Babel-runtime versions 5.8.19 and 5.8.12 both serve as Babel's self-contained runtime environment, offering essential polyfills and helper functions for transformed code to execute smoothly across diverse JavaScript environments. Both depend on core-js (version ^0.9.0) for polyfilling newer JavaScript features and include babel-plugin-runtime (^1.0.7) and regenerator (^0.8.34) as development dependencies, aiding in the code transformation process. The packages are MIT licensed, underscoring their open-source nature and facilitating widespread adoption. Both version's author is Sebastian McKenzie.
The key distinction lies in the repository URL and the release date. Version 5.8.19 adjusted its repository URL to include "git+" prefixing the HTTPS address, presumably standardizing the Git URL format. More significantly, version 5.8.19 was released on July 29, 2015, while version 5.8.12 was released on July 28, 2015. This one-day difference suggests that version 5.8.19 likely incorporates bug fixes or minor improvements over 5.8.12, representing the latest refinements within the 5.8.x series at that specific point in time. Developers using Babel should opt for the newer version since it is generally advisable to utilize the most recent stable release within a given version branch in order to incorporate the latest bug fixes.
