# Objective - Fixes #16892 ## Solution - Removed `TypeRegistryPlugin` (`Name` is now automatically registered with a default `App`) - Moved `TaskPoolPlugin` to `bevy_app` - Moved `FrameCountPlugin` to `bevy_diagnostic` - Deleted now-empty `bevy_core` ## Testing - CI ## Migration Guide - `TypeRegistryPlugin` no longer exists. If you can't use a default `App` but still need `Name` registered, do so manually with `app.register_type::<Name>()`. - References to `TaskPoolPlugin` and associated types will need to import it from `bevy_app` instead of `bevy_core` - References to `FrameCountPlugin` and associated types will need to import it from `bevy_diagnostic` instead of `bevy_core` ## Notes This strategy was agreed upon by Cart and several other members in [Discord](https://discord.com/channels/691052431525675048/692572690833473578/1319137218312278077).
