@storybook/react versions 6.4.0 and 6.4.1 offer developers a robust environment for building React components in isolation, complete with hot reloading for rapid development. Both versions share the core functionality of Storybook, enabling component visualization and testing outside of the main application context. Developers can leverage features like addons, CSF (Component Story Format), and theming to create a comprehensive component library. Key dependencies like react-refresh, webpack, and babel are also present in both, ensuring compatibility with modern React development workflows.
However, subtle differences exist between these versions. The most notable is the update in internal Storybook packages. Version 6.4.1 updates the following dependencies: "@storybook/core", "@storybook/store", "@storybook/addons", "@storybook/node-logger", "@storybook/client-api", and "@storybook/core-common" from 6.4.0 to 6.4.1. Version 6.4.1 likely includes bug fixes, performance improvements, or minor feature enhancements within the Storybook ecosystem. Developers relying on specific behaviors in older Storybook packages should test their stories when upgrading, but overall the transition is expected to be seamless, since the release is a patch. If no problems arise, upgrading is suggested, since it contains the newest fixes and latest improvements. The other difference is the release date. Version 6.4.1 was released on 2021-11-30T00:37:37.804Z whereas version 6.4.0 was released on 2021-11-26T16:20:20.754Z.
