# Objective - The current implementation for dynamic plugins is unsound. Please see #11969 for background and justification. - Closes #11969 and closes #13073. ## Solution - Deprecate all dynamic plugin items for Bevy 0.14, with plans to remove them for Bevy 0.15. ## Discussion One thing I want to make clear is that I'm not opposed to dynamic plugins _in general_. I think they can be handy, especially for DLC and modding, but I think the current system is the wrong approach. It's too much of a footgun for the meager benefit is provides. --- ## Changelog - Deprecated the current dynamic plugin system. - Dynamic plugins will be removed in Bevy 0.15. For now you can continue using them by marking your code with `#[allow(deprecated)]`. ## Migration Guide If possible, remove all usage of dynamic plugins. ```rust // Old #[derive(DynamicPlugin)] pub struct MyPlugin; App::new() .load_plugin("path/to/plugin") .run(); // New pub struct MyPlugin; App::new() .add_plugins(MyPlugin) .run(); ``` If you are unable to do that, you may temporarily silence the deprecation warnings. ```rust #[allow(deprecated)] ``` Please note that the current dynamic plugin system will be removed by the next major Bevy release, so you will have to migrate eventually.
