Version Details and Security Vulnerabilities

@storybook/addon-essentials package saw a minor update from version 6.0.20 to 6.0.21. Both versions, designed to enhance Storybook with curated addons, share the same core functionality and target audience: developers seeking to streamline their Storybook experience. The dependencies are also almost identical, including core-js, ts-dedent, and other vital Storybook addons like @storybook/api, @storybook/addons, @storybook/addon-docs, @storybook/node-logger, @storybook/addon-actions, @storybook/addon-controls, @storybook/addon-toolbars, @storybook/addon-viewport and @storybook/addon-backgrounds. Furthermore, the development dependencies and peer dependencies remain consistent, indicating no significant changes in the development or runtime environment. Developers can expect a similar development experience concerning React compatibility, Babel loader, and testing.

The key difference lies in the internal updates and potential bug fixes released between August 28th, 2020 (version 6.0.20) and August 31st, 2020 (version 6.0.21). While the direct impact on the API or features might be minimal, upgrading to version 6.0.21 ensures access to the latest improvements and stability enhancements within the @storybook/addon-essentials package. Both versions maintain the same MIT License, repository, file count, and unpacked size. Therefore, the primary reason to upgrade is to benefit from the accumulated bug fixes and micro-optimizations contained within the few days of development, promising an overall smoother experience for those utilizing Storybook.
