# Breaking changes in v23

- We extend the main configuration in this repo to cover `.js` (for codebases that still have React components defined in `.js`, not `.jsx`, files), as well as `.ts` (to cover rules like `react-hooks`, that do not report in `.ts` files under the existing configuration). Since this will result in a new set of reported errors, we are cutting a breaking version for visibility.
  - This may also report in plugins, if they are being manually configured, throwing errors due to duplicate registration. Those manual registrations can either be refined (depending on your configuration), or outright removed (the expected case).
