@storybook/react version 9.1.3 is a minor release over 9.1.2, both serving as renderers for React components within the Storybook environment. Key differences appear in their dependencies. Specifically, @storybook/react-dom-shim is updated from version 9.1.2 to 9.1.3 to keep it aligned. Although the developer dependencies remain identical between the two versions, this update to the react-dom-shim might bring compatibility improvements or bug fixes specific to React DOM interactions, ensuring better rendering and behavior within Storybook.
A notable difference is in the dist section of the metadata. The unpackedSize has slightly increased from 1661158 bytes in version 9.1.2 to 1661247 bytes in version 9.1.3. This suggests that the new version likely introduces some new features, minor code additions or optimizations that caused an increase in the total size of the library. This aligns with the updated react-dom-shim dependency, hinting at internal improvements.
Moreover, the release dates provide insight into the recency of each version. Version 9.1.3 was released on August 21, 2025, while version 9.1.2 was released on August 11, 2025. Choosing version 9.1.3 ensures developers are leveraging the most up-to-date features, optimizations, and fixes officially provided by the Storybook team, while the peer dependencies remain the same.
