Version Details and Security Vulnerabilities

@storybook/addon-viewport is a valuable tool for Storybook users aiming to develop and test responsive components effectively. It enables developers to adjust Storybook's viewport size and orientation, simulating various devices and screen resolutions directly within the Storybook environment. This facilitates a streamlined workflow for ensuring components render correctly across different platforms.

Comparing version 6.4.3 with the previous stable version 6.4.2, the core functionality remains consistent, focusing on providing viewport control within Storybook. A primary difference lies in the internal dependencies. Version 6.4.3 updates the dependencies on core Storybook packages like @storybook/api, @storybook/addons, @storybook/theming, @storybook/components, @storybook/core-events, and @storybook/client-logger, all to version 6.4.3, aligning them with the addon's version. This likely includes minor bug fixes, performance improvements, and potentially new features within those core packages that the addon now leverages. The underlying dependencies like 'core-js', 'prop-types', 'memoizerific', and 'regenerator-runtime' remain the same, suggesting no significant changes in the fundamental JavaScript runtime or core utility functions utilized.

Developers upgrading from 6.4.2 to 6.4.3 can expect a smoother experience due to the synchronized versions of internal Storybook dependencies, potentially solving compatibility issues and ensuring optimal performance. While the core API and usage of the viewport addon are unlikely to change dramatically, staying updated with the latest version ensures access to the most recent bug fixes and improvements within the broader Storybook ecosystem. The "releaseDate" difference shows that version 6.4.3 was released shortly after 6.4.2, suggesting a quick fix or an important set of minor improvements over the previous version.
