# Objective
Fixes#15306
## Solution
- Add feature gate on the module and the place where each one is used
- Declare the features and make them default
## Testing
- CI
Makes the newly merged picking usable for UI elements.
currently it both triggers the events, as well as sends them as throught
commands.trigger_targets. We should probably figure out if this is
needed for them all.
# Objective
Hooks up obserers and picking for a very simple example
## Solution
upstreamed the UI picking backend from bevy_mod_picking
## Testing
tested with the new example picking/simple_picking.rs

# Objective
When depending on the `bevy_ui` crate specifically and using the
`serialize` feature flag, the compilation fails due to `bevy_math` not
having the serialize flag enabled.
## Solution
Added the `serialize` flag to the `bevy_math` dependency when using that
flag on `bevy_ui`.
## Testing
Tested by adding `bevy_math = { version = "0.14", features =
["serialize"] }` on a small Bevy library to ensure compilation was
successful.
# Objective
- Fix issue #2611
## Solution
- Add `--generate-link-to-definition` to all the `rustdoc-args` arrays
in the `Cargo.toml`s (for docs.rs)
- Add `--generate-link-to-definition` to the `RUSTDOCFLAGS` environment
variable in the docs workflow (for dev-docs.bevyengine.org)
- Document all the workspace crates in the docs workflow (needed because
otherwise only the source code of the `bevy` package will be included,
making the argument useless)
- I think this also fixes#3662, since it fixes the bug on
dev-docs.bevyengine.org, while on docs.rs it has been fixed for a while
on their side.
---
## Changelog
- The source code viewer on docs.rs now includes links to the
definitions.
Bump version after release
This PR has been auto-generated
Co-authored-by: Bevy Auto Releaser <41898282+github-actions[bot]@users.noreply.github.com>
Co-authored-by: François Mockers <mockersf@gmail.com>
# Objective
- Fixes https://github.com/bevyengine/bevy/issues/13155
- fixes https://github.com/bevyengine/bevy/issues/13517
- Supercedes https://github.com/bevyengine/bevy/pull/13381
- Requires https://github.com/DioxusLabs/taffy/pull/661
## Solution
- Taffy has been updated to:
- Apply size styles to absolutely positioned children
- Pass the node's `Style` through to the measure function
- Bevy's image measure function has been updated to make use of this
style information
## Notes
- This is currently using a git version of Taffy. If this is tested as
fixing the issue then we can turn that into a Taffy 0.5 release (this
would be the only change between Taffy 0.4 and Taffy 0.5 so upgrading is
not expected to be an issue)
- This implementation may not be completely correct. I would have
preferred to extend Taffy's gentest infrastructure to handle images and
used that to nail down the correct behaviour. But I don't have time for
that atm so we'll have to iterate on this in future. This PR at least
puts that under Bevy's control.
## Testing
- I manually tested the game_menu_example (from
https://github.com/bevyengine/bevy/issues/13155)
- More testing is probably merited
---
## Changelog
No changelog should be required as it fixes a regression on `main` that
was not present in bevy 0.13. The changelog for "Taffy upgrade" may want
to be changed from 0.4 to 0.5 if this change gets merged.

# Objective
- Enables support for `Display::Block`
- Enables support for `Overflow::Hidden`
- Allows for cleaner integration with text, image and other content
layout.
- Unblocks https://github.com/bevyengine/bevy/pull/8104
- Unlocks the possibility of Bevy creating a custom layout tree over
which Taffy operates.
- Enables #8808 / #10193 to remove a Mutex around the font system.
## Todo
- [x] ~Fix rendering of text/images to account for padding/border on
nodes (should size/position to content box rather than border box)~ In
order get this into a mergeable state this PR instead zeroes out
padding/border when syncing leaf node styles into Taffy to preserve the
existing behaviour. https://github.com/bevyengine/bevy/issues/6879 can
be fixed in a followup PR.
## Solution
- Update the version of Taffy
- Update code to work with the new version
Note: Taffy 0.4 has not yet been released. This PR is being created in
advance of the release to ensure that there are no blockers to upgrading
once the release occurs.
---
## Changelog
- Bevy now supports the `Display::Block` and `Overflow::Hidden` styles.
# 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
# Objective
Make bevy_utils less of a compilation bottleneck. Tackle #11478.
## Solution
* Move all of the directly reexported dependencies and move them to
where they're actually used.
* Remove the UUID utilities that have gone unused since `TypePath` took
over for `TypeUuid`.
* There was also a extraneous bytemuck dependency on `bevy_core` that
has not been used for a long time (since `encase` became the primary way
to prepare GPU buffers).
