Microsoft Photos has received an update on Windows 10 Windows 10 Mobile this afternoon, but it seems to be a rather minor one. In checking the PC update, we aren't yet noticing anything new. The new version clocks in at number 15.1009.12140.0, and doesn't appear to bring anything new to the table. We have received tips that the update contains a new "Favorites" icon, along with a corresponding folder in albums view, however, but we haven't seen it on our end yet.
We'll continue to poke around and update this post if we notice anything new. In the meantime, be sure to shout out in the comments if you happen to see anything notable that we've missed!
Thanks for the tips, MP3Mike and Vinamra!
