Version Details and Security Vulnerabilities

@storybook/addon-actions is a valuable tool for Storybook users, enabling them to log actions performed within their components for easy tracking and debugging. Versions 4.0.2 and 4.0.3 offer similar core functionality, both providing a way to display action dispatches within the Storybook UI. Examining the dependencies, the primary difference lies in the versions of other @storybook packages. Version 4.0.3 updates dependencies such as @storybook/addons, @storybook/components, and @storybook/core-events from 4.0.2 to 4.0.3, suggesting bug fixes, performance improvements, or new features within the core Storybook framework reflected in these updated dependencies in addon-actions 4.0.3.

For developers, this means upgrading to version 4.0.3 may resolve compatibility issues or unexpected behaviors encountered with earlier Storybook versions or these specific internal packages. If your Storybook setup already utilizes version 4.0.2 without issues, the upgrade to 4.0.3 might appear minimal in terms of immediate feature enhancements for action logging specifically, but it's crucial for staying aligned with the Storybook ecosystem and benefiting from underlying platform improvements. The size of the package increased negligibly between these versions, from 278397 to 278402 unpacked size, suggesting small bugfixes or internal changes within the dependency packages. For users experiencing problems with Storybook 4.0.2's core, upgrading to addon-actions 4.0.3 would be a sensible first step.
