Ember 7.0 Released Show Site Navigation Blog
May 29, 2026 – Jared Galanis, The Ember project is excited to announce the release of Ember v7.0. Following Ember's Major Version Policy, the major includes only the removal of features that were deprecated until 7.0 as well as other bugfixes. This release of Ember.js means the previous version, 6.12, is now an LTS (Long Term Support) version. In Ember 6.1 we began publishing ember-source as a v2 addon, which enabled Embroider to consume ember-source directly. Ember v6.8 was the biggest change to how an Ember project is built in recent memory. The Ember Core Teams have been working on the Embroider+Vite build system and the strict-mode-templates (a.k.a template-tag) for literal years, and this is the first version that we made them the default experience for newly generated Ember apps. Early adopters have been opting into these features for quite some time, but generating an app with Ember v6.8 (or newer) now gives you an incredibly modern developer experience 🎉 Merged the glimmer-vm monorepo into ember.js to faciliate faster iteration on the rendering engine and the integration with ember.js. Thank you to all the contributors that helped make this major-version cycle possible! Consider upgrading addons used in your app to the latest version that you can. This will reduce the uses of deprecated APIs in your dependencies. For help or advice along the way, visit Ember's forums or chat groups. Removes import Ember from 'ember'. See the RFC or deprecations in your project for a guide on replacement APIs. For more details on how to resolve these deprecations in your app, see the deprecations guide. #21076 Support default globals for strict mode with the runtime template compiler per RFC #1070.

The release of Ember v7.0, announced on May 29, 2026, by Jared Galanis, Chris Manson, and Katie Gengler, follows the project's Major Version Policy, which dictates that major releases focus on removing deprecated features and implementing bugfixes. This release establishes Ember 6.12 as the Long Term Support Long Term Support (LTS) version. The project promotes a philosophy of introducing new features in minor releases to ensure backward compatibility, thereby minimizing the complexity of major upgrades for development teams. Significant evolutions occurred within the Ember 6.x series, introducing numerous notable features. In Ember 6.1, the project began publishing ember-source as a version 2 addon, integrating it directly with Embroider. Further expansions included adding support for template-tag components as route templates in version 6.3, and introducing a new application blueprint utilizing the Embroider and Vite-based build system as the default in version 6.8. Ember 6.8 also established strict-mode component authoring as the default and introduced the renderComponent API, enabling component rendering outside of a full project context. Furthermore, this version introduced tracked versions of JavaScript native collection types, including trackedArray, trackedObject, trackedMap, trackedSet, trackedWeakMap, and trackedWeakSet. The development of the 6.x series also involved extensive community contributions aimed at improving iteration speed and security. The team merged the glimmer-vm monorepo into ember.js to facilitate faster iteration on the rendering engine and integration with ember.js, and merged the router.js repository into ember.js to prepare for experimentation with new router architectures. Community efforts also focused on security, updating dependencies like broccoli to mitigate vulnerabilities, and actively reducing deprecation warnings. This cycle included the release of Glint v2, which formalized the template-tag component authoring format, and the creation of codemods for migrating to the new authoring and build systems. Upgrading to Ember 7.0 involves a structured methodology. The recommended path involves upgrading the application to the latest version of Ember 6, specifically 6.12, resolving all existing deprecation warnings, and then proceeding to version 7.0. For projects on earlier versions, a sequential upgrade through LTS versions such as 6.4, 6.8, and finally 6.12 is advised. This process requires careful attention, particularly when crossing major boundaries, such as the 6.8 demarcation, where configuration adjustments for ember-cli are necessary to ensure successful builds. Developers must address all deprecations, as these features are removed in Ember 7.0, and ensure that test suites pass without warnings, often utilizing tools like ember-cli-deprecation-workflow for managing complex migrations. Ember.js 7.0 itself focuses primarily on refining the existing codebase rather than introducing new public APIs. The release involves removing previously deprecated public APIs from the 6.x cycle and implementing numerous bug fixes. Specific changes include the removal of the direct import of Ember from ember, the cessation of AMD bundle publication by ember-source (an option can be opted into via specific feature flags), and a specific update in service consumption where the import now requires referencing service explicitly, such as import { service } from '@ember/service'. Notable bug fixes address strict mode configuration, tracked collection behavior concerning deletion, reactivity in tracked maps and weak maps, and fixes related to the LinkTo functionality. The Ember CLI v7.0 release is also minimal, introducing no new APIs, deprecations, or bugfixes, instead automatically breaking previously deprecated public APIs, which are slated for future cleanup. |
