Work on the 1.08 update continues behind the scenes. We’re changing the way the folder structure works in TDM to prepare for going standalone, and that is requiring a lot of extra time. Version 1.08 will not be fully standalone; it will run without Doom3, but most missions won’t load properly without Doom 3 assets.
There will also be many noticable improvements in 1.08, including a much richer sound experience, new characters, more forgiving AI, and improvements to object physics. A full changelog is here: 1.08 Changelog
