Apple has released the fourth iOS 10.1 beta which includes the Portrait camera for iPhone 7 Plus that applies a DSLR-like blur effect over photos using the dual lens system. iOS 10.1 beta 4 is available to registered developers. The fourth beta is also available to public beta testers on iOS 10.1 today.

Portrait mode is a feature that was demonstrated at Apple’s keynote earlier this month, but the major new feature wasn’t ready for primetime when the iPhone 7 Plus initially launched. Portrait still isn’t in the release versions of iOS, but developer and public betas released last month include a beta version of the feature which works well already.

Aside from Portrait mode, we noted the changes includes in the first beta last month:

There’s a new toggle setting in Accessibility called Auto-play Message Effects. This is related to Reduce Motion disabling Messages bubble and screen effects but the functionality does not seem to be implemented yet.

According to the developer release notes, iOS 10.1 includes a fix for motion handling. Developers will be able to access barometric pressure data for iPad Air 2, iPad mini 4 and iPad Pro.

For the impressive new Portrait mode in Camera, we went hands on with the new feature using the beta in our initial walkthrough. Zac also wrote about the new feature here and took some example images here. Check out Jeff Benjamin’s video demonstration below:

The previous version, iOS 10.1 beta 2, included changes to Messages and other bug fixes.

Although iOS 10.1 beta 4’s release notes don’t note any new features or changes, be sure to let us know if you find anything!
