Replacement for jsdom in Node.js

jsdom 4 has discontinued support for Node.js.

From the documentation:

Note that as of our 4.0.0 release, jsdom no longer works with Node.js™, and instead requires io.js. You are still welcome to install a release in the 3.x series if you are stuck on legacy technology like Node.js™.

(I've heard about the criticism around Joyent's management of Node.js, but the "legacy technology" here sounds a bit derogatory.)

While jsdom 3.1.2 still works fine, I would like to build new projects on a library that receives regular updates and supports Node.js. Is anybody aware of an alternative project that is still maintained by its authors?
