Photosynth is Microsoft's proprietary photo app for taking 360 degree panoramas, and although it took a long time to arrive for Windows Phone 8, the app hasn't been updated in 14 months. Yes, time flies, but tonight version 1.7 has hit the Store in a rare treat for Windows Phone users.
Version 1.7, unfortunately, does not bring any new features though it does say 'bug fixes' for a changelog. Considering the multitudes of new devices and even a brand new operating systems (Windows Phone 8.1), it's not too surprising that Photosynth could use a little polishing.
Regardless, if you've never tried Photosynth, it's certainly worth the download as it's one of a kind on Windows Phone. Hopefully Microsoft hasn't forgotten about the app, especially after the high profile departure of Agüera y Arcas, an engineer who helped develop Photosynth.
Thanks, Jose M., and Ayushmaan W., for the tips!
