Well, not completely brand new, but rebranded.
You see, there was an open source instant messaging client called Gaim. Gaim had been around for a long time, and then AOL sued them. Gaim (the word) includes the letters ‘aim’, which AOL trademarked (you know, AOL Instant Messenger), but only after the Gaim team named their software.
Just last week the Gaim team changed the name of the project to Pidgin, a pretty cool name that hints on the interoperability of the Pidgin client, which connects to almost every im network. According to Wikipedia, a “pidgin is a simplified language that develops as a means of communication between two or more groups who do not share a common language.”
Pidgin supports most instant message networks, including AIM, Gadu-Gadu, Novell Groupwise, ICQ, IRC, MSN, QQ, SILC, SIMPLE, SameTime, XMPP (known as Jabber, and includes the ability to connect to Google Talk), and Yahoo! Messenger. This means you can connect to any network you want to talk to your friends and business colleagues, whatever network they use.
Pidgin is really cool software, and here are some screenshots of the new look:
PS- To run Pidgin on Windows you have to install it with the GTK+ toolkit (which is included with Pidgin). For Mac OSX, use Adium, which is a native Mac client based on Pidgin’s underlying toolkit (libpurple).
