset file extensions are converted to lowercase ⚡
Now everything should be case-sensitive
# Objective
Following #16876, `bevy_input_focus` works with more than just keyboard
inputs! The docs should reflect that.
## Solution
Fix a few missed mentions in the documentation.
Also add a brief reference to navigation frameworks within the module
docs to help give more breadcrumbs.
# Objective
- Support more ergonomic conditional updates for types that can be
modified by `clone_into`.
## Solution
- Use `ToOwned::clone_into` to copy a reference provided by the caller
in `Mut::clone_from_if_neq`.
## Testing
- See doc tests.
# Objective
- #16589 added an enum to switch between fallible and infallible system.
This branching should be unnecessary if we wrap infallible systems in a
function to return `Ok(())`.
## Solution
- Create a wrapper system for `System<(), ()>`s that returns `Ok` on the
call to `run` and `run_unsafe`. The wrapper should compile out, but I
haven't checked.
- I removed the `impl IntoSystemConfigs for BoxedSystem<(), ()>` as I
couldn't figure out a way to keep the impl without double boxing.
## Testing
- ran `many_foxes` example to check if it still runs.
## Migration Guide
- `IntoSystemConfigs` has been removed for `BoxedSystem<(), ()>`. Either
use `InfallibleSystemWrapper` before boxing or make your system return
`bevy::ecs::prelude::Result`.
# Objective
It is not obvious that one would know these:
```json
{
"id": 1,
"jsonrpc": "2.0",
"result": [
"bevy_animation::AnimationPlayer",
"bevy_animation::AnimationTarget",
"bevy_animation::graph::AnimationGraphHandle",
"bevy_animation::transition::AnimationTransitions",
"bevy_audio::audio::PlaybackSettings",
"bevy_audio::audio::SpatialListener",
"bevy_core_pipeline::bloom::settings::Bloom",
"bevy_core_pipeline::contrast_adaptive_sharpening::ContrastAdaptiveSharpening",
**... snipping for brevity ...**
"bevy_ui::ui_node::Node",
"bevy_ui::ui_node::Outline",
"bevy_ui::ui_node::ScrollPosition",
"bevy_ui::ui_node::TargetCamera",

"bevy_window:🪟:PrimaryWindow",
"bevy_window:🪟:Window",
"bevy_winit::cursor::CursorIcon",
"server::Cube"
]
}
```
Especially if you for example, are reading the GH examples because:
If you for example expand these things, due to the number of places bevy
re-exports things you'll find it difficult to find the true path of
something.
i.e you'd probably be forgiven for writing a query (using the
`client.rs` example):
```sh
$ cargo run --example client -- bevy_pbr::mesh_material::MeshMaterial3d | jq
{
"error": {
"code": -23402,
"message": "Unknown component type: `bevy_pbr::mesh_material::MeshMaterial3d`"
},
"id": 1,
"jsonrpc": "2.0"
}
```
which is where
8d9a00f548/crates/bevy_pbr/src/mesh_material.rs (L41)
would lead you to believe it is...
I've worked with bevy a lot, so it's no issue for me, but for others...
?

# Objective
- Make working with immutable components more ergonomic
- Assist #16662
## Solution
Added `modify_component` to `World` and `EntityWorldMut`. This method
"removes" a component from an entity, gives a mutable reference to it to
a provided closure, and then "re-inserts" the component back onto the
entity. This replacement triggers the `OnReplace` and `OnInsert` hooks,
but does _not_ cause an archetype move, as the removal is purely
simulated.
## Testing
- Added doc-tests and a unit test.
---
## Showcase
```rust
use bevy_ecs::prelude::*;
/// An immutable component.
#[derive(Component, PartialEq, Eq, Debug)]
#[component(immutable)]
struct Foo(bool);
let mut world = World::default();
let mut entity = world.spawn(Foo(false));
assert_eq!(entity.get::<Foo>(), Some(&Foo(false)));
// Before the closure is executed, the `OnReplace` hooks/observers are triggered
entity.modify_component(|foo: &mut Foo| {
foo.0 = true;
});
// After the closure is executed, `OnInsert` hooks/observers are triggered
assert_eq!(entity.get::<Foo>(), Some(&Foo(true)));
```
## Notes
- If the component is not available on the entity, the closure and hooks
aren't executed, and `None` is returned. I chose this as an alternative
to returning an error or panicking, but I'm open to changing that based
on feedback.
