A full version history of the babel-polyfill package with size, number of distributed files and dependency evolution.
Babel-polyfill, a crucial JavaScript library, provides essential polyfills enabling older browsers to support modern JavaScript features (ES2015+). Examining its version history reveals a pattern of continuous improvement and adaptation to evolving JavaScript standards. The initial versions, starting from 6.0.2 in October 2015, focused on core ES6 features and relied on dependencies like core-js and regenerator. Early releases saw rapid iterations (6.0.14, 6.0.16, 6.1.4, 6.1.17, 6.1.18, 6.1.19), indicating active development and bug fixes.
Mid-lifecycle versions (6.2.0 onward) show Babel-polyfill aligning more closely with specific versions of its core dependencies like core-js and regenerator-runtime, ensuring better compatibility and stability. The introduction of babel-regenerator-runtime as a dependency highlights the increasing sophistication of handling asynchronous code. Further versions (6.9.0, 6.9.1) saw updates to core-js and regenerator-runtime. Later versions like 6.13.0, 6.16.0, 6.20.0 and beyond showcase the project's commitment to maintaining a comprehensive polyfill environment. The final version in the provided dataset, 6.26.0 (August 2017), uses the latest versions of all its dependencies like core-js and focused on providing a complete ES2015+ support. The constant updates to its dependencies, and the addition of babel-regenerator-runtime, show constant active development, and that the project is up to date with Javascript standards.
