For those who use Skype on Windows Phone, a new update just went out to the Store. Version 220.127.116.11 is live and although the changelog mentions new 'compact design' that is actually the older one from back in January.
From a cursory look at the update, nothing stands out as different. That means this update is likely some bug fixes and optimizations for an improved experience.
Let us know in comments if you noticed anything different. Otherwise, head to the Store to grab it for your phone now.
