Windows Live Messenger users have a little over a month before they're assimilated into the Skype collective. Before then, the team has been busy preparing Skype for the influx of new users that will be flooding in throughout April.
Skype announced that version 6.3 is now live for its Windows client. It's a "maintenance release" which means that you won't be seeing any major new features added, but the fixes contained therein are sure to make Skype a more stable and friendlier experience:
Despite all of the above fixes, Skype 6.3 does have one little problem. The software can no longer display birthday notifications on Windows. There is no current workaround, but it shouldn't be too much of a concern. You probably spend a lot of time on Facebook, and it will make sure that you see every birthday notification.
If you don't have a Skype account yet, you can grab the latest version here. If you do, it should download the update the next time you open the software.
