Deprecation Guide for Base URL

The usage of baseURL setting in config/environments.js has been deprecated in favor of using an explicit rootURL. A detailed explanation of the problem and the migration path can be found in this blog post.

Migration for pre-2.7 applications is:

1. Update config/environment.js to remove reference to baseURL and update to rootURL.
2. Update app/index.html to add {{rootURL}} a the beginning of all assets that are loaded.
3. Update the app/router.js to pass rootURL to the subclass of Ember.Router being created.
