Version Details and Security Vulnerabilities

@storybook/theming is a core library within the Storybook ecosystem, providing essential theming capabilities for building visually consistent and appealing user interfaces within Storybook environments. Versions 8.6.6 and 8.6.5, while seemingly minor releases, represent incremental improvements in this crucial theming infrastructure. The primary difference between the two versions lies in their release dates: version 8.6.6 was published on March 15, 2025, while version 8.6.5 was released on March 14, 2025. This suggests that 8.6.6 likely contains bug fixes, performance enhancements, or very minor feature tweaks implemented after the release of 8.6.5.

For developers using @storybook/theming, both versions ensure compatibility with Storybook versions 8.2.0 and above, including pre-release versions of 8.3, 8.4, 8.5, and 8.6, as indicated by the peerDependencies. This broad compatibility allows for flexibility in choosing Storybook versions. The consistent fileCount and unpackedSize between versions indicate that the core file structure and the amount of code in the final package stayed the same. Developers looking to integrate or upgrade @storybook/theming should prioritize the newer version (8.6.6) to benefit from the latest refinements and improvements. The library, distributed under the MIT license and hosted on GitHub, welcomes community contributions and benefits from Storybook's Open Collective funding.
