Babel-runtime provides self-contained runtime support for Babel-compiled code, enabling developers to use features like async/await and generators without polluting the global scope. Version 6.0.12, released on October 30, 2015, offers a subtle but potentially important upgrade over the previous stable version, 6.0.8, released a day earlier on October 29, 2015. At its core, functionality remains consistent through both versions with core-js dependency remaining "^1.0.0".
Notably, the devDependencies have shifted. Version 6.0.12 depends on newer versions of Babel's internal tooling: babel-helpers "^6.0.12" (up from "^6.0.2"), babel-plugin-transform-runtime "^6.0.7" (drastically up from "^1.0.7"), and babel-template "^6.0.12" (up from "^6.0.2"). Regenerator stays the same at "^0.8.34". While these development dependencies don't directly impact the runtime behavior of code using babel-runtime, these upgrades indicate potential improvements in the code transformation process. Developers using babel-runtime indirectly benefit from the increased efficiency and bug fixes by Babel's team with the upgraded tooling improving the reliability during development. While the core functionality delivered to end users remained similar, the updated devDependencies make this version a more robust solution.
