# Objective
- Changes the default clear color to match the code block color on
Bevy's website.
## Solution
- Changed the clear color, updated text in examples to ensure adequate
contrast. Inconsistent usage of white text color set to use the default
color instead, which is already white.
- Additionally, updated the `3d_scene` example to make it look a bit
better, and use bevy's branding colors.
# Objective
Make `bevy_ui` "root" nodes more intuitive to use/style by:
- Removing the implicit flexbox styling (such as stretch alignment) that
is applied to them, and replacing it with more intuitive CSS Grid
styling (notably with stretch alignment disabled in both axes).
- Making root nodes layout independently of each other. Instead of there
being a single implicit "viewport" node that all root nodes are children
of, there is now an implicit "viewport" node *per root node*. And layout
of each tree is computed separately.
## Solution
- Remove the global implicit viewport node, and instead create an
implicit viewport node for each user-specified root node.
- Keep track of both the user-specified root nodes and the implicit
viewport nodes in a separate `Vec`.
- Use the window's size as the `available_space` parameter to
`Taffy.compute_layout` rather than setting it on the implicit viewport
node (and set the viewport to `height: 100%; width: 100%` to make this
"just work").
---
## Changelog
- Bevy UI now lays out root nodes independently of each other in
separate layout contexts.
- The implicit viewport node (which contains each user-specified root
node) is now `Display::Grid` with `align_items` and `justify_items` both
set to `Start`.
## Migration Guide
- Bevy UI now lays out root nodes independently of each other in
separate layout contexts. If you were relying on your root nodes being
able to affect each other's layouts, then you may need to wrap them in a
single root node.
- The implicit viewport node (which contains each user-specified root
node) is now `Display::Grid` with `align_items` and `justify_items` both
set to `Start`. You may need to add `height: Val::Percent(100.)` to your
root nodes if you were previously relying on being implicitly set.
# Objective
In Bevy 10.1 and before, the only way to enable text wrapping was to set
a local `Val::Px` width constraint on the text node itself.
`Val::Percent` constraints and constraints on the text node's ancestors
did nothing.
#7779 fixed those problems. But perversely displaying unwrapped text is
really difficult now, and requires users to nest each `TextBundle` in a
`NodeBundle` and apply `min_width` and `max_width` constraints. Some
constructions may even need more than one layer of nesting. I've seen
several people already who have really struggled with this when porting
their projects to main in advance of 0.11.
## Solution
Add a `NoWrap` variant to the `BreakLineOn` enum.
If `NoWrap` is set, ignore any constraints on the width for the text and
call `TextPipeline::queue_text` with a width bound of `f32::INFINITY`.
---
## Changelog
* Added a `NoWrap` variant to the `BreakLineOn` enum.
* If `NoWrap` is set, any constraints on the width for the text are
ignored and `TextPipeline::queue_text` is called with a width bound of
`f32::INFINITY`.
* Changed the `size` field of `FixedMeasure` to `pub`. This shouldn't
have been private, it was always intended to have `pub` visibility.
* Added a `with_no_wrap` method to `TextBundle`.
## Migration Guide
`bevy_text::text::BreakLineOn` has a new variant `NoWrap` that disables
text wrapping for the `Text`.
Text wrapping can also be disabled using the `with_no_wrap` method of
`TextBundle`.
# Objective
- Simplify API and make authoring styles easier
See:
https://github.com/bevyengine/bevy/issues/8540#issuecomment-1536177102
## Solution
- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by `width`, `height`, `min_width`, `min_height`, `max_width`,
`max_height`, `row_gap`, and `column_gap` properties
---
## Changelog
- Flattened `Style` properties that have a `Size` value directly into
`Style`
## Migration Guide
- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by the `width`, `height`, `min_width`, `min_height`,
`max_width`, `max_height`, `row_gap`, and `column_gap` properties. Use
the new properties instead.
