Pidgin is an instant messaging program for Windows, Linux, BSD, and other Unixes. You can talk to your friends using AIM, ICQ, Jabber/XMPP, MSN Messenger, Yahoo!, Bonjour, Gadu-Gadu, IRC, Novell GroupWise Messenger, QQ, Lotus Sametime, SILC, SIMPLE, and Zephyr.
Pidgin can log in to multiple accounts on multiple IM networks simultaneously. This means that you can be chatting with friends on AIM, talking to a friend on Yahoo Messenger, and sitting in an IRC channel all at the same time. Pidgin supports many features of the various networks, such as file transfer, away messages, and typing notification. It also goes beyond that and provides many unique features. A few popular features are Buddy Pounces, which give the ability to notify you, send a message, play a sound, or run a program when a specific buddy goes away, signs online, or returns from idle; and plugins, consisting of text replacement, a buddy ticker, extended message notification, iconify on away, spell checking, tabbed conversations, and more.
Sean: 2.2.0 contains the results of several major Google Summer of Code branches bringing some new, extraordinary features. We have a new protocol, MySpaceIM, a bunch of new features for an existing protocol, XMPP, and nifty new certificate management to make sure your IM server is who it says it is.
Ka-Hing: A number of you noticed crashes when dragging windows around when certain options are enabled. Well, that was my fault, and Sadrul fixed it. So Props to him and poos to me. I haven’t done much for this release, but the next one should contain something that I helped work on. Hint: students are cheap slave coders!
Kevin: I haven’t really been coding much in Pidgin, and this release is no exception, but I will be working on getting our wonderful web site to be a little more functional by next release. I promise!
