# 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
- Support WebGPU
- alternative to #5027 that doesn't need any async / await
- fixes#8315
- Surprise fix#7318
## Solution
### For async renderer initialisation
- Update the plugin lifecycle:
- app builds the plugin
- calls `plugin.build`
- registers the plugin
- app starts the event loop
- event loop waits for `ready` of all registered plugins in the same
order
- returns `true` by default
- then call all `finish` then all `cleanup` in the same order as
registered
- then execute the schedule
In the case of the renderer, to avoid anything async:
- building the renderer plugin creates a detached task that will send
back the initialised renderer through a mutex in a resource
- `ready` will wait for the renderer to be present in the resource
- `finish` will take that renderer and place it in the expected
resources by other plugins
- other plugins (that expect the renderer to be available) `finish` are
called and they are able to set up their pipelines
- `cleanup` is called, only custom one is still for pipeline rendering
### For WebGPU support
- update the `build-wasm-example` script to support passing `--api
webgpu` that will build the example with WebGPU support
- feature for webgl2 was always enabled when building for wasm. it's now
in the default feature list and enabled on all platforms, so check for
this feature must also check that the target_arch is `wasm32`
---
## Migration Guide
- `Plugin::setup` has been renamed `Plugin::cleanup`
- `Plugin::finish` has been added, and plugins adding pipelines should
do it in this function instead of `Plugin::build`
```rust
// Before
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>()
.init_resource::<OtherRenderResource>();
}
}
// After
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<OtherRenderResource>();
}
fn finish(&self, app: &mut App) {
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>();
}
}
```
# 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`

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
- 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
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.

### 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`

# 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
- Fixes#1800, fixes#6984
- Alternative to #7196
- Ensure feature list is always up to date and that all are documented
- Help discovery of features
## Solution
- Use a template to update the cargo feature list
- Use the comment just above the feature declaration as the description
- Add the checks to CI
- Add the features to the base crate doc
Adds documentation for setting up bevy on Alpine Linux and its derivatives.
It contains instructions on installing the required packages and also fixing runtime errors.
# Objective
I found several words in code and docs are incorrect. This should be fixed.
## Solution
- Fix several minor typos

Bevy People should be considered the source of truth for Bevy Organization roles. This replaces inline lists of maintainers and SMEs with links to Bevy People.
We are in the process of rolling out a new Bevy Organization role! (Subject Matter Expert)
This adds a new "The Bevy Organization" document and links to it from CONTRIBUTING.md. This doc describes how the Bevy Organization will work going forward. It outlines the functionality of each role, as well as the expectations we have for them. The previously existing roles (Project Lead, Maintainer) still work the same way, but their definition and scope have been made much clearer.
Tomorrow we will be announcing this publicly in a blog post. This will describe the motivation and announce the first round of SMEs . But before that it makes sense to do a quick review round first.
Given the quick turnaround on this PR, this isn't the best platform to discuss changes to the SME system (or its validity). After you have read the announcement tomorrow, feel free to start discussions wherever is preferable to you (this repo, discord, etc). So for now, please just review for clarity / typos / phrasing / missed info / etc.

# Objective
`xlibsWrapper` is being deprecated: https://github.com/NixOS/nixpkgs/issues/194054, this pr removes the deprecated xlibsWrapper and makes a couple more improvements
## Solution
- rename NixOS to Nix since this is not specific to NixOS
- remove usage of `xlibsWrapper`
- add instructions for nix flakes with `nix develop`
- add example of a packaged bevy program in nixpkgs
- minor cosmetic/grammatical changes
Add a section about install `vulkan-loader` on Gentoo.
# Objective
- Clarify the dependency about install on Gentoo with NVIDIA GPU and using a proprietary driver.
## Solution
- Emerge `vulkan-loader` to help Bevy to find the correct ICD.
# Objective
Links to `cargo-flamegraph`'s repo point to a [fork](https://github.com/killercup/cargo-flamegraph), not the actual upstream repo. We should point to the source of truth instead of a fork that hasn't been updated since 2019.
## Solution
Change links to point to the upstream repo at [flamegraph-rs/flamegraph](https://github.com/flamegraph-rs/flamegraph).
When running Bevy on Gentoo using an AMD Radeon GPU, it panics unless `amdgpu-pro-vulkan` has been installed (and it took quite a bit of experimentation to find this information). This PR adds a mention of this to the linux dependencies documentation.
for nix build, pkgconfig has been renamed to pkg-config. Very small fix :>
# 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.

> This section is optional. If this was a trivial fix, or has no externally-visible impact, you can delete this section.
