Today the Ember project is releasing version 3.7 of Ember.js, Ember Data, and Ember CLI. This release kicks off the 3.8 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.

Ember.js is the core framework for building ambitious web applications.
Changes in Ember.js 3.7
Ember.js 3.7 is an incremental, backwards compatible release of Ember with bugfixes, performance improvements, and minor deprecations. There is zero (0) new feature, zero (0) deprecations, and three (3) bugfixes in this 3.7 version.
Note that in Ember.js 3.7 support for Node 4 has been explicitly dropped. Node 4 is no longer supported by the Node.js team either, and that Ember CLI had already dropped support in early 2018. This means that if you are on Node 4 and want to upgrade you will need to upgrade your version of Node first.
Node 6 support is planned to end in the next few months. Keep an eye on the release posts for more information on this.
New Features (0)
There are no new features in Ember.js 3.7.
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 addon if you would like to upgrade your application without immediately addressing deprecations.

Upgrading Ember CLI
You may upgrade Ember CLI easily using the ember-cli-update project:
npm install -g ember-cli-update ember-cli-update
This utility will help you to update your app or add-on 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 undo the changes to the lines containing

Compatibility section in addon README (1 of 2)
Whenever you generate a new addon using Ember CLI it will automatically generate a README file for your addon. With Ember CLI 3.7 this README will now include a compatibility section that will allow you to easily communicate to users of the addon what is needed to use the addon.
Remove last usage of Babel 6 (2 of 2)
Ember CLI 3.7 has removed the last usage of Babel 6 which was used for supporting compiling templates in
addon/ and supporting
addon-test-support/ in addons that themselves do not have any
.js processors (e.g. no dependency on
This change is not a breaking change since the module compilation between Babel 6 and Babel 7 is compatible.
No new deprecations introduced in Ember CLI 3.7.
