# Objective - `apply_system_buffers` is an unhelpful name: it introduces a new internal-only concept - this is particularly rough for beginners as reasoning about how commands work is a critical stumbling block ## Solution - rename `apply_system_buffers` to the more descriptive `apply_deferred` - rename related fields, arguments and methods in the internals fo bevy_ecs for consistency - update the docs ## Changelog `apply_system_buffers` has been renamed to `apply_deferred`, to more clearly communicate its intent and relation to `Deferred` system parameters like `Commands`. ## Migration Guide - `apply_system_buffers` has been renamed to `apply_deferred` - the `apply_system_buffers` method on the `System` trait has been renamed to `apply_deferred` - the `is_apply_system_buffers` function has been replaced by `is_apply_deferred` - `Executor::set_apply_final_buffers` is now `Executor::set_apply_final_deferred` - `Schedule::apply_system_buffers` is now `Schedule::apply_deferred` --------- Co-authored-by: JoJoJet <21144246+JoJoJet@users.noreply.github.com>
