Babel plugin transform minify booleans, versions 6.9.3 and 6.9.4, are designed to optimize Javascript code by converting true and false boolean literals into !0 and !1 respectively. This seemingly small change can contribute to reduced file sizes, particularly when boolean values are used frequently throughout a codebase. Both versions, licensed under the MIT license, share the same core functionality, description, and author ("amasad"), indicating a high degree of similarity. They also have identical file counts (5) and unpacked sizes (1566 bytes). The key difference lies in their release dates: version 6.9.3 was released on May 14, 2018, at 13:53:27 UTC, while version 6.9.4 followed later the same day at 21:33:28 UTC.
For developers considering using this plugin, the near-identical nature of the two versions suggests that the update from 6.9.3 to 6.9.4 likely involves minor bug fixes, performance enhancements, or dependency updates that don't fundamentally alter the plugin's behavior. While a detailed changelog would be ideal for precise insights, the rapid succession of releases points toward a focused refinement. If you're using version 6.9.3, upgrading to 6.9.4 is generally recommended to benefit from any potential improvements, however, for most user the difference is negligible, and the upgrade can freely be ignored. The repository URL provided in the metadata points to the master branch of the babel/minify repository, allowing access to information about the plugin's source code and related issues/discussions.
