Pidgin is a chat program which lets you log in to accounts on multiple chat networks simultaneously. This means that you can be chatting with friends on MSN, talking to a friend on Google Talk, and sitting in a Yahoo chat room all at the same time.
Pidgin runs on Windows, Linux, and other UNIX operating systems.
Pidgin is compatible with the following chat networks out of the box: AIM, ICQ, Google Talk, Jabber/XMPP, MSN Messenger, Yahoo!, Bonjour, Gadu-Gadu, IRC, Novell GroupWise Messenger, QQ, Lotus Sametime, SILC, SIMPLE, MySpaceIM, and Zephyr. It can support many more with plugins.
Pidgin supports many features of these chat networks, such as file transfers, away messages, buddy icons, custom smilies, and typing notifications. Numerous plugins also extend Pidgin's functionality above and beyond the standard features.
Pidgin integrates with the system tray on Windows.
o Fix misparsing a web message as an SMS message. (Yuriy Kaminskiy)
o Increase NS command history size to prevent crashes on buddy lists that have a lot of buddies on other networks like Yahoo!
o Accounts with empty buddy lists are now properly marked as connected.
o Fix receiving messages from users of MySpace IM's web client.
o Fixed phantom online buddies. They should now properly disappear when signing out.
o Fixed the crashes some users were seeing with cn.scs.msg.yahoo.com in 2.5.7.
o Fixed compiling on systems with glib 2.4.x or older.
o Fixed an issue with file transfers. This may not resolve all issues, but it should resolve at least some of the most common ones.
o The pager server will automatically update to scsa.msg.yahoo.com if the user empties the field or if it is scs.msg.yahoo.com. This should ease the pain of transition to the new login method.
o Fix an incompatibility betweeen Prosody and libpurple clients.
