Version Details and Security Vulnerabilities

@storybook/addon-viewport version 6.3.12 offers developers a refined tool for building responsive components directly within the Storybook environment. Functionally, both versions 6.3.11 and 6.3.12 share the core capability of enabling viewport adjustments, allowing developers to simulate different screen sizes and orientations to ensure components render correctly across diverse devices. The dependency structure remain largely identical, depending on core libraries such as global, core-js, and prop-types, alongside Storybook's internal packages for API, addons, theming, components, core events, and client logging. Both of the versions depends on the same peer dependencies.

The key differentiation lies in the internal updates within the Storybook ecosystem and fixes, reflected in the bump of dependency versions from 6.3.11 to 6.3.12 for packages like @storybook/api, @storybook/addons, @storybook/theming, @storybook/components, @storybook/core-events, and @storybook/client-logger. For developers, upgrading to 6.3.12 ensures they are leveraging the latest patches and enhancements within Storybook itself. While the unpacked size and file count remains the same, the newer release date of 2021-10-14 signal a more recent incorporation of improvements. Developers seeking the most up-to-date and stable experience should opt for version 6.3.12, benefiting from the cumulative refinements made within the Storybook platform.
