The latest version of Skype
Version: 18.104.22.168 was released today. The file is 22.6 MB.
The new version enables you to send and receive money directly from Skype with Send Money using PayPal.
You can also create instant profile pictures using video snapshot.
However, one of the improvements I really liked is the fact that I can now invite friends using MSN messenger, Gmail and Yahoo! Mail.
