Today the Ember project is releasing version 4.11 of Ember.js, Ember Data, and Ember CLI.
This release kicks off the 4.12 beta cycle for all sub-projects. We encourage our community (especially addon authors) to help test these beta builds and report any bugs before they are published as a final release in six weeks' time. The ember-try addon is a great way to continuously test your projects against the latest Ember releases.

Changes in Ember.js 4.11
Ember.js 4.11 is an incremental, backwards compatible release of Ember with bug fixes, performance improvements, and minor deprecations.
Ember.js 4.11 introduced 0 bug fixes.
Ember.js 4.11 introduced 2 features.
- Stable TypeScript types for the
@ember/ownerpackage (first released in 4.10).
- Stable TypeScript types for the
Both of these packages already had types available as part of the public preview types, so you might wonder: What is new here? The answer is: these are the first type definitions generated from Ember's own TypeScript source code, instead of written by hand. This means that these types are guaranteed to match Ember's own behavior: they literally cannot get out of sync.
If you are already using the public preview types, as documented in the announcement post, you don't have to do anything. If you would like to opt into using the new stable and preview types, you can add this to your project (e.g. in
Reminder: while these two packages are now stable, much of Ember's types are still in preview, and subject to change between minor releases. We expect to finish getting the rest of Ember's types stable, and therefore following Ember's normal stability rules, early in the upcoming 5.x releases!
Ember.js 4.11 introduced 0 deprecations.
Deprecations are added to Ember.js when an API will be removed at a later date. Each deprecation has an entry in the deprecation guide describing the migration path to a more stable API. Deprecated public APIs are not removed until a major release of the framework. No new deprecations are allowed after the
.10 release, to minimize churn before the next major release.
Consider using the ember-cli-deprecation-workflow addon if you would like to upgrade your application without immediately addressing deprecations.

Ember Data is the official data persistence library for Ember.js applications.
Ember Data 4.10, which was not released at the time of the broader Ember 4.10 release, has now been released and is essentially a re-release of Ember Data 4.9 with some fixes around
@ember/string deprecations. Ember Data 4.11.0 is also a re-release of Ember Data 4.10. However, there were several very important fixes shipped in Ember Data 4.11.1, 4.11.2 and 4.11.3 that users should be aware of.
Changes in Ember Data 4.11
Ember Data 4.11 introduced 0 bug fixes.
Ember Data 4.11.1 introduced 1 important bug fix for a bug around embroider compatibility that prevented users from using Ember Data in embroider Ember applications starting in Ember Data 4.8. The fix means that Ember apps using Ember Data can also use embroider again!
Ember Data 4.11.2 introduced 1 bug fix that addresses computed chains not updating in EmberData 4.8 and up.
Ember Data 4.11.3 introduced 1 bug fix that addresses an issue around infinite recursion in ember-concurrency and another involving SSR/test memory leaks.

Upgrading Ember CLI

ember-cli-update project, see the GitHub README.
While it is recommended to keep Ember CLI versions in sync with Ember and Ember Data, this is not required. After updating ember-cli, you can keep your current version(s) of Ember or Ember Data by editing
package.json to revert the changes to the lines containing
