# Objective
The current 2d rendering is specialized to render sprites, we need a generic way to render 2d items, using meshes and materials like we have for 3d.
## Solution
I cloned a good part of `bevy_pbr` into `bevy_sprite/src/mesh2d`, removed lighting and pbr itself, adapted it to 2d rendering, added a `ColorMaterial`, and modified the sprite rendering to break batches around 2d meshes.
~~The PR is a bit crude; I tried to change as little as I could in both the parts copied from 3d and the current sprite rendering to make reviewing easier. In the future, I expect we could make the sprite rendering a normal 2d material, cleanly integrated with the rest.~~ _edit: see <https://github.com/bevyengine/bevy/pull/3460#issuecomment-1003605194>_
## Remaining work
- ~~don't require mesh normals~~ _out of scope_
- ~~add an example~~ _done_
- support 2d meshes & materials in the UI?
- bikeshed names (I didn't think hard about naming, please check if it's fine)
## Remaining questions
- ~~should we add a depth buffer to 2d now that there are 2d meshes?~~ _let's revisit that when we have an opaque render phase_
- ~~should we add MSAA support to the sprites, or remove it from the 2d meshes?~~ _I added MSAA to sprites since it's really needed for 2d meshes_
- ~~how to customize vertex attributes?~~ _#3120_

# Objective
Updated the docs for bevy_ui as requested by #3492
## Solution
I have documented the parts I understand. anchors.rs is not in use and should be removed, thus I haven't documented that, and some of the more renderer-heavy code is beyond me and needs input from either cart or someone familiar with bevy rendering

# Objective
- Using plain exponential depth slicing for perspective projection cameras results in unnecessarily many slices very close together close to the camera. If the camera is then moved close to a collection of point lights, they will likely exhaust the available uniform buffer space for the lists of which lights affect which clusters.
## Solution
- A simple solution to this is to use a different near plane value for the depth slicing and set it to where the first slice's far plane should be. The default value is 5 and works well. This results in the configured number of depth slices, maintains the exponential slicing beyond the initial slice, and no slices are too small such that they cause problems that are sensitive to the view position.
# Objective
- Fix the case mentioned in https://github.com/bevyengine/bevy/pull/2725#issuecomment-1007014024.
- On a machine with 4 cores, so 1 thread for assets, loading a gltf with only one textures hangs all asset loading
## Solution
- Do not use the task pool when there is only one texture to load

# Objective
- More colours
## Solution
- Various changes
- Would have a video here, but don't have an easy way to record one before I go to sleep
- I intend to additionally change the distribution of the satellites, to be more uniform in space.
#3457 adds the `doc_markdown` clippy lint, which checks doc comments to make sure code identifiers are escaped with backticks. This causes a lot of lint errors, so this is one of a number of PR's that will fix those lint errors one crate at a time.
This PR fixes lints in the `bevy_ecs` crate.
# Objective
Part of #3492
- Complete inline documentation of `bevy_audio`
## Solution
- Added inline documentation to all public parts of `bevy_audio`
- Added a few inline examples at important places
- Some renaming for clarity (e.g. `AudioLoader` and generics)
- added `#![warn(missing_docs)]` and `#![forbid(unsafe_code)]` to `bevy_audio`
I also tried adding support for the other vorbis file endings `.oga` and `.spx` to the `AudioLoader` (see `file endings` at https://tools.ietf.org/html/rfc5334#section-10.3), but the `rodio` decoder does not seem to support those.