* Remove the `all_tuples` macro reexport from bevy_ecs since it's
accessible from `bevy_utils`.
---
## Changelog
Removed: Many of the reexports from bevy_utils (petgraph, uuid, nonmax,
smallvec, and thiserror).
Removed: bevy_core's reexports of bytemuck.
## Migration Guide
bevy_utils' reexports of petgraph, uuid, nonmax, smallvec, and thiserror
have been removed.
bevy_core' reexports of bytemuck's types has been removed.
Add them as dependencies in your own crate instead.
# Objective
Fixes#11298. Make the use of bevy_log vs bevy_utils::tracing more
consistent.
## Solution
Replace all uses of bevy_log's logging macros with the reexport from
bevy_utils. Remove bevy_log as a dependency where it's no longer needed
anymore.
Ideally we should just be using tracing directly, but given that all of
these crates are already using bevy_utils, this likely isn't that great
of a loss right now.
# Objective
- As part of the migration process we need to a) see the end effect of
the migration on user ergonomics b) check for serious perf regressions
c) actually migrate the code
- To accomplish this, I'm going to attempt to migrate all of the
remaining user-facing usages of `LegacyColor` in one PR, being careful
to keep a clean commit history.
- Fixes#12056.
## Solution
I've chosen to use the polymorphic `Color` type as our standard
user-facing API.
- [x] Migrate `bevy_gizmos`.
- [x] Take `impl Into<Color>` in all `bevy_gizmos` APIs
- [x] Migrate sprites
- [x] Migrate UI
- [x] Migrate `ColorMaterial`
- [x] Migrate `MaterialMesh2D`
- [x] Migrate fog
- [x] Migrate lights
- [x] Migrate StandardMaterial
- [x] Migrate wireframes
- [x] Migrate clear color
- [x] Migrate text
- [x] Migrate gltf loader
- [x] Register color types for reflection
- [x] Remove `LegacyColor`
- [x] Make sure CI passes
Incidental improvements to ease migration:
- added `Color::srgba_u8`, `Color::srgba_from_array` and friends
- added `set_alpha`, `is_fully_transparent` and `is_fully_opaque` to the
`Alpha` trait
- add and immediately deprecate (lol) `Color::rgb` and friends in favor
of more explicit and consistent `Color::srgb`
- standardized on white and black for most example text colors
- added vector field traits to `LinearRgba`: ~~`Add`, `Sub`,
`AddAssign`, `SubAssign`,~~ `Mul<f32>` and `Div<f32>`. Multiplications
and divisions do not scale alpha. `Add` and `Sub` have been cut from
this PR.
- added `LinearRgba` and `Srgba` `RED/GREEN/BLUE`
- added `LinearRgba_to_f32_array` and `LinearRgba::to_u32`
## Migration Guide
Bevy's color types have changed! Wherever you used a
`bevy::render::Color`, a `bevy::color::Color` is used instead.
These are quite similar! Both are enums storing a color in a specific
color space (or to be more precise, using a specific color model).
However, each of the different color models now has its own type.
TODO...
- `Color::rgba`, `Color::rgb`, `Color::rbga_u8`, `Color::rgb_u8`,
`Color::rgb_from_array` are now `Color::srgba`, `Color::srgb`,
`Color::srgba_u8`, `Color::srgb_u8` and `Color::srgb_from_array`.
- `Color::set_a` and `Color::a` is now `Color::set_alpha` and
`Color::alpha`. These are part of the `Alpha` trait in `bevy_color`.
- `Color::is_fully_transparent` is now part of the `Alpha` trait in
`bevy_color`
- `Color::r`, `Color::set_r`, `Color::with_r` and the equivalents for
`g`, `b` `h`, `s` and `l` have been removed due to causing silent
relatively expensive conversions. Convert your `Color` into the desired
color space, perform your operations there, and then convert it back
into a polymorphic `Color` enum.
- `Color::hex` is now `Srgba::hex`. Call `.into` or construct a
`Color::Srgba` variant manually to convert it.
- `WireframeMaterial`, `ExtractedUiNode`, `ExtractedDirectionalLight`,
`ExtractedPointLight`, `ExtractedSpotLight` and `ExtractedSprite` now
store a `LinearRgba`, rather than a polymorphic `Color`
- `Color::rgb_linear` and `Color::rgba_linear` are now
`Color::linear_rgb` and `Color::linear_rgba`
- The various CSS color constants are no longer stored directly on
`Color`. Instead, they're defined in the `Srgba` color space, and
accessed via `bevy::color::palettes::css`. Call `.into()` on them to
convert them into a `Color` for quick debugging use, and consider using
the much prettier `tailwind` palette for prototyping.
