Increase node version floor and cut new major once QUERY is supported?

[jonchurch]

The fallback methods in https://github.com/jshttp/methods/blob/master/index.js#L22 do not encompass the new QUERY method.

We could use code to include it if the Node version you're running includes it, but I think a new major would be more appropriate if we have differences in http.METHODS between node majors. Not sure this has ever happened before.

See expressjs/express#5615

That list of methods in this module is only supposed to be the ones supported by Node.js 0.10. If you are going to make a ner major, drop 0.10 and remove that static list, as it is only needed for supprt Node.js 0.10. That is less stuff to maintain

[dougwilson]

And at that point, why bother with the module, just use the http module exports directly in express and stuff. This module was only made for shimming Node.js 0.10 support

I think this can be closed considering we're dropping this module for Express v5, see #127