# Objective
- Fixes#1920.
- Users often want to know how to get the values of removed components (#1655).
- Stand-alone `bevy_ecs` behavior is very unintuitive, as `World::clear_trackers()` must be manually called.
- Fixes#2999 by extending the existing test (thanks @hymm for pointing me to it) to be clearer and check for component removal as well.
## Solution
- Better docs!
- Better tests!
# Objective
- Load names of lights from gltf

# Objective
- Allow the user to specify the priority when configuring wgpu features/limits and by default use the maximum capabilities of the chosen adapter.
## Solution
- Add a `WgpuOptionsPriority` enum with `Compatibility`, `Functionality` and `WebGL2` options.
- Add a `priority: WgpuOptionsPriority` member to `WgpuOptions`.
- When initialising the renderer, if `WgpuOptions::priority == WgpuOptionsPriority::Functionality`, query the adapter for the available features and limits, use them when creating a device, and update `WgpuOptions` with those values. If `Compatibility` use the behaviour as before this PR. If `WebGL2` then use the WebGL2 downlevel limits as used when when building for wasm, for convenience of testing WebGL2 limits without having to build for wasm.
- Add an environment variable `WGPU_OPTIONS_PRIO` that takes `compatibility`, `functionality`, `webgl2`.
- Default to `WgpuOptionsPriority::Functionality`.
- Insert updated `WgpuOptions` into render app world as well. This is useful for applying the limits when rendering, such as limiting the directional light shadow map texture to 2048x2048 when using WebGL2 downlevel limits but not on wasm.
- Reduced `draw_state` logs from `debug` to `trace` and added `debug` level logs for the wgpu features and limits. Use `RUST_LOG=bevy_render=debug` to see the output.
# Objective
- For a plugin, I would like to enable `bevy_ui` without adding the complete `render` feature
## Solution
- Add a feature for `bevy_ui`

Modifies the code emitted by `derive_label` to use fully-qualified type
names (e.g. `std::boxed::Box` instead of `Box`).
# Objective
- Using unqualified types here causes errors when the proc macro is used in contexts that locally define types with conflicting names (e.g. a local definition of `Box`).
## Solution
- Fully qualify standard types emitted by the proc macro code.
# Objective
- Update CONTRIBUTING.md with the arrival of a new member who has merge rights
## Solution
- Just add them to the CONTRIBUTING.md

