  Socket.io 1.0                                            | [@mikermcneil](https://github.com/mikermcneil)                                   | upgrade to Socket.io 1.0
  Lock + unlock app in dev env                             | [@mikermcneil](https://github.com/mikermcneil)     | Capability for a hook to "lock" and/or "unlock" the app (in a development env only).  When "locked" all requests are intercepted by an endpoint which responds with either a page or JSON payload communicating a custom message.  e.g. so the grunt hook can let us know as it syncs.  e.g. `sails.emit('lock')`
  Hook dependency/load order mgmt                          | [@mikermcneil](https://github.com/mikermcneil)                                   | rebase the hook dependency+optional depenency system originally proposed by @ragulka

  Break out core hooks into separate modules               | [@mikermcneil](https://github.com/mikermcneil)                                   | Makes Sails more composable, and removes most of its dependencies in core. Also allows for easier sharing of responsibility w/ the community, controls issue flow
