> * Probably the biggest thing is the asset pipeline. It does
> everything from compiling languages (like SASS) to uglifying js
> code. Check out more info at
> http://guides.rubyonrails.org/asset_pipeline.html
> * New migration features. You no longer have to write up/down methods
> for the most part. Instead you just write "change" methods. More
> info at http://guides.rubyonrails.org/migrations.html
> * Multiple levels of has_many :through
> * Create key value stores in the database
> (http://blog.rawonrails.com/2012/02/using-activerecordstore-with-rails-32.html)
> * New active record methods like pluck
> (http://api.rubyonrails.org/classes/ActiveRecord/Calculations.html#method-i-pluck)
> * Scoped mass assignment. Helpful for locking down attributes per
> permission.
> (http://launchware.com/articles/whats-new-in-edge-scoped-mass-assignment-in-rails-3-1)
> * Slow query logger
> http://weblog.rubyonrails.org/2011/12/6/what-s-new-in-edge-rails-explain/.
> I've used http://explain.depesz.com/ to help analyze query explain
> output from postgres.
> * Encrypted fields (passwords, etc)
> http://railscasts.com/episodes/270-authentication-in-rails-3-1
> * New generator stuff. You can do "rails g scaffold Person name
> email" instead of "rails g scaffold Person name:string
> email:string". Or if you want to be really crafty: rails g scaffold
> Person name:index email:uniq.
