@storybook/addons package versions 6.4.1 and 6.4.0 represent incremental updates to Storybook's addon management system. Both versions serve the essential function of providing a centralized store for Storybook addons, facilitating the discovery, installation, and management of these extensions which enhance Storybook's functionality. Each addon provides functionality to extend Storybook features to increase the developer experience.
While the core functionality remains consistent, the key difference lies in the version bumps of the internal Storybook packages on which @storybook/addons depends. In version 6.4.1, dependencies like @storybook/api, @storybook/router, @storybook/theming, @storybook/channels, @storybook/core-events, and @storybook/client-logger are all updated to version 6.4.1, aligning them with the @storybook/addons version. In version 6.4.0, all of those are in the version 6.4.0 too. This suggests that 6.4.1 incorporates bug fixes, performance improvements, or minor feature enhancements within those individual packages.
Developers should upgrade to 6.4.1 to benefit from these cumulative improvements within the Storybook ecosystem. The peer dependencies on react and react-dom remain the same across both versions. This ensures compatibility with React versions 16.8.0 and 17.0.0. So, a seamless upgrade is expected. Developers can always reference the Storybook changelog for a detailed breakdown of the changes introduced in each minor release and understand the specific fixes or enhancements included.
