Support Node.js 4.x

[dougwilson]

This is a tracking issue regarding "official" support and testing of Node.js 4.x in Express 4.x :) Express 4.x is likely to work already on Node.js 4.x, but there could be potential edge cases, and we are working on getting all our dependencies tested for Node.js 4.x

I tested express prior to the release. All top level tests passed. Off the top of my head I can't think of anything that should effect express/deps other than this bug found by hapi: nodejs/node#2821

Is there anything keeping this open, or is Node 4 support "official?" Looks like that one found by hapi has been resolved that @Fishrock123 mentioned.

[dougwilson]

It is open until all our dependencies are tested and deemed fully functional on Node.js 4 and then Express updates to use the Node.js 4-verified versions of these dependencies. This is how we deal with all major Node.js/io.js releases.

Ah, I see =) Is there any ETA on that?

[dougwilson]

Hi @CWSpear , currently Express is maintained by 100% volunteers, so I don't think is any way to promise any kind of ETA. The most I can say is it's being worked on as fast as possible.

[CWSpear]

Alright, thank you.

@CWSpear And, I guess as an update to the original note, we have yet to find any dependencies that has an issue with Node.js and from what we have seen so far, we don't expect to find anything. This means that as far as I can tell, the current version of Express 4 (4.13.3) should not have any problems on Node.js 4.
