mIRC is a full featured Internet Relay Chat client for Windows that can be used to communicate, share, play or work with others on IRC networks around the world, either in multi-user group conferences or in one-to-one private discussions.
A new and improved Log Files dialog has been added that allows you to search
log files and to view them in a window in mIRC.
A Clear History dialog has been added to the Tools menu that allows you to clear
the history of a number of features.
File transfers now display progress bars in different colors to indicate
DCC Send transfer speed has been improved.
A "UTF-8 encode/decode messages" option has been added to the Messages dialog to
enable or disable UTF-8 encoding/decoding of server messages.
The DNS routines have been changed to only request IPv6 if you are using
features that require it, which should speed up connections for some users.
And much more - there are around fifty changes in total in this release.