- What changed as a result of this PR?
- If applicable, organize changes under "Added", "Changed", or "Fixed" sub-headings
- Stick to one or two sentences. If more detail is needed for a particular change, consider adding it to the "Solution" section
- If you can't summarize the work, your change may be unreasonably large / unrelated. Consider splitting your PR to make it easier to review and merge!
## Migration Guide
> This section is optional. If there are no breaking changes, you can delete this section.
- If this PR is a breaking change (relative to the last release of Bevy), describe how a user might need to migrate their code to support these changes
- Simply adding new functionality is not a breaking change.
- Fixing behavior that was definitely a bug, rather than a questionable design choice is not a breaking change.
# 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
- Document how to do profiling with Tracy
# Solution
- The documentation of setting `RUST_LOG=info` in order to capture `wgpu` spans depends on https://github.com/bevyengine/bevy/pull/5182
# Objective
`nix-shell` reported: ```error: 'x11' has been renamed to/replaced by 'xlibsWrapper'```.
## Solution
Replacing `x11` with `xlibsWrapper` in the Nix section of linux_dependencies.md fixes the problem on my system, and bevy projects build fine.
Change _LICENSE-APACHE_ and _LICENSE-MIT_ file location
Delete _LICENSE_
You can make the license in about on bevy's GitHub page display as **Apache-2.0, MIT licenses found** instead of **View license**
# Objective
- Guide people to the right discord channel to post about their new plugin. #showcase was split into multiple channels.
## Solution
- recommend posting in #crates
# Objective
While playing with the code, I found some problems in the recently merged version-bumping workflow:
- Most importantly, now that we are using `0.8.0-dev` in development, the workflow will try to bump it to `0.9.0` 😭
- The crate filter is outdated now that we have more crates in `tools`.
- We are using `bevy@users.noreply.github.com`, but according to [Github help](https://docs.github.com/en/account-and-profile/setting-up-and-managing-your-personal-account-on-github/managing-email-preferences/setting-your-commit-email-address#about-commit-email-addresses), that email address means "old no-reply email format for the user `bevy`". It is currently not associated with any account, but I feel this is still not appropriate here.
## Solution
- Create a new workflow, `Post-release version bump`, that should be run after a release and bumps version from `0.X.0` to `0.X+1.0-dev`. Unfortunately, cargo-release doesn't have a builtin way to do this, so we need to parse and increment the version manually.
- Add the new crates in `tools` to exclusion list. Also removes the dependency version specifier from `bevy_ecs_compile_fail_tests`. It is not in the workspace so the dependency version will not get automatically updated by cargo-release.
- Change the author email to `41898282+github-actions[bot]@users.noreply.github.com`. According to the discussion [here](https://github.com/actions/checkout/issues/13#issuecomment-724415212) and [here](https://github.community/t/github-actions-bot-email-address/17204/6), this is the email address associated with the github-actions bot account.
- Also add the workflows to our release checklist.
See infmagic2047#5 and infmagic2047#6 for examples of release and post-release PRs.
Tracing added support for "inline span entering", which cuts down on a lot of complexity:
```rust
let span = info_span!("my_span").entered();
```
This adapts our code to use this pattern where possible, and updates our docs to recommend it.
This produces equivalent tracing behavior. Here is a side by side profile of "before" and "after" these changes.
# Objective
- Support compressed textures including 'universal' formats (ETC1S, UASTC) and transcoding of them to
- Support `.dds`, `.ktx2`, and `.basis` files
## Solution
- Fixes https://github.com/bevyengine/bevy/issues/3608 Look there for more details.
- Note that the functionality is all enabled through non-default features. If it is desirable to enable some by default, I can do that.
- The `basis-universal` crate, used for `.basis` file support and for transcoding, is built on bindings against a C++ library. It's not feasible to rewrite in Rust in a short amount of time. There are no Rust alternatives of which I am aware and it's specialised code. In its current state it doesn't support the wasm target, but I don't know for sure. However, it is possible to build the upstream C++ library with emscripten, so there is perhaps a way to add support for web too with some shenanigans.
- There's no support for transcoding from BasisLZ/ETC1S in KTX2 files as it was quite non-trivial to implement and didn't feel important given people could use `.basis` files for ETC1S.
