Emesene 1.5 brings a lot of new features and bugfixes, most notable being the webcam (video) support. Changes in 1.5:

* Compatible with the latest Window Live Messenger(tm)

* HTTP connection and proxy support
* @msn accounts support

Previously, the way to connect to Twitter using Pidgin (IM client for yahoo, google talk, msn, etc), was to use a jabber account like google chat, then add Twitter. But Twitter shut down the Jabber service.  So it doesn’t work anymore. But now, Pidgin-microblog can do the trick.
