Version Details and Security Vulnerabilities

Version 5.3.9 of @storybook/theming, a core component library for Storybook, introduces a minor update over the previous stable version, 5.3.8. Both versions share the same core dependencies crucial for theming and styling Storybook components, including polished for advanced CSS-in-JS utilities, @emotion/core and @emotion/styled for efficient styling solutions, and emotion-theming for managing themes within the Emotion ecosystem. Furthermore, both versions rely on ts-dedent to work with multiline strings when writing code, and deep-object-diff for object comparisons. The global dependency that provides NodeJS Globals, core-js to make sure the code is compatible with older browsers and memoizerific for memoization which helps with perfomance. These dependencies highlight the commitment to performance and modern styling practices within Storybook.

Notably, the only discernible difference between the two releases lies in the @storybook/client-logger dependency. Version 5.3.9 is using version 5.3.9 of the client-logger while version 5.3.8 of theming relies on version 5.3.8 of the client logger. This signifies a synchronized update within the Storybook ecosystem, likely addressing bug fixes or minor improvements within the logging mechanism. Developers leveraging @storybook/theming can expect consistent performance and theming capabilities between these two versions, with 5.3.9 offering the latest refinements in client-side logging. The tarball size is the same for the 2 versions and both were released in January 2020, with a few days of difference.
