How to upgrade to Phoenix from 0.6.x to 0.7.0.

1. 0.7.0 depends on Plug HEAD, so you'll need to include plug in your mix deps until the next plug release:

{:plug, github: "elixir-lang/plug", ref: "7040c89cb4cf1f1c6afdee379e5982a07d77a6c3"}
```

  1. The `Pheonix.Controller` functions html/2, json/2, text/2, redirect/2 and render/3 no longer halt automatically. *Important*: You must now explicity call `halt/1` yourself if you want to stop invoking further plugs after calling these functions. This is improtant for auth filtering plugs, ie:

```elixir

class Foo
  def initialize(attrs)
    @x = attrs.fetch(:x)
    @y = attrs.fetch(:y)
    freeze
  end
end

Using OTP's observer (appmon replacement) remotely

$ ssh remote-host "epmd -names"
epmd: up and running on port 4369 with data:
name some_node at port 58769

Note the running on port for epmd itself and the port of the node you're interested in debugging. Reconnect to the remote host with these ports forwarded:

$ ssh -L 4369:localhost:4369 -L 58769:localhost:58769 remote-host

#!/usr/bin/env ruby

# A sneaky wrapper around Rubocop that allows you to run it only against
# the recent changes, as opposed to the whole project. It lets you
# enforce the style guide for new/modified code only, as opposed to
# having to restyle everything or adding cops incrementally. It relies
# on git to figure out which files to check.
#
# Here are some options you can pass in addition to the ones in rubocop:
