Version Details and Security Vulnerabilities

@babel/plugin-proposal-decorators version 7.17.9 represents a minor update over the preceding 7.17.8, primarily affecting internal dependencies. Developers relying on this Babel plugin to compile class and object decorators to ES5 should note the subtle changes. The key distinction resides in the updated dependencies. Notably, @babel/helper-create-class-features-plugin advances from version 7.17.6 to 7.17.9, potentially incorporating bug fixes or enhancements relevant to class feature transformations. Furthermore, the newer version includes @babel/helper-split-export-declaration at version 7.16.7, which did not feature in the older one.

Within the devDependencies, @babel/core sees an upgrade from 7.17.8 to 7.17.9, while @babel/traverse jumps from 7.17.3 to 7.17.9, suggesting improvements or patches applied to the core Babel transformation engine. The core functionality pertaining to decorator compilation remains consistent, with @babel/plugin-syntax-decorators staying at version 7.17.0. Developers already using the plugin might consider upgrading proactively; those encountering issues with class features are particularly encouraged to adopt version 7.17.9. The unpacked size also sees a minor increase from 45136 to 45510 bytes, hinting at the added or modified codebase from internal dependency updates.
