Apple isn't wasting any time getting its next major software updates ready.

One week after launching iOS 13.3.1, the first iOS 13.4 beta has been released to developers. Because this is the first beta release of iOS 13.4, there's no word yet on what changes are included, but we're expecting something a bit more substantial than iOS 13.3.1 since this is a 13.x release.

If you've registered with Apple as a developer, you can grab this update over the air by going into Settings > General > Software Update. You also have the option of pointing your computer's web browser to Apple Developer Center.

Also released today is the first beta for watchOS 6.2. Again, since this is the first beta release, there's no word yet on what changes might be included. We should learn more in the coming weeks as more betas are released and people have time to dig into the new updates.

UPDATE: Now that iOS 13.4 and watchOS 6.2 betas are getting installed on users' devices, we're getting some info on what changes Apple has packed into the updates.

iOS 13.4 beta 1 includes iCloud Folder Sharing and an updated toolbar in the Mail app with rearranged icons like Delete, Flag, and Folder. There are nine new Memoji stickers, too, such as a shocked face, a face with hearts, and eyes rolling.

Other notable iOS 13.4 changes include new iPad keyboard shortcuts in Photos, universal iOS/macOS purchases, new third-party navigation and call controls for CarPlay, and a CarKey API that'll allow an iPhone or Apple Watch to unlock, lock, and start a compatible car.
