+  Thanks to this change, Capacitor dependencies are now properly linked to the project's TypeScript configuration. That means you won't have to install dependencies twice, once in `/src-capacitor` and once in the root folder. So, you can remove the Capacitor dependencies from the root `package.json` file. From now on, installing Capacitor dependencies only in the `/src-capacitor` folder will be enough.
