Here's version 1.7 BETA 3 and there will be some more betas. In this version in Doom and Heretic I switched to Hexen-like line defs. I tried to do this in a ZDoom compatible way so Doom wad files converted with zwadconv runs in Vavoom. Also new demo levels for Doom and Heretic. WadAuthor config files and ACS script include files are included with demo levels. For next beta I will put attention on optimizing rendering to make it a little bit faster.
