Deprecation Guide for Using amd bundles

Ember will no longer publish legacy AMD-specific Ember builds. To opt-in to consuming Ember as ES modules and clear this deprecation, enable the ember-modules optional feature by running ember feature:enable ember-modules.

This applies only to the classic build system or to Embroider < 4.0 without the staticEmberSource: true option. If you see this deprecation warning in these setups, please open an issue.

Alternatively, you can also clear the deprecation by moving to Embroider v4 by running the Ember Vite Codemod, but this may require additional changes to your project.

The AMD-specific Ember builds will no longer be published in next Ember major release

and no longer be bundled into vendor.js, even on the classic build system. These files are:

• ember.debug.js

• ember.prod.js

• ember-testing.js

• ember-template-compiler.js

• In rare cases, Addons were relying on accessing Ember from vendor. If you have addons that do so they will need to be updated to consume Ember as ES modules.

A known addon that previously relied on accessing Ember from vendor is ember-cli-deprecation-workflow. Please ensure you are on the latest version of this addon as that reliance has been removed.
