Version Details and Security Vulnerabilities

@storybook/addons version 6.3.1 represents a minor update to the Storybook ecosystem, building upon the foundation laid by version 6.3.0. Both versions provide a central hub for Storybook addons, facilitating the extension of Storybook's functionality. Crucially, both maintain compatibility with React versions 16.8.0 and 17.0.0, ensuring a smooth upgrade path for existing projects using those React versions.

The core dependencies, such as @storybook/api, @storybook/router, @storybook/theming, @storybook/channels, @storybook/core-events, and @storybook/client-logger, are all aligned with their respective Storybook version. The move from 6.3.0 to 6.3.1 updates these internal dependencies to their respective 6.3.1 versions ensuring better internal consistenty. This is crucial for developers seeking stability and feature parity within the Storybook environment.

Developers will notice that version 6.3.1 likely includes bug fixes and minor improvements over 6.3.0 in the linked dependencies, however without specific release notes on the updates this cannot be confirmed. It is advisable for developers to upgrade to 6.3.1 to leverage these enhancements and maintain a consistent Storybook environment. Both versions retain all the features in previous releases such as managing addon state, communication between addons and Storybook and access to the Storybook API. Users already on Storybook 6.x.x should thus experience minimal disruption while receiving improvements using the later of the two package versions. Because of this seamless integration, version updates within the same major release should be a simple process, and should be performed by software developers regularly.
