NPM v3.0.0 Beta

THIS IS BETA SOFTWARE. npm@3 will remain in beta until we're confident that it's stable and have assessed the effect of the breaking changes on the community. During that time we will still be doing npm@2 releases, with npm@2 tagged as latest and next. We'll also be publishing new releases of npm@3 as [email protected] and [email protected] alongside those versions until we're ready to switch everyone over to npm@3. We need your help to find and fix its remaining bugs. It's a significant rewrite, so we are sure there still significant bugs remaining. So do us a solid and deploy it in non-critical CI environments and for day-to-day use, but maybe don't use it for production maintenance or frontline continuous deployment just yet.
