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.

Changelog:
1.Added UPnP support. The Ports dialog allows you to enable UPnP support for retrieving your external IP address, the identd server, DCC connections, and the DCC server. The first three options are enabled by default.

mIRC marks UPnP ports that it opens as "mIRC". It closes UPnP ports the moment they are no longer needed.

If mIRC is connecting to multiple servers at the same that use both IPv4 and IPv6, the UPnP port for the identd server will only be able to handle either IPv4 or IPv6 at any one time, since a UPnP port can only be bound to one address.

If you make any changes to the UPnP options in the Ports dialog, mIRC performs a quick check to see if UPnP is available and will warn you if it is not.

2.Added /socklisten -p switch to enable UPnP support for a listening socket.
3.Changed hotlink feature to handle more formats.
4.Fixed /clear -g switch bug.
5.Optimized display routine to use bitmap caching more efficiently.
6.Changed the way a server connection is closed after sending /quit to make disconnection more robust/graceful.
7.Added check for empty servers list. If servers list is empty, mIRC looks for the "defaults" folder and copies the servers.ini from there to the data folder.
