+Today the Ember project is releasing version 5.3 of Ember.js, Ember Data, and Ember CLI. <!-- Block start: Uncomment if an LTS candidate --><!--This release of Ember.js is an LTS (Long Term Support) candidate. LTS candidates prioritize stability over the addition of new features, and have an extended support schedule.--><!-- Block end -->
+
+This release kicks off the 5.3.1 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.

+
+<!-- Block start: If there were no deprecations, remove this block -->
+
+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.
+
+Consider using the [ember-cli-deprecation-workflow](https://github.com/mixonic/ember-cli-deprecation-workflow) addon if you would like to upgrade your application without immediately addressing deprecations.

+
+## 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`.
+
