Microsoft today updated their Photos app for Windows 10 devices in Windows Store. The updated Photos app version is 15.803.16240.0. There is nothing new in this release, so it must be just bug fixes that improves overall experience of the app.
The best place to enjoy, organize, edit, and share all your digital memories. It brings together photos and videos from all your devices, enhances them to make great photos even better, and organizes them into beautiful albums for you.
Update it here from Store.
Thanks to @fusionfan45 for the heads up.
