+
+Today the Ember project is releasing version 3.23 of Ember.js, Ember Data, and Ember CLI.
+
+This release kicks off the 3.24 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 3.23
+
+Ember.js 3.23 is an incremental, backwards compatible release of Ember with bugfixes, performance improvements, and minor deprecations.
+
+Ember.js 3.23 introduced several bug fixes, including:
+
+- Updated Glimmer (rendering engine) to improve developer experience with debugging ([#19213](https://github.com/emberjs/ember.js/pull/19213))
+- Ensured that `(fn (mut ...))` works with falsy values ([#19221](https://github.com/emberjs/ember.js/pull/19221))
+- Fixed bugs in query parameters with intermediate transitions ([#19249](https://github.com/emberjs/ember.js/pull/19249))
+- Prevented multiple serialization of query parameters on `activeTransition` ([#19236](https://github.com/emberjs/ember.js/pull/19236))
+- Prevented dynamic invocation of string value when referenced directly in angle brackets ([#19122](https://github.com/emberjs/ember.js/pull/19122))
+- Issued a deprecation for tracked mutation in `constructor` during rendering ([#19282](https://github.com/emberjs/ember.js/pull/19282)) ⚠️

+
+## Ember CLI
+
+Ember CLI is the command line interface for managing and packaging Ember.js applications.
+
+### Upgrading Ember CLI
+
+<!--alex ignore easy-->
+You may upgrade Ember CLI easily 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`.
+
+### Changes in Ember CLI 3.23
+
+Blueprints for new applications were updated for the new testing setup ([#9340](https://github.com/ember-cli/ember-cli/pull/9340), [#9371](https://github.com/ember-cli/ember-cli/pull/9371/files)).

+## Thank You!
