# Objective
- Custom render passes, or future passes in the engine (such as
https://github.com/bevyengine/bevy/pull/10164) need a better way to know
and indicate to the core passes whether the view color/depth/prepass
attachments have been cleared or not yet this frame, to know if they
should clear it themselves or load it.
## Solution
- For all render targets (depth textures, shadow textures, prepass
textures, main textures) use an atomic bool to track whether or not each
texture has been cleared this frame. Abstracted away in the new
ColorAttachment and DepthAttachment wrappers.
---
## Changelog
- Changed `ViewTarget::get_color_attachment()`, removed arguments.
- Changed `ViewTarget::get_unsampled_color_attachment()`, removed
arguments.
- Removed `Camera3d::clear_color`.
- Removed `Camera2d::clear_color`.
- Added `Camera::clear_color`.
- Added `ExtractedCamera::clear_color`.
- Added `ColorAttachment` and `DepthAttachment` wrappers.
- Moved `ClearColor` and `ClearColorConfig` from
`bevy::core_pipeline::clear_color` to `bevy::render::camera`.
- Core render passes now track when a texture is first bound as an
attachment in order to decide whether to clear or load it.
## Migration Guide
- Remove arguments to `ViewTarget::get_color_attachment()` and
`ViewTarget::get_unsampled_color_attachment()`.
- Configure clear color on `Camera` instead of on `Camera3d` and
`Camera2d`.
- Moved `ClearColor` and `ClearColorConfig` from
`bevy::core_pipeline::clear_color` to `bevy::render::camera`.
- `ViewDepthTexture` must now be created via the `new()` method

# Objective
Fix ci hang, so we can merge pr's again.
## Solution
- switch ppa action to use mesa stable versions
https://launchpad.net/~kisak/+archive/ubuntu/turtle
- use commit from #11123

# Objective
- Provides an alternate solution to the one implemented in #10791
without breaking changes.
## Solution
- Changes the bounds of macro-generated `TypePath` implementations to
universally ignore the types of fields, rather than use the same bounds
as other implementations. I think this is a more holistic solution than
#10791 because it totally erases the finicky bounds we currently
generate, helping to untangle the reflection trait system.
# Objective
- Make the implementation order consistent between all sources to fit
the order in the trait.
## Solution
- Change the implementation order.
Matches versioning & features from other Cargo.toml files in the
project.
# Objective
Resolves#10932
## Solution
Added smallvec to the bevy_utils cargo.toml and added a line to
re-export the crate. Target version and features set to match what's
used in the other bevy crates.
# Objective
Register and Serialize `Camera3dDepthTextureUsage` and
`ScreenSpaceTransmissionQuality`.
Fixes: #11036
## Solution
Added the relevant derives for reflection and serialization and type
registrations.
# Objective
Outlines are drawn for UI nodes with `Display::None` set and their
descendants. They should not be visible.
## Solution
Make all Nodes with `Display::None` inherit an empty clipping rect,
ensuring that the outlines are not visible.
Fixes#10940
---
## Changelog
* In `update_clipping_system` if a node has `Display::None` set, clip
the entire node and all its descendants by replacing the inherited clip
with a default rect (which is empty)
# Objective
The documentation for the `States` trait contains an error! There is a
single colon missing from `OnExit<T:Variant>`.
## Solution
Replace `OnExit<T:Variant>` with `OnExit<T::Variant>`. (Notice the added
colon.)
---
## Changelog
### Added
- Added missing colon in `States` documentation.
---
Bevy community, you may now rest easy.
The error conditions were not documented, this requires the user to
inspect the source code to know when to expect a `None`.
Error conditions should always be documented, so we document them.

Improves #11052
# Changelog
- Remove `Window::fit_canvas_to_parent`, as its resizing on wasm now
respects its CSS configuration.
## Migration Guide
- Remove uses of `Window::fit_canvas_to_parent` in favor of CSS
properties, for example:
```css
canvas {
width: 100%;
height: 100%;
}
```
# Objective
- After #10336, some gltf files fail to load (examples
custom_gltf_vertex_attribute, gltf_skinned_mesh, ...)
- Fix them
## Solution
- Allow padding in base 64 decoder
# Objective
Fix#10731.
## Solution
Rename `App::add_state<T>(&mut self)` to `init_state`, and add
`App::insert_state<T>(&mut self, state: T)`. I decided on these names
because they are more similar to `init_resource` and `insert_resource`.
I also removed the `States` trait's requirement for `Default`. Instead,
`init_state` requires `FromWorld`.
---
## Changelog
- Renamed `App::add_state` to `init_state`.
- Added `App::insert_state`.
- Removed the `States` trait's requirement for `Default`.
## Migration Guide
- Renamed `App::add_state` to `init_state`.
# Objective
- Update winit dependency to 0.29
## Changelog
### KeyCode changes
- Removed `ScanCode`, as it was [replaced by
KeyCode](https://github.com/rust-windowing/winit/blob/master/CHANGELOG.md#0292).
- `ReceivedCharacter.char` is now a `SmolStr`, [relevant
doc](https://docs.rs/winit/latest/winit/event/struct.KeyEvent.html#structfield.text).
- Changed most `KeyCode` values, and added more.
KeyCode has changed meaning. With this PR, it refers to physical
position on keyboard rather than the printed letter on keyboard keys.
In practice this means:
- On QWERTY keyboard layouts, nothing changes
- On any other keyboard layout, `KeyCode` no longer reflects the label
on key.
- This is "good". In bevy 0.12, when you used WASD for movement, users
with non-QWERTY keyboards couldn't play your game! This was especially
bad for non-latin keyboards. Now, WASD represents the physical keys. A
French player will press the ZQSD keys, which are near each other,
Kyrgyz players will use "Цфыв".
- This is "bad" as well. You can't know in advance what the label of the
key for input is. Your UI says "press WASD to move", even if in reality,
they should be pressing "ZQSD" or "Цфыв". You also no longer can use
`KeyCode` for text inputs. In any case, it was a pretty bad API for text
input. You should use `ReceivedCharacter` now instead.
### Other changes
- Use `web-time` rather than `instant` crate.
(https://github.com/rust-windowing/winit/pull/2836)
- winit did split `run_return` in `run_onDemand` and `pump_events`, I
did the same change in bevy_winit and used `pump_events`.
- Removed `return_from_run` from `WinitSettings` as `winit::run` now
returns on supported platforms.
- I left the example "return_after_run" as I think it's still useful.
- This winit change is done partly to allow to create a new window after
quitting all windows: https://github.com/emilk/egui/issues/1918 ; this
PR doesn't address.
- added `width` and `height` properties in the `canvas` from wasm
example
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1420567168)
## Known regressions (important follow ups?)
- Provide an API for reacting when a specific key from current layout
was released.
- possible solutions: use winit::Key from winit::KeyEvent ; mapping
between KeyCode and Key ; or .
- We don't receive characters through alt+numpad (e.g. alt + 151 = "ù")
anymore ; reproduced on winit example "ime". maybe related to
https://github.com/rust-windowing/winit/issues/2945
- (windows) Window content doesn't refresh at all when resizing. By
reading https://github.com/rust-windowing/winit/issues/2900 ; I suspect
we should just fire a `window.request_redraw();` from `AboutToWait`, and
handle actual redrawing within `RedrawRequested`. I'm not sure how to
move all that code so I'd appreciate it to be a follow up.
- (windows) unreleased winit fix for using set_control_flow in
AboutToWait https://github.com/rust-windowing/winit/issues/3215 ; ⚠️ I'm
not sure what the implications are, but that feels bad 🤔
## Follow up
I'd like to avoid bloating this PR, here are a few follow up tasks
worthy of a separate PR, or new issue to track them once this PR is
closed, as they would either complicate reviews, or at risk of being
controversial:
- remove CanvasParentResizePlugin
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1417068856)
- avoid mentionning explicitly winit in docs from bevy_window ?
- NamedKey integration on bevy_input:
https://github.com/rust-windowing/winit/pull/3143 introduced a new
NamedKey variant. I implemented it only on the converters but we'd
benefit making the same changes to bevy_input.
- Add more info in KeyboardInput
https://github.com/bevyengine/bevy/pull/10702#pullrequestreview-1748336313
- https://github.com/bevyengine/bevy/pull/9905 added a workaround on a
bug allegedly fixed by winit 0.29. We should check if it's still
necessary.
- update to raw_window_handle 0.6
- blocked by wgpu
- Rename `KeyCode` to `PhysicalKeyCode`
https://github.com/bevyengine/bevy/pull/10702#discussion_r1404595015
- remove `instant` dependency, [replaced
by](https://github.com/rust-windowing/winit/pull/2836) `web_time`), we'd
need to update to :
- fastrand >= 2.0
- [`async-executor`](https://github.com/smol-rs/async-executor) >= 1.7
- [`futures-lite`](https://github.com/smol-rs/futures-lite) >= 2.0
- Verify license, see
[discussion](https://github.com/bevyengine/bevy/pull/8745#discussion_r1402439800)
- we might be missing a short notice or description of changes made
- Consider using https://github.com/rust-windowing/cursor-icon directly
rather than vendoring it in bevy.
