Deprecation Guide for Legacy support addons

until: 3.0.0
id: legacy-support-addons

Ember provides addons ember-legacy-views and ember-legacy-controllers that allow for projects to continue using some legacy concepts in 2.x. Beginning in 2.4, use of these addons is now deprecated.

See the deprecation guide sections on removing views, ArrayController, and ObjectController for information on migration.

Once view and controller deprecations are removed, you can remove the addons with the command: npm uninstall --save-dev ember-legacy-views && npm uninstall ember-legacy-controllers
