Upgrade Phoenix Framework

The following shows a minor upgrade within version 1.5.x. If you need to upgrade 1.4.x to 1.5.x, please see: https://gist.github.com/chrismccord/e53e79ef8b34adf5d8122a47db44d22f

To upgrade a Phoenix project, edit mix.exs, look for the line (was upgraded from 1.5.1 to 1.5.4):

{:phoenix, "~> 1.5.4"},

To upgrade the Phoenix installer itself, run in the terminal (example shows upgrading phx_new 1.5.3 to phx_new 1.5.4):

> mix local.phx

> mix deps.get
> mix