- investigate [this
unwrap](https://github.com/bevyengine/bevy/pull/8745#discussion_r1387044986)
(`winit_window.canvas().unwrap();`)
- Use more good things about winit's update
- https://github.com/bevyengine/bevy/pull/10689#issuecomment-1823560428
## Migration Guide
This PR should have one.
# Objective
- Update base64 requirement from 0.13.0 to 0.21.5.
- Closes#10317.
## Solution
- Bumped `base64` requirement and manually migrated code to fix a
breaking change after updating.
# Objective
`Has<T>` in some niche cases may behave in an unexpected way.
Specifically, when using `Query::get` on a `Has<T>` with a despawned
entity.
## Solution
Add precision about cases wehre `Query::get` could return an `Err`.
Use `'w` for world lifetime consistently.
When implementing system params, useful to look at how other params are
implemented. `'w` makes it clear it is world, not state.
# Objective
- Fixes#10587, where the `Aabb` component of entities with `Sprite` and
`Handle<Image>` components was not automatically updated when
`Sprite::custom_size` changed.
## Solution
- In the query for entities with `Sprite` components in
`calculate_bounds_2d`, use the `Changed` filter to detect for `Sprites`
that changed as well as sprites that do not have `Aabb` components. As
noted in the issue, this will cause the `Aabb` to be recalculated when
other fields of the `Sprite` component change, but calculating the
`Aabb` for sprites is trivial.
---
## Changelog
- Modified query for entities with `Sprite` components in
`calculate_bounds_2d`, so that entities with `Sprite` components that
changed will also have their AABB recalculated.
# Objective
- Provide way to check whether multiple inputs are pressed.
## Solution
- Add `all_pressed` method that checks if all inputs are currently being
pressed.
# Objective
- Allow checking if a resource has changed by its ComponentId
---
## Changelog
- Added `World::is_resource_changed_by_id()` and
`World::is_resource_added_by_id()`.
# Objective
Being able to do:
```rust
ev_scene_ready.read().next().unwrap();
```
Which currently isn't possible because `SceneInstanceReady` doesn't
implement `Debug`.
## Solution
Implement `Debug` for `SceneInstanceReady`.
---
## Changelog
### Added
- Implement Std traits for `SceneInstanceReady`.
# Objective
- Fix an inconsistency in the calculation of aspect ratio's.
- Fixes#10288
## Solution
- Created an intermediate `AspectRatio` struct, as suggested in the
issue. This is currently just used in any places where aspect ratio
calculations happen, to prevent doing it wrong. In my and @mamekoro 's
opinion, it would be better if this was used instead of a normal `f32`
in various places, but I didn't want to make too many changes to begin
with.
## Migration Guide
- Anywhere where you are currently expecting a f32 when getting aspect
ratios, you will now receive a `AspectRatio` struct. this still holds
the same value.

# Objective
The definition of several `QueryState` methods use unnecessary explicit
lifetimes, which adds to visual noise.
## Solution
Elide the lifetimes.
# Objective
- bevy_sprite crate is missing docs for important types. `Sprite` being
undocumented was especially confusing for me even though it is one of
the first types I need to learn.
## Solution
- Improves the situation a little by adding some documentations.
I'm unsure about my understanding of functionality and writing. I'm
happy to be pointed out any mistakes.

# Objective
`Instant` and `Duration` from the `instant` crate are exposed in
`bevy_utils` to have a single abstraction for native/wasm.
It would be useful to have the same thing for
[`SystemTime`](https://doc.rust-lang.org/std/time/struct.SystemTime.html).
---
## Changelog
### Added
- `bevy_utils` now re-exposes the `instant::SystemTime` struct
Co-authored-by: Charles Bournhonesque <cbournhonesque@snapchat.com>
# Objective
- Users are often confused when their command effects are not visible in
the next system. This PR auto inserts sync points if there are deferred
buffers on a system and there are dependents on that system (systems
with after relationships).
- Manual sync points can lead to users adding more than needed and it's
hard for the user to have a global understanding of their system graph
to know which sync points can be merged. However we can easily calculate
which sync points can be merged automatically.
## Solution
1. Add new edge types to allow opting out of new behavior
2. Insert an sync point for each edge whose initial node has deferred
system params.
3. Reuse nodes if they're at the number of sync points away.
* add opt outs for specific edges with `after_ignore_deferred`,
`before_ignore_deferred` and `chain_ignore_deferred`. The
`auto_insert_apply_deferred` boolean on `ScheduleBuildSettings` can be
set to false to opt out for the whole schedule.
## Perf
This has a small negative effect on schedule build times.

