Version 5.2.1 Details

Babel-runtime provides a self-contained runtime environment necessary for Babel-transformed code to function correctly. Versions 5.2.1 and 5.2.0, both released on April 30, 2015, within a short timeframe highlight the rapid iteration typical of the Babel ecosystem. While seemingly minor increments, even small version bumps can contain essential fixes or optimizations.

Developers using Babel to transpile modern JavaScript code for older environments rely on babel-runtime to polyfill missing features like Promises, generators, and other ES2015+ functionalities. This package ensures that transpiled code runs seamlessly across different browsers and Node.js versions. Given the extremely close release dates—approximately an hour apart—the difference between versions 5.2.0 and 5.2.1 likely involves a critical bug fix or immediate adjustment to the initial 5.2.0 release. Examining the specific commit logs around that timeframe on the Babel GitHub repository (github.com/babel/babel) would provide the clearest picture of the exact changes. Upgrading from 5.2.0 to 5.2.1 is highly recommended to gain the benefit of these immediate improvements and ensure smooth execution of transpiled JavaScript. Both versions depend on core-js version 0.9.0 or higher, a library that provides polyfills for many JavaScript features.