- The `LIME_GREEN` color has been renamed to `LIMEGREEN` to comply with
the standard naming.
- Vector field arithmetic operations on `Color` (add, subtract, multiply
and divide by a f32) have been removed. Instead, convert your colors
into `LinearRgba` space, and perform your operations explicitly there.
This is particularly relevant when working with emissive or HDR colors,
whose color channel values are routinely outside of the ordinary 0 to 1
range.
- `Color::as_linear_rgba_f32` has been removed. Call
`LinearRgba::to_f32_array` instead, converting if needed.
- `Color::as_linear_rgba_u32` has been removed. Call
`LinearRgba::to_u32` instead, converting if needed.
- Several other color conversion methods to transform LCH or HSL colors
into float arrays or `Vec` types have been removed. Please reimplement
these externally or open a PR to re-add them if you found them
particularly useful.
- Various methods on `Color` such as `rgb` or `hsl` to convert the color
into a specific color space have been removed. Convert into
`LinearRgba`, then to the color space of your choice.
- Various implicitly-converting color value methods on `Color` such as
`r`, `g`, `b` or `h` have been removed. Please convert it into the color
space of your choice, then check these properties.
- `Color` no longer implements `AsBindGroup`. Store a `LinearRgba`
internally instead to avoid conversion costs.

# Objective
- Fixes#11119
## Solution
- Creation of the serialize feature to ui
---
## Changelog
### Changed
- Changed all the structs that implement Serialize and Deserialize to
only implement when feature is on
## Migration Guide
- If you want to use serialize and deserialize with types from bevy_ui,
you need to use the feature serialize in your TOML
```toml
[dependencies.bevy]
features = ["serialize"]
```
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
- Standardize fmt for toml files
## Solution
- Add [taplo](https://taplo.tamasfe.dev/) to CI (check for fmt and diff
for toml files), for context taplo is used by the most popular extension
in VScode [Even Better
TOML](https://marketplace.visualstudio.com/items?itemName=tamasfe.even-better-toml
- Add contribution section to explain toml fmt with taplo.
Now to pass CI you need to run `taplo fmt --option indent_string=" "` or
if you use vscode have the `Even Better TOML` extension with 4 spaces
for indent

# Objective
- Fix adding `#![allow(clippy::type_complexity)]` everywhere. like #9796
## Solution
- Use the new [lints] table that will land in 1.74
(https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#lints)
- inherit lint to the workspace, crates and examples.
```
[lints]
workspace = true
```
## Changelog
- Bump rust version to 1.74
- Enable lints table for the workspace
```toml
[workspace.lints.clippy]
type_complexity = "allow"
```
- Allow type complexity for all crates and examples
```toml
[lints]
workspace = true
```

# Objective
An easy way to create 2D grid layouts
## Solution
Enable the `grid` feature in Taffy and add new style types for defining
grids.
## Notes
- ~I'm having a bit of trouble getting `#[derive(Reflect)]` to work
properly. Help with that would be appreciated (EDIT: got it to compile
by ignoring the problematic fields, but this presumably can't be
merged).~ This is now fixed
- ~The alignment types now have a `Normal` variant because I couldn't
get reflect to work with `Option`.~ I've decided to stick with the
flattened variant, as it saves a level of wrapping when authoring
styles. But I've renamed the variants from `Normal` to `Default`.
- ~This currently exposes a simplified API on top of grid. In particular
the following is not currently supported:~
- ~Negative grid indices~ Now supported.
- ~Custom `end` values for grid placement (you can only use `start` and
`span`)~ Now supported
- ~`minmax()` track sizing functions~ minmax is now support through a
`GridTrack::minmax()` constructor
- ~`repeat()`~ repeat is now implemented as `RepeatedGridTrack`
- ~Documentation still needs to be improved.~ An initial pass over the
documentation has been completed.

# Objective
`text_system` runs before the UI layout is calculated and the size of
the text node is determined, so it cannot correctly shape the text to
fit the layout, and has no way of determining if the text needs to be
wrapped.
The function `text_constraint` attempts to determine the size of the
node from the local size constraints in the `Style` component. It can't
be made to work, you have to compute the whole layout to get the correct
size. A simple example of where this fails completely is a text node set
to stretch to fill the empty space adjacent to a node with size
constraints set to `Val::Percent(50.)`. The text node will take up half
the space, even though its size constraints are `Val::Auto`
Also because the `text_system` queries for changes to the `Style`
component, when a style value is changed that doesn't affect the node's
geometry the text is recomputed unnecessarily.