- This relies on `unsafe`, in particular for accessing the `Archetype`
to trigger hooks. All the unsafe operations are contained within
`DeferredWorld::modify_component`, and I would appreciate that this
function is given special attention to ensure soundness.
- The `OnAdd` hook can never be triggered by this method, since the
component must already be inserted. I have chosen to not trigger
`OnRemove`, as I believe it makes sense that this method is purely a
replacement operation, not an actual removal/insertion.

# Objective
- Made certain methods public for advanced use cases. Methods that
returns mutable references are marked as unsafe due to the possibility
of violating internal lifetime constraint assumptions.
- Fixes an issue introduced by #15184
# Objective
- Resolve several warnings encountered when compiling for `no_std`
around `dead_code`
- Fix compatibility with `wasm32-unknown-unknown` when using `no_std`
(identified by Sachymetsu on
[Discord](https://discord.com/channels/691052431525675048/692572690833473578/1323365426901549097))
## Solution
- Removed some unused imports
- Added `allow(dead_code)` for certain private items when compiling on
`no_std`
- Fixed `bevy_app` and `bevy_tasks` compatibility with WASM when
compiling without `std` by appropriately importing `Box` and feature
gating panic unwinding
## Testing
- CI
# Objective
Some sort calls and `Ord` impls are unnecessarily complex.
## Solution
Rewrite the "match on cmp, if equal do another cmp" as either a
comparison on tuples, or `Ordering::then_with`, depending on whether the
compare keys need construction.
`sort_by` -> `sort_by_key` when symmetrical. Do the same for
`min_by`/`max_by`.
Note that `total_cmp` can only work with `sort_by`, and not on tuples.
When sorting collected query results that contain
`Entity`/`MainEntity`/`RenderEntity` in their `QueryData`, with that
`Entity` in the sort key:
stable -> unstable sort (all queried entities are unique)
If key construction is not simple, switch to `sort_by_cached_key` when
possible.
Sorts that are only performed to discover the maximal element are
replaced by `max_by_key`.
Dedicated comparison functions and structs are removed where simple.
Derive `PartialOrd`/`Ord` when useful.
Misc. closure style inconsistencies.
## Testing
- Existing tests.
# Objective
In `prepare_sprite_image_bind_groups` the `batch_image_changed`
condition is checked twice but the second if-block seems unnecessary.
# Solution
Queue new `SpriteBatch`es inside the first if-block and remove the
second if-block.
# Objective
- Contributes to #15460
## Solution
- Added the following features:
- `std` (default)
- `alloc` (default)
- `bevy_reflect` (default)
- `libm`
## Testing
- CI
## Notes
- `alloc` feature added to allow using this crate in `no_alloc`
environments.
- `bevy_reflect` was previously always enabled when `bevy-support` was
enabled, which isn't how most other crates handle reflection. I've
brought this in line with how most crates gate `bevy_reflect`.
# Objective
Fixes#17024
## Solution
## Testing
By adding
```
if let Some(mut cmd) = commands.get_entity( *equipment_link_node ){
cmd.insert(Visibility::Inherited); // a hack for now
}
```
in my build after .set_parent() , this fixes the issue. This is why i
think that this change will fix the issue. Unfortunately i was not able
to test the Changed (parent ) , this actual code change, because no
matter how i 'patch', it breaks my project. I got super close but still
had 23 errors due to Reflect being angry.

# Objective
Make working with `PluginGroupBuilder` less panicky.
Fixes#17001
## Solution
Expand the `PluginGroupBuilder` api with fallible add methods + a
contains method.
Also reorder the `PluginGroupBuilder` tests because before should come
before after.
## Testing
Ran the `PluginGroupBuilder` tests which call into all the newly added
methods.
