Phoenix 1.4 ships with exciting new features, most notably with HTTP2 support, improved development experience with faster compile times, new error pages, and local SSL certificate generation. Additionally, our channel layer internals receiveced an overhaul, provided better structure and extensibility. We also shipped a new and improved Presence javascript API, as well as Elixir formatter integration for our routing and test DSLs.

This release requires few user-facing changes and should be a fast upgrade for those on Phoenix 1.3.x.

Install the new phx.new project generator

The mix phx.new archive can now be installed via hex, for a simpler, versioned installation experience.

To grab the new archive, simply run:

#!/usr/bin/env bash

git ls-files db/migrate/*.rb | sort | tail -1 | \
  ruby -e "schema_version=STDIN.read[/\d+/]; init_schema=%(db/migrate/#{schema_version}_init_schema.rb);
  %x(git rm -f db/migrate/*.rb;
  mkdir db/migrate;
  git mv db/schema.rb #{init_schema};
  rake db:migrate;
  git add db/schema.rb; git commit -m 'Squashed migrations')"

# The purpose of this gist is to propose use of inheritance when upgrading objects to have "more functionality".

# For example:

#  Lets say you have a `company` model and your project manager purposes a huge pivot to your existing application.  
#  Now new fields are "required" for the new companies you create.  Unfortunately adding validators to the existing 
#  `company` model will cause things to blow up.  You could create a form object for the new forms with form specific 
#  validators.  Several issues are now introduced:
  
#  1) There can be several form objects for the company.  Each with a slight difference in logic.
