I created this manually as Github didn't want to run CI for the
workflow-generated PR. I'm guessing we didn't hit this in previous
releases because we used bors.

# Objective
Fixes#6689.
## Solution
Add `single-threaded` as an optional non-default feature to `bevy_ecs`
and `bevy_tasks` that:
- disable the `ParallelExecutor` as a default runner
- disables the multi-threaded `TaskPool`
- internally replace `QueryParIter::for_each` calls with
`Query::for_each`.
Removed the `Mutex` and `Arc` usage in the single-threaded task pool.
## Future Work/TODO
Create type aliases for `Mutex`, `Arc` that change to single-threaaded
equivalents where possible.
---
## Changelog
Added: Optional default feature `multi-theaded` to that enables
multithreaded parallelism in the engine. Disabling it disables all
multithreading in exchange for higher single threaded performance. Does
nothing on WASM targets.

# Objective
Add support for the [Netpbm](https://en.wikipedia.org/wiki/Netpbm) image
formats, behind a `pnm` feature flag.
My personal use case for this was robotics applications, with `pgm`
being a popular format used in the field to represent world maps in
robots.
I chose the formats and feature name by checking the logic in
[image.rs](a35ed552fa/crates/bevy_render/src/texture/image.rs (L76))
## Solution
Quite straightforward, the `pnm` feature flag already exists in the
`image` crate so it's just creating and exposing a `pnm` feature flag in
the root `Cargo.toml` and forwarding it through `bevy_internal` and
`bevy_render` all the way to the `image` crate.
---
## Changelog
### Added
`pnm` feature to add support for `pam`, `pbm`, `pgm` and `ppm` image
formats.

# Objective
- I want to take screenshots of examples in CI to help with validation
of changes
## Solution
- Can override how much time is updated per frame
- Can specify on which frame to take a screenshots
- Save screenshots in CI
I reused the `TimeUpdateStrategy::ManualDuration` to be able to set the
time update strategy to a fixed duration every frame. Its previous
meaning didn't make much sense to me. This change makes it possible to
have screenshots that are exactly the same across runs.
If this gets merged, I'll add visual comparison of screenshots between
runs to ensure nothing gets broken
## Migration Guide
* `TimeUpdateStrategy::ManualDuration` meaning has changed. Instead of
setting time to `Instant::now()` plus the given duration, it sets time
to last update plus the given duration.
# Objective
- Reduce compilation time
## Solution
- Make `spirv` and `glsl` shader format support optional. They are not
needed for Bevy shaders.
- on my mac (where shaders are compiled to `msl`), this reduces the
total build time by 2 to 5 seconds, improvement should be even better
with less cores
There is a big reduction in compile time for `naga`, and small
improvements on `wgpu` and `bevy_render`

---
## Migration Guide
- If you want to use shaders in `spirv`, enable the
`shader_format_spirv` feature
- If you want to use shaders in `glsl`, enable the `shader_format_glsl`
feature
# Objective
- Have a default font
## Solution
- Add a font based on FiraMono containing only ASCII characters and use
it as the default font
- It is behind a feature `default_font` enabled by default
- I also updated examples to use it, but not UI examples to still show
how to use a custom font
---
## Changelog
* If you display text without using the default handle provided by
`TextStyle`, the text will be displayed
# Objective
bevy-scene does not have a reason to depend on bevy-render except to
include the `Visibility` and `ComputedVisibility` components. Including
that in the dependency chain is unnecessary for people not using
`bevy_render`.
Also fixed a problem where compilation fails when the `serialize`
feature was not enabled.
## Solution
This was added in #5335 to address some of the problems caused by #5310.
Imo the user just always have to remember to include `VisibilityBundle`
when they spawn `SceneBundle` or `DynamicSceneBundle`, but that will be
a breaking change. This PR makes `bevy_render` an optional dependency of
`bevy_scene` instead to respect the existing behavior.
# Objective
- Allow the use of the "glam _assert" feature to help catch runtime
errors and validate the arguments passed to glam.
e.g.
```rs
// Will panic if self is zero length when glam_assert is enabled.
pub fn normalize(self) -> Self {
let normalized = self.mul(self.length_recip());
glam_assert!(normalized.is_finite());
normalized
}
```
## Solution
- Re-export the optional feature glam_assert
---
## Changelog
Added: Optional feature "glam_assert"
# Objective
WebP is a modern image format developed by Google that offers a
significant reduction in file size compared to other image formats such
as PNG and JPEG, while still maintaining good image quality. This makes
it particularly useful for games with large numbers of images, such as
those with high-quality textures or detailed sprites, where file size
and loading times can have a significant impact on performance.
By adding support for WebP images in Bevy, game developers using this
engine can now take advantage of this modern image format and reduce the
memory usage and loading times of their games. This improvement can
ultimately result in a better gaming experience for players.
In summary, the objective of adding WebP image format support in Bevy is
to enable game developers to use a modern image format that provides
better compression rates and smaller file sizes, resulting in faster
loading times and reduced memory usage for their games.
## Solution
To add support for WebP images in Bevy, this pull request leverages the
existing `image` crate support for WebP. This implementation is easily
integrated into the existing Bevy asset-loading system. To maintain
compatibility with existing Bevy projects, WebP image support is
disabled by default, and developers can enable it by adding a feature
flag to their project's `Cargo.toml` file. With this feature, Bevy
becomes even more versatile for game developers and provides a valuable
addition to the game engine.
---
## Changelog
- Added support for WebP image format in Bevy game engine
## Migration Guide
To enable WebP image support in your Bevy project, add the following
line to your project's Cargo.toml file:
```toml
bevy = { version = "*", features = ["webp"]}
```
# Objective
Bevy with
```
default-features = false
features = [
"trace_tracy"
]
```
will fail due to `error: The platform you're compiling for is not
supported by winit`
## Solution
- Make bevy_winit/trace optional in trace feature
# Objective
Add a convenient immediate mode drawing API for visual debugging.
Fixes#5619
Alternative to #1625
Partial alternative to #5734
Based off https://github.com/Toqozz/bevy_debug_lines with some changes:
* Simultaneous support for 2D and 3D.
* Methods for basic shapes; circles, spheres, rectangles, boxes, etc.
* 2D methods.
* Removed durations. Seemed niche, and can be handled by users.
<details>
<summary>Performance</summary>

## Changelog
* Added `GizmoPlugin`
* Added `Gizmos` system parameter for drawing lines and wireshapes.
### TODO
- [ ] Update changelog
- [x] Update performance numbers
- [x] Add credit to PR description
### Future work
- Cache rendering primitives instead of constructing them out of line
segments each frame.
- Support for drawing solid meshes
- Interactions. (See
[bevy_mod_gizmos](https://github.com/LiamGallagher737/bevy_mod_gizmos))
- Fancier line drawing. (See
[bevy_polyline](https://github.com/ForesightMiningSoftwareCorporation/bevy_polyline))
- Support for `RenderLayers`
- Display gizmos for a certain duration. Currently everything displays
for one frame (ie. immediate mode)
- Changing settings per drawn item like drawing on top or drawing to
different `RenderLayers`

# Objective
UIs created for Bevy cannot currently be made accessible. This PR aims to address that.
## Solution
Integrate AccessKit as a dependency, adding accessibility support to existing bevy_ui widgets.
## Changelog
### Added
* Integrate with and expose [AccessKit](https://accesskit.dev) for platform accessibility.
* Add `Label` for marking text specifically as a label for UI controls.
# Objective
- `bevy_text` used to be "optional". the feature could be disabled, which meant that the systems were not added but `bevy_text` was still compiled because of a hard dependency in `bevy_ui`
- Running something without `bevy_text` enabled and with `bevy_ui` enabled now crashes:
```
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', /bevy/crates/bevy_ecs/src/schedule/schedule.rs:1147:34
```
- This is because `bevy_ui` declares some of its systems in ambiguity sets with systems from `bevy_text`, which were not added if `bevy_text` is disabled
## Solution
- Make `bevy_text` completely optional
## Migration Guide
- feature `bevy_text` now completely removes `bevy_text` from the dependencies when not enabled. Enable feature `bevy_text` if you use Bevy to render text
# Objective
Splits tone mapping from https://github.com/bevyengine/bevy/pull/6677 into a separate PR.
Address https://github.com/bevyengine/bevy/issues/2264.
Adds tone mapping options:
- None: Bypasses tonemapping for instances where users want colors output to match those set.
- Reinhard
- Reinhard Luminance: Bevy's exiting tonemapping
- [ACES](https://github.com/TheRealMJP/BakingLab/blob/master/BakingLab/ACES.hlsl) (Fitted version, based on the same implementation that Godot 4 uses) see https://github.com/bevyengine/bevy/issues/2264
- [AgX](https://github.com/sobotka/AgX)
- SomewhatBoringDisplayTransform
- TonyMcMapface
- Blender Filmic
This PR also adds support for EXR images so they can be used to compare tonemapping options with reference images.
## Migration Guide
- Tonemapping is now an enum with NONE and the various tonemappers.
- The DebandDither is now a separate component.