```
---
## Changelog
- Auto insert sync points and added `after_ignore_deferred`,
`before_ignore_deferred`, `chain_no_deferred` and
`auto_insert_apply_deferred` APIs to opt out of this behavior
## Migration Guide
- `apply_deferred` points are added automatically when there is ordering
relationship with a system that has deferred parameters like `Commands`.
If you want to opt out of this you can switch from `after`, `before`,
and `chain` to the corresponding `ignore_deferred` API,
`after_ignore_deferred`, `before_ignore_deferred` or
`chain_ignore_deferred` for your system/set ordering.
- You can also set `ScheduleBuildSettings::auto_insert_sync_points` to
`false` if you want to do it for the whole schedule. Note that in this
mode you can still add `apply_deferred` points manually.
- For most manual insertions of `apply_deferred` you should remove them
as they cannot be merged with the automatically inserted points and
might reduce parallelizability of the system graph.
## TODO
- [x] remove any apply_deferred used in the engine
- [x] ~~decide if we should deprecate manually using apply_deferred.~~
We'll still allow inserting manual sync points for now for whatever edge
cases users might have.
- [x] Update migration guide
- [x] rerun schedule build benchmarks

# Objective
Make direction construction a bit more ergonomic.
## Solution
Add `Direction2d::from_xy` and `Direction3d::from_xyz`, similar to
`Transform::from_xyz`:
```rust
let dir2 = Direction2d::from_xy(0.5, 0.5).unwrap();
let dir3 = Direction3d::from_xyz(0.5, 0.5, 0.5).unwrap();
```
This can be a bit cleaner than using `new`:
```rust
let dir2 = Direction2d::new(Vec2::new(0.5, 0.5)).unwrap();
let dir3 = Direction3d::new(Vec3::new(0.5, 0.5, 0.5)).unwrap();
```
Fixes https://github.com/bevyengine/bevy/issues/10974
# Objective
Duplicate the ordering logic of the `Main` schedule into the `FixedMain`
schedule.
---
## Changelog
- `FixedUpdate` is no longer the main schedule ran in
`RunFixedUpdateLoop`, `FixedMain` has replaced this and has a similar
structure to `Main`.
## Migration Guide
- Usage of `RunFixedUpdateLoop` should be renamed to `RunFixedMainLoop`.
# Objective
Fixes#10968
## Solution
Pull startup schedules from a list of `ScheduleLabel`s in the same way
the update schedules are handled.
---
## Changelog
- Added `MainScheduleOrder::startup_labels` to allow the editing of the
startup schedule order.
## Migration Guide
- Added a new field to `MainScheduleOrder`, `startup_labels`, for
editing the startup schedule order.
# Objective
Keep up to date with wgpu.
## Solution
Update the wgpu version.
Currently blocked on naga_oil updating to naga 0.14 and releasing a new
version.
3d scenes (or maybe any scene with lighting?) currently don't render
anything due to
```
error: naga_oil bug, please file a report: composer failed to build a valid header: Type [2] '' is invalid
= Capability Capabilities(CUBE_ARRAY_TEXTURES) is required
```
I'm not sure what should be passed in for `wgpu::InstanceFlags`, or if we want to make the gles3minorversion configurable (might be useful for debugging?)
Currently blocked on https://github.com/bevyengine/naga_oil/pull/63, and https://github.com/gfx-rs/wgpu/issues/4569 to be fixed upstream in wgpu first.
## Known issues
Amd+windows+vulkan has issues with texture_binding_arrays (see the image [here](https://github.com/bevyengine/bevy/pull/10266#issuecomment-1819946278)), but that'll be fixed in the next wgpu/naga version, and you can just use dx12 as a workaround for now (Amd+linux mesa+vulkan texture_binding_arrays are fixed though).
---
## Changelog
Updated wgpu to 0.18, naga to 0.14.2, and naga_oil to 0.11.
- Windows desktop GL should now be less painful as it no longer requires Angle.
- You can now toggle shader validation and debug information for debug and release builds using `WgpuSettings.instance_flags` and [InstanceFlags](https://docs.rs/wgpu/0.18.0/wgpu/struct.InstanceFlags.html)
## Migration Guide
- `RenderPassDescriptor` `color_attachments` (as well as `RenderPassColorAttachment`, and `RenderPassDepthStencilAttachment`) now use `StoreOp::Store` or `StoreOp::Discard` instead of a `boolean` to declare whether or not they should be stored.
- `RenderPassDescriptor` now have `timestamp_writes` and `occlusion_query_set` fields. These can safely be set to `None`.
- `ComputePassDescriptor` now have a `timestamp_writes` field. This can be set to `None` for now.
- See the [wgpu changelog](https://github.com/gfx-rs/wgpu/blob/trunk/CHANGELOG.md#v0180-2023-10-25) for additional details
