Which version should I use?

[julian]

v0.8.x confirmed working on Node v0.12
Upcoming v0.9.x works on v4 and probably v5.

I'm install NodeBB v0.8.2.
A recent version of nvm.
For node.js I use node 0.12.x

And so far works well.

For details you can inspect package.json of NodeBB : https://github.com/NodeBB/NodeBB/blob/master/package.json#L88