<blockquote>
<h2>[0.30.0] (02 Jan. 2022)</h2>
<h3>Breaking changes</h3>
<ul>
<li>The <code>Dim</code> trait is now marked as unsafe.</li>
<li>The <code>Matrix::pow</code> and <code>Matrix::pow_mut</code> methods only allow positive integer exponents now. To compute negative
exponents, the user is free to invert the matrix before calling <code>pow</code> with the exponent’s absolute value.</li>
</ul>
<h3>Modified</h3>
<ul>
<li>Use more concise debug impls for matrices and geometric transformation types.</li>
<li>The singular values computed by the SVD are now sorted in increasing order by default. Use <code>SVD::new_unordered</code>
instead to reproduce the older behavior without the sorting overhead.</li>
<li>The <code>UnitDualQuaternion::sclerp</code> method will no longer panic when given two equal rotations.</li>
<li>The <code>Matrix::select_rows</code> and <code>Matrix::select_columns</code> methods no longer require the matrix components to implement
the trait <code>Zero</code>.</li>
<li>The <code>Matrix::pow</code> and <code>Matrix::pow_mut</code> methods will now also work with integer matrices.</li>
</ul>
<h3>Added</h3>
<ul>
<li>Added the conversion trait <code>From<Vec<T>></code> and method <code>from_vec_storage</code> for <code>RowDVector</code>.</li>
<li>Added implementation of <code>From</code> and <code>Into</code> for converting between <code>nalgebra</code> types and types from
<code>glam 0.18</code>. These can be enabled by enabling the <code>convert-glam018</code> cargo features.</li>
<li>Added the methods <code>Matrix::product</code>, <code>::row_product</code>, <code>::row_product_tr</code>, and <code>::column_product</code> to compute the
product of the components, rows, or columns, of a single matrix or vector.</li>
<li>The <code>Default</code> trait is now implemented for most geometric types: <code>Point</code>, <code>Isometry</code>, <code>Rotation</code>, <code>Similarity</code>,
<code>Transform</code>, <code>UnitComplex</code>, and <code>UnitQuaternion</code>.</li>
<li>Added the <code>Scale</code> geometric type for representing non-uniform scaling.</li>
<li>Added <code>Cholesky::new_with_substitute</code> that will replace diagonal elements by a given constant whenever <code>Cholesky</code>
meets a non-definite-positiveness.</li>
<li>Re-added the conversion from a vector/matrix slice to a static array.</li>
<li>Added the <code>cuda</code> feature that enables the support of <a href="https://github.com/Rust-GPU/Rust-CUDA">rust-cuda</a> for using
<code>nalgebra</code> features with CUDA kernels written in Rust.</li>
<li>Added special-cases implementations for the 2x2 and 3x3 SVDs for better accuracy and performances.</li>
<li>Added the methods <code>Matrix::polar</code>, <code>Matrix::try_polar</code>, and <code>SVD::to_polar</code> to compute the polar decomposition of
a matrix, based on its SVD.</li>
<li><code>nalgebra-sparse</code>: provide constructors for unsorted but otherwise valid data using the CSR format.</li>
<li><code>nalgebra-sparse</code>: added reading MatrixMarked data files to a sparse <code>CooMatrix</code>.</li>
</ul>
<h3>Fixed</h3>
<ul>
<li>Fixed a potential unsoundness with <code>matrix.get(i)</code> and <code>matrix.get_mut(i)</code> where <code>i</code> is an <code>usize</code>, and <code>matrix</code>
is a matrix slice with non-default strides.</li>
<li>Fixed potential unsoundness with <code>vector.perp</code> where <code>vector</code> isn’t actually a 2D vector as expected.</li>
<li>Fixed linkage issue with <code>nalgebra-lapack</code>: the user of <code>nalgebra-lapack</code> no longer have to add
<code>extern crate lapack-src</code> to their <code>main.rs</code>.</li>
<li>Fixed the <code>no-std</code> build of <code>nalgebra-glm</code>.</li>
<li>Fix the <code>pow</code> and <code>pow_mut</code> functions (the result was incorrect for some exponent values).</li>
</ul>
<h2>[0.29.0]</h2>
<h3>Breaking changes</h3>
<ul>
<li>We updated to the version 0.6 of <code>simba</code>. This means that the trait bounds <code>T: na::RealField</code>, <code>na::ComplexField</code>,
<code>na::SimdRealField</code>, <code>na:SimdComplexField</code> no imply that <code>T: Copy</code> (they only imply that <code>T: Clone</code>). This may affect</li>

# Objective
- Add support for loading lights from glTF 2.0 files
## Solution
- This adds support for the KHR_punctual_lights extension which supports point, directional, and spot lights, though we don't yet support spot lights.
- Inserting light bundles when creating scenes required registering some more light bundle component types.
# Objective
- Revert #3517 as the dependency added (rust-libudev-devel) has a dependency on cargo which install the package manager version, which isn't compatible with rustup version and may break the setup of users

This PR is part of the issue #3492.
# Objective
- Clean up dead code in `bevy_core`.
- Add and update the `bevy_core` documentation to achieve a 100% documentation coverage.
- Add the #![warn(missing_docs)] lint to keep the documentation coverage for the future.
# Solution
- Remove unused `Bytes`, `FromBytes`, `Labels`, and `EntityLabels` types and associated systems.
- Made several types private that really only have use as internal types, mostly pertaining to fixed timestep execution.
- Add and update the bevy_core documentation.
- Add the #![warn(missing_docs)] lint.
# Open Questions
Should more of the internal states of `FixedTimestep` be public? Seems mostly to be an implementation detail unless someone really needs that fixed timestep state.
# Objective
- Nightly checks where disabled because of a bug in Rust
- Dependency checks are failing because of a new duplicate
## Solution
- Now that https://github.com/rust-lang/rust/pull/92175 has been merged, re-enable nightly checks
- Add the new duplicate dependency to the known list
- Removed `Inflector` dependency as it's not used anymore
Co-authored-by: François <8672791+mockersf@users.noreply.github.com>
# Objective
Docs updates.
## Solution
- Detail what `OrthographicCameraBundle::new_2d()` creates.
- Fix a few renamed parameters in comments of `TrackedRenderPass`.
- Add missing comments for viewport and debug markers.

