Now that app updates are resuming in the Store, Microsoft has pushed out a new build of their native camera app for Windows 10. So far, we only see the update on our phones, but it may be coming out for PC users as well. Edit: We now see it for PC too.
We have not noticed any differences yet, but the build shifts from 2015.1215.41 to 2016.107.11 and is likely tied to optimizations in the .63 OS update that went out recently. Likewise, there may also be improvements for those on the Lumia 950 and Lumia 950 XL, who have received the new firmware recently.
If you notice any fixes, improvements or oddities let us know in comments.