Profiles show that in extremely hot loops, like the draw loops in the renderer, invoking the trace! macro has noticeable overhead, even if the trace log level is not enabled.
Solve this by introduce a 'wrapper' detailed_trace macro around trace, that wraps the trace! log statement in a trivially false if statement unless a cargo feature is enabled
# Objective
- Eliminate significant overhead observed with trace-level logging in render hot loops, even when trace log level is not enabled.
- This is an alternative solution to the one proposed in #7223
## Solution
- Introduce a wrapper around the `trace!` macro called `detailed_trace!`. This macro wraps the `trace!` macro with an if statement that is conditional on a new cargo feature, `detailed_trace`. When the feature is not enabled (the default), then the if statement is trivially false and should be optimized away at compile time.
- Convert the observed hot occurrences of trace logging in `TrackedRenderPass` with this new macro.
Testing the results of
```
cargo run --profile stress-test --features bevy/trace_tracy --example many_cubes -- spheres
```
shows significant improvement of the `main_opaque_pass_3d` of the renderer, a median time decrease from 6.0ms to 3.5ms.
---
## Changelog
- For performance reasons, some detailed renderer trace logs now require the use of cargo feature `detailed_trace` in addition to setting the log level to `TRACE` in order to be shown.
## Migration Guide
- Some detailed bevy trace events now require the use of the cargo feature `detailed_trace` in addition to enabling `TRACE` level logging to view. Should you wish to see these logs, please compile your code with the bevy feature `detailed_trace`. Currently, the only logs that are affected are the renderer logs pertaining to `TrackedRenderPass` functions
# Objective
- Merge the examples on iOS and Android
- Make sure they both work from the same code
## Solution
- don't create window when not in an active state (from #6830)
- exit on suspend on Android (from #6830)
- automatically enable dependency feature of bevy_audio on android so that it works out of the box
- don't inverse y position of touch events
- reuse the same example for both Android and iOS
Fixes#4616Fixes#4103Fixes#3648Fixes#3458Fixes#3249Fixes#86
# Objective
- Update winit to 0.28
## Solution
- Small API change
- A security advisory has been added for a unmaintained crate used by a dependency of winit build script for wayland
I didn't do anything for Android support in this PR though it should be fixable, it should be done in a separate one, maybe https://github.com/bevyengine/bevy/pull/6830
---
## Changelog
- `window.always_on_top` has been removed, you can now use `window.window_level`
## Migration Guide
before:
```rust
app.new()
.add_plugins(DefaultPlugins.set(WindowPlugin {
primary_window: Some(Window {
always_on_top: true,
..default()
}),
..default()
}));
```
after:
```rust
app.new()
.add_plugins(DefaultPlugins.set(WindowPlugin {
primary_window: Some(Window {
window_level: bevy:🪟:WindowLevel::AlwaysOnTop,
..default()
}),
..default()
}));
```
# Problemo
Some code in #5911 and #5454 does not compile with dynamic linking enabled.
The code is behind a feature gate to prevent dynamically linked builds from breaking, but it's not quite set up correctly.
## Solution
Forward the `dynamic` feature flag to the `bevy_diagnostic` crate and gate the code behind it.

