The update fixes an annoying bug that you may have encountered if you have tried to use Photos on Build 10581. The bug makes the app crash when you access the “Folders” section. With this update the bug is fixed and now you can go to Folders in the app.
Have a look at the recently added features in the Photos app:
• Easily view photos at actual size • Share Lumia living images as video with anyone on any platform • Save photos from videos and edit rich capture images on Lumia phones • See the file name at top of viewer window • Set photos as favorites and see them on the Photos tile on Start (phone only) • Files in synced OneDrive folders load more quickly, and appear in Folders view (PC only) • More commands available on right-click or press-and-hold • Bug fixes
