Changelog

The following changes are required if you are upgrading from the previous
version:

• Users
  • ember new diff
  • Upgrade your project's ember-cli version - docs
• Addon Developers

Notes:

• This version of Ember CLI no longer supports Node.js v0.10 per the Ember Node.js LTS Support policy.
• As part of this release we have experimental support for including Ember from npm via the ember-source npm package. We hope to discover the gaps during this release cycle and make that the default in a future release.
