Version 4.2.0 Details

Babel-runtime versions 4.2.0 and 4.1.1 offer essential self-contained runtime support for Babel-transformed JavaScript, enabling developers to use modern ES2015+ features in their code while ensuring compatibility with older environments. Both versions, maintained by Sebastian McKenzie and housed within the Babel project on GitHub, serve the critical role of providing polyfills and helper functions necessary for Babel's transpiled code to execute correctly across different JavaScript engines.

The key difference between these versions lies in the enhancements and fixes incorporated between the two releases. Version 4.2.0, released on February 18, 2015, follows version 4.1.1, which was released a day before on February 17, 2015, suggesting it likely contains bug fixes, performance improvements, or potentially support for new language features introduced or refined in Babel's core transpiler during that period. While specific changelogs or release notes for these minor version updates are not readily available, developers should typically upgrade to the newer version (4.2.0 in this case) to benefit from the latest optimizations and resolved issues. Babel-runtime allows developers to ship smaller bundles, as the helpers are referenced rather than inlined into every compiled file. The tarball URLs provided enable easy access to download and integrate into projects via npm. Choosing the right version depends on the specific Babel configuration and desired level of compatibility for the target environment.
