Skype just launched version 5.3 of their Windows app. This update brings some features like improved video quality for Skype Mobile users, and better call quality on the desktop version. Apparently a user on one end at least needs to have Skype v5.3 for Windows installed to get better video calling functions. This is basically all you get with the new update.
Some improvements with your friends’ presence icons, automatic redialing after a failed call attempt(given the fact that the user’s phone number has been added to a profile) and some minor tweaks here and there can be found.
