+
+Today the Ember project is releasing version 4.8 of Ember.js, Ember Data, and Ember CLI.
+
+This release kicks off the 4.9 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](https://github.com/ember-cli/ember-try) addon is a great way to continuously test your projects against the latest Ember releases.

+### Changes in Ember.js 4.8
+
+Ember.js 4.8 is an incremental, backwards compatible release of Ember with bug fixes, performance improvements, and minor deprecations.
+
+#### Bug Fixes
+
+Ember.js 4.8 introduced 1 bug fix.
+
+- [#20166](https://github.com/emberjs/ember.js/pull/20166) - fixed a bug where calling RouteInfo.find() method executes callback with undefined object since 4.3.0.
+
+#### Features
+

+
+- [#20180](https://github.com/emberjs/ember.js/pull/20180) - an opt-in preview of public types for Ember is now available. This is meant to serve as a way to get early feedback, in line with Ember's normal path to stabilizing features. Users can opt into the types here, but no one will be interacting with these types automatically. Please see the [pull request](https://github.com/emberjs/ember.js/pull/2018) for more detail on the implementation and mechanics involved.
+
+#### Deprecations
+
+Ember.js 4.8 introduced 0 deprecations.

+
+## Ember Data
+
+Ember Data is the official data persistence library for Ember.js applications.
+

+
+## Ember CLI
+
+Ember CLI is the command line interface for managing and packaging Ember.js applications.
+
+### Upgrading Ember CLI
+
+You may upgrade Ember CLI using the `ember-cli-update` project:
+
+```bash
+npx ember-cli-update
+```
+
+This utility will help you to update your app or addon to the latest Ember CLI version. You will probably encounter merge conflicts, in which the default behavior is to let you resolve conflicts on your own. For more information on the `ember-cli-update` project, see [the GitHub README](https://github.com/ember-cli/ember-cli-update).
+
+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 `ember-source` and `ember-data`.

+## Thank You!
+
+As a community-driven open-source project with an ambitious scope, each of these releases serves as a reminder that the Ember project would not have been possible without your continued support. We are extremely grateful to our contributors for their efforts.
