Deprecation Guide for Deprecate Utility

Using the ember-cli/lib/utlities/deprecate module to issue deprecations has been deprecated in favor of using .writeDeprecateLine method on the ui object (which is available on both addons and project instances).

Migrate from:

const deprecate = require('ember-cli/lib/utilities/deprecate');

module.exports = {
  name: 'my-addon-name',

  someMethod() {
    deprecate('this thing is deprecated!');
  }
}

To:

module.exports = {
  name: 'my-addon-name',

  someMethod() {
    this.ui.writeDeprecateLine('this thing is deprecated!');
  }
}