Adds "hot reloading" of internal assets, which is normally not possible because they are loaded using `include_str` / direct Asset collection access.
This is accomplished via the following:
* Add a new `debug_asset_server` feature flag
* When that feature flag is enabled, create a second App with a second AssetServer that points to a configured location (by default the `crates` folder). Plugins that want to add hot reloading support for their assets can call the new `app.add_debug_asset::<T>()` and `app.init_debug_asset_loader::<T>()` functions.
* Load "internal" assets using the new `load_internal_asset` macro. By default this is identical to the current "include_str + register in asset collection" approach. But if the `debug_asset_server` feature flag is enabled, it will also load the asset dynamically in the debug asset server using the file path. It will then set up a correlation between the "debug asset" and the "actual asset" by listening for asset change events.
This is an alternative to #3673. The goal was to keep the boilerplate and features flags to a minimum for bevy plugin authors, and allow them to home their shaders near relevant code.
This is a draft because I haven't done _any_ quality control on this yet. I'll probably rename things and remove a bunch of unwraps. I just got it working and wanted to use it to start a conversation.
Fixes#3660
Features must be called with the crate, otherwise the following error is thrown:
> error: none of the selected packages contains these features: trace_chrome
# Objective
- The Linux dependencies document lacks packages for Fedora with Wayland.
## Solution
- Add instructions to install packages for running Bevy apps in Fedora with Wayland.
# Objective
The description of NixOS dependencies is extremely long and spends entire paragraphs just for simple line changes.
With this PR it should be much simpler.
## Solution
- Linking Vulkan in `build.rs` is less effective than adding it in LD_LIBRARY_PATH, so I removed the former (related to #1992);
- I put a simple comment explaining the line in the list of dependencies, instead of making entire paragraphs;
- Clang is not in an absolute path in `.cargo/config_fast_builds` anymore, so that there is no need to specify it in `docs/linux_dependencies.md` (didn't test if this breaks other distros, though I doubt it. Also, maybe it could also be done on Darwin for consistency?);
- Also added optional wayland dependencies.
A few notes:
- The x11 libraries will be linked only during the compilation phase. This means that if you use the `x11` feature without these libraries in the environment (for example because you forget to enter the nix shell before compiling), the program will still compile successfully but won't run. You'll have to `cargo clean` and recompile with the x11 libraries in the environment. I don't know if this is important enough to be added to the documentation, but it's not specified anywhere, though I don't think it's specific to NixOS;
- The wayland dependencies need to be put in LD_LIBRARY_PATH only in certain conditions (IIRC, only if using the `dynamic` feature) and the text doesn't specify it. Because putting them there doesn't increase the number of dependencies (they are already in buildInputs) or alter the performance, I doubt anyone will care;
- Should I comment out what isn't needed by default?
- ~I removed `cargo` from buildInputs. Ignoring the fact that it should be in nativeBuildInputs, having it in `shell.nix` allows to use stable Rust in case it's not in the system environment, but maybe the user wanted to use the version that was already in the system environment and will be caught by surprise. In my opinion, if someone is looking at a Bevy's documentation on NixOS, that user will either have Rust already in the system environment (eg. via rustup) or is capable to add the toolchain they want on shell.nix by themselves. This isn't exactly the place to explain how this works.~ ~EDIT: I replaced `cargo` with Rust from the [Oxalica overlay](https://github.com/oxalica/rust-overlay) in order to have the latest nightly.~ EDIT: Removed `cargo` from dependencies. See comments for details.
# 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
Co-authored-by: François <8672791+mockersf@users.noreply.github.com>
# 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.

This makes the [New Bevy Renderer](#2535) the default (and only) renderer. The new renderer isn't _quite_ ready for the final release yet, but I want as many people as possible to start testing it so we can identify bugs and address feedback prior to release.
The examples are all ported over and operational with a few exceptions:
* I removed a good portion of the examples in the `shader` folder. We still have some work to do in order to make these examples possible / ergonomic / worthwhile: #3120 and "high level shader material plugins" are the big ones. This is a temporary measure.
* Temporarily removed the multiple_windows example: doing this properly in the new renderer will require the upcoming "render targets" changes. Same goes for the render_to_texture example.
* Removed z_sort_debug: entity visibility sort info is no longer available in app logic. we could do this on the "render app" side, but i dont consider it a priority.
