I.R.C. is Internet Relay Chat.
XChat runs on most BSD and POSIX compliant operating systems.

What's New:

Fixed being able to DCC resume while using the \"Save As...\" dialog on Windows 98.
Fixed connecting to a IRC server via proxy (bug in 2.6.5 only).
Fixed a rare crash, if you accepted a DCC using the Uploads & Downloads window but then clicked OK in the \"Save As...\" dialog after the transfer was completed.
Added an option of using \'Last-Spoke\' nick completion order in Settings > Input Box.
Fixed a crash if you left a Ban-List window open after closing the associated channel and then clicking Refresh
