Your plugin might depend on Bevy Main or the latest release. You can also do both on different branches (e.g., have a `bevy_main` branch). If you intend to track Bevy's main branch, you can specify the latest commit you support in your `Cargo.toml` file: ```toml -bevy = { version = "0.5", git = "https://github.com/bevyengine/bevy", rev="9788b386c7846c99978ab5c1a33698ec5a471d84", default-features = false } +bevy = { version = "0.5", git = "https://github.com/bevyengine/bevy", rev = "9788b386c7846c99978ab5c1a33698ec5a471d84", default-features = false } ``` You can specify the dependency [both as a version and with git](https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#multiple-locations). The version will be used if the dependency is pulled from [crates.io](https://crates.io/). Otherwise, the git dependency will be used. You can use one of these badges to communicate to your users how closely you intend to track Bevy's main branch. - - -|
