s/pull/15

Philosophy

"Stability without stagnation": incremental changes, givepeople time with deprecations

Simplification and intuify

Borrow data-flow idea from React.js: data flows in,events go out

Easier attribute binding

HTML-syntax for components

Remove context switching from templates

One-way binding will be default

Routeable components

When entering a route:

Ember 1.x: creates controller, view, template

Ember 2.0: creates component, template (old way will stillwork)

Easier actions
