Since when does Node.js offer ES6 classes?

EcmaScript 6 has been published in 2015. In which version were ES6 classes introduced in Node.js? I couldn't find the related github commit.

I'd like to know which was the first Node.js version allowing to use the class keyword as syntactical sugar for prototypes.

This is the last release I found which you can use for backwards compatibility testing: https://nodejs.org/download/release/v0.12.18/
