Babel-runtime versions 5.0.6 and 5.0.5 are closely related iterations of a core package designed to provide self-contained runtime support for Babel-compiled JavaScript code. Both versions share the same fundamental purpose: enabling developers to utilize modern JavaScript features in their projects while ensuring compatibility across various JavaScript environments. Crucially, they each list core-js version "^0.8.0" as a dependency, indicating a shared reliance on this polyfill library for providing necessary ECMAScript standard library features. Both packages are authored by Sebastian McKenzie and can be found on the Babel Github repository and they are selfContained runtimes.
The main difference lies in their version numbers itself and release dates. Version 5.0.6 represents a subsequent, though minor, update to 5.0.5. Released just a few minutes after version 5.0.5, 5.0.6 likely includes bug fixes, minor performance improvements, or very subtle adjustments to the runtime code. For developers using babel-runtime, upgrading from 5.0.5 to 5.0.6 is generally recommended because even small updates can improve code stability and reliability. The tarball URLs in the dist object is the only way to effectively check the upgrade as there appear to not exist many changes in the metadata itself. Although these are old versions, they show how a package evolves incrementally in this very popular library.