# Objective
- there are a few new versions for `ron`, `winit`, `ndk`, `raw-window-handle`
- `cargo-deny` is failing due to new security issues / duplicated dependencies
## Solution
- Update our dependencies
- Note all new security issues, with which of Bevy direct dependency it comes from
- Update duplicate crate list, with which of Bevy direct dependency it comes from
`notify` is not updated here as it's in #2993
# Objective
- `bevy_ecs` exposes as an optional feature `bevy_reflect`. Disabling it doesn't compile.
- `bevy_asset` exposes as an optional feature `filesystem_watcher`. Disabling it doesn't compile. It is also not possible to disable this feature from Bevy
## Solution
- Fix compilation errors when disabling the default features. Make it possible to disable the feature `filesystem_watcher` from Bevy
I just updated profiling.md (and accidentally skipped the pr process by not checking "create new branch" in the github ui). The markdown wasn't properly formatted, which broke the build.
- Requires #2997
- Removes `wasm_audio` feature as discussed in #2397
- Closes only task in #2479
Open questions:
Should we enable wasm audio by default or only when building for wasm using `cfg`?
Maybe there should be a global wasm feature for bevy?
# Objective
[Tracy](https://github.com/wolfpld/tracy) is:
> A real time, nanosecond resolution, remote telemetry, hybrid frame and sampling profiler for games and other applications.
With the `trace_tracy` feature enabled, you run your bevy app and either a headless server (`capture`) or a live, interactive profiler UI (`Tracy`), and connect that to your bevy application to then stream the metric data and events, and save it or inspect it live/offline.
Previously when I implemented the spans across systems and stages and I was trying out different profiling tools, Tracy was too unstable on macOS to use. But now, quite some months later, it is working stably with Tracy 0.7.8. You can see timelines, aggregate statistics of mean system/stage execution times, and much more. It's very useful!
## Solution
- Use the `tracing-tracy` crate which supports our tracing spans
- Expose via the non-default feature `trace_tracy` for consistency with other `trace*` features
# Objective
Expand the documentation for NixOS setups (as discussed in Discord)
## Solution
Added more info to `linux_dependencies.md` about NixOS. This is based off my own experience (as documented in [this blog post](https://blog.thomasheartman.com/posts/bevy-getting-started-on-nixos)), so I can't confirm that it'll work for everyone. However, if there are further tweaks necessary, then I think that this should nevertheless work as a good starting point and should give future users an idea of what they may need to change or update.
Feedback and tweaks are very welcome 😄
# Objective
- the plugin guidelines should be up-to-date and easy to read/understand
## Solution
* point to "Bevy Assets" instead of old "Awesome Bevy"
* restructure sections
* same order for sections and checklist
* Update examples with newest release/rev
It doesn't compile on wasm, and it's full of footguns
# Objective
- If bevy is used with default features on wasm, there's more of a chance it will compile
- Note that I haven't done a full audit - it's possible that there are other problematic crates
## Solution
- `bevy_dynamic_plugin` is no longer a default plugin
- I've also done an accidental drive by reformatting of the root `Cargo.toml`, as I have [Even Better Toml](https://github.com/tamasfe/taplo) installed.
- (Please, rustfmt do this for us)
This relicenses Bevy under the dual MIT or Apache-2.0 license. For rationale, see #2373.
* Changes the LICENSE file to describe the dual license. Moved the MIT license to docs/LICENSE-MIT. Added the Apache-2.0 license to docs/LICENSE-APACHE. I opted for this approach over dumping both license files at the root (the more common approach) for a number of reasons:
* Github links to the "first" license file (LICENSE-APACHE) in its license links (you can see this in the wgpu and rust-analyzer repos). People clicking these links might erroneously think that the apache license is the only option. Rust and Amethyst both use COPYRIGHT or COPYING files to solve this problem, but this creates more file noise (if you do everything at the root) and the naming feels way less intuitive.
* People have a reflex to look for a LICENSE file. By providing a single license file at the root, we make it easy for them to understand our licensing approach.
* I like keeping the root clean and noise free
* There is precedent for putting the apache and mit license text in sub folders (amethyst)
* Removed the `Copyright (c) 2020 Carter Anderson` copyright notice from the MIT license. I don't care about this attribution, it might make license compliance more difficult in some cases, and it didn't properly attribute other contributors. We shoudn't replace it with something like "Copyright (c) 2021 Bevy Contributors" because "Bevy Contributors" is not a legal entity. Instead, we just won't include the copyright line (which has precedent ... Rust also uses this approach).
