Babel-polyfill versions 6.6.0 and 6.6.1 are closely related iterations of a package designed to bring modern JavaScript functionalities to older environments, enabling developers to use the latest ECMAScript features without worrying about compatibility issues. Both versions share the same core dependencies: core-js for polyfilling a wide range of ES features, babel-regenerator-runtime to support async/await syntax, and babel-runtime for helper functions used by the Babel compiler. The license remains MIT, ensuring broad usability and freedom. Sebastian McKenzie is the listed author for both versions.
However, the key difference lies in their release dates, with version 6.6.1 being published on March 1, 2016, shortly after version 6.6.0, released on February 29, 2016. From a developer's perspective, this suggests that version 6.6.1 likely includes minor bug fixes or optimizations over 6.6.0. While the specific nature of these changes isn't detailed in the provided metadata, the rapid succession of releases indicates that the updates in 6.6.1 are likely important, albeit possibly small. Developers using babel-polyfill should consider upgrading to version 6.6.1 to benefit from these potential improvements, ensuring they're using the most refined and stable patch available within the 6.6.x series. The package essentially serves as a bridge, enabling cross-browser compatibility and supporting cleaner code writing using cutting edge features.
