Today the Ember project is releasing version 6.2 of Ember.js and Ember CLI.

This release kicks off the 6.3 beta cycle for all sub-projects. We encourage our community (especially addon authors) to help test these beta builds and report any bugs before they are published as a final release in six weeks' time. The [ember-try](https://github.com/ember-cli/ember-try) addon is a great way to continuously test your projects against the latest Ember releases.

### Changes in Ember.js 6.2

- [20811](https://github.com/emberjs/ember.js/pull/20811) - fixes a type bug that prevented using the latest version of TypeScript.

## EmberData

EmberData is the official data persistence library for Ember.js applications.

EmberData [broke from Lockstep versioning in November 2023](https://blog.emberjs.com/updates-to-ember-data-versioning-strategy). Under the new policy, EmberData 5.3 is an LTS that supports `ember-source` 5.12 and `ember-source` 6.0. More compatibility info is available in the [README](https://github.com/emberjs/data#compatibility).

EmberData is also in the process of rebranding to WarpDrive. Stay tuned for more info!

This support extends beyond bug-fixes. If minor enhancements can be made to better support new presentation class implementations that support the 5.x series we will willingly accept them. Our goal is that we want no one left behind.

To learn about the motivation and goals for upcoming changes to EmberData in 5.x,
read the [blog post, EmberData 5.X Update](https://blog.emberjs.com/ember-data-5-x-update-2023-04-15/).

<!-- alex ignore retext-equality -->

This will help you form the mental model of what to expect across the 5.x series,
and understand deprecation removals in the context of the upcoming goals.

## Ember CLI

Ember CLI is the command line interface for managing and packaging Ember.js applications.

### Upgrading Ember CLI

You may upgrade Ember CLI using the `ember-cli-update` project:

```bash
npx ember-cli-update
```

This utility will help you to update your app or addon to the latest Ember CLI version. You will probably encounter merge conflicts, in which the default behavior is to let you resolve conflicts on your own. For more information on the `ember-cli-update` project, see [the GitHub README](https://github.com/ember-cli/ember-cli-update).

It is not required to keep Ember CLI versions in sync with Ember and EmberData. After updating ember-cli, you can keep your current version(s) of Ember or EmberData by editing `package.json` to revert the changes to the lines containing `ember-source` and `ember-data`.