* Updates crates to use the new "MIT OR Apache-2.0" license value
* Removes the old legion-transform license file from bevy_transform. bevy_transform has been its own, fully custom implementation for a long time and that license no longer applies.
* Added a License section to the main readme
* Updated our Bevy Plugin licensing guidelines.
As a follow-up we should update the website to properly describe the new license.
Closes#2373
# Objective
@TomBebb (other account being @TomBebbington ) proved unreachable for #2373, so we need to revert their changes for the relicense.
## Solution
Revert their changes. This is only linux distro docs, so it's not critical code.
If someone else wants to test `bevy` on solus to work out the set of packages independently, then we'll probably accept a PR to add these. One suggestsion would be to consider the packages required on other systems, since there is likely to be some overlap.
## Alternatives
Link to this old version in the `linux_dependencies.md` file.
This obsoletes #1111 and #2445, since @ColonisationCaptain and @temhotaokeaha haven't replied to #2373.
I believe that both of those PRs would be fine to keep, but they're even more fine to keep now :)
# Objective
- Describe the objective or issue this PR addresses.
- added openSUSE Tumbleweed deps that i needed to install today 2021-06-22
## Solution
- Describe the solution used to achieve the objective above.
- added info to doc
# Objective
I wanted to send the Bevy discord link to someone but couldn't find a pretty link to copy paste
## Solution
Use the vanity link we have for discord
Adds an GitHub Action to check all local (non http://, https:// ) links in all Markdown files of the repository for liveness.
Fails if a file is not found.
# Goal
This should help maintaining the quality of the documentation.
# Impact
Takes ~24 seconds currently and found 3 dead links (pull requests already created).
# Dependent PRs
* #2064
* #2065
* #2066
# Info
See [markdown-link-check](https://github.com/marketplace/actions/markdown-link-check).
# Example output
```
FILE: ./docs/profiling.md
1 links checked.
FILE: ./docs/plugins_guidelines.md
37 links checked.
FILE: ./docs/linters.md

# Improvements
* Can also be used to check external links, but fails because of:
* Too many requests (429) responses:

This PR adds a note to the Fedora section of Linux Dependencies on solving linker errors.
Fixes#1815.

The g++ package may not be preinstalled.
Also, replaced the mention of "fast" compiles, with generic instructions about how to install clang; this is because on my test system, clang didn't make any difference, and it's likely not to do any in general, as it is a relatively small part of the build.
Closes#1294.
That override was added to support pre 1.45 Versions of Rust, but Bevy requires currently the latest stable rust release.
This means that the reason for the override doesn't apply anymore.
I have run the VSCode Extension [markdownlint](https://marketplace.visualstudio.com/items?itemName=DavidAnson.vscode-markdownlint) on all Markdown Files in the Repo.
The provided Rules are documented here: https://github.com/DavidAnson/markdownlint/blob/v0.23.1/doc/Rules.md
Rules I didn't follow/fix:
* MD024/no-duplicate-heading
* Changelog: Here Heading will always repeat.
* Examples Readme: Platform-specific documentation should be symmetrical.
* MD025/single-title
* MD026/no-trailing-punctuation
* Caused by the ! in "Hello, World!".
* MD033/no-inline-html
* The plugins_guidlines file does need HTML, so the shown badges aren't downscaled too much.
* ~~MD036/no-emphasis-as-heading:~~
* ~~This Warning only Appears in the Github Issue Templates and can be ignored.~~
* ~~MD041/first-line-heading~~
* ~~Only appears in the Readme for the AlienCake example Assets, which is unimportant.~~
---
I also sorted the Examples in the Readme and Cargo.toml in this order/Priority:
* Topic/Folder
* Introductionary Examples
* Alphabetical Order
The explanation for each case, where it isn't Alphabetical :
* Diagnostics
* log_diagnostics: The usage of inbuild Diagnostics is more important than creating your own.
* ECS (Entity Component System)
* ecs_guide: The guide should be read, before diving into other Features.
* Reflection
* reflection: Basic Explanation should be read, before more advanced Topics.
* WASM Examples
* hello_wasm: It's "Hello, World!".
In this case, the previous section header linked to in second badge in `plugins_guidelines` didn't actually exist, so I just linked to the same section as the first badge
Also I need to check that github handles the relative links correctly
Changed grammar and wording on two entries to make them easier to understand and fit better into the context (make MP3 format fit better alongside the audio formats).
