Ember released version 4.0 of Ember.js, Ember Data, and Ember CLI. Ember’s 4.0 release focuses the framework by removing long-deprecated APIs and support for legacy platforms.

While Ember Octane APIs have been the default for new applications since Ember 3.15, the framework has continued to support “Classic” framework features in accordance with its semantic versioning commitment. Ember 4.0 takes a step forward and drops already-deprecated classic APIs, however the foundational EmberComponent and EmberObject / computed APIs are not removed in this release.

Notable changes in the Ember 4.0 release include:

For more details on the changes in Ember.js 4.0, please review the Ember.js 4.0.0 release page.

Want to hear about an added bonus? Hot ๐Ÿ”ฅ on the heels of 4.0, Ember 4.1 was also released this week and it introduced 3 features service export, refresh method from RouterServiceand a cached decorator. It also introduced the deprecation of AutoLocation. Ember Data and Ember CLI did not introduce notable changes. See more about the 4.1 release at.


Ember Ignite is an international virtual mini conference scheduled for Wednesday, February 23rd!

Many teams talk about the challenges of hiring and training Ember developers, and this conference tackles those challenges directly. Attendees will level up their training and teaching skills in order to build strong teams.

Tickets are donation-based with a suggested amount of $ 30 USD. Proceeds will go towards creating an open source curriculum for teaching Ember to junior developers and taking a live cohort of 10 junior engineers (with no experience) and teaching them Ember so well, that they’ll go toe-to-toe against mid-level UI engineer candidates. This effort is led by Jai Bhagat.

If you’re interested in hearing about how Ember is being used at LinkedIn in the LTS UI Infra team, you should check out the recent tweet thread ๐Ÿงต by Jordan Hawker (@ elwayman02).

Jordan calls out many of the impressive achievements that the team has been able to deliver thus far, in part due to the power of Ember ๐Ÿ”ฅ, and what is in store for 2022, including Embroider builds in production, completing Octane migrations, leveraging yarn workspaces and rolling out SSR!

You may want to check out the thread for all of these reasons, but an added bonus is that this team at LinkedIn is hiring so take a look if you’re in the market for a new position!


There’s a nice article by Bill Dami (@billdami) at Gavant describing why they chose Ember for their project and how it has benefited them! ๐Ÿ‘

Topics covered are the benefits of using a “batteries included” framework like Ember, how Ember contributes to developer happiness and some great detail on what made Ember the right fit for their project.

It’s always inspiring to read about how Ember benefits teams around the world and this article does provide some detailed and excellent points on the matter that really demonstrate how joyful it can be to develop with the right tools.

The key changes include:

  • Converting the entire package to ESM
  • Adding over a dozen rules to the recommended config
  • Removing deprecated rules, options, and behaviors
  • Dropping support for old versions of Node
  • Enforcing stricter default behavior for a few rules
  • Enforcing stricter validation of configuration files and rule tests

Version v1.0.0 of ember-focus-trap was recently released by Josemar Luedke (@josemarluedke) bringing some upgrades (to Ember 4!), enhancements (moving to v2 addon format and a monorepo setup) and bug fixes (removal of redundant code for return focus node).


There’s a cool ๐Ÿ˜Ž new polyfill for plain functions as modifiers by NullVoxPopuli (@NullVoxPopuli) you might want to check out!


There’s more content available at the great โœจ Glimmer Cheatsheet โœจ NullVoxPopuli (@NullVoxPopuli) has put together!

The cheatsheet has expanded its coverage of how templates work in Ember.js along with some super nice examples of the syntax and notation.

If you haven’t had a chance to check it out yet, go ahead and have a look, here!