# Objective
Fixes#6030, making ``serde`` optional.
## Solution
This was solved by making a ``serialize`` feature that can activate ``serde``, which is now optional.
When ``serialize`` is deactivated, the ``Plugin`` implementation for ``ScenePlugin`` does nothing.
Co-authored-by: Linus Käll <linus.kall.business@gmail.com>
# Objective
`bevy_core` is missing a feature corresponding to the `serialize` feature on the `bevy` crate. Similar to #6378 and https://github.com/bevyengine/bevy/pull/6379 to serialize `Name` easily.
## Solution
Add this feature and hand-written serialization for `Name` (to avoid storing `hash` field).
---
## Changelog
### Added
* `Serialize` and `Deserialize` derives for `Name` under `serialize` feature.
# Objective
Fixes#6378
`bevy_transform` is missing a feature corresponding to the `serialize` feature on the `bevy` crate.
## Solution
Adds a `serialize` feature to `bevy_transform`.
Derives `serde::Serialize` and `Deserialize` when feature is enabled.
# Objective
- Update `wgpu` to 0.14.0, `naga` to `0.10.0`, `winit` to 0.27.4, `raw-window-handle` to 0.5.0, `ndk` to 0.7.
## Solution
---
## Changelog
### Changed
- Changed `RawWindowHandleWrapper` to `RawHandleWrapper` which wraps both `RawWindowHandle` and `RawDisplayHandle`, which satisfies the `impl HasRawWindowHandle and HasRawDisplayHandle` that `wgpu` 0.14.0 requires.
- Changed `bevy_window::WindowDescriptor`'s `cursor_locked` to `cursor_grab_mode`, change its type from `bool` to `bevy_window::CursorGrabMode`.
## Migration Guide
- Adjust usage of `bevy_window::WindowDescriptor`'s `cursor_locked` to `cursor_grab_mode`, and adjust its type from `bool` to `bevy_window::CursorGrabMode`.
# Objective
Fixes#6244
## Solution
Uses derive to implement `Serialize` and `Deserialize` for `Timer` and `Stopwatch`
### Things to consider
- Should fields such as `finished` and `times_finished_this_tick` in `Timer` be serialized?
- Does `Countdown` and `PrintOnCompletionTimer` need to be serialized and deserialized?
## Changelog
Added `Serialize` and `Deserialize` implementations to `Timer` and `Stopwatch`, `Countdown`.
# Objective
Add traits to events in `bevy_input` and `bevy_windows`: `Copy`, `Serialize`/`Deserialize`, `PartialEq`, and `Eq`, as requested in https://github.com/bevyengine/bevy/issues/6022, https://github.com/bevyengine/bevy/issues/6023, https://github.com/bevyengine/bevy/issues/6024.
## Solution
Added the traits to events in `bevy_input` and `bevy_windows`. Added dependency of `serde` in `Cargo.toml` of `bevy_input`.
## Migration Guide
If one has been `.clone()`'ing `bevy_input` events, Clippy will now complain about that. Just remove `.clone()` to solve.
## Other Notes
Some events in `bevy_input` had `f32` fields, so `Eq` trait was not derived for them.
Some events in `bevy_windows` had `String` fields, so `Copy` trait was not derived for them.

# Objective
- Even though it's marked as optional, it is no longer possible to not depend on `bevy_render` as it's a dependency of `bevy_scene`
## Solution
- Make `bevy_scene` optional
- For the minimalist among us, also make `bevy_asset` optional
# Objective
- Optional dependencies were enabled by some features as a side effect. for example, enabling the `webgl` feature enables the `bevy_pbr` optional dependency
## Solution
- Use the syntax introduced in rust 1.60 to specify weak dependency features: https://blog.rust-lang.org/2022/04/07/Rust-1.60.0.html#new-syntax-for-cargo-features
> Weak dependency features tackle the second issue where the `"optional-dependency/feature-name"` syntax would always enable `optional-dependency`. However, often you want to enable the feature on the optional dependency only if some other feature has enabled the optional dependency. Starting in 1.60, you can add a ? as in `"package-name?/feature-name"` which will only enable the given feature if something else has enabled the optional dependency.
# Objective
Fix#4958
There was 4 issues:
- this is not true in WASM and on macOS: f28b921209/examples/3d/split_screen.rs (L90)
- ~~I made sure the system was running at least once~~
- I'm sending the event on window creation
- in webgl, setting a viewport has impacts on other render passes
- only in webgl and when there is a custom viewport, I added a render pass without a custom viewport
- shaderdef NO_ARRAY_TEXTURES_SUPPORT was not used by the 2d pipeline
- webgl feature was used but not declared in bevy_sprite, I added it to the Cargo.toml
- shaderdef NO_STORAGE_BUFFERS_SUPPORT was not used by the 2d pipeline
- I added it based on the BufferBindingType
The last commit changes the two last fixes to add the shaderdefs in the shader cache directly instead of needing to do it in each pipeline

