## Unreleased

### Breaking Changes

- `@wordpress/boot`, `@wordpress/route`, `@wordpress/theme`, and `@wordpress/private-apis` are no longer bundled. They are now expected to be provided by WordPress Core (7.0+) or the Gutenberg plugin.

### Enhancements

- Avoid unexpected results when typecasting `IS_GUTENBERG_PLUGIN` and `IS_WORDPRESS_CORE` values to Booleans ([#75844](https://github.com/WordPress/gutenberg/pull/75844)).
