"[5] On July 13, 2007, Carsten V. Munk (stskeeps),[6] the founder of the UnrealIRCd project,[7] announced that a future v4.0 would be a fork of InspIRCd.

[9] In October 2015 it was announced that due to the many changes the new series will be called UnrealIRCd 4 and the first Release Candidate was made available for download.

[12] Some of Unreal's features are referred to as "nonstandard",[5] in that they are not listed in the IRC-related RFCs 1459 and 2811–2813,[13] but are beneficial "from a security point of view.

[citation needed] The "Firefox XPS" cross-protocol JavaScript-based attack on IRC networks was reported in January 2010;[24] UnrealIRCd developers later released a patch to set its anti-spoofing configuration parameter to "on" - the default was previously "off" - and "kill/zline/etc such connections".
