The new CLI, version 3, introduces several features such as clean and readable tables, fuzzy select menus, automatic confirmation of Y/n prompts, and better documentation. Despite some challenges during the development process, the team is happy with the final result and excited about its potential to improve future development and create new integrations with other tools and services. The article provides a detailed account of the development process, highlighting the benefits of Rust in this context and the improvements made to the CLI.
