Problem

This is a tracking issue for when "official" io.js support comes to Express 4.x and 3.x. As of now, support for io.js is not completely known, but if there are issues, please open a new issue and they will be fixed, even before "official" support. Official support will not arrive until https://github.com/iojs/io.js/issues/269 or something similar is resolved; Express needs to be able to specify engine compatibility on installation.

Solution: io.js support

Low Risk

3.20.0, the last 3.x that will ever have an enhancement like this, will be released 2/18. This will not make it into the 3.x series, but that series does support Node.js 0.12, so it'll support io.js as long as it functions with Node.js 0.12 code.
