Deprecation Guide for Clobbering Addon#options

Clobbering this.options within an addon has been deprecated. If you would like to use this.options for internal options within your addon, you must preserve the intitial options object that is present.

Instead of doing this:

included() {
  this.options = { my-addons: { special: { options: 'here' } } };
}

You should do the following:

included() {
  this.options = this.options || {};
  this.options['my-addons'] = { special: { options: 'here' } };
}
