Gatsby v2.28 introduces a streamlined interactive experience to simplify the process of creating new Gatsby sites, addressing the overwhelming choice of over 2600 plugins and themes available. By enhancing the existing commands `npm init gatsby` and `gatsby-new`, the update offers a user-friendly wizard that guides developers through the setup by asking pertinent questions, allowing them to customize their site with desired features like CSS-in-JS systems or responsive images without needing prior knowledge of Gatsby-specific starters or plugins. This new workflow aims to make Gatsby more accessible to newcomers by reducing decision fatigue and ensuring easy setup with commonly used plugins while still offering the flexibility to configure additional plugins manually if desired.
