Today Apple seeded the fifth beta of iOS 8.2 to developers. While nothing too significant seems to have been added, there are some updates to WatchKit.

Apple’s API for the forthcoming Watch debuted in the first iOS 8.2 beta, and it’s been getting updates with each beta release.

Developers can now create Settings bundles for their WatchKit extensions running in the iOS Simulator. There are some other code additions and enough known issues to make it seem like this won’t be the last 8.2 beta we’ll see.

Apple’s release notes also mention Wi-Fi calling on T-Mobile. Once iOS 8.2 ships, users will be able to activate the feature under the Phone section of the Settings app. The iPhone’s carrier name will read “T-Mobile Wi-Fi” in the status bar while activated.

The Apple Watch will ship in April, which means iOS 8.2 will have to be out by then with support for third-party Watch app extensions.