This commit makes the following changes:
* `IndirectParametersBuffer` has been changed from a `BufferVec` to a
`RawBufferVec`. This won about 20us or so on Bistro by avoiding `encase`
overhead.
* The methods on the `GetFullBatchData` trait no longer have the
`entity` parameter, as it was unused.
* `PreprocessWorkItem`, which specifies a transform-and-cull operation,
now supplies the mesh instance uniform output index directly instead of
having the shader look it up from the indirect draw parameters.
Accordingly, the responsibility of writing the output index to the
indirect draw parameters has been moved from the CPU to the GPU. This is
in preparation for retained indirect instance draw commands, where the
mesh instance uniform output index may change from frame to frame, while
the indirect instance draw commands will be cached. We won't want the
CPU to have to upload the same indirect draw parameters again and again
if a batch didn't change from frame to frame.
* `batch_and_prepare_binned_render_phase` and
`batch_and_prepare_sorted_render_phase` now allocate indirect draw
commands for an entire batch set at a time when possible, instead of one
batch at a time. This change will allow us to retain the indirect draw
commands for whole batch sets.
* `GetFullBatchData::get_batch_indirect_parameters_index` has been
replaced with `GetFullBatchData::write_batch_indirect_parameters`, which
takes an offset and writes into it instead of allocating. This is
necessary in order to use the optimization mentioned in the previous
point.
* At the WGSL level, `IndirectParameters` has been factored out into
`mesh_preprocess_types.wgsl`. This is because we'll need a new compute
shader that zeroes out the instance counts in preparation for a new
frame. That shader will need to access `IndirectParameters`, so it was
moved to a separate file.
* Bins are no longer raw vectors but are instances of a separate type,
`RenderBin`. This is so that the bin can eventually contain its retained
batches.
OK, so this is tricky. Every frame, `delete_old_work_item_buffers`
deletes the mesh preprocessing index buffers (a.k.a. work item buffers)
for views that don't have `ViewTarget`s. This was always wrong for
shadow map views, as shadow maps only have `ExtractedView` components,
not `ViewTarget`s. However, before #16836, the problem was masked,
because uploading the mesh preprocessing index buffers for shadow views
had already completed by the time `delete_old_work_item_buffers` ran.
But PR #16836 moved `delete_old_work_item_buffers` from the
`ManageViews` phase to `PrepareResources`, which runs before
`write_batched_instance_buffers` uploads the work item buffers to the
GPU.
This itself isn't wrong, but it exposed the bug, because now it's
possible for work item buffers to get deleted before they're uploaded in
`write_batched_instance_buffers`. This is actually intermittent! It's
possible for the old work item buffers to get deleted, and then
*recreated* in `batch_and_prepare_binned_render_phase`, which runs
during `PrepareResources` as well, and under that system ordering, there
will be no problem other than a little inefficiency arising from
recreating the buffers every frame. But, if
`delete_old_work_item_buffers` runs *after*
`batch_and_prepare_render_phase`, then the work item buffers
corresponding to shadow views will get deleted, and then the shadows
will disappear.
The fact that this is racy is what made it look like #16922 solved the
issue. In fact, it didn't: it just perturbed the ordering on the build
bots enough that the issue stopped appearing. However, on my system, the
shadows still don't appear with #16922.
This commit solves the problem by making `delete_old_work_item_buffers`
look at `ExtractedView`s, not `ViewTarget`s, preventing work item
buffers corresponding to live shadow map views from being deleted.
# Objective
Fix alignment calculations in our rendering code.
Fixes#16992
The `gpu_readback::align_byte_size` function incorrectly rounds aligned
values to the next alignment.
If we assume the alignment to be 256 (because that's what wgpu says it
its) the function would align 0 to 256, 256 to 512, etc...
## Solution
Forward the `gpu_readback::align_byte_size` to
`RenderDevice::align_copy_bytes_per_row` so we don't implement the same
method twice.
Simplify `RenderDevice::align_copy_bytes_per_row`.
## Testing
Ran the code provided in #16992 to see if the issue has been solved +
added a test to check if `align_copy_bytes_per_row` returns the correct
values.