Querying on changes to `Node` is not much better. The UI layout is
changed to fit the `CalculatedSize` of the text, so the size of the node
is changed and so the text and UI layout get recalculated multiple times
from a single change to a `Text`.
Also, the `MeasureFunc` doesn't work at all, it doesn't have enough
information to fit the text correctly and makes no attempt.
Fixes#7663, #6717, #5834, #1490,
## Solution
Split the `text_system` into two functions:
* `measure_text_system` which calculates the size constraints for the
text node and runs before `UiSystem::Flex`
* `text_system` which runs after `UiSystem::Flex` and generates the
actual text.
* Fix the `MeasureFunc` calculations.

## Changelog
* Removed the previous fields from `CalculatedSize`. `CalculatedSize`
now contains a boxed `Measure`.
* Added `measurement` module to `bevy_ui`.
* Added the method `create_text_measure` to `TextPipeline`.
* Added a new system `measure_text_system` that runs before
`UiSystem::Flex` that creates a `MeasureFunc` for the text.
* Rescheduled `text_system` to run after `UiSystem::Flex`.
* Added a trait `Measure`. A `Measure` is used to compute the size of a
UI node when the size of that node is based on its content.
* Added `ImageMeasure` and `TextMeasure` which implement `Measure`.
* Added a new component `UiImageSize` which is used by
`update_image_calculated_size_system` to track image size changes.
* Added a `UiImageSize` component to `ImageBundle`.
## Migration Guide
`ImageBundle` has a new component `UiImageSize` which contains the size
of the image bundle's texture and is updated automatically by
`update_image_calculated_size_system`

# Objective
Upgrade to Taffy 0.3.3
Fixes: #7712
## Solution
Upgrade to Taffy 0.3.3 with the `grid` feature disabled.
---
## Changelog
* Changed Taffy version to 0.3.3 and disabled its `grid` feature.
* Added the `Start` and `End` variants to `AlignItems`, `AlignSelf`, `AlignContent` and `JustifyContent`.
* Added the `SpaceEvenly` variant to `AlignContent`.
* Updated `from_style` for Taffy 0.3.3.
# 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
Upgrade to Taffy 0.2
## Solution
Do it
## Changelog
Upgraded to Taffy 0.2, improving UI layout performance significantly and adding the flexbox `gap` property and `AlignContent::SpaceEvenly`.
## Notes
`many_buttons` is 8% faster! speed improvements for more highly nested UIs will be much more dramatic. Great work, Team Taffy.
# Objective
- Reverts unnecessary version increase for `thiserror` caused by the following PR. 9066d51420
- The aforementioned PR should have increased `thiserrror` version uniformly across all bevy crates. As far as I can tell it was unneccessary to bump versions
## Solution
- Revert versions to the matching version used by other bevy "crates"
```
MBP-Larry-Du.local:~/Code/bevy:$ git grep thiserror

# Objective
Adds a better interface for performing mathematical operations with UI unit `Val`. Fixes#6080.
## Solution
- Added `try_add` and `try_sub` methods to Val.
- Removed the `Add` and `AddAssign` impls for `Val` that introduced unintuitive and bug-prone behaviour.
- As a consequence of the prior, ~~changed the `Add` and `Sub` impls for the `Size` struct to take a `(Val, Val)` instead of `Vec2`~~ deleted the `Add` and `Sub` impls for the `Size` struct
- Added a `From<(Val, Val)>` impl for the `Size` struct
- Added `evaluate(size: f32)` method that converts from `Val::Percent` to `Val::Px`.
- Added `try_add_with_size` and `try_sub_with_size` methods to `Val`, which evaluate `Val::Percent` values into `Val::Px` values before adding.
---
## Migration Guide
Instead of using the + and - operators, perform calculations on `Val`s using the new `try_add` and `try_sub` methods. Multiplication and division remained unchanged. Also, when adding or subtracting from `Size`, ~~use a `Val` tuple instead of `Vec2`~~ perform the addition on `width` and `height` separately.

# Objective
DioxusLabs and Bevy have taken over maintaining what was our abandoned ui layout dependency [stretch](https://github.com/vislyhq/stretch). Dioxus' fork has had a lot of work done on it by @alice-i-cecile, @Weibye , @jkelleyrtp, @mockersf, @HackerFoo, @TimJentzsch and a dozen other contributors and now is in much better shape than stretch was. The updated crate is called taffy and is available on github [here](https://github.com/DioxusLabs/taffy) ([taffy](https://crates.io/crates/taffy) on crates.io). The goal of this PR is to replace stretch v0.3.2 with taffy v0.1.0.
## Solution
I changed the bevy_ui Cargo.toml to depend on taffy instead of stretch and fixed all the errors rustc complained about.
---
## Changelog
Changed bevy_ui layout dependency from stretch to taffy (the maintained fork of stretch).
fixes#677
## Migration Guide
The public api of taffy is different from that of stretch so please advise me on what to do here @alice-i-cecile.
# Objective
- Sometimes, people might load an asset as one type, then use it with an `Asset`s for a different type.
- See e.g. #4784.
- This is especially likely with the Gltf types, since users may not have a clear conceptual model of what types the assets will be.
- We had an instance of this ourselves, in the `scene_viewer` example
## Solution
- Make `Assets::get` require a type safe handle.
---
## Changelog
### Changed
- `Assets::<T>::get` and `Assets::<T>::get_mut` now require that the passed handles are `Handle<T>`, improving the type safety of handles.
### Added
- `HandleUntyped::typed_weak`, a helper function for creating a weak typed version of an exisitng `HandleUntyped`.
## Migration Guide
`Assets::<T>::get` and `Assets::<T>::get_mut` now require that the passed handles are `Handle<T>`, improving the type safety of handles. If you were previously passing in:
- a `HandleId`, use `&Handle::weak(id)` instead, to create a weak handle. You may have been able to store a type safe `Handle` instead.
- a `HandleUntyped`, use `&handle_untyped.typed_weak()` to create a weak handle of the specified type. This is most likely to be the useful when using [load_folder](https://docs.rs/bevy_asset/latest/bevy_asset/struct.AssetServer.html#method.load_folder)
- a `Handle<U>` of of a different type, consider whether this is the correct handle type to store. If it is (i.e. the same handle id is used for multiple different Asset types) use `Handle::weak(handle.id)` to cast to a different type.
# Objective
Reduce the catch-all grab-bag of functionality in bevy_core by moving FloatOrd to bevy_utils.
A step in addressing #2931 and splitting bevy_core into more specific locations.
## Solution
Move FloatOrd into bevy_utils. Fix the compile errors.
As a result, bevy_core_pipeline, bevy_pbr, bevy_sprite, bevy_text, and bevy_ui no longer depend on bevy_core (they were only using it for `FloatOrd` previously).
# Objective
- Hierarchy tools are not just used for `Transform`: they are also used for scenes.
- In the future there's interest in using them for other features, such as visiibility inheritance.
- The fact that these tools are found in `bevy_transform` causes a great deal of user and developer confusion
- Fixes#2758.
## Solution
- Split `bevy_transform` into two!
- Make everything work again.
Note that this is a very tightly scoped PR: I *know* there are code quality and docs issues that existed in bevy_transform that I've just moved around. We should fix those in a seperate PR and try to merge this ASAP to reduce the bitrot involved in splitting an entire crate.
## Frustrations
The API around `GlobalTransform` is a mess: we have massive code and docs duplication, no link between the two types and no clear way to extend this to other forms of inheritance.
In the medium-term, I feel pretty strongly that `GlobalTransform` should be replaced by something like `Inherited<Transform>`, which lives in `bevy_hierarchy`:
- avoids code duplication
- makes the inheritance pattern extensible
- links the types at the type-level
- allows us to remove all references to inheritance from `bevy_transform`, making it more useful as a standalone crate and cleaning up its docs
## Additional context
- double-blessed by @cart in https://github.com/bevyengine/bevy/issues/4141#issuecomment-1063592414 and https://github.com/bevyengine/bevy/issues/2758#issuecomment-913810963
- preparation for more advanced / cleaner hierarchy tools: go read https://github.com/bevyengine/rfcs/pull/53 !
- originally attempted by @finegeometer in #2789. It was a great idea, just needed more discussion!

# Objective
- Our crevice is still called "crevice", which we can't use for a release
- Users would need to use our "crevice" directly to be able to use the derive macro
## Solution
- Rename crevice to bevy_crevice, and crevice-derive to bevy-crevice-derive
- Re-export it from bevy_render, and use it from bevy_render everywhere
- Fix derive macro to work either from bevy_render, from bevy_crevice, or from bevy
## Remaining
- It is currently re-exported as `bevy::render::bevy_crevice`, is it the path we want?
- After a brief suggestion to Cart, I changed the version to follow Bevy version instead of crevice, do we want that?
- Crevice README.md need to be updated
- in the `Cargo.toml`, there are a few things to change. How do we want to change them? How do we keep attributions to original Crevice?

# Objective
- Only bevy_render should depend directly on wgpu
- This helps to make sure bevy_render re-exports everything needed from wgpu
## Solution
- Remove bevy_pbr, bevy_sprite and bevy_ui dependency on wgpu
