v0.4.0: May 22, 2014

• Added support for nested phrase objects to extend() and in the phrases option in the constructor.

v0.3.0: August 6, 2013

• Breaking change: Removed pluralize() method; instead, just use the t() method, passing in a smart_count option.
• Breaking change: Removed the ability to use Array, Backbone.Collection, etc. instances for the smart_count option; instead, must pass a Number.

• Added allowMissing option to let the phrase key be the default translation (thanks @ziad-saab).

v0.2.0: Dec 20, 2012

• Breaking change: Moved from Singleton pattern to class-based. Now you create an instance of the Polyglot class rather than using class methods directly on it. The reason is to allow maintaining multiple sets of phrases, which is something we ran into at Airbnb with a highly-concurrent Express app.
• Breaking change: Removed the built-in Handlebars helpers, because Handlebars is a singleton, and it's messy to create a single helper function that can be bound to different Polyglot instances. Instead, it's super easy to create your own, based on your requirements.
