anchor.diff:            RFCs: Ember.js follows a community-driven process for its development that incorporates <a href="https://github.com/emberjs/rfcs">RFCs for features and deprecations.</a> An RFC is a Request for Comments. Before changes are made to Ember's API, they are proposed publicly and the community is asked to review and comment. Anyone can create an RFC, not just Core Team members. RFCs undergo many edits to incorporate community feedback. If a proposal has enough support, it is merged, meaning that work may begin to integrate the functionality into the codebase.

  -          Deprecations: The ember-cli informs developers of upcoming changes to the API via deprecation warnings. To see these warnings and <a href="http://emberjs.com/deprecations/">Deprecation Guides instructions</a> about how to resolve them, make sure you have the latest CLI. You can use newer CLI versions with older Ember app versions. It's a good idea to resolve deprecations as they arise, so that when new major versions are released, there is less overhead to upgrade.
