Instagram appears to be rolling out a batch interesting new features to at least some of its Windows Phone app users. Included in the update, which bumps the app from version 10.707.48352 to 10.738.64166, is support for Boomerang, hands-free and night mode in the camera portion of the app. You can check out a before and after look at the changes in the screenshots below.
The Boomerang option is similar to how it works in other versions of the app, allowing you to create short loops out of your videos. Meanwhile, night mode should adjust the sensor to take better images in low light, while hands-free lets you record video without holding down the capture button.
Before you get too excited about checking out these new goodies, however, it looks like this rollout is either extremely limited or accidental. So far, we've only been able to grab the update on an HP Elite x3 running a Windows 10 Mobile production (non-Insider). We've checked for the update on a Lumia 950, 950 XL, Alcatel Idol 4S and Lumia 640 in various Insider and Production configurations, but have only received it on the Elite x3.
That said, these features could be rolling out only to a specific group of devices for now. Another possibility is that it's an accidental rollout of some sort. For now, let us know in the comments if you've received the update, along with what phone you're using and whether you're on production of an Insider ring. Again, you'll want to look for version number 10.738.64166.