# Objective
- Upgrading ndk-glue (our Android interop layer) desynchronized us from winit
- This further broke Android builds, see #4905 (oops...)
- Reverting to 0.5 should help with this, until the new `winit` version releases
- Fixes#4774 and closes#4529
# Objective
Reduce the catch-all grab-bag of functionality in bevy_core by minimally splitting off time functionality into bevy_time. Functionality like that provided by #3002 would increase the complexity of bevy_time, so this is a good candidate for pulling into its own unit.
A step in addressing #2931 and splitting bevy_core into more specific locations.
## Solution
Pull the time module of bevy_core into a new crate, bevy_time.
# Migration guide
- Time related types (e.g. `Time`, `Timer`, `Stopwatch`, `FixedTimestep`, etc.) should be imported from `bevy::time::*` rather than `bevy::core::*`.
- If you were adding `CorePlugin` manually, you'll also want to add `TimePlugin` from `bevy::time`.
- The `bevy::core::CorePlugin::Time` system label is replaced with `bevy::time::TimeSystem`.

# Objective
The pointer types introduced in #3001 are useful not just in `bevy_ecs`, but also in crates like `bevy_reflect` (#4475) or even outside of bevy.
## Solution
Extract `Ptr<'a>`, `PtrMut<'a>`, `OwnedPtr<'a>`, `ThinSlicePtr<'a, T>` and `UnsafeCellDeref` from `bevy_ecs::ptr` into `bevy_ptr`.
**Note:** `bevy_ecs` still reexports the `bevy_ptr` as `bevy_ecs::ptr` so that crates like `bevy_transform` can use the `Bundle` derive without needing to depend on `bevy_ptr` themselves.
# Objective
- in #3851, a feature for tracing was added to bevy_transform
- usage of that feature was moved to bevy_hierarchy, but the feature was not updated
## Solution
- add the feature to bevy_hierarchy, remove it from bevy_transform
# Objective
- Provide more information when despawning an entity
## Solution
- Add a debug log when despawning an entity
- Add spans to the recursive ways of despawning an entity
```sh
RUST_LOG=debug cargo run --example panic --features trace
# RUST_LOG=debug needed to show debug logs from bevy_ecs
# --features trace needed to have the extra spans
...
DEBUG bevy_app:frame:stage{name=Update}:system_commands{name="panic::despawn_parent"}:command{name="DespawnRecursive" entity=0v0}: bevy_ecs::world: Despawning entity 1v0
DEBUG bevy_app:frame:stage{name=Update}:system_commands{name="panic::despawn_parent"}:command{name="DespawnRecursive" entity=0v0}: bevy_ecs::world: Despawning entity 0v0
```
Currently `tracy` interprets the entire trace as one frame because the marker for frames isn't being recorded.
~~When an event with `tracy.trace_marker=true` is recorded, `tracing-tracy` will mark the frame as finished:
<aa0b96b2ae/tracing-tracy/src/lib.rs (L240)>~~
~~Unfortunately this leads to~~
```rs
INFO bevy_app:frame: bevy_app::app: finished frame tracy.frame_mark=true
```
~~being printed every frame (we can't use DEBUG because bevy_log sets `max_release_level_info`.~~
Instead of emitting an event that gets logged every frame, we can depend on tracy-client itself and call `finish_continuous_frame!();`
