The Ionic CLI has been enhanced with features that streamline app development, notably with the introduction of LiveReload functionality which allows developers to test changes on devices in real time without needing to rebuild the app for minor adjustments. This feature works via web sockets and supports console and server logs, aiding in debugging on actual devices or emulators. Additionally, the CLI now integrates with Codepen, simplifying the process of starting new Ionic projects based on Codepen demos by automatically parsing and organizing code into the correct project structure. These updates aim to make Ionic app development more efficient, with improvements in documentation and command-line help to guide users through the new capabilities.
