Windows Live Messenger Library 3.0 is capable of fueling faster IM's according to Microsoft. Version 3.0 of the library is available with the March 2009 release of the Messenger Web Toolkit, which was launched at MIX09. “The previous versions of the Messenger Library used session based messaging for IM conversations. As with any session based protocol there was a noticeable delay between the session initiation and the time the users could actually send messages. The newer version uses a new messaging feature that makes it possible to send messages without the need for creating a session,” Kumar said. “Additionally, the Messenger Library’s polling mechanism to fetch messages from Messenger has also been improved,” revealed Jeenandra Kumar.
