After releasing Ember 3.6 last month, the team behind the Ember project released version 3.7 of Ember.js, Ember Data, and Ember CLI, last week. As always, Ember 3.7 embarks the start of 3.8 beta cycle for all the subprojects. This version drops support for Babel 6 and Node 4, along with a few bug fixes and performance improvements. There are no changes in the Ember Data subproject.

Updates in Ember.js 3.7

In Ember.js 3.7, the support for Node 4 has been dropped explicitly and if you want to upgrade to this version you need to first upgrade your Node version. Also, Node 6 support is planned to end in the next few months.

Updates in Ember CLI

  • The last usage of Babel 6 removed: The last usage of Babel 6 is removed in Ember CLI 3.7. Babel 6 was used for supporting compiling templates in addon/. It was also used for supporting addon-test-support/ in the addons that do not have any .js processors. Since the module compilation between Babel 6 and Babel 7 is compatible, this update is not a breaking change.
  • Compatibility section in addon README: Another update is a Compatibility section in addon README. Whenever a new addon is generated using Ember CLI, a README file is also generated for the addon. This README will now come with a compatibility section, which enables you to easily communicate to users about what are the requirements to use the addon.

You can upgrade to Ember CLI using the following commands:

npm install -g ember-cli-update
