Based on user feedback from its June beta release, Skype has now rolled out the final 5.5 build of its software which is available for download immediately.
Skype 5.5 adds deeper Facebook integration in that you can view which of your FB friends are online from it directly as well as being able to instant message them from the new 'Facebook Contacts' tab. The ability to view and update your Facebook status is also possible as well as being able to view and 'like' posts from your wall directly from Skype Home.
Focusing more on Skype specific functions, there has been a number of updates made to improve general Skype calling with better controls for video and group video calling in Windows as well as more solid video calling reliability and some design changes to help make things a little easier in all.
A final worthy mention for emoticon loving folks on the new 5.5 update is that the emoticons have been updated with smoother and bolder/better quality animations as well as some new additions to the collection.
