The software engineers at PTGui have been working on a new update of this popular imaging program. What is interesting is that they are going to support some of the newer 360 cameras like the Gear 360, Xiaomi Mijia Sphere and the Yi 360 VR
I know you can already use the current version to stitch fisheye images but it requires some manipulation. I'm assuming by support they mean including camera details within the PTGui lens database etc.
As many of these new cameras seem only to have their own editing software in Windows, Mac users will be able to use PTGui for stills.
PTGui have a forum on Google Groups.
No date on final release as yet.
