The Ember project is excited to announce the release of Ember v6.9. This is a standard minor release as part of the standard Ember Release Train process. Version 6.8 of Ember.js is now promoted to LTS (Long Term Support). An LTS version of Ember continues to receive security updates for 9 release cycles (54 weeks) and bugfixes for 6 cycles (36 weeks). LTS releases typically occur every four minor versions. The previous LTS version of Ember.js was 6.4.

Ember.js v6.9

All changes in Ember.js 6.9 were internal, docs, and/or bugfixes that were backported.

Ember CLI v6.9

Ember CLI 6.9 upgrades broccoli to ^4.0.0 and as a consequence, the minimum Node version Ember CLI supports is now 20.19. This is in accordance with our Node Support Policy.

We have released a new major of broccoli to address security vulnerabilities and deprecations in dependencies of the package. These vulnerabilities should not have been exploitable as broccoli should only ever be run in a development environment but this fixes a number of npm audit headaches. There is more work to do here in updating our long-tail of dependencies. The major of broccoli is otherwise completely API-compatible. We have dropped support for node < 20.19 because we need the require(esm) feature that was backported to that version.

Thank You!

As a community-driven open-source project with an ambitious scope, each of these releases serves as a reminder that the Ember project would not have been possible without your continued support. We are extremely grateful to our contributors for their efforts.
