@storybook/addons version 5.3.15 represents a minor update to the Storybook addons package, building upon the preceding stable version 5.3.14. Both versions serve as the central hub for managing and registering addons within a Storybook environment, facilitating enhanced functionality and customization. Examining the dependency lists, we observe that version 5.3.15 upgrades several internal Storybook packages, specifically "@storybook/api," "@storybook/channels," "@storybook/core-events," and "@storybook/client-logger" from 5.3.14 to 5.3.15. This suggests the update focused on internal improvements and bug fixes within the Storybook ecosystem itself.
For developers utilizing Storybook, this update implies enhanced stability and potentially improved performance across addons. Because the core dependencies of the addons package have been upgraded, addon developers benefit from the fixes and functionalities in the API core and others. While the code size (unpackedSize and fileCount) remains identical between the two versions, the newer version likely resolves issues present in prior releases of the packages, such as the API or the client logger.
The upgrade would be important for users who found errors or oddities when using the previous version of the tool and can also be interesting for people working on new addons which want to benefit from the newest APIs.
