id Software's Paul Jaquays updated his .plan today with a clarification for those wondering how the recently updated GTKRadiant (story) relates to Q3Radiant (and QERadiant before it) as well as some words of appreciation for those that contributed to its development. Here's what he has to say:

I’ve seen this on some news pages, but it deserves more than just a mention in passing. Earlier this year, id passed on the maintenance and continuance of the map-making tools for Quake III Arena to a group of dedicated and involved community programmers. Like Robert Duffy before them, who turned id’s Quake 2 editing tool into what became QeRadiant, this group of hobbyists improved on id’s Quake III Arena editing tool, Q3Radiant, worked with mod and plug-in authors to improve its usefulness and versatility and eventually, in conjunction with Lokigames, transformed Q3Radiant into GTKRadiant, a cross-OS tool that would work on WinX and Linux systems.

The package released yesterday, as a public beta test, includes a version of GTKRadiant for WinX systems that will support both Q3A and Quake III: Team Arena ... including the new map area sizes and terrain functions. It also includes a number of support textures, models, manuals, and plug-ins provided by id and a number of 3D game making hobbyists. All in all, it may be one of the best 3D game making tool packages you’ll find anywhere, for any game, for any price. And thanks to the enthusiasm and generosity of the folks involved, that price is only the cost of a download.
