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 addon is a great way to continuously test your projects against the latest Ember releases.

Upgrading Ember CLI
You may upgrade Ember CLI easily using the ember-cli-update project:
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.
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
Changes in Ember CLI 3.23
No significant changes were introduced in this version of Ember CLI. Upcoming changes to how the blueprint for new applications sets up testing were delayed to next minor version due to regressions.

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.
