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, MySpaceIM, 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.
Pidgin can work with:

o Our bundled libgadu should now build on HP-UX.
o Fix some instances of file transfers never completing. (Cristi Posoiu) (#12472)
o Sort by Status no longer causes buddies to move around when you click them.
o Fix embedding in the system tray on older GTK+ releases (such as on CentOS 5.5 and older Fedora).
o No longer require libstartup-notification for startup notification support. GTK+ has included support for years, so use it instead. (David Benjamin) (#13245)
o Fix a bug where some buddies from your buddy list might not show up. Affected non-English ICQ users the most. (#13386)
