Capacitor 3.0 introduces significant changes to its core plugins, where all officially supported plugins are now installed and versioned separately from the Capacitor core, giving developers more control over the APIs included in their apps and improving startup times. The migration to this new structure is straightforward, involving updating the app to the latest beta release of Capacitor Core, CLI, and platform-specific tools for iOS and Android. Developers are guided to update their import paths and directly access APIs from new packages, such as the File System API, enhancing the development experience. The Capacitor team is also collaborating with the Capacitor Community Github Org to update third-party plugins to align with the new API structure, with further content and updates promised in future posts.
