Sep 3, 2025 – By Jared Galanis

Today the Ember project is releasing version 6.7 of Ember.js and Ember CLI.

A release of Ember is comprised of many projects: ember-source, ember-cli, and all the learning team projects. We follow a 6-week release train that includes alpha and beta cycles to ensure changes are well-tested. We encourage our community (especially addon authors) to help test the beta builds and report any bugs before they are published as a final release. The ember-try addon is a great way to continuously test your projects against the latest Ember releases. While we only consider the release to be complete upon publication of the blog post, the 6-week cycle is anchored by the release of the ember-source package at the beginning of the process. Releases x.4, x.8 and x.12 will become an LTS candidate, so checkout Ember LTS Releases if you want to know more.

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:

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.

It is not required to keep Ember CLI versions in sync with Ember and EmberData. After updating ember-cli, you can keep your current version(s) of Ember or EmberData by editing package.json to revert the changes to the lines containing ember-source and ember-data.
