# Objective - Better consistency with `add_systems`. - Deprecating `add_plugin` in favor of a more powerful `add_plugins`. - Allow passing `Plugin` to `add_plugins`. - Allow passing tuples to `add_plugins`. ## Solution - `App::add_plugins` now takes an `impl Plugins` parameter. - `App::add_plugin` is deprecated. - `Plugins` is a new sealed trait that is only implemented for `Plugin`, `PluginGroup` and tuples over `Plugins`. - All examples, benchmarks and tests are changed to use `add_plugins`, using tuples where appropriate. --- ## Changelog ### Changed - `App::add_plugins` now accepts all types that implement `Plugins`, which is implemented for: - Types that implement `Plugin`. - Types that implement `PluginGroup`. - Tuples (up to 16 elements) over types that implement `Plugins`. - Deprecated `App::add_plugin` in favor of `App::add_plugins`. ## Migration Guide - Replace `app.add_plugin(plugin)` calls with `app.add_plugins(plugin)`. --------- Co-authored-by: Carter Anderson <mcanders1@gmail.com>
