Ionic CLI v3 has been released, offering significant improvements in speed and guidance due to the reduction of dependencies and legacy code. The new version introduces a modular architecture through CLI plugins, allowing users to maintain a small core while adding specific functionalities as needed. This approach enhances the development process for various platforms like desktop and PWAs. The CLI provides interactive prompts and improved command help, and namespaces Cordova commands to accommodate the expanding scope of Ionic applications. Users are encouraged to upgrade by uninstalling the old CLI and installing the new version, ensuring they also install the appropriate plugins for their projects. Despite some known issues, including slow dependency downloads and configuration file changes, the release is supported by comprehensive documentation and community engagement through feedback and contributions.