This PR is part of the issue #3492.
# Objective
- Add and update the bevy_dylib documentation to achieve a 100% documentation coverage.
- Add the #![warn(missing_docs)] lint to keep the documentation coverage for the future.
# Solution
- Add and update the bevy_dylib documentation.
- Add the #![warn(missing_docs)] lint.
# Objective
- Using the instructions given for NixOS results in an unnecessarily long time to evaluate the shell expression due to unnecessary dependencies pulled in by `lutris`.
## Solution
- Removed `lutris` dependency.
Lutris is a GUI tool for running games on wine, I'm assuming it was pulled in by accident as it's definitely not necessary for running bevy. A hello world example, at the least, works fine without it.
Thanks for making Bevy. Recommend adding rust-libudev-devel as an additional dependence for Fedora.
# Objective
- Describe the objective or issue this PR addresses.
- If you're fixing a specific issue, say "Fixes #X".
## Solution
- Describe the solution used to achieve the objective above.
# Objective
This contributes documentation that should cover the entirety of bevy_internal as requested in #3492
## Solution
warn(missing_docs) has been activated and documentation has been added to missing parts so that no warnings appear from this setting
# Objective
- The focus areas and roadmap are very stale.
- Some of the information about how to learn or contribute to Bevy are outdated
## Solution
- Remove links to focus areas and roadmap (roadmap still exists, and will be updated post-release).
- Link to Bevy Assets, CONTRIBUTING.md and official examples.
# Objective
- After updating #2988, all the examples started crashing with
```
thread 'main' panicked at 'Plugin "bevy_render::render_component::ExtractComponentPlugin<bevy_asset::handle::Handle<bevy_pbr::pbr_material::StandardMaterial>>" was already added', crates/bevy_app/src/app.rs:831:33
```
## Solution
Plugin was added twice:
directly:
1d0d8a3397/crates/bevy_pbr/src/lib.rs (L73)
and through `MaterialPlugin`:
1d0d8a3397/crates/bevy_pbr/src/lib.rs (L72)1d0d8a3397/crates/bevy_pbr/src/material.rs (L183)
I removed the extra plugin

# Objective
Remove the `StorageType` parameter from `ComponentDescriptor::new_resource` as discussed in #3361.
- fixes#3361
## Solution
- Parameter removed.
- Basic docs added.
## Note
Left a [comment](https://github.com/bevyengine/bevy/issues/3361#issuecomment-996433346) about `SparseStorage` being the more reasonable choice.

# Objective
- `Msaa` was disabled in webgl due to a bug in wgpu
- Bug has been fixed (https://github.com/gfx-rs/wgpu/pull/2307) and backported (https://github.com/gfx-rs/wgpu/pull/2327), and updates for [`wgpu-core`](https://crates.io/crates/wgpu-core/0.12.1) and [`wgpu-hal`](https://crates.io/crates/wgpu-hal/0.12.1) have been released
## Solution
- Remove custom config for `Msaa` in webgl
- I also changed two options that were using the arch instead of the `webgl` feature. it shouldn't change much for webgl, but could help if someone wants to target wasm but not webgl2

# Objective
Resolves#3277
Currenty if we try to serialize a scene that contains a `Duration` (which is very common, since `Timer` contains one), we get an error saying:
> Type 'core::time::Duration' does not support ReflectValue serialization
## Solution
Let `Duration` implement `SerializeValue`.
