Microsoft released another small update to the Skype app on Windows Phone 8.1 this week, but this appears to be a minor update with no new features included.
The update brings the app up to version 220.127.116.11, but the published change log is old. That usually means Skype for Windows Phone has received some bug fixes and performance improvements. If you happen to notice anything interesting in this update please let us know in the comments.
Thanks to everyone for the tips!
