Deprecation Guide for Deprecate import ComputedProperty from @ember/object/computed

ComputedProperty (the default export of @ember/object/computed) is deprecated. It was the internal class backing classic computed properties.

Migration

Do not construct or refer to ComputedProperty directly. Use native getters with @tracked state instead.

Before:

import ComputedProperty from '@ember/object/computed';
// rarely used directly

After: Remove the import; refactor any custom meta-programming to simple getters.

There is no public replacement for the class itself; the concept is removed.
